10.6.3 - Control unit
The LEDs on the control unit provide particular signals to report on the
normal operation and on possible faults; see Table 13.

STATUS
The photocell is not powered or it is faulty
Device not recognised by the control unit
The RX receives an excellent signal
The RX receives a good signal
The RX receives a poor signal
The RX receives a bad signal
The RX does not receive any signal

Serious fault
TABLE 11
ACTION
Check that the voltage on the photocell terminals is of about
8-12 Vdc; if the voltage is correct then the photocell is probably
faulty
Repeat the learning procedure on the control unit. Check that
all the photocell pairs on ECSBus have different addresses
(see Table 9)
Normal operation
Normal operation
Normal operation but check TX-RX alignment and correct cle-
aning of photocell lenses
At the limit of normal operation; check TX-RX alignment and
correct cleaning of photocell lenses
Check for any obstruction between TX and RX. Check that the
LED on the TX flashes slowly. Check TX-RX alignment
flashes 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
correspond 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 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.
Wait at least 30 seconds, and then try giving a command; if the
condition persists it means there is a serious fault and the electro-
nic board must be replaced.
Wait a few minutes until the manoeuvre limiting device falls to
below the maximum limit.
Disconnect all power circuits for a few seconds, and then try
giving a command; if the condition persists it means there is a
serious fault and the electronic board must 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.
Release the automation by giving to the control unit the release
automation command.
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 secon-
ds; if the status persists there is a fault and the electronic board
must be replaced.
