3 Safety instructions Do not use PRODIS -SSI process meters in safety critical applications where malfunction or total failure of the sensor may cause danger for man or machine. 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 MAN-PD-SSI-E-13 3

4 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, 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 ASM GmbH

8 Operation Check all lines, connections and excitation voltages before switching on the equipment! 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: + means: hold key and press. 8 MAN-PD-SSI-E-13 ASM GmbH

9 Explanation and operation of the functions Normal mode, displaying the position value The displayed mesurement value will be calculated as Measurement value Multiplier Reading = + Offset value Divisor Multiplier, divisor, decimal divisor and offset are user definable parameters (for calculation examples see appendix). When the display range of ± 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 MAN-PD-SSI-E-13 9

11 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 MAN-PD-SSI-E-13 11

13 Determination of the scaling parameters 1. Determine the resolution of the position sensor and conversion of the display units. 2. Specify the resolution of the display. 3. Selection of multiplier and divisor scaling factors for the desired resolution. 4. Setting of the decimal point. Examples for the adjustment of the scaling parameters for different sensors: Display for POSICHRON position sensor PCFP SSI-M12 Least Significant Digit (LSD) of the display must correspond to 0.1 mm Resolution of the position sensor: 10 µm = 0.01 mm Resolution of the display: 0.1 mm Multiplier = = Divisor Set the decimal point between the first and second digit from the right hand side. Display for WS position sensor WS19KK-8000-TSSI Least Significant Digit (LSD) of the display must correspond to 0.1 mm Resolution of the position sensor: mm Resolution of the display: 0.1 mm Multiplier = = Divisor Set the decimal point between the first and second digit from the right hand side. ASM GmbH MAN-PD-SSI-E-13 13

14 Determination of the scaling parameters (continuation) Display for WS position sensor WS19KK-8000-TSSI Least Significant Digit (LSD) of the display must correspond to 0.01 inch Resolution of the position sensor: / 25.4 inch Resolution of the display: 0.01 inch Multiplier = = Divisor 25.4 x Set the decimal point between the second and third digit from the right hand side. Display for Multi-turn Angular Encoder with SSI Output and Reso- lution of 12 Bit / Revolution Least Significant Digit (LSD) of the display must correspond to 0.1 degree Resolution of the position sensor: 360 / 4096 degree Resolution of the display: 0.1 degree Multiplier = = = Divisor 4096 x Set the decimal point between the first and second digit from the right hand side. 14 MAN-PD-SSI-E-13 ASM GmbH
