X03026S2 FIGURE 1-3 Model 340F Differential Transmitter with Flange May 1998 1-5 INTRODUCTION UM340-1 Each transmitter is a microprocessor-based, self-contained pressure-to-current transducer. The heart of the transmitter is the MycroSENSOR™. Developed and patented by Moore Products Co., the MycroSENSOR is a silicon, dual-capacitance pressure sensor assembly. It generates a direct digital output signal that is proportional to input pressure. The direct digital output in conjunction with the microprocessor provides Direct Digital Processing (DDP™). DDP provides advanced processing and compensation for varying ambient temperature and static pressure. This yields improved performance, stability, and reliability compared to conventional analog transmitters. Although signal processing is digital, a transmitter can be configured to operate in either an analog mode or a digital mode, for a Point-to-Point or a Multi-Drop network, respectively. ANALOG MODE: A single transmitter is connected to a controller, recorder, or other field device. A loop known as a Point-to-Point network interconnects the instruments. Figure 1-4 shows a traditional application. Single-Loop Digital Controller X03028S0 2 Wire 4-20 mA 2 Wire 4-20 mA I/P Model 773 Model 352 H Model 340D Configured as a Transmitter Only Flow FIGURE 1-4 Traditional Application Figure 1-5 shows an application using the Model 340’s built-in controller function, with a Model 385 Loop Operator’s Station. Here the transmitter-controller’s 4-20 mA output is the valve signal, which is sent directly to the final control element. The measured variable and other variables are communicated to the Loop Operator’s Station using the HART protocol. Optional Loop Operator's Station 2 Wire 4-20 mA I/P Model 773 H Flow Model 340D Configured as a TransmitterController Model 385 X03027S0 FIGURE 1-5 Transmitter-Controller Application 1-6 May 1998 UM340-1 INTRODUCTION The HART® (Highway Addressable Remote Transducer) protocol is used for communication between the transmitter and a HART Communicator, a personal computer running configuration software, or another remote device. This is done by superimposing the HART digital signal on the analog current. Communications can transfer a new or edited configuration, remotely monitor the process variable, or service a transmitter. DIGITAL MODE: When the Model 340 is used only as a transmitter, 1-15 transmitters can be parallel connected to a Multi-Drop network using only twisted-pair cable. The HART protocol is employed to send all process variable information to a HART-compatible controller , recorder, or other device. A Model 340 can be equipped with an optional Smart Display™ (Figure 1-6) to permit local viewing of output variables and to make local configuration easier. Connection to the loop is made using a terminal board with three screw terminals (Figure 1-7), which is located on the opposite end of the transmitter enclosure from the Smart Display.

This section describes HART Communicator connections, liquid crystal display, keypad, and on-line and off-line menus. It also provides short overviews of some of the Communicator’s functions. The Communicator is shown in Figure 2-1. For information about the Communicator’s battery pack, Memory Module, Data Pack, and maintenance procedures, refer to the manual supplied with the Communicator. 2.1 INTRODUCTION From a wiring termination point, the HART Communicator interfaces with a Model 340 transmitter or other HART device using a 4-20 mA loop, provided a minimum load resistance of 250Ω is present between the Communicator and the power supply. The Communicator uses the Bell 202 frequency-shift keying (FSK) technique of high-frequency digital signals imposed on a standard transmitter current loop of 4-20 mA. Because no net energy is added to the loop, HART communication does not disturb the 4-20 mA signal. The Communicator can be used in hazardous and non-hazardous locations. WARNING Explosions can cause death or serious injury. Before connecting the HART Communicator in an explosive atmosphere, make sure that the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. Refer to the Communicator nameplate and the manual supplied with the Communicator for certifications and approvals before connecting. 2.2 COMMUNICATOR CONNECTIONS The Communicator can interface with a transmitter from the control room, the instrument site, or any wiring termination point in the loop. Connections are made through loop connectors on the Communicator’s connection panel (Figure 2-1). The connection panel also may have a jack for the optional NiCad recharger, and it has a serial port for a future connection to a personal computer (PC). To interface with a transmitter or other HART device, connect the HART Communicator in parallel with the instrument or load resistor. The connections are nonpolar. For intrinsically safe FM and CSA wiring connections, see the manual supplied with the Communicator. WARNING Explosions can result in death or serious injury. Before making connections to the serial port or NiCad recharger jack in an explosive atmosphere, check the Communicator nameplate and the manual supplied with the Communicator for approvals. Figure 2-2 illustrates typical wiring connections between the HART Communicator and a loop with a Model 340 transmitter or other HART-compatible device on a loop. The Communicator is quickly connected into a transmitter loop.

Minimum value 250 Ohms; maximum value 1100 Ohms. 4. Supply and return barriers shown. Interconnect all cable shields and ground only at the barriers. FIGURE 2-2 HART Communicator Connections to a Transmitter Loop May 1998 2-3 MODEL 275 UNIVERSAL HART COMMUNICATOR UM340-1 A 40" (1 m) cable with a dual banana plug on one end and two mini-grabber plugs on the other is provided. The dual banana plug is inserted into the top of the Communicator; the mini-grabber clips are connected to lugs in the Model 340’s terminal board compartment or to the loop’s current sense resistance, usually at a receiving instrument (see Note below). NOTE The HART protocol requires a network (loop) resistance between 250Ω and 1100Ω to support communications. See Section 4.3.5 to determine resistance value and loop supply voltage. 2.3 CONTROLS OVERVIEW As shown in Figure 2-1, the front of the HART Communicator has five major functional areas: liquid crystal display (LCD), function keys, action keys, alphanumeric keys, and shift keys. The next five sections describe how each of these functional areas is used to enter commands and display data. 2.3.1 Liquid Crystal Display The liquid crystal display (LCD) is an 8-line by 21-character display that provides communication between the user and a connected device. When the HART Communicator is connected to a Model 340 transmitter or other HART-compatible device, the top line of the Online menu displays the model name of the device and its tag. A typical display is shown below: MPCO 340A:PT100 Online 1->Loop Override 2 Calibrate/Test 3 Configure Xmtr çz HELP |SAVE The bottom line of each menu is reserved for dynamic labels for the software-defined function keys, F1-F4, which are found directly below the display. More information on software-defined function keys is given in the next section. 2.3.2 Software-Defined Function Keys The four software-defined function keys (softkeys), located below the LCD and marked F1 through F4, are used to perform software functions as indicated by the dynamic labels. Pressing the function key immediately beneath a label activates the displayed function. The label appearing above a function key indicates the function of that key for the current menu. For example, in menus providing access to on-line help, the HELP label appears above the F1 key. In menus providing access to the Online menu, the HOME label appears above the F3 key. Table 2-1 lists these labels and describes what happens when each function key is pressed. 2-4 May 1998 UM340-1 MODEL 275 UNIVERSAL HART COMMUNICATOR TABLE 2-1 Function Keys with Their Labels and Actions Performed F1 F2 F3 F4 HELP ON/OFF ABORT OK Access on-line help activate or deactivate a bit-enumerated binary variable terminate current task Acknowledge information on the LCD RETRY DEL ESC ENTER try to reestablish communication delete current character or Quick Access Key menu item leave a value unchanged accept user-entered data EXIT SEND QUIT EXIT leave the current menu send configuration data to device terminate session because of a communication error leave the current menu YES PGUP PGDN NO Answer to yes/no question move up one help screen move down one help screen answer to yes/no question ALL PREV NEXT ONE Include current Quick Access Key item on Quick Access Key menu for all devices go to previous message in a list of messages go to next message in a list of messages include Quick Access Key item for one device NEXT SAVE HOME go to the next variable in off-line edit save information to Communicator go the top menu in the device description FILTR MARK BACK Open customization menu to sort configurations toggle marked variable in configuration to be sent to a field device go back to the menu from which HOME was pressed XPAND EDIT opens detailed configuration information edit a variable value CMPRS ADD closes detailed configuration information add current item to Quick Access Key menu May 1998 2-5 MODEL 275 UNIVERSAL HART COMMUNICATOR UM340-1 2.3.3 Action Keys Directly beneath the LCD and software-defined function keys are six blue, white, and black action keys. Each has a specific function as described below: I O ON/OFF KEY – Use to power-up the Communicator. When the Communicator is turned on, it automatically searches for a HART-compatible device on the 4-20 mA loop. If no device is found, the Communicator displays the Main menu: HART Communicator 1->Offline 2 Online 3 Frequency device 4 Utility If a HART-compatible device is found, the Communicator displays the Online menu: MPCO 340A:PT100 Online 1->Loop Override 2 Calibrate/Test 3 Configure Xmtr çz HELP |SAVE UP ARROW KEY – Use to move the cursor up through a menu or list of options or to scroll through lists of available characters when editing fields that accept both alpha and numeric data. DOWN ARROW KEY – Use to move the cursor through a menu or a list of options or to scroll through lists of available characters when editing fields that accept alpha and numeric data. LEFT ARROW/PREVIOUS MENU KEY – Use to move the cursor to the left or back to the previous menu. RIGHT ARROW/SELECT KEY – Use to move the cursor to the right or to select a menu option. QUICK ACCESS KEY (HOT KEY) – When the Communicator is on and connected to a HART-compatible device, pressing the Quick Access Key instantly displays the Quick Access Key menu of user-defined options. When the Communicator is off and the Quick Access Key is pressed, the Communicator automatically powers-up and displays the Quick Access Key menu. See Section 2.6 for more information on using the Quick Access Key. 2-6 May 1998 UM340-1 MODEL 275 UNIVERSAL HART COMMUNICATOR IMPORTANT When performing certain operations, the message “OFF KEY DISABLED” indicates that the Communicator cannot be turned off. This feature helps prevent accidental shutoff of the Communicator while the output of a device is fixed or a device variable is being edited. 2.3.4 Alphanumeric and Shift Keys The alphanumeric keys perform two functions: (1) rapid selection of menu options and (2) data entry. The shift keys located below the alphanumeric keys on the keypad are used during data entry to select from among the characters available above each number. 2.3.4.1 Rapid Selection of Menu Options From any menu, use the keypad to select available options in two ways. First, use the UP or DOWN arrow keys, followed by the RIGHT ARROW/SELECT key, to access available options displayed on the LCD. As an alternative, use the rapid select feature. Simply press the number on the alphanumeric keypad that corresponds to the desired menu option. For example, to quickly access the Utility menu from the Main menu, simply press “4” on the keypad. 2.3.4.2 Data Entry Some menus require data entry. Use the alphanumeric and shift keys to enter all alphanumeric information into the HART Communicator. Pressing an alphanumeric key alone while editing causes the large character in the center of the key (number 0-9, decimal point, or dash) to be entered. Pressing and releasing a shift key activates shift and causes the appropriate arrow icon (ã, á, or ä) to appear in the upper right-hand corner of the LCD. When shift is activated, the indicated alpha characters or symbols are entered when the keypad is used. Example To enter a number, such as “7,” simply press the number key. To enter one of the small characters appearing above the large numeral (i.e., a letter, space, or mathematical symbol), first press and release the corresponding shift key at the bottom of the keypad, then press the desired alphanumeric key. To enter the letter “E,” press and release the middle shift key, then press the number “2” key. To deactivate a shift key without entering a letter, space, or mathematical symbol, simply press that shift key again. May 1998 2-7 MODEL 275 UNIVERSAL HART COMMUNICATOR UM340-1 2.4 GETTING TO KNOW THE COMMUNICATOR The HART Communicator operates in either of two modes: on-line or off-line. Off-line operation is used to create or edit a configuration that can then be downloaded to a HART device, such as the Model 340. Online operation is used to download a configuration to a HART device, upload a configuration, edit HART device operating parameters, and monitor process values. For off-line operation, the Communicator need not be connected to a HART device. On-line operation requires a connection to a HART device. The menu that appears first when the Communicator is turned on depends on the mode. When the Communicator is powered-up in off-line mode, the first menu displayed is the Main menu. When the Communicator is powered-up in on-line mode, the first menu displayed is the Online menu. To work offline when connected to the loop, access the Main menu from the Online menu by pressing the LEFT ARROW/PREVIOUS MENU key. 2.4.1 Display Icons Several different symbols (icons) appear on the LCD to show the state of the Communicator and provide visible response to actions of the user. Figure 2-3 shows the display icons and how they relate to keypad functions. HART Communication ( indicates connected device is configured in the burst mode) HARTCommunicator Access Additional Menu Items Device Info 2 Dev Type 3 Dev ID 4 Tag 5 MM/DD/YY 6 Write Protect Low Battery 0 10/10/10 Yes Access Previous Menu X03034S0 FIGURE 2-3 Communicator Display Icons 2.4.2 Menu Structure The HART Communicator uses a hierarchical menu structure. That is, high-level menus are accessed first, and they provide access to lower-level menus. This structure groups related functions together and minimizes the number of options displayed at once. 2-8 May 1998 UM340-1 MODEL 275 UNIVERSAL HART COMMUNICATOR To learn how the menu structure works, perform the following actions: 1. With the Communicator off-line (not attached to any devices), press the ON/OFF key to turn the Communicator on. It displays the Main menu, with the cursor (->) positioned at “1 Offline.” 2. Access the Utility menu by pressing the DOWN arrow key three times, then pressing the RIGHT ARROW/SELECT key. The display changes to show the Utility menu. 3. Access the Configure Communicator menu from the Utility menu by pressing the RIGHT ARROW/SELECT key. The display changes to show the Configure Communicator menu. 4. Access the Contrast menu by pressing the DOWN arrow once, then pressing the RIGHT ARROW/SELECT key. The display shows a message explaining how to adjust the LCD contrast. 5. Press ESC (F3) to return to the Configure Communicator menu. 6. Press the LEFT ARROW/PREVIOUS MENU key two times to return to the Main menu. 7. Press the ON/OFF key to turn the Communicator off. 2.4.3 Reviewing Installed Devices For the HART Communicator to recognize a HART-compatible device, it must have a description for that device installed. The HART Communicator is supplied from the factory with descriptions for Model 340 Transmitters and other HART-compatible devices from leading manufacturers. In addition, it contains a generic device description, which allows limited access to most HART devices when no device description for that specific device exists in the Communicator. To review the currently installed devices on the Communicator, use the following steps: 1. Turn on the Communicator (off-line) to display the Main Menu. 2. From the Main menu, press “4” on the keypad for quick access to the Utility Menu. 3. From the Utility menu, press “5” on the keypad to access the simulation mode. The LCD shows the Manufacturer menu, which contains a list of manufacturers whose device descriptions are installed in the Communicator. 4. Press the DOWN arrow until Moore Products appears. Press the RIGHT ARROW/SELECT key to reveal the Model menu, which lists the Moore Products Co. devices currently installed in the Communicator (see Table 2-2). 5.

