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 second's pause between flashes.

7.7.2) Signals on the control unit
On the ROBUS350 control unit there is a set of LED's each of whi-
ch can give special indications both during normal operation and in
case of malfunctions.

ACTION
At the starting of the manoeuvre, the devices connected to BLUEBUS do not
correspond to those recognized during the recognition phase. One or more
devices may be faulty; check and, if necessary, replace them; in case of modifi-
cations repeat the recognition process (7.3.4 Recognition of Other Devices).
At the starting 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 starting 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 drops to under the
maximum limit
Disconnect all the power circuits for a few seconds and then try to give the
command again. if the condition persists it means there is a serious malfunc-
tion 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 rea-
son for the failure and then replace the fuses with others having the same characteristics replaced
There is a serious malfunction; try switching off the control unit for a few seconds; if the condi-
tion 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
It corresponds to the flashing light's signal. See table n° 21.
ACTION
Check the devices connected to the STOP input
STOP Input active
ACTION
input not active
This is normal if the device connected to the STEP-BY-STEP input is actually active
ACTION
OPEN input not active
This is normal if the device connected to the OPEN input is actually active
ACTION
CLOSE input not active
This is normal if the device connected to the CLOSE input is actually active
