Operating Instructions
The light fixture features adjustable settings for operating mode and hold time. These settings are controlled by small switches located near the motion sensor on the fixture's surface.
- Selecting Operating Mode:
- Locate the mode switch (labeled AUTO, ON, G).
- Slide the switch to your desired mode:
- AUTO: Motion and light sensor activated. Light turns on only when motion is detected in dark conditions.
- ON: Light remains continuously on, regardless of motion or ambient light.
- G: Motion sensor activated. Light turns on when motion is detected, both during the day and at night.
- Adjusting Hold Time:
- Locate the hold time switch (labeled 30S, 120S, 180S).
- Slide the switch to set how long the light remains on after motion is no longer detected:
- 30S: 30 seconds
- 120S: 120 seconds (2 minutes)
- 180S: 180 seconds (3 minutes)

Troubleshooting
If you encounter issues with your light fixture, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power supply; incorrect wiring; ambient light too bright (in AUTO mode). | Check circuit breaker. Verify wiring connections. Switch to G mode to test motion sensor in brighter conditions. |
| Light turns on unexpectedly or stays on too long. | Motion sensor interference; incorrect mode/hold time setting; faulty sensor. | Ensure no objects are moving within the sensor's range. Adjust hold time setting. Try switching modes. |
| Light flickers. | Unstable power supply; loose wiring connection. | Check power supply stability. Verify all wire connections are secure. |
