DIAGNOSTICS
Certain devices emit special signals showing the operating status or any malfunction.
9.1 - Warning light signals and courtesy light
During the manoeuvre the ashing light ashes once every second; when a fault occurs, the ashes become more frequent and are repeated
twice with a 1-second pause in between. The courtesy light emits the same diagnostics signals.

Signal Cause Solution
2 ashes
1-sec pause
2 ashes
Intervention of a photocell At the start of the manoeuvre, one or more photocells prevent movement; check whether
there are any obstacles.
This is normal when there is an obstacle hampering the closing movement.
3 ashes
1-sec pause
3 ashes
Activation of the “Motor Force”
limiting device
During the movement, the gate experienced excessive friction; identify the cause.
4 ashes
1-sec pause
4 ashes
Triggering of the STOP input
At the start of the manoeuvre or during the movement, the STOP input intervened; identify
the cause.
5 ashes
1-sec pause
5 ashes
Internal parameter memorisa-
tion error
Wait at least 30 seconds during which the control unit will attempt to restore the function.
If the condition persists, delete the memory and rerun the memorisation procedure.
6 ashes
1-sec pause
6 ashes
The maximum manoeuvre limit
per hour has been exceeded
Wait a few minutes until the manoeuvre limiting device drops below the maximum limit.
7 ashes
1-sec pause
7 ashes
Error in the internal electric
circuits
Disconnect all the power circuits for a few seconds and then try giving a command again;
if the condition persists it means there is a serious fault on the electronic board or the
motor cabling: perform the necessary checks and replace components, if necessary.
8 ashes
1-sec pause
8 ashes
Command already present. Another command is already present. Remove the command present to be able to send
other commands.
10 ashes
1-sec pause
10 ashes
Manoeuvre time-out or lack
of motor power during the posi-
tion recognition phase
The time-out denotes that the manoeuvre is too long. Shorten the manoeuvre time by
increasing the speed or balancing the gate to reduce the motor’s effort. If the motor lacks
power check whether the board is properly inserted in its housing
9.2 - Signals of LEDs on the control unit
The control unit contains LEDs that can emit
special signals both during normal operation
and in case of anomalies.
