5.2 Connection

The voltage supply and signal output are connected via the spring-

loaded terminals in the housing.

The connection to the display and adjustment module or to the inter-

face adapter is carried out via contact pins in the housing.

Information:

The terminal block is pluggable and can be removed from the

electronics. To do this, lift the terminal block with a small screwdriver

and pull it out. When reinserting the terminal block, you should hear it

snap in.

Proceed as follows:

1. Unscrew the housing cover

2. Loosen compression nuts of the cable glands

3. Remove approx. 10 cm (4 in) of the cable mantle (signal output),

strip approx. 1 cm (0.4 in) insulation from the ends of the indi-

vidual wires

4. Insert the cable into the sensor through the cable entry
