7.6) Troubleshooting
The table 19 contains instructions to help you solve malfunctions or
errors that may occur during the installation stage or in case of fail-
ure.
Table 19: Troubleshooting
Symptoms
The radio transmitter does not control the
door and the LED on the transmitter does
not light up
The radio transmitter does not control the
door and the LED on the transmitter lights
up.
No manoeuvre starts and the OK 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
7.7) Diagnostics and signals
A few devices issue special signals that allow you to recognize the
operating status or possible malfunctions.
7.7.1) Flashing light signalling
During the manoeuvre the flashing light flashes once every second. When something is wrong the flashes are more frequent; the light flash-
es twice with a 1 second pause between flashes..

Probable cause and possible solution
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 the correct emission of the transmitter radio signals with the following empirical test:
push the button and rest the LED against the aerial of a normal household radio (ideally
inexpensive) that is switched on and tuned in at 108.5 Mhz FM or as close as possible; a
low sound should be heard with crackling pulses.
Check that ROAD200 is powered by a 230V mains supply. Check to see if the fuses F1
and F2 are 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 OK LED flashes twice indicating that the command has been received.
Count the flashes and check the corresponding value in table 20.
The selected force could be too low for this type of door. Check to see whether there are
any obstacles; if necessary increase the force.
ACTION
At the starting of the manoeuvre, one or more photocells do not enable it;
check to see if there are any obstacles.
This is normal when there is an obstacle impeding the movement.
During the movement, the door experienced excessive friction; identify the
cause.
At the starting of the manoeuvre or during the movement ,the STOP input was
activated; identify the cause
Wait at least 30 seconds, then try giving a command. If nothing happens there
may be a serious fault and the electronic card will have to be replaced.
Wait for a few minutes until the manoeuvre limiting device drops to under the
maximum limit.
Disconnect all the power circuits for a few seconds and then try to give the
command again. If nothing happens there may be a serious electronic card or
motor cabling fault. Carry out a control and possible replacement.
