PRODIS®-SSIInstruction Manual

Do not use PRODIS®-SSI process meters in safety critical ap-plications where malfunction or total failure of the sensor may cause danger for man or machine.

For safety related applications additional mechanisms (de- vi-ces) are necessary to maintain safety and to avoid damage.

Disregard of this advice releases the manufacturer from pro- duct 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.

It has to be guaranteed that the excitation voltage agrees with the indicated value on the type label.

Do not open the process meter.

Danger ofDestruction!

The process meter PRODIS®-SSI is designed for use with analog position sensors to display angles and displacements. A high-resolution analog/di-gital 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 memb-rane 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.

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.

Explanation and operation of the functions

Normal mode, displaying the position valueThe displayed mesurement value will be calculated as

Measurement value • MultiplierReading = + Offset value Divisor

Multiplier, divisor, decimal divisor and offset are user definable parame-ters (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 functionTo 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 functionThe offset function allows the user to set and change the offset value of the meter directly in the normal mode.

SSI CodeProgrammable 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 FormatProgrammable SSI data format can be entered under teach-in menu ”dAt” and can be set to between 12 and 32 bit.

SSI Counting DirectionProgrammable 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.

Functions TARE, FREEZE, KEY-LOCK, DATA-SENDThese 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 functionThe 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-SENDThe 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 blockedCntr: 3 SEND The displayed value will be sent via the RS-232 interfaceCntr: 4 SEND-CYC The displayed value will be sent periodically every 10 ms via RS-232

Control inputs 1 and 2

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 resolu-

tion.4. Setting of the decimal point.

Examples for the adjustment of the scaling parameters for different sensors:

Display for POSICHRON position sensor PCFP23-1000-10-SSI-M12Least Significant Digit (LSD) of the display must correspond to 0.1 mm

Resolution of the position sensor: 10 µm = 0.01 mmResolution of the display: 0.1 mm

Multiplier 0.01 1 = =Divisor 0.1 10

Set the decimal point between the first and second digit from the right hand side.

Display for WS position sensor WS19KK-8000-TSSILeast Significant Digit (LSD) of the display must correspond to 0.1 mm
