ENGLISH
The operator has two safety devices (5 , fig. 1) activated by the
front door. If either of the two safety devices are activated, the
operator is prevented from performing any operation.
As shown in Fig. 3, prepare the conduits and make the electrical
connections from the electronic control unit to the chosen
accessories.
Always route the power supply cables separately from the control
and safety cables (keyswitch, receiver, photocells, etc.). Use
separate conduits to avoid any interference.
6.
SETTING THE MECHANICAL CLUTCH
To calibrate the transmitted torque adjustment system, refer to
fig. 19.
1) Remove the self-locking nut using the key provided.
2) Remove the thrust ring and ring nut. Unscrew by two turns the
ring nut screwed onto the thrust ring.
3) Refit the ring and ring nut on the drive shaft. Tighten the self-
locking nut until it reaches the mechanical end stop.
4) Activate the system and check that the clutch is adjusted so
as to allow the leaf to move without danger.
5) If the clutch is not adjusted correctly, repeat steps 1), 2), 3)
and 4). To increase torque, slacken the ring nut inside the ring;
to reduce torque tighten the ring nut.
6) Once the clutch has been correctly adjusted, tighten the
lateral screw on the thrust ring. This way the thrust ring and the
ring nut are held firmly together, so if the leaf has to be moved
manually (section 8), it will not be necessary to readjust the
clutch in the event of an incorrect action.
N.B.: To ensure that the clutch is always adjusted in the same way,
tighten the self-locking nut until it reaches the mechanical end
stop.
7.
TESTING THE AUTOMATION
When installation is complete, affix the danger warning label to
the top of the casing (Fig. 20). Thoroughly check operation of the
automation and all connected accessories.
Give the customer the User's Guide. Explain how the gear motor
works and how it should be used correctly, and draw attention
to the potential danger zones of the automation.
8.
MANUAL OPERATION
If the gate has to be operated manually due to a power failure
or malfunction of the automation, use the release device as
follows.
-
Open the door in the casing using the triangular key provided
(see fig. 21).
-
When the door opens, a safety sensor (5, fig. 1) prevents the
electronic control unit from operating.
-
Using the key provided, undo the self-locking nut until the
clutch is released as shown in fig. 22.
-
Close the door and open or close the gate manually.
9.
RETURN TO NORMAL OPERATION
-
Turn off the power supply to the system.
-
Open the door in the casing using the triangular key provided
(see fig. 21).
-
Turn the self-locking nut shown in fig. 22 anticlockwise until it
reaches the mechanical end stop.
-
Close the door.
-
Turn the power supply to the system back on.
N.B.: To ensure that the clutch is always adjusted in the same way,
tighten the self-locking nut until it reaches the mechanical end
stop.
10. MAINTENANCE
When performing maintenance always check that the anti-
crushing clutch is correctly regulated and that the safety devices
operate correctly.
