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:
x
z
y
Passage-way closed
-- Ensure that the equipment is powered off (main magneto-thermal circuit breaker disengaged).
-- Manually set the geared motor crank (24:1) to a distance of 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).
