- Provide power and carry out some opening and closing
operations (see the starting instructions in the control panel
installation manual).
Adjust the limit switch bracket [17] so that the gate stops
approximately 20 mm before the opening and closing
stops.

-
Visually check that the gate, the fixing brackets and existing
structure have suitable mechanical strength and are in
good condition.
-
Check the gate-gearmotor alignment, the distance (2-3
mm) between the throat of the pinion and the crest of the
rack.
-
Clean the wheel’s sliding guide, the rack and pinion of the
gear motor and slightly lubricate the rack and pinion of the