Topics include: equipment delivery and handling, environmental and installation considerations, and mechanical and electrical installation. IMPORTANT Before installing or servicing a transmitter: • Read the information on the nameplate and ensure that the correct model is at hand and that the correct procedures are followed. See Section 9.1, Model Designations for an explanation of the model designation alphanumeric sequence shown on the nameplate. • The installation must conform to the National Electrical Code and all other applicable construction and electrical codes. Refer to the installation drawings in Appendix B when locating a transmitter in a hazardous area. • Refer to Section 9.3.6 Special Conditions for Safe Use for approval agency requirements that affect installation and use of the instrument. Refer to Appendix E for CENELEC for EEx d installations. 4.1 EQUIPMENT DELIVERY AND HANDLING 4.1.1 Factory Shipment Prior to shipment, a transmitter is fully tested and inspected to ensure proper operation. It is then packaged for shipment. Most accessories are shipped separately. Everything in a box is indicated on the box label. 4.1.2 Receipt of Shipment Each carton should be inspected at the time of delivery for possible external damage. Any visible damage should be recorded immediately on the carrier’s copy of the delivery slip. Each carton should be unpacked carefully and its contents checked against the enclosed packing list. At the same time, each item should be inspected for any hidden damage that may or may not have been accompanied by exterior carton damage. If it is found that some items have been damaged or are missing, notify Moore Products Co. immediately and provide full details. In addition, damage must be reported to the carrier with a request for their on-site inspection of the damaged item and its shipping carton. 4.1.3 Storage If a transmitter is to be stored for a period prior to installation, review the environmental specifications in Section 9.3. 4.2 ENVIRONMENTAL CONSIDERATIONS Many industrial processes create severe environmental conditions. The conditions at each transmitter location must be within the specifications stated in Section 9.3. May 1998 4-1 INSTALLATION UM340-1 Although the transmitter is designed to perform in harsh conditions, it is prudent to choose a location that minimizes the effects of heat, vibration, shock, and electrical interference. CAUTION Exceeding the specified operating temperature limits can adversely affect performance and may damage the instrument. 4.3 INSTALLATION CONSIDERATIONS Sections 4.3.1 and 4.3.2 outline basic considerations needed to achieve a successful mechanical/ electrical installation. The remaining sections then provide detailed pre-installation information. 4.3.1 Mechanical • XTC transmitters are suitable for, but not limited to: – Flow Measurement – Gauge Pressure Measurement – Level Measurement – Draft Pressure Measurement – Absolute Pressure Measurement – – High Differential Pressure Measurement Hydrostatic Tank Gauging Measurement • Determine if an optional Smart Display for local monitoring of transmitter output is required. Refer to Section 9.1 for model designation or 9.2 for accessory part numbers. • Determine physical mounting of the transmitter. Consider: – Optional brackets for pipe mounting or surface mounting – Pipe or tank wall thickness, diameter, rigidity, and freedom from vibration – Clearance for installation and maintenance and for reading the optional Smart Display – Need to rotate Smart Display for viewing ease Refer to Figures 9-1, 9-2, and 4-14 for transmitter dimensions and the figures in Sections 4.4 and 4.5 for typical mechanical installations. Refer to Section 9.3 for mechanical and environmental specifications. • Determine if an explosion-proof or intrinsically safe installation is required. Refer to transmitter nameplate for electrical classifications and to Sections 4.8 and 9.3. An intrinsically safe installation requires user-supplied intrinsic safety barriers that must be installed in accordance with barrier manufacturer’s instructions for the specific barriers used. Transmitter certification is based on the “entity” concept in which the user selects barriers that permit the system to meet the entity parameters. 4-2 May 1998 UM340-1 INSTALLATION • Models 340 D, A, and G – Consider pressure piping recommendations. Refer to Section 4.3.3. • Determine conduit routing. Refer to Section 4.6.2. • Consider bolting the transmitter to a two- or three-valve manifold. Model 340D – Install a three-valve manifold because this device provides both an equalizing valve and high and low pressure block valves. Use the equalizing valve to equalize pressure between inputs before calibrating or servicing the transmitter. Use block valves to isolate the transmitter from the process for servicing or removal. Models 340A and G – Install a two-valve manifold for similar purposes to those listed above. Model 340F – Consider using flushing rings to flush and clean the process connection without removing the flange. Prepare installation site drawings showing the following: • Location of the Master Device (e.g., HART Communicator or controller) • Location and identification of each transmitter • Routing plan of signal cable(s) • Location of any signal cable junctions for connecting the HART Communicator 4.3.2 Electrical • Determine transmitter operating mode (analog or digital) and type of Network needed; refer to Section 4.3.4. • Determine minimum power supply requirements. Refer to Section 4.3.5. • Select twinaxial cable type and determine maximum cable length. Refer to Section 4.3.6. • Determine the need for network junctions. Refer to Section 4.3.7. • Intrinsically Safe installations will need barriers. Refer to Section 4.3.8. • Consider the effect of connecting additional equipment (e.g., recorder, loop powered display) to the network. Refer to Section 4.3.9. • Read Section 4.3.10 for shielding and grounding recommendations. May 1998 4-3 INSTALLATION UM340-1 4.3.3 Impulse Piping for Models 340D, A, and G Impulse piping is the piping to be connected to the transmitter’s process connection(s). For suggested flow and level measurement piping arrangements, refer to: • Model 340D - Figures 4-1 and 4-2 • Model 340A or G - Figures 4-3 and 4-4 • Model 340F - Figure 4-5 Note the following when planning and installing piping. • Install impulse piping in accordance with ANSI Code B31.1.0. • Make impulse piping length as short as possible to reduce frictional loss and temperature-induced pressure variations. However, when using impulse lines on a high temperature process, locate the transmitter far enough away from the heat source to keep it within temperature specifications [28°C (50ºF) per foot cooling to a normal ambient is assumed for uninsulated impulse lines]. • For lines between the process and transmitter, use impulse piping of 3/8" OD or larger to avoid friction effects (causes lagging) and blockage. • Use the least number of fittings and valves possible to minimize leakage problems. TFE/PTFE tape is the recommended thread sealant for process connections at the transmitter. • Valves used in pressure service should be either globe or gate type. Valves used in gas service should be of a type that does not permit condensate to build up behind the valve. • Install sediment chambers with drain valves to collect solids suspended in process liquids or moisture carried with non-condensing gases. • Install air chambers with vent valves at high point in piping to vent gas entrained in process liquid. • Remote diaphragm seals can be used to keep corrosive liquid or gas from the transmitter pressure inlets and isolation diaphragm (see PI34-6 for details). • Alternatively, use sealing fluid to isolate the process from the transmitter. Sealing fluid must be of greater density than process fluid and non-miscible. • For transmitters located above the process, slope piping from the transmitter at least 1 inch/foot (83 mm/M) down toward process. For transmitters below the process, slope piping at least 1 inch/foot (83 mm/M) up to process. • Protect pressure lines (by shielding if necessary) from objects or equipment that may bend or kink the line causing fluid flow restriction. • Protect the pressure lines from extreme temperature ranges. Lines should be protected from freezing by installing a heat trace. • A three-valve manifold should be used with a Model 340D. A two-valve manifold can be used with a Model 340A or G transmitter to permit servicing and zero checks. 4-4 May 1998 UM340-1 INSTALLATION Low Pressure Side Low Pressure Side Flow High Pressure Side High Pressure Side Model 340D Model 340D 3-Valve Manifold Flow 3-Valve Manifold Horizontal Main Line Flow Transmitter Below Orifice - Preferred for Liquids and Steam Horizontal Main Line Flow Transmitter Above Orifice - Preferred for Gas Flow High Pressure Side Low Pressure Side Low Pressure Side Flow Flow Model 340D High Pressure Side 3-Valve Manifold Model 340D 3-Valve Manifold Vertical Main Line Flow Transmitter Below Orifice Vertical Main Line Flow Transmitter Above Orifice X03038S0 FIGURE 4-1 Differential Flow Measurement Piping for Gas and Liquid May 1998 4-5 INSTALLATION UM340-1 Fill Connection LP Shut-Off Valve LP Shut-Off Valve Max.

FIGURE 4-8 Wiring for Controller Operation May 1998 4-13 INSTALLATION UM340-1 4.3.4.2 Digital Mode When a transmitter is configured for digital mode operation, the following statements apply. • The process variable is transmitted digitally. The analog output of each transmitter is “parked” at 4 mA. • Employs a Multi-Drop network. See Figure 4-9. • The optional Smart Display can be used for local indication of transmitter output. The number of allowable network elements is: – – Primary and Secondary Masters - 1 each Transmitters - 1 to 15 • The HART communication source can be a Primary or Secondary Master. A Primary Master can be used for data acquisition, maintenance, or control purposes. A Secondary Master, the HART Communicator, for example, may be used for configuration, diagnostics, and reporting current process variable. • Place the transmitter in the digital mode by assigning it a polling address (1 to 15) when configuring the Transmitter ID block with the HART Communicator (see Section 6). • Each transmitter must have a unique address. 4.3.5 Power Supply Requirements A power supply is needed to power the transmitter(s). The power supply can be: • A separate stand-alone supply capable of powering several transmitters. It can be mounted in a control room or in the field. Follow the power supply manufacturer’s recommendations with regard to mounting and environmental considerations. • Located in a controller (such as a Primary Master) or other station able to safely provide additional operating current and meet the power supply specifications of Section 9.3. The total Network Resistance is the sum of the Current Sense Resistance, end-to-end Barrier Resistance (if used), wire resistance, and any other resistances in the loop.

