8.3 SIGNALLING THROUGH WARNING LIGHT
During the manoeuvre, the “FLASH” warning light ashes once every second; whenever anomalies occur, shorter ashes are emit-
ted; the ashes are repeated twice with a one-second pause in between.

Fast ashes Cause ACTION
1 ash
1-second pause
1 ash
BlueBus system error
At the start of the manoeuvre, the test to verify the devices
connected to the BLUEBUS does not provide the same devices
memorised during the learning phase. There may be defective
devices: check and replace them if necessary; if changes have
been made, the learning procedure must be repeated.
2 ashes
1-second pause
2 ashes
Intervention of a photocell
At the start of the manoeuvre, one or more photocells
are blocking the movement; check whether there are any
obstacles. During the manoeuvre, this is normal if an obstacle
is present.
3 ashes
1-second pause
3 ashes
Intervention of the “Motor Force” limiter
The gate encountered more resistance during its movement;
verify the cause and increase the motor force if necessary.
4 ashes
1-second pause
4 ashes
Intervention of the STOP input
At the start of the manoeuvre or during the movement, the
STOP input intervened; identify the cause.
5 ashes
1-second pause
5 ashes
Error in the internal parameters of the
control unit
Wait at least 30 seconds then try giving a command; if the
condition persists, it means that there is a serious malfunction
and the electronic board must be replaced.
6 ashes
1-second pause
6 ashes
The maximum number of manoeuvres per
hour limit has been exceeded
Wait a few minutes until the manoeuvre limiter drops below the
maximum limit.
7 ashes
1-second pause
7 ashes
Error in the internal electric circuits
Disconnect all power circuits for a few seconds then try giving
a command again; if the condition persists, it means that there
is a serious malfunction and the electronic board must be
replaced.
8 ashes
1-second pause
8 ashes
A command that prevents other
commands from being executed is
already present
Check the type of command that is always present; for
example, it could be a command from a timer on the “Open”
input.
9 ashes
1-second pause
9 ashes
The automation was stopped by a “Stop
automation” command
Unlock the automation mechanism by giving the “Unlock
automation” command.
8.4 SIGNALS ON THE CONTROL UNIT
The control unit has a series of LEDs, each of which can emit
special signals both during regular operation and when an
anomaly occurs.

Anomaly
Check for the presence of power; check that the fuses are not
blown; if necessary, identify the cause of the fault then replace
them with fuses having the same specications.
On
Serious anomaly
There is a serious anomaly; try switching off the control unit for
a few seconds; if the condition persists, it means that there is a
fault and the electronic circuit board must be replaced.
1 ash per second
Everything normal Normal control unit operation.

The status of the inputs has changed
This is normal when there is a change in the status of the STOP
or OPEN input, when the photocells activate or when the radio
transmitter is used.
