Some devices are able to emit signals that serve to recognise their state of ope-
ration or possible faults.
If a flashing light is connected to the FLASH output on the control unit, it will
flash at intervals of 1 second during a manoeuvre. If faults occur, the flashing
light will emit a sequence of two shorter flashes separated by a 1 second pau-
se. Table 10 shows the cause and solution for each type of signal.
The LEDs on the control unit also emit signals. Table 11 shows the cause and
solution for each type of signal.
It is possible to verify faults that have occurred during the last 8 manoeuvres.
See Table 12.

LED Problem Solution
BLUEBUS
Always off
Always on
1 flash per second
2 quick flashes
Series of flashes separated by
one second pause
Fault
Serious fault
Everything normal
Input status variation
Various
Check that the control unit is powered. Check that the fuses have not
blown: if they have, check the cause of the fault and replace with others
with the same value
A serious fault has occurred: try disconnecting electrical power from the
control unit. If the problem persists it will be necessary to replace the elec-
tronic board
Control unit works correctly
Normal if one of the inputs (PP, STOP, OPEN, CLOSE) changes: photocells
activated or a command given via a transmitter
Refer to Table 10
STOP
Always off
Always on
Activation of the devices connected
to the STOP input
Everything normal
Check the devices connected to the STOP input
STOP input active
S.S.
Always off
Always on
Everything normal
S.S. input activation
S.S. input not active
Normal if the device connected to the S.S. input is active
OPEN
Always off
Always on
Everything normal
OPEN input activation
OPEN input not active
Normal if the device connected to the OPEN input is active
L1 - L2 Slow flashing Change in number of devices
connected to Bluebus or device
self-learning not performed
The device self-learning process must be performed
(see paragraph 4.6)
L3 - L4 Slow flashing Change in self-learning of the motor
types or the positions of the mechani-
cal stops
Self-learning of the mechanical stop positions has not been performed
(see paragraph 4.7)
L5 Slow flash All OK The ELS output has been with a function different from “electric lock” and
“courtesy light”.
L7 Slow flash All OK The inputs SS and OPEN have been assigned with a function different from
“Step Step” and “Partial Open 1” or “open” and “close”.
L8 Slow flash All OK The FLASH output has been assigned with a function different from “Fla-
shing Light” and “gate open indicator”
7 short flashes
1 second pause
7 short flashes
Electric circuits fault Wait at least 30 seconds, then try sending a command and if necessary
turn off the power supply. If the condition persists, there may be a malfun-
ction and the electronic board must be replaced.
8 short flashes
1 second pause
8 short flashes
A command is already present
that disables execution of other
commands
Check the type of command that is always present; for example, it could
be a command from a timer on the “open” input.
9 short flashes
1 second pause
9 short flashes
The automation has been blocked by
a “Block automation” command
Release the automation by giving the “Automation release” command.
TABLE 10 - Flashing light signals (FLASH)
Flashes Problem Solution
1 short flash
1 second pause
1 short flash
Bluebus system error At the start of the manoeuvre, the devices connected to Bluebus do not
correspond to those recognized during the self-learning phase. One or
more devices may be disconnected or faulty; check and, if necessary,
replace them. In case of modifications repeat the device self-learning pro-
cess (see paragraph 4.6).
2 short flashes
1 second pause
2 short flashes
Photocell activated One or more photocells do not enable movement or have caused a move-
ment inversion during travel; check to see if there are any obstructions.
3 short flashes
1 second pause
3 short flashes
Function activation
“Obstacle detection” by force limiter
During the movement, the motors encountered excessive resistance; iden-
tify the cause and if necessary increase the level of force of the motors.
4 short flashes
1 second pause
4 short flashes
STOP input activation At the start of the manoeuvre or during the movement, the STOP input
was activated; identify the cause.
5 short flashes
1 second pause
5 short flashes
Error on internal parameters in
control unit
Wait at least 30 seconds, then try giving a command and if necessary turn
off the power supply. If the condition persists, there may be a malfunction
and the electronic board must be replaced.
6 short flashes
1 second pause
6 short flashes
Maximum limit of consecutive mano-
euvres or manoeuvres per hour excee-
ded.
Wait a few minutes until the manoeuvre limiting device falls to below the
maximum limit.
