For safety related applications additional mechanisms (de- vices) are necessary to maintain safety and to avoid damage. Disregard of this advice releases the manufacturer from product liability. The meter must be operated only within values specified in the data sheet. Connection to power supply must be performed in accordance with safety instructions for electrical facilities and performed only by trained staff. Danger of Destruction! The inputs of the process meter must not be connected to current sources with more than 30 mA max. It has to be guaranteed that the excitation voltage agrees with the indicated value on the type label. Do not open the process meter. ASM GmbH www.asm-sensor.com MAN-PD-ADC-E-13 3 PRODIS®-ADC Instruction Manual Description The process meter PRODIS®-ADC is designed for use with analog position sensors to display angles and displacements. A high-resolution analog/ digital converter can process two input signals of each 0 … 10 V, 0.5 … 10 V, 0/4 … 20 mA or voltage divider. Thus the difference of to measurement signal can be measured. To display mass units like inch, mm or degrees between given start and end values the meter can be scaled by the user. Via two control inputs the functions Tare and Display Hold can be activated. The sensor excitation voltage is supplied from the meter. With four membrane keys the parameters for signal processing, scaling and comparator function can be programmed. Optional comparator function with two relays and four NPN open-collector outputs are available. Mechanical mounting Mounting clamps Hook in the rear notch and push the end down until the front notch is locked Turn the set screw with a slotted screwdriver until stop at the front plate. 4 MAN-PD-ADC-E-13 www.asm-sensor.com ASM GmbH PRODIS®-ADC Instruction Manual Wiring basic unit Signals Connector X1 pin no.

MAN-PD-ADC-E-13 9 PRODIS®-ADC Instruction Manual Explanation and operation of the functions Scaling for maesurement input signals 0...10 V, 0/4...20 mA The input of the start and end value for the displayed value range 0...10 V resp. 0/4...20 mA will be made by the menu positions “start value” and “end value”. Example: Sensor with a measurement range of 2000 mm and a output signal of 4...20 mA, wanted display range 0 … 2000.0 Setting: SIG: I42, start value: 0, end value: 20 000, decimal point between the first and second position from the right hand side. Scaling for position sensors with potentiometric signal An utilization factor nP considers measurement range limits and individual sensitivity of the potentiometer. The display range is set by start and end value. nP will be calculated as a product of (sensitivity) E x L (measurement range), both specifications can be taken from the type label. When the sensor has been changed the re-calibration of the meter is very easy by changing nP. Example A: Linear sensor with a measurement range of 1250 mm and output R1K, sensitivity: 0,756 mV/V/mm, wanted display: 0 … 1250.0 mm. Setting: nP = 0.765 x 1.250 = 0.945, start value: 0, end value: 12500, decimal point between the first and second position from the right hand side. Example B: as A, but wanted display range: 0 … 49.21 inch. Setting: nP = 0.765 x 1.250 = 0.945, start value: 0, end value: 4921, decimal point between the second and third position from the right hand side. Example C: angle sensor with a used range of 90 degrees and output R1K, sensitivity: 2.846 mV/V/degree, wanted display range: 0 … 90 degrees. Setting: nP = 0.002846 x 90 = 0.25614, start value: 0, end value: 90. Tare function Activated by the front button or via the control input the display of the meter will be set to the offset value, the decimal point is flashing while the tare function is active. Pressing the button again deactivates the tare function. Offset function The offset function allows to set and change the offset value of the meter directly in the normal mode. 10 MAN-PD-ADC-E-13 www.asm-sensor.com ASM GmbH PRODIS®-ADC Instruction Manual Explanation and operation of the functions (continuation) Teach-in scaling with start value and end value A display value range is assigned to a measurement range by teach-in. The display value range is defined by start and end value. The teach-in procedure will be released via the programming menu with t-In = E. Set the input signal to the first value and then press . Then set the input signal to the second value and press . To avoid unintentional changes with t-In = A the teached scaling remains active, however, the teach-in procedure itself is disabled.

ASM GmbH PRODIS®-ADC Instruction Manual Control inputs 1 and 2 Functions TARE, FREEZE, KEY-LOCK, DATA-SEND These functions can be activated by two control inputs. The activation of an input is made by connecting the input with GND. An open input or a connection with 24 V sets the function of the control input to inactive. Description of the functions Control input 1, TARE function The activation of the Tare function sets the display value to zero resp. to the offset value from the offset menu input. The TARE compensation will be held as long as the control input 1 is active. An active control input 1 avoids any tare operation with the S key at the meter frontside. Control input 2, functions FREEZE, KEY-LOCK, DATA-SEND The used function of the control input 2 is set in the setting menu with the “Cntr” menu: Cntr: 1 FREEZE Display “freeze” Cntr: 2 KEY-LOCK Programming blocked Cntr: 3 SEND The displayed value will be sent via the RS-232 interface Cntr: 4 SEND-CYC The displayed value will be sent periodically every 10 ms via RS-232 ASM GmbH www.asm-sensor.com MAN-PD-ADC-E-13 13 PRODIS®-ADC Instruction Manual RS-232 interface Transmission of a position value Send to PRODIS®: Response of PRODIS®: “r” CR, sign, n5, n4, n3, n2, n1, n0 with ni: ASCII characters, leading digits filled with “0” Sign: positive sign = Space “ “ Tare function On/Off Send to PRODIS®: PRODIS® function: “n” Tare function on/off Data format 1 start bit, 8 data bits, 1 stop bit, no parity Baud rate: programmable Net transmission rate Max. 50/s approx. 14 MAN-PD-ADC-E-13 www.asm-sensor.com ASM GmbH PRODIS®-ADC Instruction Manual Examples for signal wiring +24 V Excitation GND UB = 24 V 0 ... 10 V 0,5 0.5 ... 10V Excitation +24 V UB = 24 V 4 ... 20 mA Load 100 Ω Excitation +24 V Excitation GND UB = 24 V 0/4 ... 20 mA Load 100 Ω Excitation +5 V UB = 5 V 0.5 ... 4,5 4.5 V 0,5 R1K Signal 1+ +5 V Signal 2+ Excitation ASM GmbH www.asm-sensor.com MAN-PD-ADC-E-13 15 Declaration of Conformity The Process Meter Manufacturer: ASM GmbH Am Bleichbach 18-22 85452 Moosinning / Germany Model: Options: PRODIS®-ADC -24VDC, -230VAC, -REL2 complies with the following standards and directives: Security: Low voltage directive: 2006/95/EEC Applicable standards: EN 61010-1:2010 EMC: EMC directive: 2004/108/EEC Applicable standards: EN 61326-1:2006 Note: When using the comparator option -REL2/NPN4 ensure that the connected circuit complies also with the EMC directive.
