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! 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-SSI-E-13 3 PRODIS®-SSI Instruction Manual Description The process meter PRODIS®-SSI 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-SSI-E-13 www.asm-sensor.com ASM GmbH PRODIS®-SSI Instruction Manual Wiring Signals Connector X1 pin no.

When the meter is switched on a short self test sequence will start with all LED segments on and then the version of the process meter will be displayed. After that procedure PRODIS®-INC is in the normal mode. Operation keys and display Explanation of the operation keys and display elements: LED 2 Sign LED 1 : Key to control the programming menus : Multifunction keys for parameter settings : Multifunction key to reset the display and to store the parameters in a non-volatile memory Note: + 8 means: hold key and press MAN-PD-SSI-E-13 www.asm-sensor.com . ASM GmbH PRODIS®-SSI Instruction Manual Explanation and operation of the functions Normal mode, displaying the position value The displayed mesurement value will be calculated as Measurement value • Multiplier Reading = Divisor + Offset value Multiplier, divisor, decimal divisor and offset are user definable parameters (for calculation examples see appendix). When the display range of ±999999 is exceeded, the display shows an exponential format with the least significant digits alternatively. Tare function To activate the tare function, press the front button or set the control input terminal 1 to low (0V). With the tare function active, the display of the meter will be set to the offset value and the decimal point will be flashing while the tare function is active. Pressing the button again deactivates the tare function. Offset function The offset function allows the user to set and change the offset value of the meter directly in the normal mode. SSI Code Programmable Gray or Dual Code data transmission parameter can be entered under teach-in menu ”C”. SSI Number Polarity Programmable use of the minus sign in the data transmission can be entered under teach-in menu ”SIG...” by setting this function ”On” for data transmission with a minus sign and ”Off” for data transmission with only absolute values without a minus sign. SSI Sampling Rate Programmable SSI sampling rate can be entered under teach-in menu ”clc” and can be set to 100, 200 or 500 kbit. SSI Data Format Programmable SSI data format can be entered under teach-in menu ”dAt” and can be set to between 12 and 32 bit. SSI Counting Direction Programmable SSI counting direction can be entered under teach-in menu ”drEh” and can be set to ”r” for rising counting and ”l” for decreasing counting.

ASM GmbH PRODIS®-SSI 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 and the tare parameter “tAr” is set to OFF. 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-SSI-E-13 11 PRODIS®-SSI 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: 9600 Bd, programmable Net transmission rate Max. 50/s approx.
