Limit switch for wire rope path (as option)

12.5.1 Setting of the switching points
At first, adjust the cams for "lowering". Therefore lower the load to its lowest end position and adjust the
cams. The number of switching cams can vary job-oriented.
1 Unscrew the screws of the cover and remove
the cover.
2 Loosen the central screw (1)
3 Set the switching point of every cam disc
(A,B...and possibly other) with set screw
(2A,2B...and possibly other).
4 Tighten the central screw (1) again.
5 Install the cover again and make sure the
rubber seal is placed correctly.
Make sure that 2-3 rope layers remain on the
drum in the lowest load position.
Adjustment for "lifting" is done analogous.
Afterwards drive carefully to the end positions to
check correct adjustment.
