Symptoms
The radio transmitter does not emit
any signal (the LED
[A] does not
light up)
The manoeuvre does not start and
the LED “ECSBbus”
[B] does not
flas
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 does not work
Probable cause and possible solution
• Check whether the batteries are flat and if necessary replace them (see paragraph 11.5)
• Make sure that the power cord is properly plugged into the mains outlet
• 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
• Make sure that the commands are actually received. If the command reaches the OPEN input, the corre-
sponding “OPEN” LED [D] must light up; if you are using the radio transmitter, the “ECSBus” LED must make
two long flashes.
• Make sure that the STOP input is active, i.e. that the “STOP” LED
[C] comes on. If this does not happen,
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 selected force is too low to move the gate. Check for obstructions and if necessary select a higher force
as described on page 15
• Make sure that there is voltage on the flashing light’s FLASH terminal during the manoeuvre (being intermit-
tent, the voltage value is not important: 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.
TABLE 10 (fig. 37)
10.5 - TROUBLESHOOTING
Table 10 gives possible indications on how to deal with malfunctions that
may be met during installation or due to a fault.
10.6 - DIAGNOSTICS AND SIGNALS
A few devices issue special signals that allow you to recognise the oper-
ating status or possible malfunctions.
10.6.1 - Photocells
The photocells contain a LED “SAFE” [A] ( fig. 38 ) that provides informa-
tion at any moment on the state of operation; see Table 11 .

STATUS
The photocell is not powered or is faulty
Device not recognised by the control unit
The RX receives a perfect 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
ACTION
Make sure that there is voltage (approx. 8-12 Vdc) on the pho-
tocell’s terminals; if the voltage is correct, the photocell is prob-
ably faulty
Repeat the recognition 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 you should check the TX-RX alignment
and make sure the glasses are clean
It is at the limit of normal operation, you should check the TX-
RX alignment and make sure the glasses are clean
Check to see if there is an obstacle between TX and RX. Make
sure that the LED on TX flashes once slowly. Check the TX-RX
alignment
