SAFETY CLUTCH ADJUSTMENT
Lift the cover of the box to reveal the adjuster screw of the mechanical clutch located on
top of the speed reducer casing (Fig. 14).
Remove the black protective cap, release the lock nut, and rotate the screw clockwise to
increase the force transmitted by the motor to the gate.
The adjustment should be made in such a way as to obtain a force marginally greater than
that effectively required to set the gate in motion.
N.B.: More force you set on the motor clutch, less reversibility you obtain from the
operator.

MAINTENANCE

To be undertaken by specialized staff after disconnecting power supply.
- Make certain that moving parts located inside the box are greased once a year, and check
the force transmitted through the drive to the gate.
- The motor should be overhauled every two years and the oil replaced. In the event that
the need for servicing or repairs should arise, the speed reducer can be removed from
the box without taking down the gate.
- Lift the cover from the box, isolate the motor from the power supply by disconnecting the
cable, then remove the curved lever: the gate can now swing freely.
- Thereafter, loosen the four nuts which secaure the fixing plate to the box and serve to
clamp the speed reducer in position (Fig.15-A/B).

ELECTRICAL SAFETY DEVICES

The installation must be installed according to the current regulations and laws. Use the T2
(for one or two single-phase motors) electronic control unit. For connections and technical
data of accessories refer to the appropriate booklets.
