Proceed as follows when using a drive over gear wheels for adjustment of the potentiometer:
Adjusting the po-
tentiometer
1. Loosen the clamp bolt (1).
2. With the switching shaft stationary: Turn the gear wheel.
3. Screw the clamp bolt (1) in tightly.

* Connection voltage according to the version
used: 12 – 36V AC/DC or 110 – 250V AC/DC
The heating serves to prevent water condensation in the switch room. This heating is designed so that accord-
ing to the voltage, a heat output of approx. 2,5 Watts or 4 Watts is available. Depending on the order, the corre-
sponding supply voltage amounts to 12 − 36V AC/DC or 110 − 250V AC/DC. The PTC heating is self-regulating
and temperature-limiting, and thus leads to an automatic adjustment to the ambient temperature.
ATTENTION
Risk of accidents due to hot surfaces
Contact with the surface of the heating may lead to severe burns.
► Wear personal protective equipment.
► Wait until the surface has cooled.
