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 circulating air, heaters or
lamps.
If the unit “false triggers” reduce the sensitivity using the sensitivity
settings (see section 4 and 5).
