WHAT TO DO IF... (troubleshooting guide)
Some devices are designed to emit signals which help you recognise their
operating status or any problems.
If the WLT multi-purpose lamp is connected to the FLASH output on the power
supply and set with the flashing function, during the performance of a manoeu-
vre, it emits a flashing light every second. If any problems are encountered, the
flashing emits shorter flashes, which are repeated twice, divided by a 1 second

The recognition of the positions of the

pause. Table 10 describes the cause and solution for each type of signal.
The LEDs on the control unit also emit signals; Table 11 describes the cause
and solution for each type of signal.
Solution
The check of the devices connected to the Bluebus system, which is carried out at the
beginning of the manoeuvre, does not correspond to the devices stored during the
recognition phase. There might be devices which are disconnected or out of order, so
you need to check and replace them if necessary. If modifications have been made, you
will need to repeat the recognition of devices (see paragraph 4.7).
One or more photocells are not are not permitting movement or during travel they
caused the movement to be inverted; check for any obstacles.
During the movement, the motors encountered greater effort; verify the cause and
increase the force of the motors if necessary
At the beginning of the manoeuvre or during the movement, one of the devices connect-
ed to the STOP input was activated; verify the cause.
Wait at least 30 seconds and then try to repeat the command and if necessary cut off the
power supply; if the status remains the same, there might be a serious failure and the
electrical board may need replacing.
Wait a few minutes in order to allow the manoeuvres limiting device to return to below
the maximum limit.
Wait at least 30 seconds and then try to repeat the command and if necessary cut off
the power supply; if the status remains the same, there might be a serious failure and the
electrical board may need replacing.
Check the nature of the command in progress; it could for example be the command
from a clock on the "opens" input.
Release the automation system by sending the "Release the automation system" com-
mand.
Solution
Ensure the control unit is powered; check whether the fuses have blown.
In this case, check the cause of the fault and replace them with others of
the same value
There is a serious fault: try to cut off the electricity supply to the control unit
and if the status remains, then you will need to replace the electrical board
Normal operation of the control unit
If it normal if a variation in one of the input takes place (PP, STOP): pho-
tocells activation or a command is transmitted with a transmitter
Please refer to Table 10
Check the devices of the STOP input
STOP input activated
P.P. input deactivated
It is normal if the device connected to the P.P. input is activated
The recognition of devices must be carried out (see paragraph 4.7)
The recognition must be carried out (see paragraph 4.8).
