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
No manoeuvre starts and the
flashing light is off
No manoeuvre starts and the
flashing light flashes a few times
The manoeuvre starts but it is imme-
diately followed by a reverse run
The manoeuvre is carried out but
the flasher does not work
Probable cause and possible solution
• Check to see if the batteries are spend. Replace if necessary (see paragraph 11.5)
• Make sure that the power supply cable is properly inserted into the electrical network 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
• Make sure that the commands are actually received. If the command is delivered to the OPEN input the
relative “OPEN” LED [D] must light up; otherwise if the radio transmitter is used, the “ECSBus” LED flashes
slowly twice
• Check that the STOP input is active, that is, the LED “STOP”
[C]
is lit. If this does not happen, 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 selected force could be too low for this type of gate. Check to see whether there are any obstacles;
if necessary increase the force as described on page 15
• Make sure that there is voltage on the flashing light’s FLASH terminal during the manoeuvre (being inter-
mittent, 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

10.5 - TROUBLESHOOTING
Table 10
contains instructions to help you solve malfunctions or errors
that may occur during the installation stage or in case of failure.
10.6 - DIAGNOSTICS AND SIGNALS
A few devices give out special signals that allow you to recognise the
operating status or possible malfunctions.
10.6.1 - Photocells
In the photocells, there is a “SAFE” LED
[A]
(
fig. 40
) which allows you to
check the operating state at any time, see
Table 11
.

STATUS
The photocell has no power supply or is
faulty
Device not recognised by control unit
The RX is receiving optimum signal
The RX is receiving good signal
The RX is receiving poor signal
The RX is receiving bad signal
The RX is receiving no signal
ACTION
Check that on the terminals of the photocell there is a voltage of
approximately 8-12 Vdc; if the voltage is correct, it is likely that
the photocell is 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 it is necessary to check the TX-RX align-
ment and correct cleaning of the glasses
It is at the limit of normal operation. It is necessary to check the
TX-RX alignment and correct cleaning of the glasses
Check for any obstruction between TX and RX. Check that the
LED on TX emits a slow flashing. Check the TX-RX alignment
