Setting the switching point:
Note!
During adjustment or testing, the switching
point must always be approached from

To ensure safe switching under any ambient
conditions, the switching point is to be ad-
justed to a value of approx. 5 % before the
mechanical stop (OPEN – CLOSED).
For CLOSED position:
1. Initialize positioner.
2. Use the MAN function to move the
positioner to 5 % (see LCD).
3. Adjust the tag using the yellow adjust-
ment screw (2) until the tag enters or
leaves the field and the switching ampli-
fier responds. You can measure the
switching voltage as an indicator.
Contact function:

For OPEN position:
1. Initialize positioner.
2. Use the MAN function to move the
positioner to 95 % (see LCD).

leaves the field of the proximity