X03046S1 FIGURE 4-9 Multi-Drop Network (Digital Mode) May 1998 4-15 INSTALLATION UM340-1 4.3.5.1 Point-to-Point Network The graph in Section 4.3.5 defines an analog mode transmitter’s operating region for the allowable ranges of supply voltage and network resistance. Perform the following calculations to ensure that the power supply output voltage permits the transmitter to remain within the indicated operating range. 1. Calculate the minimum power supply output voltage. The minimum network power supply voltage requirement is a function of Network Resistance and full scale current (20 mA), and is calculated by the following formula: Minimum Power Supply Output Voltage = 10 volts + (0.02 × Network Resistance in ohms) Power supply output voltage must be greater than the calculated value. The minimum voltage across the input terminals of a transmitter is 10 volts. 2. Calculate the maximum power supply output voltage. The maximum network power supply voltage is a function of Network Resistance and zero scale current (4 mA), and is calculated by the following formula: Maximum Power Supply Output Voltage = 42 volts + (0.004 × Network Resistance in ohms) Power supply output voltage must be less than the calculated value. The maximum voltage permitted across the input terminals of a transmitter is 42 volts. 4.3.5.2 Multi-Drop Network Perform the following simple calculations to ensure that the power supply output voltage permits the Transmitter to remain within its operating range. 1. Calculate the minimum power supply output voltage. Minimum network power supply voltage is a function of Network Resistance and the total current draw of all transmitters in the network, and is calculated by the following formula: Minimum Supply Output Voltage = 10 volts + [(0.004 × number of transmitters on Network) × (Network Resistance)] Power supply output voltage must be greater than the calculated value. The minimum voltage across the input terminals of a transmitter is 10 volts. 2. Calculate the maximum power supply output voltage. Maximum network power supply voltage is a function of Network Resistance and total current draw of all the transmitters in the network, and is calculated by the following formula: Maximum Supply Output Voltage = 42 volts + [(0.004 × number of transmitters on Network) x (Network Resistance)] Power supply output voltage must be less than the calculated value. The maximum voltage permitted across the input terminals of a transmitter is 42 volts. The maximum number of transmitters that can be connected to a Multi-Drop Network is 15. Each transmitter is “parked” in a low current draw mode (4 mA) to conserve power. Ensure that the network power supply is capable of sourcing the total current consumed by the number of transmitters on the network. 4-16 May 1998 UM340-1 INSTALLATION 4.3.6 Cable Capacitance and Maximum Length A cable length calculation is necessary when HART communication is to be employed. Cable capacitance directly affects maximum network length. 4.3.6.1 Cable Capacitance Cable type, conductor size, and recommended cable model numbers are stated in Section 9.3.3 Two-Wire Cable. Cable capacitance is a parameter used in the calculation of the maximum length of cable that can be used to construct the network. The lower the cable capacitance the longer the network can be. Manufacturers typically list two capacitance values for an instrumentation cable: 1. Capacitance between the two conductors. 2. Capacitance between one conductor and the other conductor(s) connected to shield. This capacitance is the worst case value and is to be used in the cable length formula. 4.3.6.2 Maximum Cable Length Calculation The maximum permissible single-pair cable length is 10,000 feet (3000 meters) or less as determined by the following formula: 65,000,000 Cf + 10,000 L= – R×C – C Formula Definitions: L: The maximum total length of cable permitted to construct the network. L = feet when C is in pF/ft; L = meters when C is in pF/meter. R: The Network Resistance which is the ohmic sum of the current sense resistance and barrier resistance (both return and supply), if any, in the network and the resistance of the wire. C: Cable capacitance per unit length between one conductor and the other conductor connected to the shield. C may be in pF/ft or pF/meter. Cf: Total input terminal capacitance of field instruments; the Primary Master is excluded. Cf is given by the following formula: Cf = (sum of all Cn values) x (5000) Where Cn is an integer (e.g., 1, 2, 3) corresponding to the input terminal capacitance of a Field Instrument. Cn values are determined as follows: May 1998 4-17 INSTALLATION FIELD INSTRUMENT CAPACITANCE UM340-1 Cn VALUE Less than 5000 pF 1 5000 pF to less than 10000 pF 2 10000 pF to less than 15000 pF 3 15000 pF to less than 20000 pF 4 20000 pF to less than 25000 pF 5 For field instruments without Cn values, use Cn = 1 Example Calculation: Assume a network consists of two field instruments (both Cn = 1). Let R = 250Ω, C = 40 pF/ft, Cf = (1 + 1) x 5000 = 10,000 65,000,000 10,000 + 10,000 Then L = ––––––––– – ––––––––––––– = 6000 feet (1800 meters) (250)(40) 40 4.3.7 Network Junctions A network junction is shown in Figure 4-8. It is a wiring junction installed at a convenient point in the loop to facilitate wiring, testing, and troubleshooting. Typically the junction is a conventional terminal block mounted on a panel with a protective cover, cabinet, or junction box to enclose and protect wiring terminals. Multiple junctions can be installed to provide field access terminals for the connection of a HART Communicator. Note the following: • Network with barriers – Locate a junction anywhere along the network in the non-hazardous area. • Network without barriers – A junction may be located anywhere along the network between the power supply and transmitter. • A junction should be a simple electrical series connection containing NO repeaters or other devices (active or passive) that can degrade HART communications. 4-18 May 1998 UM340-1 INSTALLATION 4.3.8 Safety Barriers Installed safety barriers must comply with the following: • Locate intrinsic safety barriers between the system power supply (e.g., Primary Master, if used) residing in the non-hazardous area and the transmitter(s) in the hazardous area. • Combined or separate supply and return barriers may be used. • For an intrinsically safe application, the DC voltage applied to the safe side of the barrier must be 0.6 Vdc less than the rated barrier working voltage. • An active supply barrier must be operated within its specified input working voltage. • Barrier shunt impedance to ground to the HART range of frequencies (500 Hz to 2500 Hz) shall not be less than 5000Ω. • Barrier end-to-end resistance, stated by the manufacturer, is used in calculating the maximum Network cable length and minimum and maximum network voltages. • The barrier shall be installed and wired in accordance with the manufacturers instructions. • Refer to Appendix B for a list of barriers tested for use with typical HART Primary Masters. 4.3.9 Connection of Miscellaneous Hardware Miscellaneous non-signaling hardware (e.g., recorders, current meters) may be connected to a Point-toPoint network in accordance with the following list. IMPORTANT No non-signaling hardware (meters or measuring devices) may be connected to a Multi-Drop network since the transmitters, in this mode, do not output an analog process variable. • Miscellaneous hardware may be series or parallel connected to the network according to its function. • Miscellaneous hardware must be passive two-terminal devices. • Miscellaneous hardware may not generate any type of noise or signals, other than noise that is inherent in resistive components. • Individual miscellaneous hardware must meet the following requirements: – Capacitance to ground ........................ 50 pF maximum – Resistance to ground............................1 MΩ minimum – Impedance if series connected ................ Less than 10Ω – Impedance if parallel connected........Greater than 50kΩ May 1998 4-19 INSTALLATION UM340-1 The maximum number of miscellaneous devices per network is 16. The combined electrical characteristics may not exceed the following: – Maximum capacitance to ground ...................... 800 pF – Minimum resistance to ground ..........................62.5kΩ – Maximum series impedance .................................160Ω – Minimum parallel impedance .............................3125Ω 4.3.10 Shielding and Grounding GROUNDING Ground the transmitter’s enclosure housing through a 16 AWG (or larger) copper wire to a low resistance ground, such as a nearby metal cold water pipe. A screw is provided in the side of the housing for this purpose. The ground wire should be installed even though the housing is often grounded through the electrical conduit or, in some transmitter models, through the process connections and piping. SHIELDING Shielded loop cable is recommended. The preferred method of grounding that shield is shown in Figures 4-6 through 4-9. Ground the cable shield at one point. Multiple grounds can cause signal error and poor HART performance. The location of the ground connection is often determined by the installation environment (hazardous or non-hazardous) or by the requirements of a regulating agency. The following grounding practices are field proven and will reduce magnetically coupled interference. Select the appropriate option from the three bulleted items below for the installation at hand. • Hazardous location - ground the shield(s) only at the barrier(s) or as recommended on the appropriate control (installation) drawing and by the certifying agency. • Non-hazardous location - ground the shield at the network power supply. • 4-20 • Ground the cable shield to the power supply ground terminal. Do not connect the cable shield at the transmitter. • If a network junction box is used, splice the input and output cable shields and isolate them from ground. Non-hazardous location - ground the shield at the Transmitter • Ground the cable shield at the ground screw inside the transmitter’s signal terminal compartment. • Power supply (+) and (-) connections must be floated. • If a network junction box is used, splice input and output shields and isolate them from ground.

Transmitter process connections are on 2.13-inch (54 mm) centers to allow direct mounting (bolting) to a manifold with the same spacing. Each transmitter process connection has two tapped 7/16-20 mounting holes and a 1/4 NPT tapped pressure inlet. Process orifice flanges with standard 2.13-inch spacing permit a transmitter and two- or three-valve manifold combination to be direct mounted. Nipple Mount for Liquid Service Orifice Flanges Low Pressure Side Flow High Pressure Side 3-Valve Manifold Model 340D X03054S0 The procedure for mounting a transmitter to a two- or three-valve manifold, and the manifold to the orifice flanges, is covered by the installation instructions supplied by the manifold manufacturer. The following is a guide and may need to be modified for some installations. TFE/PTFE tape is the recommended thread sealant for process connections at the transmitter. 1. If installed, remove process connection blocks from the transmitter’s end caps (process manifold). 2. Press supplied O-ring seals into the grooves in the face of the two- or three-valve manifold and bolt the transmitter end caps to the transmitter side of the two- or three-valve manifold. 3. Thread ½" nipples of 3 inches (or less) length into the high- and low-pressure ports of the orifice flanges. Thread sealant must be used. 4. Thread the process connection blocks directly onto the nipples. Thread sealant must be used. The ½ NPT tapped hole in a process connection block is off center to accommodate 2-inch or 2.25-inch centers (Figure 9-1). For 2.13" pipe centers, the tapped holes should be offset to the right side. 5. Place the supplied TFE/PTFE gaskets on the connection blocks and bolt them to the manifold. 6. Reposition the optional Smart Display as necessary. Refer to Section 4.6.1. 4-28 May 1998 UM340-1 INSTALLATION 4.5 MECHANICAL INSTALLATION, MODEL 340F The Model 340F Transmitter can be flange mounted directly to the point of measurement on a vessel to provide a liquid level measurement. The flange-mounted diaphragm is factory assembled to the highpressure side of the transmitter. Figure 4-14 shows a typical Model 340F in an ANSI and metric flange. Table 4-2 includes the following mounting information: • Flange thickness • Flange diameter and pressure rating • Number of flange mounting holes • Flange mounting hole diameter • Flange bolt circle diameter Refer to Figure 4-14 and Table 4-2 when performing the following procedure: 1. Determine needed bolt length. The user must supply mounting bolts, nuts, and washers. Bolt length is determined by the combined thickness of the flange mounted on the vessel and the transmitter’s flange. 2. As necessary, loosen the enclosure rotation set screw and rotate the enclosure for clearance and best viewing of the optional Smart Display. 3. Bolt the transmitter’s flange to the vessel’s flange.

