Note - The diagnostic signals provided by flashing leds stop when the control unit is given a command.
By using an external flashing light*, the diagnostics signals continue for two sequences of flashes (e.g. "3 flashes – short pause – 3 flashes –long
pause" repeated twice).
IMPORTANT: To connect the external flashing light, you need to use the additional NDA040 board (not supplied).
* Configured with the Oview programmer as "Flashing Light 1"

WHAT TO DO IF...
The following is a list of possible malfunctions that may occur during installation or due to a failure, together with the possible solutions:
• The motor is at a standstill, no manoeuvre is commanded and the red LED flashes: verify the type of flashing by checking the L1 LED Diagnostics
table (paragraph 10.2) and press the red STOP button to cancel the diagnostics.
• The radio transmitter does not control movements and the LED on the transmitter does not come ON: check to see if the transmitter batteries
have run down and replace them, if necessary.
• The radio transmitter does not control movements but the LED on the transmitter comes ON: check to see if the transmitter is correctly saved
on the radio receiver. Also, check that the transmitter sends its radio signals correctly, by performing the following empirical test: press any button on the
transmitter and place its LED on the aerial of any ordinary radio that is ON and tuned to 108.5 Mhz (or close to it) on the FM band; in this way, you should
hear a slight noise with crackling pulses.
• When a command is sent, no manoeuvre takes place and the OK LED does not flash: check that the control unit is connected to mains supply
with voltage of 230/400V. Also, check that the fuses have not blown; if they have, identify the cause of the failure and then replace them with others of the
same type.
• When a command is sent, no manoeuvre takes place and the flashing light is OFF: check that the command is actually received; if the command
reaches the SS input, the OK LED flashes twice to indicate that the command has been received.
• The manoeuvre fails to start and the flashing light flashes a few times: count the number of flashes and check the meaning of the flashes with the
diagnostics table in paragraph 10.2
• The motor turns in the opposite direction:
- for a three-phase motor, you need to invert the "V" and "W" phases of the motor
- for a single-phase motor, you need to invert the "V" and "W" phases of the motor
• The manoeuvre starts but stops shortly after: identify the cause using the diagnostics of the Leds on the control unit.
• The red WARNING L1 led flashes 9 times followed by a pause: there was an error in the recognition procedure of the Opening and Closing positions.
You must delete the memory (see 7.9) and repeat the position recognition procedure (see 7.10).

The gate has gone past the safety limit switches during Opening
or Closing. Move the gate manually to about half way up using the
emergency manoeuvre system (see the manual of the motor) and
press the STOP button on the cover in order to restore operation.
Assess whether you need to change the previously acquired Open-
ing/Closing positions.
Disconnect all the power lines for a few seconds, then try sending a
command again; if the problem persists, there may be a serious fault
on the circuit board or on the connections of the motor. Carry out
checks and replace parts, if required.
Check that the motor-control unit cable is connected correctly, in
particular the encoder cable (6 coloured wires).
Check that the motor-control unit cable is connected correctly, in
particular the encoder cable (6 coloured wires). Rerun the recogni-
tion procedure of the Opening and Closing positions.
Repeat the recognition procedure of the Opening and Closing posi-
tions.
The default setting for the movement time-out is 60 seconds. Check
whether there are any obstructions to the movement of the gate
or whether the gate has actually performed the movement. Check
whether the duration of the timer has been changed (using the
Oview programmer if available). Repeat the recognition of the Open-
ing and Closing positions.

The safety chain is made up of the series of inputs (ALT, Stop via button, motor
thermal protection, motor release). Close the circuit
