Functions

1. On/ off Control
   This sensor is a motion switch, which turns on the light upon detection of motion,
   and turns off after a pre-selected hold-time when there is no IT’MJ\lement. A daylight sensor is also built in to prevent the light from switching on when there is sufficient natural light.

2. Lux Off Function
   The built-in daylight sensor can measure ambient natural light and switch off the fixture automatically whenever artificial light is not required (natural light lux level exceeds daylight tr, used.

3. Manual Override
   With the help of push-switch, this sensor can be over-lidden by the end-user to manually switch on/off the light, which makes the product more user- friendly and offers more opbons to fit some extra-ordinary demands:

• Short Push (<1s): on/off function;
  • On—-}, Off: the light turns off immediately and cannot be triggered ON by motion until the expiration  of the pre-set hold-time. After this peliod, the sensor goes back to normal sensor mode.
  • Off—-}, On: the light turns on and goes to sensor mode, no matter if ambient Lux level exceeds the daylight thresl”M:Jld or not.

Note: if end-user do not want this manual override function, just leave the ·push’ terminal unconnected to any wire.

Semi-auto Mode (Absence Detection)
It is easy to forget to switch off the light, in office, corridor, even at home. And in many other cases, people do not want to have a sensor to switch on the light automatically, for example, when people just quickly pass-by, there is no need to have the light on. The solution is to apply this “absence detector’: motion sensor is employed, but only activated on the manual press of the push-switch, the light keeps being ON in the presence, and switches off in the long absence.

Note: end-user can choose either flllction 3.3 or function 3.4 for application.
Default function is manual override.

Zero-cross Relay Operation
Designed in the software, sensor switches on/off the load right at the zero- cross point, to ensure that the in-rush current is minimised, enabling the maximum lifetime of the relay.
