FAULT FINDING
If you experiencing a problem please check through the following before making contact with NVC:
Fault - Load does not come on
1.Check to see if the live supply to the circuit is good.
2.If the supply & wiring are good, check the LUX setting. Increase the LUX level setting to allow the sensor to turn on at a higher ambient light level.
Fault - Lights do not go off
1.Ensure that the area is left unoccupied for longer than the selected timer setting.
2.Make sure that the sensor is not adjacent to circulating air, heaters or lamps.
3.Ensure luminaire is not connected in parallel with other luminaires containing sensors
