4. Behaviour on switching on
Whenever the sensor module is plugged onto the power module or the unit
is energised, the detector goes through tree phases which are indicated by
an LED.
1. Start-up phase (30sec)
LED flashes every second, both contacts are closed
(light and presence on)
In case of absence, both contacts open after 30sec.
2. Service phase (10min)
The «Light» contact reacts instantaneously on brightness in order to
check the brightness threshold.
If the brightness is insufficient the lighting is switched on (LED on),and if
the brightness is sufficient the lighting is switched off (LED off).
During the service phase, switching of the lighting occurs fully automati-
cally (no semi-automatic mode).
The service phase terminates earlier by actuating the push-button or the
remote control.
3. Operation
The detector is ready for operation (LED off).
