Problem
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 process (see paragraph 3.4).
One or more photocells do not enable movement or have caused a movement inversion during travel; check
to see if there are any obstructions.
During the movement, the motors encountered excessive resistance; identify 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 malfunction 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 electronic board.
Control unit works correctly.
Normal if one of the inputs (PP, STOP, OPEN, CLOSE) changes: photocells acti-
vated or a command given via a transmitter.
Refer to Table 10.
Check the devices connected to the STOP input.
STOP input active.
P.P. input not active.
Normal if the device connected to the P.P. input is active.
OPEN input not active.
Normal if the device connected to the OPEN input is active.
CLOSE input not active.
Normal if the device connected to the CLOSE input is active.
The device self-learning process must be performed (see paragraph 3.5).
Self-learning of the mechanical stop positions has not been performed.
