3.3 Switching point setting
During the switching point setting of the contacts, contact
with live parts is possible. Only execute the setting when the
switch lever is not on the switch curve to avoid too strong
a reduction of the lifetime. Always set the emergency limit
switch first.
Standard version
In the standard version, the central screw of the disc cam is loosened.
A disc cam, which can be adjusted over 4° distances, is assigned to
every contact. The disc cams all have gearing as well as a positive
linkage with the worm wheel. After the set-up has been carried out, the
central screw must be firmly retightened.

3.4 Cams and settings
Disc cam with front setting
For the disc cams with front setting (ordering suffix -1600), the dowel of
the disc cam must be pushed in using the screwdriver, which is located
inside the switch (see figure). At the end of the process, the dowel must
autonomously return to the locking position, thus restoring the positive
linkage. The central screw must not be loosened to that effect.
