installation
The detector should be sited so that the occupants of the room fall inside the detection pattern
shown overleaf, at a recommended height of 2.8m on the ceiling. Note that the lower the sensor is
installed the smaller the detection range will be, subject to the parameters shown on the diagram.
Avoid direct sunlight entering the sensor.
Do not site within 1m of forced air heating
or ventilation.
Do not site within 1m of any lighting.
Do not fix to a vibrating surface.
Wire the product using the connector using the diagram on the front page.
Mount using one of the two options above.
To switch from more than one position simply wire two or more units in parallel.
Set the LUX level to maximum and the time to minimum.
Power the unit up—the load should come on immediately.
Vacate the room or remain very still and wait for the load to switch off (should take no more than 2
minutes).
Check that the load switches on when movement is detected.
To set the final LUX level wait until the level of natural daylight is just enough that lighting is re-
quired. Starting with the LUX control fully clockwise (at minimum), very slowly turn the control anti-
clockwise until the lights come on. Note that when the LUX control is at maximum then the lights
will always come on with occupancy.
Set the time required.
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 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.
