Error with safety limit switches 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.

Error with contactor 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.

Error in movement time-out 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.

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

WHAT TO DO IF…
(troubleshooting guide)
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 ashes 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).
