Supply voltage connection and Optocoupler inputs (pos. G)
For the sensor voltage supply a small HAN 3A metal (metric thread) with an 8 pin insert is used. In
addition to the voltage supply the opto coupler inputs are used with this connection.

A corresponding cable plug is part of the standard scope of supply.
Note
The connecting cable for the power supply should be kept short.
Up to 20 m length use a 2 x 1 mm ² cable. For longer cables, the
cross section must be increased accordingly (see power
consumption data in chapter "2.1 Technical data").
Attention
The earth ground/central machine ground must not be
connected to + 24 VDC.
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".

The combination of measurement start 1, 2 and 3 can be adjusted in the system configuration
menu.
Note
Measurement start signal can be issued either via the process channel or
via an optocoupler. Simultaneous measurement start signals result in
fault messages.
