10.5 - TROUBLESHOOTING
Symptoms
The radio transmitter does not
emit any signal (the LED [A] does
not light up)
The manoeuvre does not start and
the LED "ECSBus" [B] does not
fl ash
The manoeuvre does not start and
the fl ashing light is off
The manoeuvre does not start and
the fl ashing light fl ashes
The manoeuvre starts but is imme-
diately followed by an inversion
The manoeuvre is carried out but
the fl ashing light is not working

10.6 - DIAGNOSTICS AND SIGNALS
Some devices directly provide particular signals to describe the state of
operation or eventually a malfunction.
10.6.1 - Photocells
The photocells contain a LED "SAFE" [A] (fi g. 46) that provides informa-
tion at any moment on the state of operation; see Table 11.
LED "SAFE"
Off
3 quick fl ashes and 1 second
pause
1 very slow fl ash
1 slow fl ash
1 quick fl ash
1 very quick fl ash
Always lit

TABLE 10 (fi g. 45)
Probable cause and possible solution
• Check whether the batteries are fl at and if necessary replace them (see paragraph 11.5)
• Check that the power supply cable is correctly inserted in the mains socket
• Check that the fuses [E] and [F] 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
• Check that the command is actually received. If the command reaches the OPEN input the relevant LED
"OPEN" [D] should light up; if a radio transmitter is used the LED "ECSBus" should emit two long fl ashes
• Check that the STOP input is active, in other words that the LED "STOP" [C] is on. If this is not the case
check the device connected to the STOP input
• The photocell test carried out at the beginning of each manoeuvre is negative; check the photocells and
refer to Table 11
• The force selected is too low to move the gate. Check for obstructions and if necessary select a higher
force as described in paragraph 10.1.1
• During the manoeuvre, ensure that there is voltage on the FLASH terminal of the fl ashing light (as this is
intermittent, the voltage value is not signifi cant

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
Table 10 gives possible indications on how to deal with malfunctions that
may be met during installation or due to a 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 8)
Normal operation
Normal operation
Normal operation but check TX-RX alignment and correct cleaning
of photocell lenses
At the limit of normal operation; check TX-RX alignment and cor-
rect cleaning of photocell lenses
Check for any obstruction between TX and RX. Check that the
LED on the TX fl ashes slowly. Check TX-RX alignment
