Setting the limit switches
The working time of the motor is controlled by mechanical limit
switches installed inside the rear box of the engine. The limit
switches work in pairs, the rst being the primary and
the second the safety one - green for the opening; red for the
closing.
Using the hoist, open a portion of the
gate to verify the direction of rotation
of the limit switches when opening.
When closing, the direction of rota-
tion will be the opposite.

Close the gate completely using
the push buttons (without forcing
the motor) or using the hoist.
Use the supplied key to loosen the
screws (interior hexagon) of the
paired limit switches (A).
Turn the pair of closing limit switches (red) in the direction
of closure until they activate the switches (B).
If they are a bit oseted, just turn until the rst switch is
activated.
Tighten the screws (interior hexagon) of the paired closing
limit switches (red) (C).
Open the gate completely using the push buttons (without
forcing the motor) or using the hoist.
Repeat steps 2 to 4 for the pair of opening limit switches
(green).
Within each limit switch there is a screw for ne-tuning (D).
Use it to set the oset between the two limit switches of
each pair - which should be minimal.
Open and close the gate using the push buttons to check
the tuning of the limit switches (don’t force the motor).
