EMERGENCY RELEASE
To be carried out after having disconnected the power supply to the motor.
In order to carry out the manual operation of the gate leaf the followings must be checked:
- That the gate is endowed with appropriate handles;
- That these appropriate handles are placed so to avoid safety risks for the operator;
- That the physical effort necessary to move the gate leaf should not be higher than 225
N, for doors/gates for private dwellings, and, 390 N for doors/gates for commercial and
industrial sites ( values indicated in 5.4.5 of the EN 12453 norm) .
In the case of a power cut, the gate can be opened manually by releasing the lock on the
operating lever to allow the gate to move freely (Fig. 8).
IMPORTANT: Please make sure that the leaves stop against the
mechanical stoppers inside the operator before
they reached the ground mechanical stopper. In not
adjusted, unblocking will be impossible.
SAFETY CLUTCH ADJUSTMENT
There is no mechanical safety clutch with the DUKE.
Therefore it is necessary to operate this operator with an electronic control panel fitted
with an electronic force regulator.
Use the T2 (for one or two single-phase motors) electronic control unit.
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.
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.
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.
- Then unscrew the for nuts that fix the motor.
