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

10.6.3 - Control unit
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
Table 13.

Action
At the beginning of the manoeuvre, the verification of the devices present does not
correspond to those learned; check and possibly try to redo the learning (10.3.3
"Recognition of other devices" ).
Some faulty devices may be present; check and replace them
At the start of the manoeuvre, one or more photocells are preventing movement;
check to see if there are any obstacles.
During the movement, although the obstacle is effectively present, no action is
required
During the movement, the gate experienced excessive friction; identify the cause.
At the start of or during the manoeuvre, 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 serious 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 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 "SbS" input
Release the automation by sending an automation release command to the con-
trol unit
Action
Make sure there is power supply; check to see if the fuses are blown; if nec-
essary, identify the reason for the failure and then replace the fuses ones of
the same type
There is a serious malfunction; try switching off the control unit for a few sec-
onds; if the condition persists, it means there is a malfunction and the circuit
board has to be replaced
Normal operation of control unit
gering of photocells or the radio transmitter is in use
All OK; when a command arrives, the control unit will reset to normal func-
tioning (after a brief delay)
An overload has been detected and therefore the power supply to the ECS-
bus has been turned off. Check, possibly 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
Action
Check the devices connected to the STOP input
STOP Input active
Action
SbS input not active
Normal only if the device connected to the SbS input is definitely active
