8.1. Limit switch cam adjustment
•
The obstacle is closed in the “0 position” if the points (
x
), (
y
), and (
z
) of the crankshaft-rod device are
perfectly aligned as illustrated in Fig. 24. If the factory-set alignment of these points is correct, the obstacle in
open position (i.e., with passage-way closed) must be locked, with a minimum play, and with motor stopped.
To correct the limit switch cam, proceed as follows:
24:1 Geared motor crank
24:2 Limit switch cam

40 mm
from the closing abutment (lower
rubber bumper).

Loosen the two locking screws of the cam (
24:2
), and slightly move the cam in either direction until the
limit switch is engaged (a click sound can then be heard).