May 1998 6-15 ON-LINE OPERATION UM340-1 6.2 LOCAL TRANSMITTER OPERATION The Model 340 has three built-in magnetic switches for local operation. They are located on the electronics module and are actuated through the wall of the transmitter enclosure using the Moore Products Co. magnetic screwdriver supplied with each unit. P/N 20027-84 X02810S0 MOORE PRODUCTS CO. Straight-Slot Tip Magnetic End IMPORTANT Use only the Moore magnetic screwdriver to actuate the magnetic switches. Other magnets can cause inconsistent behavior of one or more switches. The three switch targets are labeled Z (zero), FS (fullscale), and D (damping). Although pushbuttons are not involved, use of these switches is often called “pushbutton mode.” Local functions that can be performed with the magnetic switches are described below. 6.2.1 Smart Display Functionality The optional Smart Display can display the measured variable (MV), process variable (PV), valve (V), setpoint (SP) in PV or MV units, and the output of the totalizer (TOTAL). See Figure 1-6. The PV and MV units appearing on the Smart Display are chosen during configuration of the Operator Display function block (see Section 6.1.1.4) from the following options: • % range – show values as percent of full span (%) • PV units – show values in the units chosen for the process variable (ENG) • MV units – show values in the units chosen for the measured variable (none) • %, MV, and PV – show values in all three types of units The units displayed during transmitter operation depend on (1) the local units option chosen during configuration of the Operator Display block, (2) whether the Controller block is ON or OFF, and (3) whether the Totalizer display is ENABLED or DISABLED. Possibilities are as follows: Local Display Code Controller (from Controller block) Totalizer Display (from Totalizer Block) Variables Available on Local Display MV Off Off MV MV Off On MV, Total MV On Off P in MV units, SP in MV units, V in % MV On On P in MV units, SP in MV units, V in %, Total PV Off Off PV PV Off On PV, Total PV On Off P in PV units, SP in PV units, V in % 6-16 May 1998 UM340-1 ON-LINE OPERATION Local Display Code Controller (from Controller block) Totalizer Display (from Totalizer Block) Variables Available on Local Display PV On On P in PV units, SP in PV units, V in %, Total % Off Off % % Off On %, Total % On Off P in %, SP in %, V in % % On On P in %, SP in %, V in %, Total MV/PV/% Off Off MV, PV, % MV/PV/% Off On MV, PV, %, Total MV/PV/% On Off P in MV units, P in PV units, PV in %, SP in MV units, SP in PV units, SP in %, V in % MV/PV/% On On P in MV units, P in PV units, PV in %, SP in MV units, SP in PV units, SP in %, V in %, Total Total Only Off Off Total Total Only Off On Total Total Only On Off Total Total Only On On Total The valve is always displayed on the Smart Display as a percentage of controller output and the “V” and “%” annunciators are lit. The setpoint is displayed in the same units as the process variable, and the “SP” and “ENG,” or “%,” or (none) annunciators are lit. If the applied pressure is outside the configured range, the display flashes. 6.2.2 Toggling the Display Manually While conducting testing or for other reasons it may be necessary to change the functioning of the Smart Display. Simply touch the magnetic end of the magnetic screwdriver momentarily to one of the targets to perform the following: Z - Halts autotoggling of display if autotoggle is “on.” Touch this target again to resume autotoggling. If left alone, the transmitter will time out and resume autotoggling automatically after 5 minutes. FS - Manually toggle variables on the display if more than one variable has been configured for display (e.g., Local Display Code = %/MV/PV). D - No function May 1998 6-17 ON-LINE OPERATION UM340-1 6.3 LOCAL TRANSMITTER CONFIGURATION (CONTROLLER OFF) The local configuration changes described below apply to transmitters with the controller turned off. Local functions for a transmitter-controller are described in Section 6.4. 6.3.1 Set Local Zero The Z switch is used to set the lower range value (LRV) of the transmitter to equal the applied pressure. The procedure below assumes that the transmitter is field mounted to an operating process. 1. Adjust the process pressure to the zero value. 2. Hold the magnetic end of the screwdriver on the Z switch for 5 seconds or more, then remove the screwdriver from the target. The “PB” annunciator on the optional Smart Display should remain lit after removing the screwdriver; if it does not, repeat this step. If working without a Smart Display, be sure to count seconds properly or hold the screwdriver for 7 or 8 seconds to be sure pushbutton mode is activated. NOTE Pushbutton mode times-out after 1 minute of inactivity. If the PB annunciator goes out, repeat step 2 before proceeding. Pushbutton mode can be deactivated by (1) momentarily holding the magnetic screwdriver on the D switch or (2) waiting 1 minute for the automatic time-out to occur. 3. Set the zero value by momentarily pressing the magnetic end of the screwdriver on the Z switch. The “PB” annunciator on the Smart Display extinguishes, indicating a return to normal mode. The currently applied pressure has now been stored as the LRV (0% range value). NOTE When a new 0% value is set, the transmitter’s 100% value is automatically shifted to maintain the original span, except as follows: • If the process is out of range of the transmitter, then no new zero value is stored. • If the new zero value would shift the fullscale value past the sensor limit, the new fullscale value is automatically set to the appropriate sensor limit (except when this would produce a span that is too small, in which case neither zero nor fullscale values are stored). 4. The zero set is complete. To set a new fullscale, go to the next section. 6.3.2 Set Local Fullscale The FS switch is used to set the upper range value (URV) of the transmitter to equal the applied pressure. The procedure below assumes that the transmitter is field mounted to an operating process. Changing the fullscale value does not change the zero value. 1. Adjust the process pressure to the fullscale value. 2. Hold the magnetic end of the screwdriver on the FS switch for 5 seconds or more, then release the pushbutton. The “PB” annunciator on the Smart Display should remain lit after removing the 6-18 May 1998 UM340-1 ON-LINE OPERATION screwdriver; if it does not, repeat this step. If working without a Smart Display, be sure to count seconds properly or hold the screwdriver for 7 or 8 seconds to be sure pushbutton mode is activated. NOTE Pushbutton mode times-out after 1 minute of inactivity. If the PB annunciator goes out, repeat step 2 before proceeding. Pushbutton mode can be deactivated by (1) momentarily holding the magnetic screwdriver on the D switch or (2) waiting 1 minute for the automatic time-out to occur. 3. Enter the fullscale value by momentarily pressing the magnetic end of the screwdriver on the FS switch. Observe that the “PB” annunciator on the Smart Display extinguishes, indicating a return to normal mode. The currently applied pressure has now been stored as the URV (100% range value). NOTE Changing the fullscale value of the transmitter does not affect the zero value. If the input value is either smaller than the minimum span or larger than the maximum span allowed by the transmitter, then no new fullscale value is stored. 4. The fullscale set is complete. To adjust damping, go to the next section. 6.3.3 Adjust Local Damping Adjusting the damping changes the value of the digital filter’s time constant. The D, Z, and FS switches are used to select one of 10 damping values. The HART Communicator can be used to confirm the damping settings. 1. Hold the magnetic end of the screwdriver on the D switch for 5 seconds or more, then release the pushbutton. The “PB” annunciator on the Smart Display should remain lit after removing the screwdriver; if it does not, repeat this step. If working without a Smart Display, be sure to count seconds properly or hold the screwdriver for 7 or 8 seconds to be sure pushbutton mode is activated. NOTE Pushbutton mode times-out after 1 minute of inactivity. If the PB annunciator goes out, repeat step 1 before proceeding. Pushbutton mode can be deactivated by (1) momentarily holding the magnetic screwdriver on the D switch or (2) waiting 1 minute for the automatic time-out to occur. 2. Set the damping value to 0 seconds by momentarily touching the Z switch with the magnetic end of the screwdriver at least 10 times. This establishes a known starting point: 0 seconds. When a Smart Display is present, it alternately displays “0.00” and “SEC” at this point. May 1998 6-19 ON-LINE OPERATION UM340-1 3. Change to a new damping value by momentarily touching the FS switch “N” times to step to the value nearest the desired damping value (DV, in seconds) as shown below. If the desired damping value is exceeded, lower the damping value by momentarily touching the magnetic screwdriver to the Z switch for each step. N 1 2 3 4 5 6 7 8 9 DV 0.1 0.2 0.5 1 2 5 10 20 30 While setting damping, the Smart Display shows alternately “SEC” for seconds and the new damping value in seconds. Observe that the value is correct. 4. When the desired damping value has been set, momentarily touch the D switch with the magnetic end of the screwdriver. This stores the damping value in the transmitter and returns the transmitter to normal mode. 6.4 LOCAL TRANSMITTER-CONTROLLER CONFIGURATION (CONTROLLER ON) When the controller is on, magnetic switches accessible through the enclosure can be used to perform the following functions: • Transfer control from auto (A) to manual (M) mode or vice versa • Change setpoint • Store setpoint as power-up setpoint (PUSP) • Change valve • Store valve as power-up valve (PUV) The procedures below are performed using a Moore Products Co. magnetic screwdriver and the three switch targets Z (zero), FS (fullscale), and D (damping) located on the upper side of the transmitter enclosure (see Section 6.2). 6.4.1 Local A/M, Setpoint, and Valve Adjustments These procedures assume that the transmitter is field mounted to an operating process and contains an optional Smart Display to show the Auto and Manual control mode and process variable, set point, and valve values. Change A/M Control Mode The active control mode is shown on the Smart Display by a lit “A” (Auto) or “M” (Manual) annunciator. 1. Hold the magnetic screwdriver on the D target for at least 5 seconds. The “PB” annunciator will light and remain lit as long as the switch is activated. 2. When the control mode annunciator changes from “A” to “M” or “M” to “A,” remove the screwdriver to release the switch. The control mode is now changed. 6-20 May 1998 UM340-1 ON-LINE OPERATION Change and Store Setpoint The controller must be in the Auto control mode to change the setpoint. If it is not, change the mode using the preceding procedure. 1. Hold the magnetic screwdriver on the Z switch for at least 5 seconds. When the “SP” and “PB” annunciators are both lit, remove the screwdriver from the switch. The displayed number is the active setpoint value. NOTE If no action is taken within 1 minute, the display reverts to the process value. If that occurs, repeat step 1 before proceeding. 2. To change the setpoint value to a new value: • Touch the magnetic screwdriver repeatedly to the FS switch to increase the setpoint value in 0.01% increments of span or touch the magnetic screwdriver repeatedly to the Z switch to decrease the set point in 0.01% increments of span. • Alternatively, hold the magnetic screwdriver over either switch for more than 1 second. Setpoint value increases or decreases rapidly as long as the switch is held. NOTE The new setpoint is not yet stored as the power up setpoint (PUSP) in the transmitter. If the pushbutton mode is allowed to time out before storage is accomplished (“PB” annunciator goes out), the controller operates with the new setpoint, but will revert to the PUSP in the event of power-down. 3. To store the new setpoint in the transmitter as the PUSP, touch the magnetic screwdriver momentarily to the D switch. The controller stores the setpoint value and returns to normal mode. This completes the setpoint storage procedure. Change and Store Valve Signal The controller must be in Manual control mode to change the valve signal. If it is not, change the mode using the “Change A/M Control Mode” procedure before proceeding. 1. Hold the magnetic screwdriver on the FS switch for at least 5 seconds. When the “V,” “%,” and “PB” annunciators are lit, remove the screwdriver from the switch. The displayed number is the current valve signal in percent. NOTE If no action is taken within 1 minute, the display reverts to the process value. Repeat step 1 before proceeding. Interpreting a valve open/close position depends upon knowing if the final control element is configured as reverse or direct acting. For direct acting, 0% indicates a fully closed valve and 100% indicates a fully opened valve. The opposite is true for reverse acting. May 1998 6-21 ON-LINE OPERATION UM340-1 2. To change the valve to a new value between -10% and 110%: • Touch the magnetic screwdriver repeatedly to the FS switch to increase the percentage in 0.01% increments or touch the magnetic screwdriver repeatedly to the Z switch to decrease the valve signal in 0.01% increments. • Alternatively, hold the magnetic screwdriver over either switch for more than 1 second. Valve signal increases or decreases rapidly as long as the switch is held. NOTE The new valve signal is not yet stored permanently in the transmitter. If the pushbutton mode times-out before storage is accomplished (“PV” annunciator appears and process value is displayed), the controller operates with the new valve signal, but will revert to the original valve signal in the event of power-down or Master Reset. To store the new valve signal in the transmitter, touch the magnetic screwdriver momentarily to the D switch. The controller stores the valve signal and returns to normal mode. This completes the valve signal storage procedure. 6.5 DISABLING THE MAGNETIC SWITCHES The magnetic switches described above may be disabled using a jumper located on the optional Smart Display board (see Figure 4-15). To disable the magnetic switches, move the jumper to the DIS position. If a Smart Display is not installed, then the magnetic switches cannot be disabled. n 6-22 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 7.0 CALIBRATION AND MAINTENANCE This section describes calibration, preventive maintenance, and troubleshooting. The Calibration section contains procedures to calibrate a Model 340 and to eliminate any position-induced zero shift. The Maintenance section has preventive maintenance procedures that are employed to protect the reliability of the transmitter. Should a malfunction occur, procedures in the Troubleshooting section can help minimize downtime. This section also includes transmitter removal and replacement procedures, recommended spare and replacement parts, software compatibility, and return shipment instructions. WARNING In Division 1 areas, where an explosion-proof rating is required, remove power from the transmitter before removing the transmitter’s enclosure cap for access to the electrical terminal compartment. 7.1 CALIBRATION A transmitter is calibrated at the factory and should not require field calibration, except to eliminate any position-induced zero shift. Sections 7.1.2 and 7.1.3 describe field calibration, which is performed using a Model 275 HART Communicator. Transmitter calibration should be checked annually and the procedures in this section performed if the transmitter is found to be out of tolerance. 7.1.1 Equipment Required Prior to performing calibration, obtain the following: • HART Communicator, which has built-in calibration programs • Laboratory grade digital multimeter (DMM) for calibrating the 4 to 20 mA output signal Voltmeter Section Accuracy ±0.01% of reading Resolution 1.0 mV Input impedance 10 MΩ Ammeter Section Accuracy ±0.1% of reading Resolution ±1 µA • • Shunt resistance 15Ω or less 24 Vdc power supply; for bench calibration Resistor 250Ω ±1%, carbon, ¼ watt; for bench calibration Depending on whether bench or field calibration is to be done, make connections as shown in either Figure 7-1 or Figure 7-2.

FIGURE 7-2 Field Test Connections 7-2 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 7.1.2 Zero Trim Model 340 transmitters are calibrated at the factory in a vertical position ( nameplate up). If a transmitter is installed (or will be installed) in another orientation, it may need recalibration to eliminate positioninduced zero shift, depending upon transmitter type and direction of rotation. Maximum zero shift is 1.2 inches H2O (299 Pa). Each time a transmitter is rotated from the orientation in which it was zeroed, there is the possibility of zero shift and the need for re-zeroing. Zero shift can be predicted, as follows: • There is no zero shift with transmitter rotation as long as diaphragm orientation with respect to the earth does not change. For example, in the drawing below, rotating the transmitter 90° either clockwise or counterclockwise from the nameplate-on-top reference orientation will not cause a zero shift because diaphragm orientation with respect to earth has not changed. MOORE MOORE Diaphragm Plane M O O R E M O O R E Diaphragm Plane MOORE MOORE Diaphragm Plane 90° Counterclockwise Rotation • Reference Orientation 90° Clockwise Rotation Maximum zero shift occurs when rotating the transmitter causes diaphragm orientation with respect to the earth to be changed 90°. Diaphragm Plane, Edge View H H H Diaphragm Plane, Edge View 90° Counterclockwise Rotation Reference Orientation Diaphragm Plane, Edge View 90° Clockwise Rotation For example, in the drawing below, rotating the transmitter 90° either clockwise (terminal board end down) or counterclockwise (display end down) from the nameplate-on-top orientation will cause maximum zero shift because the diaphragm orientation changed from vertical to horizontal. May 1998 7-3 MAINTENANCE UM340-1 7.1.2.1 Removing Zero Shift Zero shift is easily removed by performing the following procedure. Prepare by performing the following steps: 1. Mount the transmitter in its final mounting position (orientation). IMPORTANT A bench re-zeroing can be performed provided the transmitter is exactly positioned (oriented) as it will be when installed in the field. However, field re-zeroing is more accurate. 2. Pipe the transmitter and adjust applied pressures. • Model 340D Differential Pressure Transmitter - For best performance, NO pressures, other than atmospheric, should be applied to the transmitter’s process HIGH and LOW input pressure ports unless used in a process that has a constant measurable static pressure. In this case perform this procedure at the operating static pressure. For field mounted differential pressure transmitters with piping connected to the LOW pressure port, the manipulation of piping valves and/or drains may be needed to ensure the appropriate requirement is met. • Model 340A Absolute Pressure Transmitter - To zero the transmitter, a full vacuum must be pulled on the transmitter. A zero off-set will occur with less than a full vacuum. 3. Connect the HART Communicator to the transmitter and apply power. 4. From the Online menu, press “2” on the keypad to access the Calibrate/Test menu. From the Calibrate/Test menu, press “2” to access the Calibrate menu (at right). If the transmitter zero is being calibrated at the bench, be sure the transmitter is positioned exactly as it will be when installed.

The Communicator displays the message “WARN–Loop should be removed from automatic control.” If it is permissible to do this, do so, and press OK (F4). If not, press ABORT (F3) to terminate this procedure. 7. If OK was pressed, the Communicator displays the message “WARN–This will affect sensor calibration.” Press OK (F4) to continue or press ABORT (F3) to terminate this procedure without calibrating the sensor zero. If OK was pressed, the Communicator displays “Apply 0 input to sensor.” Make sure 0 input is being applied to the transmitter, then press OK (F4). 7-4 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 8. The Communicator automatically re-zeros the sensor while displaying the message “Sensor input stabilizing.” It then displays “Sensor zero succeeded” followed by “NOTE–Loop may now be returned to automatic control.” This signifies that the zero has been adjusted correctly. To terminate the procedure, do not change the input and press ABORT (F3). 9. Return the loop to automatic control if necessary, then press OK (F4) to return to the Calibrate menu. This completes the zero trim procedure. 7.1.3 On-Line Zero Adjust In some processes, the zero reference can change, for example, due to uneven changes of product density in the impulse piping. On-line zero adjustment changes the zero reference by a percentage of span while process pressure is applied to the transmitter. The on-line zero adjust also is very useful for zeroing absolute transmitters when a good vacuum pump is not available. 1. Establish communication between the Communicator and transmitter. Refer to Section 3.2 as necessary. 2. From the Online menu, press “2” to display the Calibrate/Test menu. Press “2” to display the Calibrate menu. 3. Press “3” to begin the On-Line Zero process.

