Manoeuvre time-out or lack of
motor power during the position
recognition phase
The time-out denotes that the manoeuvre is too long. Shorten the manoeuvre time by
increasing the speed or balancing the gate to reduce the motor’s effort. If the motor
lacks power check whether the board is properly inserted in its housing
9.2 - Signals of LEDs on the control unit
The control unit contains LEDs that can emit

OK LED Cause Solution
Red and green LED off Fault Make sure there is power supply; check to see whether the fuses are blown;
if necessary, identify the reason for the failure then replace them with others
of the same type.
Green or red LED on Serious fault Try switching off the control unit for a few seconds; if the condition persists,
it means that there is a malfunction and the electronic circuit board has to
be replaced.
1 green ash per second All OK Normal control unit operation.
2 quick green ashes Input status variation This is normal when there is a change in one of the inputs: SbS, STOP, inter-
vention of photocells or the radio transmitter is used.

Off During normal operation it indicates “Short slowdown”
On During normal operation it indicates “Long slowdown”
Flashes Function programming in progress
L2 Description
OFF During normal operation it indicates slow “Motor speed”
On During normal operation it indicates fast “Motor speed”
Flashes - Function programming in progress
- If it ashes together with LEDs L1 and L3, the user must run the recognition phase of the gate opening
and closing positions (Paragraph 7.3).
L3 Description
OFF During normal operation the device indicates “Automatic Closing” is inactive.
On During normal operation the device indicates “Automatic Closing” is active.

- If it ashes together with LEDs L1 and L2, the user must run the recognition phase of the gate opening
and closing positions (Paragraph 7.3).
L4(R) (radio) Description
On During normal operation it indicates that a radio code not present in the memory has been received.
