Status Meaning Possible solution
BlueBus LED
OFF 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 specications.
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 green ash per second Everything normal Normal control unit operation.
2 quick green ashes The status of the inputs has changed
This is normal when there is a change in one of the inputs: SbS, STOP,
OPEN, LIGHT, the photocells intervene or a command has been given
to the control unit.
A series of ashes
separated by a 1-second
pause
Various Refer to that shown in “Table 13”.
A series of quick and
extended red ashes
Short circuit on the BlueBUS terminal
clamp
Disconnect the terminal and verify the cause of the short-circuit on the
BlueBUS connections. If the short-circuit is resolved, the LED will start
ashing normally after about ten seconds.
STOP LED
OFF Intervention of the STOP input Check the devices connected to the STOP input.
On Everything normal STOP input active.
SbS LED
OFF Everything normal SbS input not active.
On Intervention of the SbS input
This is normal if the device connected to the SbS input is actually
active.
OPEN LED
OFF Everything normal OPEN input not active.
On Intervention of the OPEN input
This is normal if the device connected to the OPEN input is actually
active
LIGHT Led
OFF Everything normal LIGHT input not active.
On Intervention of the LIGHT input
This is normal if the device connected to the LIGHT input is actually
active.

Status Description
OFF Automation Stopped
Steady Lit Manoeuvre in progress
On 3 sec Automation Lock Command Executed
Flashes
The control unit must run the automatic force search procedure (refer to the “Learning of the door opening and
closing positions” paragraph). If the courtesy light ashes also during the manoeuvre, it means that a procedure is
under way to detect the critical points of the manoeuvre.
If it ashes synchronously with the warning light, there is an anomaly (refer to “Table 13”).