The Communicator displays the message “Is PV sufficiently adjusted?” Press “1” for YES to complete on-line zero adjustment, or press “2” for NO. MPCO 340A:PT100 Enter adjustment amount 0.00% 1.0 % HELP |DEL |ABORT |ENTER 6. Pressing NO returns the display to that shown in step 3. Enter a new value for the zero adjust and repeat step 5. 7.1.4 Calibrate Digital-to-Analog Converter (DAC) Calibration of the DAC is not normally required and should be performed only after all other options have been exhausted. Bench calibration is recommended; perform steps 1 through 15. 1. Disconnect the transmitter from the process by performing the steps in Section 7.6. NOTE Removing a transmitter can interrupt power to other transmitters powered from a common power source. Note the effect this can have on process control and operation and, if necessary, follow the proper procedures to shut down the process. When disconnecting the LOOP leads, carefully insulate each lead as it is removed to prevent accidental shorts. May 1998 7-5 MAINTENANCE UM340-1 2. Remove the enclosure cap to access the terminal compartment. 3. Connect the HART Communicator and DMM to the loop as shown in either Figure 7-1 or 7-2. Set the DMM to measure 4-20 mA. 4. Establish communication between the Communicator and transmitter. Refer to Section 3.2 as necessary. Be sure the polling address is set to 0. Refer to Section 6.1.1.5 as necessary. 5. From the Online menu, press “2” to display the Calibrate/Test menu. Press “2” to display the Calibrate menu. 6. Press “2” to begin the Calibrate DAC process.

Disconnect the test equipment, reconnect the jumper on the circuit junction terminals (Figure 7-2), and if necessary return the polling address to the appropriate value. This completes calibration of the transmitter. 7.2 PREVENTIVE MAINTENANCE Preventive maintenance consists of periodic inspection of the transmitter, cleaning the external surface of the transmitter’s enclosure, draining condensate from conduit, and blowing-down or purging impulse piping to keep it free of sediment. Preventive maintenance should be performed at regularly scheduled intervals. 7.2.1 Tool and Equipment Requirements The following tools and equipment are required for servicing: • Set of Phillips and flat-blade screwdrivers. • Set of open-end or box-end wrenches. • Torque wrench (30 ft-lbs), 11/16" socket; used for connection block bolts. • Digital multimeter (DMM); see Section 7.1.1 for specifications 7.2.2 Transmitter Exterior Inspection The frequency of the inspection will depend on the severity of the transmitter’s environment. 1. Inspect the exterior of the transmitter enclosure for accumulated oil, dust, dirt, and especially any corrosive process over-spray. 2. Check that both enclosure caps are fully threaded onto the enclosure, compressing the O-ring between the cap and the enclosure. The O-ring must not be cracked, broken, or otherwise damaged. 3. If an optional Smart Display is installed, inspect the protective viewing glass for cleanliness and damage. Replace a cracked or punctured glass; see Section 7.4 and the Parts List at the back of this Manual. 4. Inspect both enclosure electrical conduit entrances for possible moisture leaks. An unused conduit entrance must be plugged and sealed. Inspect the cable clamps of all watertight cable conduits for loose clamps and deteriorated sealing material. Tighten clamps and reseal as necessary. 5. If a conduit drain is installed, inspect the drain seals for obstructions. 6. If subjected to vibration, inspect all transmitter and mounting bracket hardware for tightness. Tighten loose hardware as necessary. Consider steps to reduce vibration. 7. Inspect process connection blocks for evidence of leakage, both at the impulse pipe connections and at the block interface to the transmitter end caps. If necessary, add sealant to pipe threads, tighten block bolts, and replace block TFE/PTFE seals. May 1998 7-7 MAINTENANCE UM340-1 7.2.3 Transmitter Exterior Cleaning After an exterior inspection of the transmitter, the enclosure can be cleaned with the transmitter operating. 1. Clean the enclosure (except enclosure cap glass) and process manifold with a mild, nonabrasive liquid detergent, and a soft bristle brush, sponge, or cloth. Rinse the weatherproof enclosure with a gentle spraying of water. If the transmitter is subjected to heavy process over-spray, keep the enclosure free of excessive accumulation of process residue. Hot water or air may be used to flush away process residue if the temperature of the cleaning medium does not exceed the operating temperatures of the transmitter as listed in Section 9.3.4 Environmental. 2. Clean enclosure cap glass with a mild, nonabrasive liquid cleaner and a soft, lint-free cloth. 7.2.4 Transmitter Enclosure Interior Inspection WARNING Do not open the transmitter enclosure in an area where there may be risk of explosion or where process or environmental substances can contaminate the transmitter interior. Remove the two enclosure caps periodically to inspect the interior of the transmitter enclosure. No accumulation of dust, dirt, or water (condensate) should be present inside the enclosure. If condensate is present, install a conduit drain (see Figure 4-16). Check that all wire connections are tight. Enclosure threads must be coated with a wet, paste-type, anti-seize compound such as Never-Seez by Emhart Bostik. Inspect the enclosure O-ring for damage. 7.2.5 Transmitter Calibration An annual calibration check should be performed to ensure that the transmitter is within specifications. Refer to Section 7.1 for details. 7.2.6 Impulse Piping To ensure accuracy and continued satisfactory performance, impulse piping must be kept clean and inspected for damage. Sediment or other foreign particles must not clog or collect in piping or the pressure chamber of the process manifold’s process connection blocks. A build up of residue can cause faulty measurement. 1. Inspect impulse piping for loose, bent, or cracked piping. Replace damaged piping. 2. At regular intervals, blow down the piping without passing line fluids containing suspended solids through the process manifold’s process connection blocks. The time interval between blowdowns is determined by the user’s previous experience with such systems or determined by evaluating system performance only after the transmitter has been in operation for a period of time. 7-8 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 7.3 TROUBLESHOOTING This Section provides guidance and procedures to assist in identifying and correcting a malfunctioning transmitter. Section 7.2.1 lists needed tools and equipment. It is recommended that all documentation associated with the transmitter, including piping and loop wiring diagrams and configuration documentation, be obtained and made available to maintenance personnel to facilitate troubleshooting. The most common symptom of a malfunctioning transmitter is incorrect, erratic, or no output. A malfunction can affect the transmitter’s analog output (4-20 mA) or its digital (HART) output. Furthermore, a malfunction can be the result of external forces and not a transmitter fault at all. Section 7.3.1 discusses troubleshooting techniques for the analog output. Section 7.3.2 discusses troubleshooting techniques for the digital output. Section 7.3.3. describes verifying a true transmitter failure should Section 7.3.1 or 7.3.2 not yield desirable results. 7.3.1 Analog Output An analog output problem can appear as one of the following: • No output or very low output. – There is no transmitter output or the output remains low despite changes in the process. • High output. – Transmitter output remains high despite changes in the process. • Erratic output. – Transmitter output varies when process does not. • Sluggish Response – Transmitter seems to respond to process changes very slowly. Often an analog output problem is caused by incorrect transmitter configuration or by something external to the transmitter. The following list shows possible causes and corrective actions for these problems. If reviewing this list and performing applicable corrective actions does not remedy the problem, proceed to Section 7.3.3 Diagnosing a Defective Transmitter. Check Impulse Piping • Check that high and low pressure pipe connections are not reversed. • Check for leaks or blockage. • Check for entrapped gas in liquid lines or for liquid in dry lines. • Check for sediment in transmitter’s process connection blocks. • Check that blocking valves are fully open and that bypass valves are tightly closed. • Check that the density of the fluid in piping is unchanged. Check Loop Power Supply/Wiring • Check loop power supply for blown fuse or tripped circuit breaker. • Check for 10 Vdc minimum across loop +/- terminals in transmitter terminal compartment. • Check power supply output voltage: 15 Vdc minimum; 42 Vdc maximum. • Check polarity of loop wiring at both power supply and transmitter. • Check for loose or broken loop wiring at power supply terminals, supply barriers (if used), junction boxes, and transmitter terminal compartment. • Check for disconnected or broken current sense resistor. • Check for short between shield and loop + wire. • Check for accumulation of moisture in transmitter terminal compartment. • Check loop cable for proper type and length. • Check for electrical interference between the loop cable and any adjacent cables in a cable tray or conduit. May 1998 7-9 MAINTENANCE UM340-1 Check Transmitter Configuration • Check for proper operating mode: analog, address 0; digital, address 1-15. • Check controller status: on or off. • Check characterizer status: on or off. • Check for appropriate transfer function. • Check zero dropout value. Check for a Transmitter Stuck in Override Mode • Re-enter Loop Override from HART Communicator Online menu and properly exit Loop Override Mode. Check for Variable Process Fluid Flow • Install mechanical dampers in process pressure piping. • Select a higher damping value (software filter time constant). Check Primary Element • Check that primary element is correctly installed. • Check element for damage and leaks. • Note any changes in process fluid properties that can affect output. 7.3.2 Digital Output (Communication) A malfunctioning digital output can indicate a defective communication circuit. More commonly, however, these problems are caused by an incorrect or poor installation. It is possible to install a transmitter such that the 4-20 mA signal is correct, yet the digital HART signal is not. The most common symptom of a communication problem is the inability to locate a transmitter on the loop using a HART Master Device, such as the HART Communicator. Typical messages from the HART Communicator include: device disconnected, no device found, or communication error. If communication problems occur, check the following. Refer to the specifications in Section 9 as necessary. • Check that loop resistance is >250Ω, <1100Ω. • Check that electrical noise on loop is not excessive: power supply ripple should not exceed 12 mVp-p. • Check that there are no high inductance devices in the loop (I/P for example). Install a HART communication filter across such a device. • Check that the power supply voltage is high enough for the installed total loop resistance. Refer to Section 4. • Refer to Section 4 and confirm that loop cable length is not excessive. • Check that the HART Master is connected across a load. 7.3.3 Diagnosing a Defective Transmitter Should the above not remedy the problem, the sensor assembly or electronics module may have failed. If the failure permits HART communication, use the HART Communicator to access the transmitter. Microprocessor based self-diagnostic tests continuously examine the sensor assembly and electronics module. Perform the procedure below to access the diagnostic displays and determine if a fault exists. 7-10 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 1. If not already in communication with the suspect transmitter, establish communication (see Section 3.2). 2. Press the Quick Access Key and then press “2” to view the Status Menu. If “FAILSAFE” is displayed the transmitter has entered the failsafe mode. 3. From the Status menu, press “2” to obtain a list of errors. Note which of the error messages in the table below is displayed (multiple errors can be displayed). 4. Confirm that the fault still exists. Press the Quick Access Key again to return to the Online menu. Activate the selftest function by choosing “2” Calibrate/Test, then press “1” to perform a self-test. The transmitter will display a warning message, then perform the test. • If the fault was temporary – possibly as a result of excessive electrical noise or a power line spike – the Communicator will display “Transmitter PASSED transmitter selftest.” If the transmitter passes the selftest, it automatically exits the failsafe mode and resumes normal operation. No further action is required. • If the fault remains, the Communicator displays the message “Transmitter FAILED transmitter selftest.” Repeat the test for additional confirmation. If the transmitter fails again, consult the table below and perform the appropriate corrective action. CODE PROBABLE CAUSE CORRECTIVE ACTION E2 ROM ROM CHECKSUM match failed. Replace electronics module. E3 RAM Microprocessor failed, RAM inoperative. Replace electronics module. E4 EPROM Microprocessor cannot retain configuration or calibration data Reconfigure/recalibrate transmitter. Perform transmitter self-test (step 4). If self-test fails, replace transmitter. E5 TIMER A major cycle interrupted itself. Replace electronics module. E6 SENSOR CHECKSUM match failed. Database Rev. No. does not match software Rev. No. Replace sensor assembly. If a Smart Display is installed on the transmitter it will display the word “FAIL” if any one of these error codes is detected. 7.3.3.1 Additional Troubleshooting for Electronics Module Failure Establish communications between the HART Communicator and transmitter, then check transmitter status. If transmitter status checks OK, exit the Status menu to the Online menu and select Loop Override. Verify the loop by setting the output current to 4, 12, and then 20 mA (read current on Smart Display or ammeter connected to the loop). If selected loop currents are significantly out of tolerance, or loop current cannot be set, replace the electronics module (see Section 7.4.1). If the transmitter passes the loop override test, continue troubleshooting. All Model 340 electronic modules are interchangeable. Try substituting an electronics module from a known good transmitter or from spare parts stock. This may require reconfiguration of the transmitter. May 1998 7-11 MAINTENANCE UM340-1 7.3.3.2 Additional Troubleshooting for a Sensor Assembly The sensor assembly cannot be independently field tested because special pressure generating/measuring equipment, instrumentation, and software are required to confirm operational integrity. The procedures below, consisting of a combination of transmitter self-diagnostics and a known particular symptom, and electronics module substitution, can be used to confirm a sensor assembly problem. First, if “Transmitter FAILED transmitter selftest” is displayed by the HART Communicator, perform the following: 1. Check for obvious physical damage to the sensor assembly or evidence of a loss of fill fluid. 2. Use the Quick Access Key to reach the Status\Errors Menu. If the sensor assembly EEPROM has failed, the message “E6 SENSOR” will display. 3. Transmitter self-diagnostics may not report a failure of the sensor assembly or enhanced mode oscillator (EMO). To identify this type of failure: • From the Errors display, press the LEFT ARROW/PREVIOUS MENU key, followed by “1” on the Communicator keypad to display the MV (item 2 on the menu) and Current (item 6 on the menu). If the EMO or sensor has failed, the values of the MV and I are as follows: – MV is equal to -156.7% of the sensor assembly’s upper range limit as listed in Section 9.3 Specifications. – I 3.84 mA (if URV > LRV) or 21.6 mA (if URV < LRV) Example This example illustrates the MV displayed in the event of failure of transmitter with a Range D sensor assembly (URL +450 inH2O). For a sensor input block configured for one of the following MV units, the corresponding - 156.7% value is listed: MV UNITS URL MV at Failure PSI 16.25 PSI -25.4 PSI inHg 33.7 inHg -52.8 inHg mmHg 842.4 mmHg -1320.0 mmHg inH20 450 inH2O -705 inH2O If defective, the entire sensor assembly must be replaced (see Section 7.4.2). 4. If steps 1 and 2 do not confirm a sensor assembly defect, replace the electronics module with an onhand spare (see Section 7.4.1). If the problem still exists and all other loop elements and wiring have been thoroughly tested, return the transmitter for repair. 7.4 ASSEMBLY REMOVAL AND REPLACEMENT The Smart Display, sensor assembly, electronics module, and terminal board are not user-serviceable. To replace the Smart Display, follow the procedure given in Section 4.6.1. This section describes removal and replacement of the electronics module, sensor assembly, and terminal board. These procedures can be accomplished easily with standard hand tools (see Section 7.2.1 for a list of tools). 7-12 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 7.4.1 Replacing the Electronics Module Replacing the electronics module requires reaching inside the enclosure. Since the sensor assembly cable is short, and space is tight, use care when engaging the keyed connectors. 1. If present, remove the Smart Display as described in Section 4.6.1. 2. Gently pull the electronics module forward (i.e. out of the enclosure) until the sensor assembly cable can be grasped with thumb and forefinger. While holding the cable, pull the electronics module until it disengages from the sensor cable. Refer to Figure 4-15 as necessary. 3. Set the electronics module aside in an electrostatic protective container. Remove the new electronics module from its container. 4. Carefully align the keyed connector on the sensor assembly sensor cable with the jack on the back of the new electronics module. Press the connector into the jack until it is seated fully. 5. Align the tubular extensions on the electronics module cup with the two RFI feed-through pins inside the enclosure. Press in and gently rock the electronics module until it can be pressed in no farther. 6. Install the Smart Display and enclosure cap. Power and configure the transmitter. Use the optional Smart Display or the HART Communicator (Section 5) to ensure that the electronics module is functioning correctly. 7.4.2 Sensor Assembly Removal and Replacement The sensor assembly is not field repairable. It must be replaced if defective. The transmitter must be removed to a workbench to accomplish removal and replacement. Removal 1. If the transmitter is controlling a process, use the proper procedures to shut down the process. Turn off power to the transmitter. 2. Close all appropriate impulse piping valves to isolate the process from the sensor assembly. 3. Disconnect the impulse piping from the sensor’s high and low pressure end caps and separate the pipes from the caps. Drain process fluid from the sensor. 4. Unscrew the rear enclosure cap protecting the terminal board compartment. 5. Tag and disconnect the wires at the terminal board. 6. Disconnect the conduit from the transmitter enclosure and pull the wires free of the enclosure. Replace the rear enclosure cap. 7. Disconnect the transmitter from its mounting bracket and remove it to a workbench. 8. Clamp the end cap portion of the sensor assembly in a bench vise with the transmitter in an upright position. Use wood blocks to protect the end caps from being damaged by the vise. 9. Remove the enclosure cap for access to the electronics module. If an optional Smart Display is installed, remove it as described in Section 4.6.1. Store the Smart Display in a static protective bag. 10. Pull the electronics module just clear of the enclosure and, while holding the sensor assembly sensor cable P1 connector firmly in one hand and the electronics module in the other, pull the two apart. 11. From inside the enclosure compartment, remove the enclosure positioning limit screw (10-32 Allen head) and lockwasher from the sensor assembly’s tube. Retain screw and lockwasher. May 1998 7-13 MAINTENANCE UM340-1 12. Loosen the enclosure rotation set screw on the enclosure stem and gently pull the enclosure away from the tube of the sensor assembly. An O-ring on the sensor assembly’s tube will offer some resistance to pulling. To overcome this resistance, gently rotate the enclosure left and right while pulling. Set the enclosure aside. 13. Clean any process fluid or other contamination from the sensor assembly, including the flange if a 340F model, and repack the entire assembly for return or disposal. NOTE Normally, the sensor assembly is not disassembled, but is replaced in its entirety. A flanged sensor assembly is never field disassembled. If the sensor assembly is disassembled for any reason, replace the TFE/PTFE seals (P/N 1596554) between the capsule and end caps, lubricating them on one side only with Dow Corning No. 4 compound to hold them in place. Install the end caps. Insert the four bolts and tighten in an “X” pattern – lower right, upper left, lower left, upper right. Torque to 30 ft-lbs, then replace the sensor assembly as described below. Replacement 1. Unpack the replacement sensor assembly. 2. Refer to the Parts List exploded view drawing. Reposition the sensor assembly in the bench vise with the sensor’s tube pointing up. Use wood blocks to protect the end caps from damage. 3. Carefully fit the sensor cable through the enclosure neck. Slowly slide the enclosure down on the sensor assembly while rotating the enclosure left and right to overcome the resistance to the tube’s O-ring. 4. When the cable end appears in the enclosure, pull it toward the enclosure opening while continuing to slide the enclosure over the sensor assembly. When a stop inside the enclosure is hit, positioning is correct. 5. Retrieve and install the enclosure positioning limit screw previously removed, a 10-32 Allen head screw and lockwasher. 6. Retrieve the electronics module and connect the sensor cable P1 connector to it. 7. Align the electronics module carefully on the RFI feed-throughs and press it in place. 8. If applicable, install the previously removed Smart Display (see Section 4.6.1). 9. Orient the enclosure and tighten the previously loosened set screw on the enclosure neck. 10. Replace the enclosure cap and tighten until O-ring seats. 11. If desired, perform mounting shift zero shift calibration (see Section 7.1) before field installation of the transmitter. 12. Reinstall transmitter at field site by performing, in reverse, Removal steps 1 to 7. If not already done, perform a zero shift calibration (see Section 7.1). Refer to Section 4 for installation connections. 13. Turn on system power and open valves to restore transmitter to service. Check all connections for leaks. CAUTION Do not exceed the Maximum Overrange ratings when placing the transmitter into service. Properly operate all shut-off and equalizing valves. Ratings are listed in Section 9. 7-14 May 1998 UM340-1 CALIBRATION AND MAINTENANCE 14.

