7.7.2) Signals on the control unit
On the SPIN control unit there is a set of LED’s each of which can
give special indications both during normal operation and in case of
malfunctions.
Table 23: LED’s on the control unit’s terminals
Malfunction
Make sure there is power supply; check to see if the fuses are blown; if
necessary, identify the reason for the failure and then replace the fuses with
others having the same characteristics.
On Serious malfunction
There is a serious malfunction; try switching off the control unit for a few
seconds; if the condition persists it means there is a malfunction and the
electronic board has to be replaced.

This is normal when there is a change in one of the inputs: Step-by-Step,
STOP, triggering of photocells or the radio transmitter is used

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.
