5. Setup and Installation
Follow these steps for proper installation of your flood light:
- Prepare for Installation: Turn off power at the circuit breaker. Ensure you have a suitable 4.33-inch junction box (not included).
- Fix Mounting Plate: Securely attach the mounting plate to the junction box using the provided screws.
- Connect Wires: Connect the electrical wires. The black wire is for hot, the white wire for negative, and the green wire for ground. Use wire nuts to secure connections.
- Fix LED Light: Attach the LED light fixture onto the mounting plate.
- Choose Working Mode: Select your desired working mode using the switch on the motion sensor.
- Restore Power: Once installation is complete and secure, restore power at the circuit breaker.

6. Operating Instructions
Your SANSI flood light features a motion sensor with adjustable settings and multiple operating modes.
6.1. Sensor Adjustments (Lux, Time, Range)
The motion sensor has three adjustable dials:
- LUX: Adjusts the ambient light level at which the sensor will activate the light. From 0 (always on, regardless of ambient light) to ∞ (only activates in very dark conditions).
- TIME: Sets the duration the light stays on after motion is detected, ranging from 1 to 10 minutes.
- RANGE: Controls the sensitivity and detection distance of the motion sensor, up to a maximum of 72 feet.

6.2. Recommended Lux Setting
For optimal Dusk to Dawn functionality, it is recommended to set the LUX dial halfway. Ensure that the light heads do not directly illuminate the motion sensor, as this can cause flickering or improper operation.

6.3. Operating Modes
The flood light offers four distinct operating modes:
- Auto (Motion Sensor Mode): The light turns on for the set duration (1-10 minutes) at night when motion is detected.
- Dusk to Dawn Mode: The light automatically turns on at dusk and turns off at dawn, providing continuous illumination throughout the night.
- On-Time Mode: The light functions as a normal light, staying on continuously until manually switched off.
- Test Mode: The light turns on for only 5 seconds during daytime or night once it detects motion. This mode is useful for testing sensor functionality and coverage area after installation.

7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your flood light:
- Cleaning: Periodically clean the light fixture and motion sensor lens with a soft, damp cloth to remove dirt, dust, or debris. Do not use abrasive cleaners or solvents.
- Inspection: Annually inspect the wiring and connections for any signs of wear, damage, or corrosion. Ensure all mounting screws are tight.
- Obstruction Check: Ensure no new obstructions (e.g., growing foliage) are blocking the motion sensor's field of view.
8. Troubleshooting
If you encounter issues with your flood light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light flickers or turns on/off erratically. | Light heads are reflecting light onto the motion sensor; Lux setting is too sensitive. | Adjust the angle of the light heads to prevent direct illumination of the sensor. Adjust the LUX dial to a less sensitive setting. |
| Light stays on continuously. | Operating mode set to 'On-Time' or 'Dusk to Dawn'; continuous motion detected; sensor malfunction. | Verify the mode switch is set to 'Auto' if motion detection is desired. Check for constant motion in the detection zone. If problem persists, contact support. |
| Light does not turn on. | No power; incorrect wiring; sensor not detecting motion; Lux setting too high. | Check circuit breaker. Verify wiring connections. Ensure motion is within range and the LUX setting is appropriate for current ambient light. |
| Motion sensor range is poor. | Obstruction in sensor's field of view; RANGE dial set too low. | Clear any obstructions. Adjust the RANGE dial to increase sensitivity and detection distance. |
