4. Product Overview and Features
The Greluma ZL926LUM is a high-sensitivity passive infrared (PIR) motion sensor designed to automatically control lighting based on detected movement and ambient light levels. It is suitable for both indoor and outdoor applications.
Key Features:
- Wide Detection Range: Up to 12 meters (at 24°C).
- Broad Detection Angle: 180 degrees for comprehensive coverage.
- Adjustable Light Sensor (LUX): Configurable to operate day and night (max LUX) or only in low light conditions (min LUX, below 3 Lux).
- Adjustable Time Delay (TIME): Set the duration the light stays on after motion detection, from 7 seconds to 7 minutes. The delay is continuously added if subsequent motion is detected.
- Energy Efficient: Utilizes passive infrared technology, consuming minimal power.
- Versatile Applications: Ideal for garages, hallways, basements, staircases, kitchens, wardrobes, lofts, and outdoor areas.

6. Installation and Setup
6.1 Mounting Location
- Choose a stable surface for mounting, such as a wall or ceiling.
- The optimal installation height is between 1 and 2.5 meters.
- Avoid mounting near heat sources (e.g., air conditioners, heaters) or in direct sunlight, as this may affect sensor performance.
- Ensure the detection area is clear of obstructions.

6.2 Wiring Instructions
Always disconnect power at the circuit breaker before performing any wiring.
- Open the sensor casing carefully.
- Connect the live (L) wire from your power supply to the 'L' terminal on the sensor.
- Connect the neutral (N) wire from your power supply to the 'N' terminal on the sensor.
- Connect the live wire of your light fixture (load) to the 'L' terminal of the output.
- Connect the neutral wire of your light fixture (load) to the 'N' terminal of the output.
- Ensure all connections are secure.
- Close the sensor casing and secure it with screws.

7. Operation
The sensor features two adjustable knobs: TIME and LUX. These allow you to customize the sensor's behavior according to your needs.
7.1 TIME Adjustment
- The TIME knob controls how long the connected light remains on after motion is detected.
- Adjustable range: Approximately 7 seconds to 7 minutes.
- Turning the knob towards '+' increases the delay time.
- Turning the knob towards '-' decreases the delay time.
- If motion is detected again before the set time expires, the timer will reset and the light will remain on for the full duration from the last detection.
7.2 LUX Adjustment
- The LUX knob determines the ambient light level at which the sensor will activate the connected light.
- 'Sun' Position (Max LUX): The sensor will operate both during the day and at night, regardless of ambient light.
- 'Moon' Position (Min LUX): The sensor will only activate the light when the ambient light level is less than approximately 3 Lux (i.e., in dark conditions).
- Adjust the LUX knob to your desired operating condition.

8. Maintenance
- Ensure the power is off before cleaning.
- Wipe the sensor lens and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Regularly check for any loose wiring connections.
- Keep the sensor lens clear of dust, dirt, or obstructions that could impair detection.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. |
|
