7 TROUBLESHOOTING GUIDE
Some devices are configured for signalling the operating status or the presence of any anomalies.
7.1 SIGNALLING THROUGH WARNING LIGHT
If a warning light is connected to the FLASH output ( A ) on the
control unit, the light will flash once every 1 second while the
manoeuvre is being performed.
If any anomalies occur, the warning light will emit shorter flashes
which are repeated twice with a 1-second pause in between.
“ Table 9 ” describes the cause and possible solution for each
type of anomaly signalled by the warning light.

Flashes Anomaly Possible solution
1 short flash
1-second pause
1 short flash
BlueBus system error
The check to verify the devices connected to the BlueBus system,
run at the start of the manoeuvre, does not reveal the same devices
memorised during learning phase. There may be some disconnected
or faulty devices: check these and replace them if necessary. Some
changes were made: the device learning procedure must be rerun.
2 short flashes
1-second pause
2 short flashes
Intervention of a photocell
One or more photocells do not consent to the movement or have
caused the latter to reverse. Check for any obstacles.
3 short flashes
1-second pause
3 short flashes
Intervention of the
“Obstacle Detection”
function through the force
limiter
During the gate’s movement, the motors encountered more resistance.
Verify the cause and increase the motor force if necessary.
4 short flashes
1-second pause
4 short flashes
Intervention of the STOP
input
At the start of the manoeuvre or during the movement itself, the devices
connected to the STOP input intervened. Identify the cause.
5 short flashes
1-second pause
5 short flashes
Error in the internal
parameters of the control
unit
Wait at least 30 seconds then try giving a command and disconnect
the power supply if necessary. If the condition persists, there may be a
serious malfunction and the electronic board needs to be replaced.
6 short flashes
1-second pause
6 short flashes
The maximum limit for
consecutive manoeuvres or
manoeuvres per hour has
been exceeded
Wait for a few minutes until the manoeuvre limiting device drops to
under the maximum limit.
7 short flashes
1-second pause
7 short flashes
Electric circuit anomaly
Wait at least 30 seconds then try giving a command and disconnect
the power supply if necessary. If the condition persists, there may be a
serious malfunction and the electronic board needs to be replaced.
8 short flashes
1-second pause
8 short flashes
A command that prevents
other commands from being
executed is already present
Check the type of the “always present” command (for example, it could
be a command from a clock on the AUX input).
9 short flashes
1-second pause
9 short flashes
The automation was
stopped by a “Stop
automation” command
Unlock the automation mechanism by giving the “Unlock automation”
command.
10 short flashes
1-second pause
10 short flashes
Intervention of the
“Obstacle Detection”
function from the encoder
The motors were hampered by greater friction during their movement.
Identify the cause.
