Design and Functional Principle
. NOTE
15. Drive the actuator to the second desired mechanical position.
16. Adjust the bottom actuating disc (7.3) by hand until the output signal
on terminals 51 and 52 changes.
If you turn the actuating disc beyond the switching point up to the next
switching point, you can set a high-low or a low-high change.
To avoid the actuating discs being accidentally adjusted during operating,
they are relatively sluggish. The following remedy might be of help
if you are having trouble with the adjustment: open and close the actuator
several times while holding the actuating discs. This temporarily
reduces the friction. This allows an easier and finer adjustment.
