5. Operating Instructions
5.1 Motion Sensor Settings
The motion sensor has three adjustable controls: SENS (Sensitivity), TIME (Duration), and LUX (Light Sensitivity).

Image 6: Close-up of the motion sensor's adjustable controls.
- SENS (Sensitivity): Adjusts the detection range of the PIR sensor from 1 m to 10 m. Turn clockwise to increase sensitivity, counter-clockwise to decrease.
- TIME (Duration): Sets how long the light remains on after motion is detected. Adjustable from 5 seconds to 600 seconds (10 minutes). Turn clockwise for longer duration, counter-clockwise for shorter.
- LUX (Light Sensitivity): Determines the ambient light level at which the sensor becomes active.
- Turn towards the "sun" icon for detection during both day and night (5 - 2000 lx).
- Turn towards the "moon" icon for detection only at night (5 lx).
5.2 ON/OFF Switch
An integrated ON/OFF switch allows you to disable the motion detector and use the projector as a standard floodlight, providing continuous illumination regardless of motion.
6. Maintenance
- Cleaning: Clean the projector and sensor regularly with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the mounting and electrical connections for any signs of wear, damage, or loosening.
- Bulb Replacement: The LED light source is integrated and not user-replaceable. If the LEDs fail, the entire unit should be replaced.
- Environmental Protection: Dispose of the product responsibly at the end of its lifespan according to local regulations for electronic waste.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply; LUX setting too low (daylight); Motion not detected; Faulty sensor/LED. | Check power connection; Adjust LUX setting towards "sun" icon; Verify motion in detection zone; Contact support if problem persists. |
| Light stays on continuously. | Motion detector switched off; Continuous motion in detection zone; Faulty sensor. | Check ON/OFF switch; Reduce SENS setting; Contact support if problem persists. |
| Light turns on too frequently/infrequently. | SENS or LUX settings are not optimal. | Adjust SENS and LUX settings according to desired operation. |
| Light turns off too quickly/slowly. | TIME setting is not optimal. | Adjust TIME setting to desired duration. |