Figure 81 shows the functional block diagram, which consists of the sensor module and the electronics module. The Model 340 Transmitter family consists of four model types: Differential Pressure (340D), Absolute Pressure (340A), Gauge Pressure (340G), and Flange-Mounted Liquid Level (340F). All models use the same interchangeable electronics module. All Model 340 Transmitters can communicate with a HART Communicator or a Primary Master controller using the HART protocol. 8.1 SENSOR ASSEMBLY The sensor assembly is part of the sensor assembly, which includes the process diaphragms and process end caps. The sensor assembly includes an electrically erasable programmable read-only memory (EEPROM) chip, a custom application-specific integrated circuit (ASIC), and a capacitive pressure sensor element. During the characterization process at the factory, all sensor assemblies are subjected to a controlled series of temperature and pressure cycles. Data recorded from the series is used to generate characterization factors, which are stored in the sensor assembly’s EEPROM. The appropriate sensor range limits (Range 1, 2, 3, or 4) also are stored in the EEPROM. Because the characterization data is stored in EEPROM, no calibration is required when replacing a sensor assembly. The capacitive sensor element contains two silicon-based capacitors: a sense capacitor (Cs) whose value changes in response to an applied process pressure, and a reference capacitor (Cr) whose value is independent of pressure. Layers of glass and silicon are combined to form the capacitive sensor element. These layers are anodically bonded to form a seal that is stronger than the glass itself and provides a monolithic structure that is extremely stable and has no measurable hysteresis. The custom ASIC, which is mounted on the header of the capacitive sensor element, contains oscillator, amplifier, and buffer circuitry. The capacitive sensor element is part of the ASIC’s oscillator and forms an enhanced multimode oscillator (EMO), which generates three frequencies based on the capacitive measurements of Cs, Cr, and Cs+Cr. These frequencies are amplified and buffered by the ASIC and presented as CMOS-compatible square wave outputs for processing by the electronics module. 8.2 ELECTRONICS MODULE The electronics module, located in the transmitter’s enclosure, consists of one surface mount electronics board attached to a plastic cup, which holds the board within the enclosure. A separate terminal board, located on the opposite side of the enclosure dividing wall, contains surge and noise filter circuitry and may include an optional transient suppressor board. The electronics module consists of: • Standard Bell 202 modem that uses the frequency shift keying (FSK) technique to communicate via the HART protocol May 1998 8-1 ACCURACY CALCULATIONS Terminal Board UM340-1 Loop + _ 4-20 mA and Bidirectional HART Communication to Control System X03072S0 Electronics Module *R XA = HART received communications from loop *T XA = HART transmission to loop Comm. = Communication Surge and Noise Filter FSK = Frequency Shift Keying 4-20 mA *TXA Electronics Module Loop Supply Voltage *RXA Power Supply Current Limiting Low Voltage DC Low Voltage Power Supply Monitor HART Comm.

The EMO uses the reference capacitor (Cr) and the sum of both capacitors (Cs+r) to generate additional frequencies Fr and Fs+r. One at a time, each of the three frequencies is gated to the EMO ASIC by digital commands from the electronics module. 8.3.2 Frequency to Digital Conversion The first of the three frequencies (Fr, Fs+r, and Fs) generated by the EMO is applied to the ASIC. Two counters in the ASIC count the time and number of cycles for each frequency. This data is stored and a Mode Toggle (MT) command is sent to the EMO to switch to the next frequency. When all three frequencies are stored, the Microcontroller shifts the data into its serial port. The Microcontroller uses a specially developed algorithm that cancels the effects of parasitic capacitance and calculates the true ratio Cr/Cs. When the ratio is equal to one (1), the pressure difference between the two capacitors is known to be zero. A ratio less than one corresponds to a positive pressure difference and a ratio greater than one to a negative pressure difference. The ratio is linearized and temperature corrected to produce an accurate pressure signal, which is sent back to the ASIC for D/A conversion. May 1998 8-3 ACCURACY CALCULATIONS UM340-1 8.3.3 D/A Conversion and Current Signal Transmission The pressure signal received by the ASIC is applied to a 16-bit D/A Converter and Multiplexer. The Multiplexer sends serial clock and display information to the optional Smart Display board, where it is decoded and displayed on the Smart Display as pressure in engineering units. The D/A Converter translates the digitized pressure signal into a pulse width-modulated signal with a pulse width directly proportional to the magnitude of the process pressure. The pulses are filtered and applied to an operational amplifier, which drives a V/I converter, whose output is a Darlington transistor pair acting as a pass transistor that outputs a standard 4-20 mA current signal to the network (output loop). 8.3.4 Communication Format The Model 340 communicates, via the HART protocol, with the HART Communicator and any Primary Master controller connected to the network. HART communication uses phase-continuous frequency-shift-keying (FSK) at 1200 bits/sec and frequencies of 1200 Hz (logic 1) and 2200 Hz (logic 0). HART communication is superimposed (AC coupled) on the analog 4-20 mA signal. Because the digital signaling is high frequency AC, its DC average is zero and does not interfere with analog signaling. A 2-pole active filter connected to the loop input receives HART transmissions. The filter effectively rejects low frequency analog signaling and other out-of-band interference, preventing a compromise of the digital reception. The filtered signal is applied to a Zero Crossing Detector, which converts the filtered information into clean pulses of uniform amplitude before introduction to the Bell 202 modem. The modem receives and processes (e.g., demodulates) the serial FSK signal (Rxa) and outputs the signal (Rxd) to the Microcontroller where serial to parallel conversion is performed. In response to the received signal, the Microcontroller outputs a signal (Txd) to the modem where it is modulated and fed into the feedback circuit of the V/I Converter for transmission (Txa) over the loop. 8.4 TRANSIENT SUPPRESSOR OPTION The integral transient suppressor operates using a spark gap and zener diode to protect both the positive and negative signal terminals from transient spikes. Positive or Negative Terminal Board Terminal Gas Filled Spark Gap X03071S0 Zener Diode Internal Connection To Electronics Module Transmitter Enclosure Connected to Earth Ground The spark gap is capable of conducting large amounts of current, but its response time is long compared to the rise time of most transients. The faster zener diode begins conducting during the rapidly rising portion of the transient, with the current flow through the zener diode limited by the inductor. Once the spark gap begins to conduct, the current flow through the zener diode is reduced and the large transient current flows from the signal terminal, through the spark gap, to the transmitter enclosure. The spark gap continues to conduct until the current falls below 0.5 amperes. n 8-4 May 1998 UM340-1 MODEL DESIGNATIONS AND SPECIFICATIONS 9.0 MODEL DESIGNATIONS AND SPECIFICATIONS This section contains the model designation tables, a comprehensive accessory list, functional and performance specifications, and hazardous area classifications for Model 340 Pressure Transmitters.

