5.3 - Special functions

5.3.1 - Function: "Move anyway"
This function allows the automation to be operated even when any of the safe-
ty devices does not work correctly or is out of use.
The automation can be controlled in the "hold-to-run" mode. Proceed as follows:
01. Send a command to operate the gate using a transmitter or a key selector,
etc. If everything operates correctly, the gate will move normally, otherwise
proceed as follows;
02. within 3 seconds, activate the control again and keep it activated;
03. after approximately 2 seconds, the gate will perform the required movement
in "hold-to-run" mode; i.e. the gate will continue to move only as long as
the control is activated.
If the safety devices do not operate, the flashing light flashes a few times to indi-
cate the kind of problem (see chapter 6 - Table 10).
5.3.2 - Function: "Maintenance warning"
This function serves to indicate when the automation requires maintenance.
The maintenance warning signal is given by way of a lamp connected to the
S.C.A. (open gate light) output when this output is programmed as "Mainte-
nance light". The various warning lamp signals are shown in Table 9.

(troubleshooting guide)
Some devices are able to emit signals that serve to recognise their state of
operation or possible faults.

5.4 - Deleting the memory
To delete the control unit memory and restore all factory settings, proceed as
follows:
press and hold keys " " and " " until leds L1 and L2 start flashing.
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
pause. 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 3.4).
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;
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 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.
During the movement, the motors have been blocked by higher friction;
identify the cause.
The type of fault that has occurred in
the last 8 manoeuvres can be establi-
shed
