9.5 - TROUBLESHOOTING Table 10
contains instructions to help you solve malfunctions or
errors that may occur during the installation stage or in case of
failure.
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. 24
) which allows you to
check the operating state at any time, see Table 11 .

Symptoms Probable cause and possible solution
The radio transmitter is not emitting a signal (the
led
[A]
is not lit)
• Check to see if the batteries are spend. Replace if necessary (see paragraph 11.4)
The manoeuvre does not start and the led
“ECSBbus”
[B]
does not flash
• 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
No manoeuvre starts and the flashing light is off • Make sure that the commands are actually received. If the command is delivered to the
SbS
input the relative “ SbS ” led [D] must light up; otherwise if the radio transmitter is used, the “ ECS-
bus
” led flashes slowly twice
No manoeuvre starts and the flashing light
flashes a few times
• 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 manoeuvre starts but it is immediately fol-
lowed by a reverse run
• 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 paragraph 9.1.1)
The manoeuvre is carried out but the flasher
does not work
• Make sure that there is voltage on the flashing light’s FLASH terminal during the manoeuvre
(being intermittent, the voltage value is not important: approximately 10-30 Vac); if there is volt-
age, the problem is due to the lamp; in this case replace the lamp with one having the same
characteristics
TABLE 11
“SAFE” led [A] - fig. 24 Status Action
Off The photocell has no power supply
or is faulty 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.
3 quick flashes and 1 second
pause Device not recognised by control
unit Repeat the recognition procedure on the control unit. Check that all photocell
pairs on the ECSbus have different addresses (see
Table 8 )
1 very slow flash The RX is receiving optimum signal Normal operation
1 slow flash The RX is receiving good signal Normal operation
1 quick flash The RX is receiving poor signal Normal operation but it is necessary to check the TX-RX alignment and correct
cleaning of the glasses
1 very quick flash The RX is receiving bad signal It is at the limit of normal operation. It is necessary to check the TX-RX align-
ment and correct cleaning of the glasses
Always on The RX is receiving no signal Check for any obstruction between TX and RX. Check that the led on TX emits
a slow flashing. Check the TX-RX alignment
