During the manoeuvre the flashing indicator flashes once every second.
When something is wrong the flashes are more frequent (every half sec-

The control unit has a series of LEDs, each of which can give particular
signals both during regular operation and when there is a problem, see

Action
At the beginning of the manoeuvre the devices present do not cor-
respond with those recognised; check and eventually carry out the
learning procedure (9.3.3 "Recognition of other devices"). One or
more devices may be faulty; check and, if necessary, replace them.
At the start of the manoeuvre, one or more photocells do not ena-
ble movement; check to see if there are any obstructions. During
the movement if there is an obstruction no action is required.
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.

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 them with others of the same type
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 circuit board has to be replaced
Control unit works correctly
This is normal when there is a change in one of the inputs: OPEN,
STOP, triggering of photocells or the radio transmitter is used
All OK; when a command arrives, the control unit will reset to
normal functioning (after a brief delay)
An overload has been detected therefore the power to the ECS-
Bus switched off. Check, if necessary, by disconnecting each
device one at a time.
To switch on power to the ECSBus you simply need to give the
command, for example, using the radio transmitter
