6. Operating Instructions
The L 40 SC operates automatically based on its sensor settings and app configurations.
6.1 Motion Sensor Operation
The integrated passive infrared sensor detects heat emitted by moving objects (e.g., people, animals) within its detection zone. When motion is detected and the ambient light level is below the set twilight threshold, the light will activate.

- Permanent Light: Activate continuous illumination for a set period, overriding sensor control.
- Timer Function: Schedule specific on/off times or lighting scenarios.
- Learning Twilight: The sensor can learn the natural twilight levels of its environment for more accurate activation.
- Creep Guard: Provides additional detection directly below the sensor to prevent undetected approach.
