8.1 NOTES FOR USERS
In the event of a blackout, release the operator by turning
the key clockwise, open the lever (Fig.12) and manually
open the gate.
Re-lock the operator, at the end of the operation, then
slide the gate slightly in one direction, until you hear a
coupling click.
Caution
At the end of a gate released
stage, in which manually opening or closing is possible
with the unit powered, it is necessary to move the gate
back to the closed position before using the unit again
(Step-by-Step START, remote control, etc.). If not, the
operator may not function correctly.
At regular intervals, we recommend carrying out
regular checks to ensure that the operator is running
smoothly. Do this at least once every 12 months.
8.2 NOTES FOR MAINTENANCE TECHNICIANS
Warning
Maintenance can only be carried out by specialised personnel. Before servicing the operator use the
differential switch to disconnect the power supply.
For correct maintenance regularly carry out the following checks as given in the maintenance manual issued
by the installer.
• Inspect the general condition of the gate structure and THE UPPER GUIDES.
• Inspect the condition of wheels, guide, couplings and limit stops.
• Inspect the condition of the safety device (photocells, ribs,.....) and performance of the electronic clutch.
• Check that the electric system and differential switch work correctly.
• Check that the input of the Stop push-button is connected to a NC contact and THAT IT IS WORKING CORRECTLY.
8.2.1 Troubleshooting
TYPE OF FAULT
The gate does not open when
commanded and the motor
does not start-up.
On giving the opening
command the motor
starts-up but the wing
does not move.
The gate opens in jerks, is
noisy or stops halfway.
On giving a closing command,
the gate does not close.
The key release offers strong
resistance or is blocked. On giving
the opening command the motor
starts-up but the gate does not move.
The gearmotor operates
slowly.

PLEASE, SUPPLY THIS PAGE TO THE USER
PROBABLE CAUSES
No power.
The circuit is not correctly connected.
The radio-controls are not working.
The equipment is not working.
The limit switch is not correctly connected or
is faulty.
The release is open.
Connection between motor and limit switch is inverted;
the motor is pushing the wing in the opposite direction.
Adjust the sensitivity of the electronic clutch.
The rack is resting on the pinion or the bar
pieces are not evenly spaced.
The guide has steps or the gate resists
movement.
The power of the gearmotor is insufficient for
the gate specifications.
The photocells are faulty.
The motor polarity is incorrect.
The gate comes to a halt against the limit stop
before it has been automatically stopped
causing on load blocking of the gears.
The gearmotor is in self-learning mode.

SOLUTIONS
Restore voltage.
Check that the equipment is correctly connected, that it has not
lost connection. The unused NC contact have to be jumpered.
Check that the radio-control battery is charged.
Check that the receiver is working.
Check the fuse F1.
Check the equipment logic.
Check that the limit switch is connected and working.
Check that input of the STOP push-button is connected
to a NC contact.
Shut the manual release.
Restore the correct limit switch connection.
Set torque adjustment (see enclosed manual).
Check the rack again and reset it to the correct horizontal
position.
Check the guide and wheels and improve sliding.
Use a more powerful gearmotor (see Par. TECHNICAL DATA).
Check photocells and relevant connections.
Reverse the jumper-lead positions (Reversing Motor).
Review the position of the plates and braking times.
Check correct working of limit stop.
Replace electronic equipment if the manual speed does
not restart properly.
