Setting the switching point

NOTICE
During adjustment or testing, the switching
point must always be approached from
mid-position (50 %).
To ensure safe switching under any ambient
conditions, the switching point should 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 LC display).
3. Adjust the tag using the yellow adjust-
ment screw (2) until the tag enters or
leaves the field and the switching am-
plifier responds. You can measure the
switching voltage as an indicator.
Contact function:
