5. Setup and Installation
Follow these steps for proper installation of your motion sensor.
5.1 Mounting the Sensor
- Choose a suitable mounting location. The sensor can be wall-mounted or ceiling-mounted. For optimal performance, install the sensor at a height of 1-2.5 meters.
- Mark the drilling points using the sensor's base as a template.
- Drill holes and insert the wall plugs.
- Secure the sensor base to the wall or ceiling using the provided screws.

5.2 Wiring Connections
Refer to the wiring diagram below. Ensure power is disconnected before making any connections.
- Connect the Live (L) wire from your power supply to the 'IN~ L' terminal on the sensor.
- Connect the Neutral (N) wire from your power supply to the 'IN~ N' terminal on the sensor.
- Connect the Live (L) wire of your load (e.g., light fixture) to the 'OUT~ L' terminal on the sensor.
- Connect the Neutral (N) wire of your load to the 'OUT~ N' terminal on the sensor.

5.3 Adjusting Detection Direction
After installation, the sensor head can be rotated up to 180 degrees to adjust the detection direction, allowing you to optimize the coverage area.

6. Operating Instructions
Once installed and powered on, the Greluma ZL780LUM motion sensor will automatically begin its operation cycle. The sensor detects changes in infrared radiation caused by human movement within its detection zone. When motion is detected and the ambient light level meets the set LUX threshold, the connected light fixture will turn on. The light will remain on for the duration of the set time delay and will turn off once no further motion is detected within that period.
7. Knob Adjustments
The sensor features two adjustable knobs to customize its operation:
Image: Close-up of the sensor's adjustment knobs for 'TIME' and 'LUX'.
7.1 TIME Adjustment
- This knob controls the duration the light remains on after motion is detected and then stops.
- The adjustable range is approximately 8 seconds to 7 minutes.
- If continuous motion is detected, the timer will reset and extend the 'on' time.
7.2 LUX Adjustment (Light Sensor)
- This knob determines the ambient light level at which the sensor will activate.
- Adjustable range: 3 to 2000 Lux.
- Setting to the 'sun' position (maximum LUX value) allows the sensor to operate both day and night.
- Setting to the 'moon' position (minimum LUX value) allows the sensor to operate only when the ambient light is below approximately 3 Lux (i.e., in darkness or very low light conditions).
8. Maintenance
- Cleaning: Periodically wipe the sensor lens with a soft, dry cloth to remove dust or dirt that may obstruct detection. Do not use abrasive cleaners or solvents.
- Inspection: Regularly check the sensor for any signs of damage or loose connections.
- Power Cycle: If the sensor behaves erratically, try turning off the power at the circuit breaker for a few minutes, then restore power.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. | No power to the sensor or light fixture. LUX setting is too low (moon position) during daytime. Faulty wiring connection. Motion not within detection range. | Check power supply and circuit breaker. Adjust LUX knob towards 'sun' position. Verify all wiring connections are secure. Ensure motion occurs within the sensor's detection area. |
| Light stays on continuously. | Continuous motion in detection area. TIME setting is too long. Wiring error (e.g., load directly connected to power). Sensor malfunction. | Remove obstructions or reposition sensor. Adjust TIME knob to a shorter duration. Re-check wiring against the diagram. Contact support if problem persists after checking other causes. |
| Light turns on and off too frequently. | Sensor is too sensitive. Interference from heat sources (e.g., vents, moving trees). | Adjust TIME and LUX settings. Reposition sensor to avoid interference. |
| Detection range is poor. | Obstructions blocking the sensor. Incorrect installation height. Temperature difference between ambient and moving object is too small. | Clear any obstructions from the sensor's view. Ensure installation height is within 1-2.5m. Sensor performance may vary with environmental conditions. |
