The positioning of the limit switch cams will be correct if, when the arm stops in horizontal or vertical
position, the motor stops and the bolt (28:7
) is flush (without pressure) with the corresponding rubber
abutment (
28:5
) or (
28:6
).
Electrical closing test
Close or open the barrier arm electrically.
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 (
28:3
) or (
28:4
).
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 an complete opening/closing test.
6.
If necessary, repeat the above procedure until the
bolt (28:7
) is flush (without pressure) with the
corresponding rubber abutment (
28:5
) or (
28:6
), and never forget to first switch off the equipment!
b) If the movement stops TOO LATE, the rubber abutment is pushed in 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 (
28:3
) or (
28:4
).
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
bolt (28:7
) is flush (without pressure) with the
corresponding rubber abutment (
28:5
) or (
28:6
), 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 screw 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 screw will have to be flush (without pressure) with each abutment.
