7 WHAT TO DO IF...
(troubleshooting guide)
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.
Solution
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).
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.
During the movement, the motors encountered excessive resistance; iden-
tify the cause and if necessary increase the level of force of the motors.
At the start of the manoeuvre or during the movement, the STOP input
was activated; identify the cause.
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.
Wait a few minutes until the manoeuvre limiting device falls to below the
maximum limit.
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.
Check the type of command that is always present; for example, it could
be a command from a timer on the "open" input.
Release the automation by giving the "Automation release" command.
Solution
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
Check the devices connected to the STOP input
STOP input active
S.S. input not active
Normal if the device connected to the S.S. input is active
OPEN input not active
Normal if the device connected to the OPEN input is active
The device self-learning process must be performed
(see paragraph 4.5)
Self-learning of the mechanical stop positions has not been performed
(see paragraph 4.6)
The ELS output has been with a function different from "electric lock" and
"courtesy light".
The inputs SS and OPEN have been assigned with a function different from
"Step Step" and "Partial Open 1" or "open" and "close".
The FLASH output has been assigned with a function different from "Fla-
shing Light" and "gate open indicator"
