Wire Preparation
Pluggable screw terminal. It is recommended to make
connections to the terminal before fitting to the sensor.
3. Functions
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 movement. A daylight sensor is
also built in to prevent the light from switching on when there is sufficient natural light.
Manual Override
With the help of push-switch, this sensor can be over-ridden by the end-user to manually switch
on/off the light, which makes the product more user-friendly and offers more options to fit some
extra-ordinary demands:
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 function 3.3 or function 3.4 for application.
Default function is manual override.
Semi-auto Mode (Absence Detection)
3.4
3.3
3.1
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
threshold).
Lux Off Function
3.2
* Short Push (<1s): on/off function;
On
→
Off: the light turns off immediately and cannot be triggered ON by motion until the expiration
of pre-set hold-time. After this period, 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 threshold or not.
Note: if end-user do not want this manual override function, just leave the “push” terminal
unconnected to any wire.
zero-cross point
Alternating current
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.
