Adjusting the
complete cam
block
NOTE
A block adjustment is offered when the adjusted individual switching points should
not be altered to each other, for example, when the wire length is changed. With a
block adjustment, the relative adjustment of the individual contacts to each other
remains unchanged.
1. Loosen the nut (3).
2. Turn the complete switching block by hand to the required switching position.
3. Tighten the nut (3) to a tightening torque of 2,5 Nm.
4. All adjustments must be looked at in an inspection round and checked for functionality.
5. Mount the cover of the GTES, see section 6.7.

A cam disc group is assigned to each contact, consisting of a cam disc (1), adjustable cam (2), adjustment
worm (3) and toothed spacer (4). The adjustable cam (2) is connected via positive locking to the block
adjustment sleeve (6) over the spacer (4). The adjustment worm (3) with a self-locking feature transfers the
torque further by means of positive locking from the adjustable cam (2) to the toothing of the cam disc (1). The
cam disc (1) can be adjusted by rotation of the adjustment worm (3) at a ratio of 108:1 (1 revolution of the
adjustment worm = 3,333° on the cam disc) in peripheral direction. The effective cam angle (10) and the usable
angle of the cam disc (11) are shown in the figure. x* and y* depict the views.
Adjusting individ-
ual cam discs
To adjust the switching points, proceed as follows:
1. Loosen the capstan nut (7).
Turn the selected cam discs (1) to the required, approximate switching positions.
2. Tighten the capstan nut (7) to a tightening torque of 2,5 Nm.
3. Using a screw driver, max. width of 4 mm, turn the screw on the adjustment worm (3) until
the switching point has been adjusted as desired. An extremely fine adjustment is possible
from both sides, without having to loosen the nut (5).
4. All adjustments must be looked at in an inspection round and checked for functionality.
5. Mount the cover of the GTES, see section 6.7.