Default configuration information can be found in Appendix C. Below is a block diagram of the function block arrangement in the transmitter. Sensor Input Write Protect Section A.1 Section A.3 Characterizer Operator Display Section A.5 Section A.4 Totalizer Xmtr ID Section A.6 Section A.2 M TOT P Alarm Section A.7 PID ON PID OFF T SetPoint T&H P Section A.9 F PID S C S Section A.10 C Auto/ Manual Characterizer V Section A.11 Section A.8 P - Process Variable S - Setpoint V - Valve T - Tracking Value C - Auto/Manal Status F - Feedback Signal M - Measure Variable TOT - Total Value - Connector to Operator Display Output X03064S2 FIGURE A-1 Function Block Arrangement in Model 340 Transmitters May 1998 A-1 APPENDIX A - FUNCTION BLOCKS UM340-1 A.1 WRITE PROTECT BLOCK The write protect parameter, when configured as “on,” blocks all HART commands which write to the transmitter. The transmitter will still be accessible by a Model 275 HART Communicator or other HART Masters, but these devices will only be able to read data from the transmitter. For example, if write protect were “on,” the transmitter could not be re-ranged. To enable write commands, configure the write protect parameter as “off.” A.2 SENSOR INPUT BLOCK The Sensor Input Block allows the user to configure those parameters which pertain to the pressure sensor. Sensor Input Block parameters are listed below; a description of each parameter then follows. Measured Variable Units ..........................................inH2O, inHg, ftH2O, mmH2O, mmHg PSI, BAR, mBAR, g/sq cm, kg/sq cm, PA, kPA, Torr, Atm Measured Variable Range Lo............................................................... -999999 to 999999 Measured Variable Range Hi ............................................................... -999999 to 999999 Damping Time Constant ........................................................................... 0 to 30 Seconds Transfer Function ...............................................................................Linear, x1/2, x3/2, x5/2 Transfer Function Cutoff .................................................................................... 0 to 30% Zero Dropout...................................................................................................... 0 to 30% Measured Variable Units These are the recognized pressure units within the HART Protocol. Pressure units are selected from a preconfigured list. Other pressure units must be converted to one of these 14 units. Measured Variable Lo (MV Lo) & Measured Variable Hi (MV Hi) These two parameters determine the range of the transmitter. The MV Lo parameter represents the pressure that will cause the transmitter to output 4 mA. The MV Hi parameter represents the pressure that will cause the transmitter to output 20 mA. These two parameters are non-interactive. Changing one does not effect the other. Furthermore, these parameters can be configured to make the transmitter forward acting or reverse acting, that is, the MV Hi parameter does not have to be configured for a higher pressure than the MV Lo parameter. For example, 100 to 0 PSI is an allowable range with 4mA being transmitted at 100 PSI and 20mA being transmitted at 0 PSI. The actual limits for the MV Lo and Hi parameters, as well as the span, are determined by the particular sensor range at hand. The Upper Sensor Limit (USL) and Lower Sensor Limit (LSL) are listed along with the Sensor Input Block parameters when using a HART Communicator; otherwise, check the transmitter model number against the model designation list in Section 9 for these limits. A-2 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS Damping The Damping parameter is used to configure the time constant for the transmitter. This can be used to quiet noisy process signals; however, when configuring this parameter remember that it takes 4-5 time constants to respond to 99.9% of a step input change. The default damping value is one second. Transfer Function The transmitter has several built in transfer functions for extracting the flow signal from various, common primary flow elements. The most common transfer function is the square root (x1/2) used with orifice plates. Also included are x3/2 and x5/2 transfer functions for use with wedge and V-notched weir flow elements. If the transmitter is not being used with one of these flow elements, simply select a linear transfer function. Transfer Function Cutoff The square root transfer function has high gain near 0% input. To prevent small input changes (noise) from being amplified excessively, a linear segment is used on the low end of the curve. The point at which this linear segment ends and the actual transfer function begins is the Transfer Function Cutoff. This is user configurable between 0% and 30% of input. Zero Dropout The Zero Dropout parameter can be used in conjunction with the Transfer Function Cutoff parameter. This parameter is a value below which the transmitter’s output will be 0%. This can be used with extremely noisy process signals where the linear approximation method does produce the desired results. This is user configurable between 0% and 30% of input. Active Input The last feature of the Sensor Input Block is not a parameter but a tool to configure the MV Lo and Hi parameters. If desired, the measured variable range may be configured against a precision pressure source in place of simply typing the range into the MV Lo and Hi parameters. The Active Input feature will show the user the “live” input pressure as well as the MV Lo and Hi parameters. The user then applies zero and span pressures from a precision pressure standard and copies those values directly into both the MV Lo and Hi parameters. This procedure allows the HART Communicator to mimic the operation of the local magnetic switches. For detailed information on using the Active Input feature or the local magnetic switches, see Section 6. May 1998 A-3 APPENDIX A - FUNCTION BLOCKS UM340-1 A.3 CHARACTERIZER The Characterizer Block is a 10-segment, user-configurable transfer function. This function block can be used to linearize either an unusual flow element, an odd-shaped tank, or in a process control application, a non-linear valve. Characterizer Block parameters are listed below, with descriptions following. Characterizer......................................................................................................... On/Off Characterizer Position..............................................Transmitter Output/Controller Output X0 . . . X10 .................................................................................................0.0 to 100.0% Y0 . . . Y10 .................................................................................................0.0 to 100.0% Characterizer This parameter is used to turn the characterizer on or off. Characterizer Position This parameter determines whether the Characterizer Block is located before or after the Controller Block. The characterizer can be used in conjunction with any of the built-in transfer functions if desired. X0…X10 and Y0…Y10 These parameters specify the values for the 10 x-y coordinates that make up the characterizer segments. The coordinates are always specified in percent. A.4 TOTALIZER BLOCK The Totalizer Block is used to totalize the measured variable. This is typically done with differential pressure transmitters when the measured variable represents the flow rate, although the totalizer is available in all Model 340 transmitters. At power-up the totalizer begins counting. Go to the Model 275 HART Communicator’s Quick Access Key menu to start, stop, or reset the totalizer at any time. The totalizer will stop counting when a configurable parameter is changed using either the Communicator or the magnetic pushbuttons. Restart the totalizer from the Quick Access Key menu on the Communicator. Totalizer Block parameters are listed below, with a description of each following. Fullscale Value.........................................................................................0.001 to 19999 Timebase.................................................................................. SEC/MIN/HR/DAY/WK Multiplier .................................................................................................0.001 to 19999 Zero Dropout............................................................................................... 0.0 to 30.0% Count Units........................................................................................4-Character ASCII Local Display ...........................................................................................Enable/Disable A-4 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS Fullscale Value and Timebase The Fullscale Value and Timebase parameters define the rate at which the totalizer counts for a 100% input signal. Accordingly, a 50% input signal will cause the totalizer to count at 50% of this rate. Multiplier If the fullscale value is too large to yield a meaningful display, a multiplier can be configured to indicate that the configured fullscale value needs to be multiplied by this number to obtain the actual totalized value. Zero Dropout The Zero Dropout parameter is used to force the totalizer to stop counting when the measured variable falls below the configured value. There is no deadband associated with the zero dropout feature. The Totalizer Block zero dropout feature is independent of the Sensor Input Block zero dropout feature. Count Units This 4-character ASCII tag is used to indicate the totalizer units. Examples could be GAL for gallons or BARR for barrels. Local Display The Local Display parameter is used to add the total value to the variables available at the local display. If the Operator Display Block’s local display code is configured as Total Only, the total will be the only variable available on the local display and this parameter has no bearing. A.5 OPERATOR DISPLAY BLOCK The Operator Display Block is used to configure the operation of the local Smart Display. Operator Display Block parameters are listed below; a description of each parameter then follows. Process Variable Range Lo ...................................................................... -19999 to 19999 Process Variable Range Hi ...................................................................... -19999 to 19999 Process Variable Units......................................................................... 4-Character ASCII Auto Rerange ........................................................................................ Enable or Disable Local Display Code ................................. MV; PV; %; MV, PV, and %; or Totalizer Only Autotoggle............................................................................................................. On/Off Toggle Time............................................................................................. 1 to 30 Seconds Process Variable Lo (PV Lo), Hi (PV Hi) and Units (PV Units) The PV Lo and PV Hi parameters are used to apply engineering units to the configured MV range. For example, the MV range might be 0 to 100 inH2O across an orifice plate. This may represent an actual flow of 0 to 500 GPM. The PV Lo and Hi parameters could be configured as 0 and 500 respectively, and the PV Units as GPM. This range could then be shown on the local Smart Display in place of the MV Range or May 1998 A-5 APPENDIX A - FUNCTION BLOCKS UM340-1 percent. If no Smart Display is installed, this range could still be meaningful as other HART devices, such as the HART Communicator, can read and display this value. Auto Rerange The Auto Rerange parameter can be used to link the MV range and PV range. By configuring the Auto Rerange parameter to “on” and making a change to either the MV range or PV range, the transmitter will automatically calculate a new range for the other of the two variables. This enables the user to re-calibrate a DP flow transmitter in flow units rather than pressure units, eliminating the need to do tedious calculations through the square root extractor. Consider the following example: Original PV Range Original MV Range New PV Range Automatically Calculated New MV Range 0 to 500 GPM 0 to 100 inH2O 0 to 750 GPM 0 to 225 inH2O NOTE Auto Rerange operates only with linear and square root transfer functions. It cannot back-calculate through the x3/2, x5/2, or Characterizer functions. Local Display Code The Local Display Code parameter is used to select variables for local indication. MV Units, PV Units, or Percent can be selected for a basic display. A more powerful display is selected by configuring the Local Display Code as MV, PV, and Percent. This enables all variables in all units to be displayed locally. Automatic switching between variables is enabled by configuring the Autotoggle parameter, or the user can switch manually using the local magnetic switches (see Section 6 for local operation). Also, the display can be locked to indicate only the totalizer value. Totalizer display functions are usually configured in the Totalizer Block; however, if totalizer only is selected as the Local Display Code, only the totalizer value will be indicated regardless of the Totalizer Block configuration. The following table summarizes local display operation: A-6 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS Local Display Code Controller (from Controller block) Totalizer Display (from Totalizer Block) Variables Available on Local Display MV Off Off MV MV Off On MV, Total MV On Off P in MV units, SP in MV units, V in % MV On On P in MV units, SP in MV units, V in %, Total PV Off Off PV PV Off On PV, Total PV On Off P in PV units, SP in PV units, V in % PV On On P in PV units, SP in PV units, V in %, Total % Off Off % % Off On %, Total % On Off P in %, SP in %, V in % % On On P in %, SP in %, V in %, Total MV/PV/% Off Off MV, PV, % MV/PV/% Off On MV, PV, %, Total MV/PV/% On Off P in MV units, P in PV units, PV in %, SP in MV units, SP in PV units, SP in %, V in % MV/PV/% On On P in MV units, P in PV units, PV in %, SP in MV units, SP in PV units, SP in %, V in %, Total Total Only Off Off Total Total Only Off On Total Total Only On Off Total Total Only On On Total Autotoggle The Autotoggle parameter is used to force the local display to automatically toggle through all parameters defined by the Local Display Code. May 1998 A-7 APPENDIX A - FUNCTION BLOCKS UM340-1 Toggle Time This parameter defines the time between toggling to the next variable when Autotoggle is configured “On.” A.6 TRANSMITTER ID BLOCK The Transmitter ID Block can be used to maintain identification information about the transmitter. Transmitter ID Block parameters are listed below; a description of each parameter then follows. Tag ..................................................................................................... 8-Character ASCII Descriptor ......................................................................................... 16-Character ASCII Message ............................................................................................ 32-Character ASCII Date ............................................................................................................. DD/MM/YY Device Serial Number................................................................................. 0 to 16777215 Polling Address ......................................................................................................... 0-15 Tag, Descriptor, and Message These three parameters are ASCII text and have no bearing on transmitter output. Up to an 8-character Tag, 16-character Descriptor and 32-character Message may be entered for the transmitter. Date The Date parameter uses the international DD/MM/YY format. This date can be selected by the user to indicate any date or event, such as date of installation or last date of service. Device Serial Number The 8-digit Device Serial Number is factory configured to match the serial number on the transmitter nameplate. It is not recommended that this number be changed. Polling Address The Polling Address is used to place the transmitter in either analog or digital mode. A Polling Address of 0 indicates that the transmitter is in analog mode and will output a 4-20 mA current according to its calibrated range. In analog mode, a single transmitter is connected to a Point-to-Point Network. A Polling Address between 1 and 15 indicates the transmitter is in digital mode and will output a constant 4 mA current. In digital mode, up to 15 transmitters can be connected in a Multi-Drop Network using a single twisted pair cable. For more information on Multi-Drop networks, see Section 4. A-8 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS A.7 ALARM BLOCK The Alarm Block is used to configure one or two HART alarms. Alarm Block parameters is listed below; a description of each parameter then follows. Alarm 1..................................................................................................... Enable/Disable Alarm 1 Setpoint ................................................................................. -999999 to 999999 Alarm 1 Type .................................................................................................... High/Low Alarm 2..................................................................................................... Enable/Disable Alarm 2 Setpoint ................................................................................. -999999 to 999999 Alarm 2 Type .................................................................................................... High/Low Self-Clearing NAKS.............................................................................................. On/Off Alarms Out of Service ........................................................................................... On/Off Alarm 1 & 2 Enable or disable either alarm by setting this parameter as “Enable” or “Disable.” Alarm 1 & 2 Setpoint Use this parameter to configure the setpoint for the alarm. The alarm setpoints are configured in PV units. Alarm 1 & 2 Type This parameter determines the type of alarm, either high or low. These alarms have no associated deadband. Self Clearing NAKS The not acknowledge (NAK) bit in the alarm status word is set whenever the alarm goes from a no-alarm to an alarm condition. When the alarm condition clears, the NAK bit will reset if the Self-Clearing NAKS parameter is set to On. If the Self-Clearing NAKS parameter is set to Off, the NAK bit must be reset via a HART command. Alarms Out of Service The Alarms Out of Service parameter determines if the out-of-service bit in the alarm status word is set. This bit can be sensed by HART master devices such as the HART Communicator to indicate that the transmitter is out of service and the alarm condition should therefore be ignored. May 1998 A-9 APPENDIX A - FUNCTION BLOCKS UM340-1 A.8 SETPOINT TRACK AND HOLD BLOCK Configure the Setpoint Track and Hold Block if the Controller function of the transmitter is configured “On.” Setpoint Track and Hold Block parameters are shown below, followed by a description of each. Tracking Setpoint ..................................................................................................Yes/No Power-Up Setpoint .............................................................................. -999999 to 999999 Tracking Setpoint If this parameter is configured as “Yes,” the SP tracks the process variable when the controller is in manual mode. If it is configured as “No,” non-tracking, the SP remains at its configured value while the controller is in manual mode. Power-Up Setpoint The Power-Up Setpoint value is the value to which the SP is initialized to at power-up. On-line SP adjustments may be made with the HART Communicator via the Quick Access Key menu. This value also may be edited using the local magnetic switches as described in Section 6. A.9 CONTROLLER BLOCK The Controller Block provides a range of proportional-integral-derivative functions including: PID, PD, and ID. The function block is used to configure controller operation and tuning parameters. Controller Block parameters are listed below; a description of each parameter then follows. Controller Status ................................................................................................... On/Off Controller Type ............................................................................................... PID/PD/ID Action ........................................................................................................Reverse/Direct Proportional Gain (PD and PID) ................................................................... 0.01 to 100.0 Time Integral............................................................................... 0.01 to 1000 min./repeat Time Derivative.................................................................................... 0.01 to 100.0 min. Derivative Gain ............................................................................................ 1.00 to 30.00 Manual Reset (PD only) ..............................................................................0.0 to 100.0% Manual Reset Tracking (PD only)..........................................................................No/Yes Controller Status Use this parameter to turn the controller On or Off. If the controller is turned Off, the transmitter output reflects the process variable and the Setpoint Track and Hold Block and A/M Block are dormant. If the controller is turned On, transmitter output reflects the valve signal. Process variable information must be obtained digitally through HART. A-10 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS Controller Type This parameter is used to select the controller type. PID, PD, and ID types are available, with each working as described below. PID Controller The PID Controller is a reset-type controller that uses external feedback to establish the integral action. The function block forces the output to track the feedback when the controller is in manual. If the derivative time TD is set to 0.00, the derivative section is eliminated. Equations O = GE + R AUTO R = F/(TIs + 1) O = ±PG[P(1+{TDs/([TD/DG]S+1)}-S] + [1+1/TIs] MANUAL R = F - GE ∴ O = F PD Controller The PD Controller is a proportional-only controller with the manual reset that can be selected as tracking or non-tracking. The function block forces the controller output to track the feedback and, when manual reset tracking is selected, the manual reset (MR) also will track the feedback when the controller is in manual. In either case, the controller always goes back to AUTO with the output equal to the feedback. The reset value (R) then returns to the value of the MR with the time constant established by the integral time (TI). The default value of TI is 100 minutes, but it should be reduced (e.g., 0.01 minutes) when using this controller type. The TI time constant is selected for the rate at which the controller should return to normal operation after switching from manual to auto. Bear in mind that the TI time in the PD controller is not an integral time and does not affect control stability. If the derivative time TD is set equal to 0.0, the derivative section is eliminated. Equations O = GE + R AUTO R = MR/(TIs +1) MANUAL R = F - GE ∴ O = F If MRT = Yes, MR = F May 1998 A-11 APPENDIX A - FUNCTION BLOCKS UM340-1 ID Controller The ID Controller is an integral-only controller that uses external feedback to establish integral action. If the derivative time TD is set to 0.00, the derivative section is eliminated. The gain for this controller is fixed at a value of 1.00. While the displayed gain can be changed, it will not affect the controller. Equations O = (GE + F)/(TIs + 1) AUTO WHEN OUTPUT O IS CONNECTED TO FEEDBACK F O = ±PG[P(1+{TDs/([TD/DG]S+1)}-S] [1/TIs] MANUAL O=F Action This parameter is used to set the controller as direct or reverse acting. PG, TI, TD, DG, MR, and MR Tracking These parameters are used to tune the controller. The controller must be tuned specifically for each application. The use of each of these parameters is described above under the Controller Type parameter. These values can be edited on-line through the Quick Access Key menu of the HART Communicator. A.10 A/M TRANSFER BLOCK The A/M Transfer Block is used to configure the A/M switching features of the controller. The Block’s software provides a single pole, double throw switch function. When in automatic mode, the controller output is passed to the Output Block. When in manual, the manual value is passed to the Output Block. When in manual, the SP will track the process to avoid bumps when switching from manual to automatic if the tracking setpoint parameter in the Setpoint Track and Hold Block is set to “Yes.” A/M switching can be initiated from the Quick Access Key Menu of the HART Communicator or through the use of the local magnetic switches (see Section 6). A/M Transfer Block parameters are listed below; a description of each parameter then follows. Power-Up Mode ...................................................................................Automatic/Manual Automatic Mode Only ...........................................................................................Yes/No Power-Up Valve ........................................................................................... -1.0 to 110% A-12 May 1998 UM340-1 APPENDIX A - FUNCTION BLOCKS Power-Up Mode This parameter is used to configure the mode in which the controller will power-up. If automatic is selected, the Power-Up Setpoint value from the Setpoint Track and Hold Block is used as the SP and the controller will be initialized to automatic mode. If manual is selected, the Power-Up Valve value within this block is used as the output and the controller is initialized to manual mode. Automatic Mode Only If this parameter is configured to “Yes,” the controller cannot be switched to manual mode. The controller will be initialized to automatic at power-up regardless of the Power-Up Mode parameter. Power-Up Valve The power-up valve is the manual power-up value used if the controller is powered up in manual mode. On-line valve adjustments may be made using the HART Communicator via the Quick Access Key Menu. This value may also be edited via the local magnetic switches as described in Section 6. A.11 OUTPUT BLOCK The Output Block converts the internal digital signal it receives into a 4-20 mA analog output signal. The input to the block represents either the actual 4-20 mA process variable or the valve signal depending on the configuration of the Controller Block.

