Manual Lux Sensor for daylight control

Usage

The PIR sensor has been designed to switch 
lighting, heating and ventilation loads up
to 6A. The unit is switched on by the 
detection of moving infra red heat within
a specified range. When infra red heat, such 
as a moving body, is no longer detected,
the unit will switch off the load after the 
adjustable time period has elapsed. 

If infra red heat is detected again during the 
timing period, the timing sequence will 
restart. The unit has a lux level adjustment 
which measures the ambient light levels 

and prevents lighting being switched on, 
when there is sufficient lighting in the room.

A power factor correction capacitor of 4 
microfarads may be required when
switching low wattage loads, e.g. LED loads. 
The capacitor is fitted across switch live 
and neutral supplies of suitable Elkay 
capacitors can be found at your stockist 
(ref. pfcc-1).

Do not insulation resistance test this 
product. Remove before testing or test
circuit prior to fitting.
