Troubleshooting
Table 13 contains instructions to help you solve malfunctions or errors that may occur during the installation stage or in case of failure.
Table 13 - Troubleshooting
Symptoms
Probable cause and possible solution
The radio transmitter does not control the door
and the LED on the transmitter does not light
up.
Check to see if the transmitter batteries are exhausted; if necessary, replace them.
The radio transmitter does not control the door
and the LED on the transmitter lights up.
Check to see if the transmitter has been memorised correctly in the radio receiver.
Check that the emission of the transmitter radio signal is correct by means of this empirical
test: push a key and rest the LED on the aerial of a normal radio (ideally an economical
one) that is switched on and tuned in, as close as possible, to 108.5Mhz FM; a slight
crackling sound should be heard.
No manoeuvre starts and the OK LED fails to
flash.
Check that OVO is being powered at the mains voltage of 230 V. Check to see if fuses
F1 and F2 (
fig. 46
) have blown; if necessary, identify the reason for the failure and then
replace the fuses with others that have the same current rating and specs.
No manoeuvre starts and the flashing light is off. 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.
No manoeuvre starts and the flashing light
flashes a few times.
Count the flashes and check the corresponding value in table 14.
The manoeuvre starts but it is immediately
followed by a reverse run.
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.

Diagnostics and signals
A few devices give out special signals that allow you to recognise the operating status or possible malfunctions.
8.1.1 - Flashing light and courtesy light signals
During the manoeuvre, the flashing light, flashes once every second if connected. When something is wrong, the flashes are more frequent:
the light flashes twice with a 1 second pause between flashes. The courtesy light gives the same diagnostics signals.
Table 14 - FLASH flashing light signals
Quick flashes
Cause
Action
2 flashes
1 second pause
2 flashes
Triggering of a photocell
At the start of the manoeuvre, one or more photocells are preventing
movement; check to see if there are any obstacles.
This is normal when there is an obstacle impeding the closing movement.
3 flashes
1 second pause
3 flashes
Activation of the "motor force"
limiting device
During the movement, the door experienced excessive friction; identify the
cause.
4 flashes
1 second pause
4 flashes
Activation of the STOP input
At the start of or during the manoeuvre, the STOP input was activated;
identify the cause.
5 flashes
1 second pause
5 flashes
Error in the internal parameters
of the electronic control unit
Wait at least 30 seconds, then try giving a command; if the condition
persists, it means there is a serious malfunction and the circuit board has to
be replaced.
6 flashes
1 second pause
6 flashes
The maximum manoeuvre limit/
hour has been exceeded
Wait for a few minutes until the manoeuvre limiting device drops to under the
maximum limit.
7 flashes
1 second pause
7 flashes
There is an error in the internal
electric circuits
Disconnect all the power circuits for a few seconds and then try giving a
command again; if the condition persists, it means there is a serious fault
on the circuit board or the motor cabling. Check and replace as necessary.
