7.6) Troubleshooting
The following table contains instructions to help you solve malfunc-
tions or errors that may occur during the installation stage or in case
of failure.

Table 21: 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
The radio transmitter does not control the
door and the LED on the transmitter lights up
No manoeuvre starts and the OK 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
followed by a reverse run
Check to see if the transmitter batteries are exhausted, if necessary replace them
Check to see if the transmitter has been memorised correctly in the radio receiver.
Check that the emission of the transmitters radio signal is correct by means of this empiri-
cal 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.
Check that SPIN is being fed 230 V voltage from the power 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 22.
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.
7.7) Diagnostics and Signals
A few devices issue special signals that allow you to recognize the
operating status or possible malfunctions.
7 flashes
1 second’s pause
7 flashes
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 closing movement.
7.7.1) Signalling with flashing light and courtesy light
During the manoeuvre the flashing light, if connected, flashes once every second. When something is wrong the flashes are more frequent;
the light flashes twice with a second’s pause between flashes. The courtesy light gives the same diagnostics signals.
Table 22: FLASH flashing light signalling
Quick flashes
Cause
ACTION
2 flashes
1 second’s pause
2 flashes
Triggering of a photocell
3 flashes
1 second’s 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’s pause
4 flashes
Activation of the STOP input
During the movement the STOP input was activated; identify the cause
5 flashes
1 second’s 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 electronic board has to be
replaced.
6 flashes
1 second’s 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.
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
electronic board or the motor cabling. Check and replace as necessary.
