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 con-
dition persists it means there is a malfunction and the electronic board has to be replaced.
One flash every second Everything OK Normal operation of control unit.
2 Quick flashes The status of the inputs has
changed
This is normal when there is a change in one of the inputs: SbS, STOP, triggering of
photocells or the radio transmitter is used
