Instruction Manual
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.

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.

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.

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.

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
