Output 1 (for lighting loads, connected to terminals L’ and N)
This output operates in exactly the same way as the output in the single-load
sensor unit and switches the connected load when:
• Motion is detected by the user-selected combination of PIR and Ultrasonic
sensors.
• The ambient light level is below the set light level adjustment.
Output 1 uses TIME 1 adjustment to set the switch-off time delay. The time
adjustment can be set for delays from 5sec to 30min.
The 1sec Pulse and Test
settings are used during setup. Refer to Setup and Operation.
Only if left in test mode