Fill Connection LP Shut-Off Valve Max. Range HP Shut-Off Valve Max. Range Span Vent Min. Range See Section 9 Specifications for range limit. Suppressed Span Span Min.

LP line filled with condensate HP Shut-Off Valve Distance X Vent HP FIGURE D-1 Elevated Span Example LP X03070S0 HP LP FIGURE D-2 Suppressed Span Example A brief discussion of how to make adjustments for elevation and suppression follows. Then two examples of the calculations needed to determine configuration parameters are given. Finally, a brief procedure that does not involve calculations is provided. D.1 HOW ADJUSTMENT IS MADE Because the Model 340 can handle elevation and suppression simply by setting parameters in the Sensor Input Block, it is not necessary to introduce mechanical measures, such as installing piping backwards or adding additional hardware. The range of the transmitter can be set anywhere, forward or reverse acting, as long as the following criteria are met: LRL LRV URL LRL URV URL Span = [URV - LRV] May 1998 Min Span D-1 APPENDIX D - ELEVATION AND SUPPRESSION UM340-1 Note that the URL (Upper Range Limit), LRL (Lower Range Limit), and Min Span are transmitter dependent. D.2 ELEVATION CALCULATION EXAMPLE Figure D-3 shows a sample transmitter installation. Max. Range H2 O SpG=1.0 1. Calculate the differential pressure as follows. Pressure@DP = (H × SpG)High Side - (H × SpG)Low Side 100" Min. Range where H = Height 2. Calculate the LRV when the tank is empty. LRV = (120 × 1.0)High Side - (0 × 1.0)Low Side 120" Vent LRV = +120 inH2O 3. Calculate the URV. X03070S0 URV = LRV + Span HP URV = +120 + 100 URV = 220 inH2O LP FIGURE D-3 Elevation Calculation Example Therefore, transmitter range should be 120 to 220 inH2O. D.3 SUPPRESSION CALCULATION EXAMPLE Figure D-4 shows a sample transmitter installation. 1. Calculate the differential pressure as follows. Pressure@DP = (H × SpG)High Side - (H × SpG)Low Side where H = Height 2. Calculate the LRV when the tank is empty. LRV = (0 × 1.0)High Side - (100 × 1.0)Low Side LRV = -100 inH2O 3. Calculate the URV. URV = LRV + Span URV = -100 + 100 Max. Range Span 100" H2O SpG=1.0 Min. Range HP LP X03070S0 LP Line Filled with Condensate FIGURE D-4 Suppression Calculation Example URV = 0 inH2O Therefore, transmitter range should be -100 to 0 inH2O. D-2 May 1998 UM340-1 APPENDIX D - ELEVATION AND SUPPRESSION D.4 RECOMMENDED METHOD FOR 340 TRANSMITTERS An alternative to making the above calculations and entering derived values into the Sensor Input Block is to shift the span directly using the HART Communicator while adjusting the process levels. 1. Range the transmitter using the HART Communicator as for a zero-based span (e.g., 0-100 inH2O). 2. Install the transmitter on the process. 3. Fill the impulse pipe (wet legs) to the transmitter, but maintain the process at 0 (e.g., empty tank). 4. Perform one of the following: • Use the Active Input feature of the Communicator (access the Online/Configuration Xmtr/Sensor Input Menu) to set the current pressure as the LRV. The configured span will be retained. • Use the Z magnetic switch to set the current pressure as the LRV. The configured span will be retained. This completes the procedure. n May 1998 D-3 APPENDIX D - ELEVATION AND SUPPRESSION UM340-1 D-4 May 1998 UM340-1 APPENDIX E - CENELEC EEX D INSTALLATIONS E.0 APPENDIX E - CENELEC EEX D INSTALLATIONS The information his appendix applies only to transmitters with a CENELEC EEx d [ia] ia approval shipped after 12/1/96. UM340-1 sections amended by this appendix are: Section 4.3.5 Power Supply Requirements Section 9 Model Designations and Specifications MODEL DESIGNATION - The letter ‘M’ appears in the 15th (last) position in the model number stamped on the permanent instrument nameplate. An example of a valid model number is 340DDBHAAB5N12M. HAZARDOUS AREA CLASSIFICATION - CENELEC, EEx d [ia] ia, IIC T6, T5 The Model 340 with EEx d [ia] ia certification is suitable for use in Zone 1 explosive atmospheres only. The basic protection technique is a flameproof enclosure (“d”) with an intrinsic safety barrier (“[ia]”) incorporated into the terminal board. This built-in barrier insures both the electronics module and sensor are intrinsically safe (“ia”). This barrier will cause errors in the 4-20 mA signal if the instrument is operated outside the specified operating range. WARNING The model 340 with EEx d [ia] ia certification is only suitable for use in Zone 1 explosive atmospheres when connected to equipment that does not generate or use more than 250 Vac rms or DC. POWER SUPPLY REQUIREMENTS - A special terminal board is installed to protect the sensor assembly from excessive current draw during fault conditions. The following specifications apply. Minimum Terminal-to-Terminal Compliance Voltage:............16.5 Vdc Maximum Terminal-to-Terminal Compliance Voltage:...........26 Vdc Maximum Load (ohms): ........................................................See graph on next page Applying a terminal-to-terminal voltage greater than 26 Vdc can damage terminal board components. Calculate the terminal-to-terminal voltage for your loop as follows. Max. T-T Voltage = power supply voltage - (0.00385)(total loop resistance) Min. T-T Voltage = power supply voltage - (0.0225)(total loop resistance) May 1998 E-1 APPENDIX E - CENELEC EEX D INSTALLATIONS Refer to UM340-1 for all other information concerning an EEx d [ia] ia certified Model 340. 333 250 X03047S1b INSTALLATION - Correct voltage polarity must be applied to transmitter terminals. Applying a reverse polarity voltage can damage the terminal board requiring it to be replaced. See the wiring diagrams in UM340-1, Section 4 Installation for correct voltage polarity. 422 Network Resistance, Ohms Select a power supply that allows the terminal-to-terminal voltage to remain between 16.5 and 26 Vdc over the entire loop current range (typically, 3.85 mA to 22.5 mA).

An example follows. Assumptions: Required Calibration = 0-100 in H2O Static (line) Pressure = 2000 psi Correction: Required Correction = (0.9%/1000 psi) x 2000 psi = 1.8% Actual Calibration = 0-98.2 in H2O n April 1997 F-1 APPENDIX F - STATIC PRESSURE CORRECTION F-2 UM340-1 April 1997 UM340-1 WARRANTY WARRANTY The Company warrants all equipment manufactured by it and bearing its nameplate, and all repairs made by it, to be free from defects in material and workmanship under normal use and service.
