To switch from more than one position simply wire two or more units in parallel to achieve two way and intermediate
switching.
The detector should be sited so that the occupants of the room fall inside the detection pattern shown overleaf, at a
recommended height of 1.2m to 1.5m for wall sensors. Note that the higher the sensor is installed the shorter the
detection range will be.
Do not site within 1m of any lighting or ventilation equipment.
Do not fix to a vibrating surface.
Site as far away as possible from the surface of metal objects.
Fault finding
What if the load does not turn ON?
Check to see if the live supply to the circuit is good. For the MWS1A-PRM version only: 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.
What if the load does not turn OFF?
Ensure that the area is left unoccupied for a greater time period than the time out period set using the switch.
Make sure that the sensor is not adjacent to vibrating surfaces or objects (e.g. ventilation equipment).
The unit may pick up movement through thin partitions or walls. Reduce the sensitivity.
