5.7 – DIAGNOSTICS AND SIGNALS
A few devices issue special signals that allow you to recognise the operat-
ing status or possible malfunctions.
5.7.1 – Photocells
The photocells are equipped with a "SAFE" LED (Figure 91) that allows
you to check the operating status at any time.

1 very slow flash The RX receives a perfect signal
1 slow flash The RX receives a fair signal
1 quick flash The RX receives a poor signal
1 very quick flash The RX receives a very poor signal

5.7.2 – Flashing and courtesy lights
During the manoeuvre the flashing light flashes once every second, while
the courtesy light is always on; when something is wrong the flashes

Action
Make sure that there is voltage (approx. 8-12 V

faulty
Repeat the recognition procedure on the control unit.
Make sure that all the photocell pairs on BUS have correct
addresses

Normal operation but you should check the TX-RX alignment and
make sure the glasses are clean
It is at the limit of normal operation, you should check the TX-RX

Check to see if there is an obstacle between TX and RX. Make
sure that the LED on TX flashes once slowly. Check the TX-RX

are more frequent (half a second); the light flashes twice with a second's
pause between flashes. The diagnostic flashing itself is signalled by the
courtesy light.
Action
At the starting of the manoeuvre, the devices present do not cor-
respond to those recognised; check and if necessary try repeating
the recognition process. (5.3.3 "Recognition of Other Devices").
One or more devices may be faulty; check and, if necessary,
replace them.
At the start of the manoeuvre, one or more photocells do not
enable it; check to see if there are any obstacles.
If there is an obstacle impeding the movement no action is
required.
During the movement, the door experienced excessive friction;
identify the cause.
At the start of the manoeuvre or during the movement, the STOP
input was activated; identify the cause.
