1 ash
1 second’s pause
1 ash
Bluebus error At the starting of the manoeuvre, the devices connected to
BLUEBUS do not correspond to those recognized during the
recognition phase. One or more devices may be faulty; check
and, if necessary, replace them; in case of modications repeat
the recognition process.
2 ashes
1 second pause
2 ashes
Triggering of a photocell At the starting of the manoeuvre, one or more photocells do not
enable it; check to see if there are any obstacles. This is normal
when there is an obstacle impeding the movement.
3 ashes
1 second pause
3 ashes
Activation of the "motor force" limiting device During the movement, the gate experienced excessive friction;
identify the cause.
6 ashes
1 second pause
6 ashes
The maximum manoeuvre limit/hour has been exceed-
ed
Wait for a few minutes until the manoeuvre limiting device drops to
under the maximum limit.
7 ashes
1 second pause
7 ashes
There is an error in the internal electric circuits Disconnect all the power circuits for a few seconds and then try to
give the command again. if the condition persists it means there is
a serious malfunction and the electronic board has to be replaced
8 ashes
1 second pause
8 ashes
A command that does not permit other commands
to be performed 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.
4 ashes
1 second pause
4 ashes
Activation of the STOP input At the start of or during the manoeuvre, the STOP input was acti-
vated; identify the cause.
5 ashes
1 second pause
5 ashes
Error in the internal parameters of the electronic con-
trol unit
Wait at least 30 seconds, then try giving a command. if the con-
dition persists it means there is a malfunction and the electronic
board has to be replaced.
9 ashes
1 second pause
9 ashes
The automation mechanism has been stopped by a
“Stop automation mechanism” command
Release the automation mechanism by giving the “Release auto-
mation mechanism” command

BluebusLED Cause Solution
OFF Malfunction Check for presence of the power supply; check that the
fuses are not blown; in this case, identify the cause of
the fault and then replace with versions with the same
specications.
ON Serious malfunction There is a serious malfunction; try switching off the
control unit for a few seconds; if the condition persists, it
means there is a malfunction and the circuit board has to
be replaced.
1 ash per second All is OK Normal control unit operation
2 fast ashes There has been a change in the status of the inputs It is normal when there is a change to one of the inputs:
STOP, OPEN, triggering of photocells or the radio
transmitter is being used.
Series of flashes separated by a pause Various It is the same signal as for the flashing of 1 sec-
ond (see Table 20)
STOPLED Cause Solution
OFF Triggering or STOP input Check the devices connected to the STOP input
OFF All is OK STOP input is active
STEP-by-STEPLED Cause Solution
OFF All is OK STEP-by-STEP input is inactive
ON Triggering of STEP-by-STEP input Normal if the device connected to the S.S. input is active
OPENLED Cause Solution
OFF All is OK OPEN input is inactive
ON Triggering of OPEN input Normal if the device connected to the OPEN input is
active
CLOSELED Cause Solution
OFF All is OK CLOSE input is inactive
ON Triggering of CLOSE input Normal if the device connected to the CLOSE input is
active
10.4-Signalsonthecontrolunit
The SLIGHT unit has a series of LEDs, each of which can give particular signals
both during regular operation and when there is a problem. Refer to table 19,
table 20 and the gure shown here.
