7.7.1) Flashing light signalling
During the manoeuvre the flashing light FLASH flashes once every second. When something is wrong the flashes are more frequent; the light
flashes twice with a pause of a second between flashes.

7.7.2) Signals on the control unit
On the RUN control unit there is a set of LED's each of which can
give special indications both during normal operation and in case of
malfunctions.

ACTION
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 faulty; check and, if necessary, replace them; in case of modifi-
cations repeat the self-learning process (7.3.4 Self-learning Other Devices).
At the start 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.
During the movement, the gate experienced excessive friction; identify the cause.
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. if the condition persists it
means there is a malfunction and the electronic board has to be replaced
Wait for a few minutes until the manoeuvre limiting device falls to below the
maximum limit
Disconnect all the power circuits for a few seconds and then try to give the com-
mand again. if the condition persists it means there is a serious malfunction and
the electronic board has to 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.

ACTION
Make sure there is power supply; check to see if the fuses are blown; if necessary, identify
the reason for the failure and then replace the fuses with others of the same characteristics
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 electronic board has to be replaced
Normal operation of control unit
This is normal when there is a change in one of the inputs: STEP-BY-STEP, STOP,
OPEN, CLOSE, triggering of photocells or the radio transmitter is used
Same signal as on flashing light. See table 21
ACTION
Check the devices connected to the STOP input
STOP input active
ACTION
S.S. input not active
Normal if the device connected to the S.S. input is effectively active
ACTION
OPEN input not active
Normal if the device connected to the OPEN input is effectively active
ACTION
Close input not active
Normal if the device connected to the CLOSE input is effectively active
