8. Fault Finding
LOAD DOES NOT COME ON
Check to see if the live supply to the circuit is good.
Strap across the L and LIVE OUT (where used)
terminal to turn the load on.
If the supply and wiring are good, check the LUX
level setting. Increase the LUX level setting to
allow the controller to turn on at higher ambient
natural light level.
If the detection range is smaller than expected,
check the diagram above. Rotating the sensor
slightly may improve the range.
LIGHTS DO NOT GO OFF
Ensure that the area is left unoccupied for longer
than the selected timer setting.
Make sure that the sensor is not adjacent to circu-
lating air, heaters or lamps.
If the unit ―false triggers‖ reduce the sensitivity
using the sensitivity settings (see section 5 and 6).
