8 TROUBLESHOOTING GUIDE
Some devices are congured for signalling the operating status or the presence of any anomalies.
8.1 SIGNALLING THROUGH WARNING LIGHT
If a warning light is connected to the FLASH output (A) on the
control unit, the light will ash once every 1 second while the
manoeuvre is being performed.
If any anomalies occur, the warning light will emit shorter ashes
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 red ash
1-second pause
1 short red ash
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 red ashes
1-second pause
2 short red ashes
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 red ashes
1-second pause
3 short red ashes
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 red ashes
1-second pause
4 short red ashes
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 red ashes
1-second pause
5 short red ashes
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 red ashes
1-second pause
6 short red ashes
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 red ashes
1-second pause
7 short red ashes
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 red ashes
1-second pause
8 short red ashes
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 red ashes
1-second pause
9 short red ashes
The automation was stopped by a
“Stop automation” command
Unlock the automation mechanism by giving the “Unlock
automation” command.
10 short red ashes
1-second pause
10 short red ashes
Intervention of the “Obstacle
Detection” function from the encoder
The motors were hampered by greater friction during their
movement. Identify the cause.
