7.5) Connection to other devices
If the user needs to feed external devices such as a proximity read-
er for transponder cards or the illumination light of the key-operated
selector switch, it is possible to tap power as shown in Figure 23.
The power supply voltage is 24Vdc -30% - +50% with a maximum
available current of 100mA..
7.6) Troubleshooting
The table 20 contains instructions to help you solve malfunctions or
errors that may occur during the installation stage or in case of failure.
Table 20: Troubleshooting
Symptoms
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
The user is unable to command manoeuvres
and the "BLUEBUS" LED fails to 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 fol-
lowed 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
7.7) Diagnostics and Signals
A few devices issue special signals that allow you to recognize the
operating status or possible malfunctions.

Recommended checks
Check to see if the transmitter batteries are exhausted, if necessary replace them.
Check the transmitter has been memorised correctly in the radio receiver.
Check that ROBUS350 is being fed 230V voltage from the power supply. Check to see
if any fuses have blown. If necessary, identify the reason for the failure and then replace
the fuses with others having 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 force could be too low for this type of gate. Check to see whether there
are any obstacles; if necessary increase the force
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 10-30Vac); if there is volt-
age, the problem is due to the lamp; in this case replace the lamp with one having 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 S.C.A. output (Table 14). When the
light should be on, check there is voltage on the S.C.A. terminal (approximately
24Vdc). If there is voltage, then the problem will have been caused by the light, which
will have to be replaced with one with the same characteristics. If there is no voltage,
there may have been an overload on the S.C.A. output. Check that the cable has not
short-circuited.
