Cam setting
The barrier is equipped with 2 mechanical sensors coming into contact with cams.
These limit switches and cams are accessible after removing the cover.

sensor (not shown in the images below) and then the closing sensor).
It is the adjustment of the cams which allows the horizontal and vertical adjustment of
the arm. To adjust it, you have to screw/unscrew the corresponding cam to make it
detected earlier or later in the movement of the arm. You have to use the allen wrench
attached on the redactor.

cams.
The axis of the limit switches must go to the center of the cam.
