Symptoms
The radio transmitter is not emit-
ting a signal (the LED [A] is not lit)
The manoeuvre does not start and
the LED "ECSBbus" [B] does not
flash
The manoeuvre does not start and
the flashing light is off
The manoeuvre does not start and
the flashing light flashes
The manoeuvre starts but is imme-
diately followed by an inversion
The manoeuvre is carried out but
the flashing light is not working

Probable cause and possible solution
• Check whether the batteries are flat and if necessary replace them (see the transmitter's instructions
manual)
• Check that the power supply cable is correctly inserted in the mains socket
• Check to see if the fuses [E] or [F] are blown; if necessary, identify the reason for the failure and then
replace the fuses with others of equal value
• 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 flashes
• Check that the STOP input is active, that is, the LED "STOP" [C] is lit. If this is not the case check the
device connected to the STOP input
• The photocells test which is carried out at the start of each manoeuvre has not given a positive result;
check them, referring also to compliance with 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 9.1.1
• During the manoeuvre, ensure that there is voltage on the FLASH terminal of the flashing light (as this is
intermittent, the voltage value is not significant: approximately 10-30 Vac); if there is voltage, the problem is
due to the lamp; in this case replace the lamp with one having the same characteristics

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
errors that may occur during the installation stage or in case of
failure.

9.6 - DIAGNOSTICS AND SIGNALS

Some devices directly provide particular signals to describe the state of
operation or eventually a malfunction.
9.6.1 - Photocells
In the photocells, there is a "SAFE" LED [A] (fig. 26) which allows you to
check the operating state at any time, see Table 11.
26
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 prob-
ably faulty
Repeat the recognition procedure on the control unit. Check
that all photocell pairs on the 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
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
