LED “SAFE”
Off
3 quick ashes and 1
second pause
1 very slow ash
1 slow ash
1 quick ash
1 very quick ash
Always lit
Status
The photocell is not powered or
it is faulty
Device not recognised by the
control unit
The RX receives an excellent
signal
The RX receives a good signal
The RX receives a poor signal
The RX receives a bad signal
The RX does not receive any
signal
Action
Check that the voltage on the photocell terminals is of about 8 ÷ 12 V
; if the voltage is correct then the photocell is probably faulty.
Repeat the learning procedure on the control unit (paragraph A.10).
Check that all the photocell pairs on BUS have different addresses
(see Paragraph A.9)
Normal operation
Normal operation
Normal operation but check TX-RX alignment and correct cleaning of
photocell lenses
At the limit of normal operation; check TX-RX alignment and correct
cleaning of photocell lenses
Check for any obstruction between TX and RX. Check that the LED
on the TX ashes slowly. Check alignment between TX and RX

Status
BUS error
Photocell activated
“Gearmotor force” limiting
device activated
STOP input activated
Action
At the beginning of the manoeuvre the devices present do not corre-
spond with those recognised; check and eventually carry out the lear-
ning procedure (paragraph A.10). 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
movement; check to see if there are any obstructions. During the
movement if there is an obstruction no action is required
During the movement, the leaf experienced excessive friction; identify
the cause
At the start of the manoeuvre or during the movement, the STOP input
was activated; identify the cause
Symptoms
The radio transmitter does not emit any
signal (the LED does not light up)
The manoeuvre does not start and the
BUS LED does not ash
The manoeuvre does not start and the
ashing light is off
The manoeuvre does not start and the
ashing light ashes
The manoeuvre starts but is immedia-
tely followed by an inversion
The manoeuvre is carried out but the
ashing light is not working
Probable cause and possible solution
• Check whether the batteries are discharged; replace if necessary.
• Check that the power supply cable is correctly inserted in the mains socket.
• Check that the fuses and have not been activated (paragraph A.3); if this is the case check the
cause of the fault and replace them with other fuses with the same characteristics.
• Check that the command is actually received. If the command reaches the SbS input the relevant
LED “SbS” should light up; if a radio transmitter is used the LED “BUS” should emit two long
ashes.
• See Table 14.
• The force selected is too low to move the leafs. Check for obstructions and if necessary select a
higher force as described in paragraph B.1
• During the manoeuvre, ensure that there is voltage on the FLASH terminal of the ashing light (as
this is intermittent, the voltage value is not signicant: approx. 10-30 V
); if voltage is present,
the problem is due to the lamp, which should be replaced with an identical version.
