7.7) Diagnostics and signals
A few devices issue special signals that enable identification of operating status or possible malfunctions.
7.6) Troubleshooting
Table 19 contains instructions to help solving malfunctions or errors
that may occur during the installation stage or in case of failure.

Recommended checks
The radio transmitter does not control the gate
and the LED on the transmitter does not light up.
The radio transmitter does not control the gate
but the LED on the transmitter lights up
No manoeuvre starts and the “BlueBUS” LED
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 immediately
followed by a reverse run
The manoeuvre is carried out but the flashing
light does not work
The manoeuvre is carried out but the Open
Gate Indicator does not work
Check to see if the transmitter batteries are discharged, if necessary replace them
Check to see if the transmitter has been memorised correctly in the radio receiver
Check that RUN is powered by a 230V mains supply.
Check to see if the fuses are blown; if necessary, locate the reason for the failure and
then replace the fuses with others of the same current rating and characteristics.
Make sure that the command is actually received. If the command reaches the STEP-
BY-STEP input, the corresponding “STEP-BY-STEP” LED must light up; if you are using
the radio transmitter, the “BlueBus” LED must make two quick flashes.
Count the flashes and check the corresponding value in table 21
The selected level of obstacle detection sensitivity could be too high for the type of gate.
Check to see whether there are any obstacles; if necessary select a lower level of sensitivity.
Make sure that there is voltage on the flashing light's FLASH terminal during the manoeu-
vre (being intermittent, the voltage value is not important: approximately 10-30Vdc); if
there is voltage, the problem is due to the lamp; in this case replace the lamp with one
of the same characteristics; if there is no voltage, there may have been an overload on
the FLASH output. Check that the cable has not short-circuited.
Check the type of function programmed for the Gate Open indicator output (L4 on table
9). When the indicator should be lit, check that there is voltage on the Open Gate Indi-
cator terminal (approx. 24 Vdc); if voltage is present the problem is caused by the light,
which will have to be replaced with one with the same characteristics. If there is no volt-
age, there may have been an overload on the open gate indicator output.Check that the
cable has not short-circuited.

Wait for about 3s after which the LEDs corresponding to the manoeuvres in which the defect occurred
will light. The L1 LED indicates the result of the last manoeuvre and L8 indicates the result of the 8th
manoeuvre. If the LED is on, this means that a defect occurred during that manoeuvre; if the LED is off,
this means that no defect occurred during that manoeuvre.

RUN enables the user to view the possible malfunctions that have occurred in the last 8 manoeuvres; for example, the interruption of a
manoeuvre due to a photocell or sensitive edge cutting in. To verify the malfunctions list, proceed as in table 20.
