a) If the movement stops TOO EARLY, without being flush with the rubber abutment:
1. Switch off the circuit breaker (4:1).
2. Loosen the fixing screw of the cam to be set (20:3) or (20:4).
3. Move the cam slightly in the direction opposite the movement in order to delay the stop of the
mechanism.
4. Switch on the equipment again.
5. Make a complete opening/closing test.
6. If necessary, repeat the above procedure until the crankshaft plate is flush (without pressure)
with the corresponding abutment (19:1) or (19:2), and never forget to first switch off the
equipment!
b) If the movement stops TOO LATE, thrust against the abutment or the motor goes on running:
1. Switch off the circuit breaker (4:1).
2. Loosen the fixing screw of the cam to be set (20:3) or (20:4).
3. Move the cam slightly in the direction of the movement in order to anticipate the stop of the
mechanism.
4. Switch on the circuit breaker (4:1).
5. Make a complete opening/closing test.
6. If necessary, repeat the above procedure until the crankshaft plate is flush (without pressure)
with the corresponding rubber abutment (19:1) or (19:2), and never forget to first switch off the
equipment!

At the beginning of the use on site, the position of the limit switches is such that the crankshaft plate may
stop at 2 to 3mm from each abutment at the end of the movement. However, after about 1000 operations,
the mechanism will be ran in and this plate will have to be flush (without pressure) with each abutment.
