Note
Pin 6 is connected with pin 7 of connection X2.
Pin 7 is connected with pin 1 of connection X2.
Note
The cable for the voltage supply should be kept as short as
possible.
Attention
Pin 1 (+24 VDC) must not be connected with operation earth.
Optocoupler inputs for fast measurements
For real-time measurements it is possible to start measurement with external optocoupler inputs.
The optocoupler function with a control voltage of 20 to 28 VDC. For connections see table on
page 40 "Pin configuration of voltage supply connection".

Note
“Measurement start” signals can be issued either via the process channel
or via an opto coupler. Simultaneous measurement start” signals result in
fault messages.
