normal operation and on possible faults; see Table 13.

Status

Everything OK
During a manoeuvre the fl ashing light fl ashes every second; in case of
anomalies the light fl ashes at more frequent intervals (half a second); the
fl ashes are repeated twice with an interval of one second; see Table 12.
TABLE 12
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 (10.3.3 "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
enable movement; check to see if there are any obstructions. Dur-
ing 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.
47
Action
Check that the unit is powered; check that the fuses have not
been activated; if this is the case check the cause of the fault
and replace them with other fuses with the same characteristics.
There is a serious fault; switch off the control unit for a few
seconds; if the status persists there is a fault and the electronic
board must be replaced.
Control unit works correctly
A variation to the status of the inputs: OPEN, STOP, activa-
tion of the photocells, or when the radio transmitter is used, is
normal.
Everything OK; when the control unit receives a command nor-
mal operation is restored (with a short delay).
An overload has been detected therefore the power to the
ECSBus switched off. Check by disconnecting the devices one
at a time.
To restore power to the ECSBus simply send a command, for
example with a radio transmitter.
Action
Check the devices connected to the STOP input
