Setup and Installation
Proper installation is crucial for optimal performance and safety. Ensure power is disconnected before beginning installation.
1. Mounting Location
- The sensor can be mounted on a wall or ceiling.
- The recommended mounting height is approximately 1.8 to 2.5 meters (5.9 to 9.2 feet) for best detection range and coverage.
- Avoid mounting near heat sources, air conditioning vents, or direct sunlight, as these can interfere with sensor performance.
- Ensure the detection area is clear of obstructions.

2. Wiring Instructions
The sensor requires a 10mm mounting hole. Follow the wiring diagram carefully. It is recommended that wiring be performed by a qualified electrician.
- Brown Wire: Connect to Live (L) input AC 85-265V.
- Blue Wire: Connect to Neutral (N) input AC 85-265V. This wire also serves as the common neutral for the load.
- Red Wire (L1): Connect to the Live input of your lamp or ballast.
- Ensure all connections are secure and insulated.

Operating Instructions and Settings
The Greluma PIR Motion Sensor features three adjustable knobs for fine-tuning its operation:

1. SENS (Sensitivity)
- Controls the detection distance of the sensor.
- Turn the knob towards '+' for maximum detection distance (up to 12m).
- Turn the knob towards '-' to reduce the detection distance.
2. TIME (Time Delay)
- Adjusts how long the connected light or device remains on after motion is detected and then stops.
- The delay time can be set from approximately 5 seconds to 8 minutes.
- Turn the knob towards '+' for a longer delay, and towards '-' for a shorter delay.
3. LUX (Light Sensitivity)
- Determines the ambient light level at which the sensor will operate.
- Sun Icon (Daylight Mode): When set to the sun icon, the sensor will operate regardless of ambient light, meaning it will detect motion and activate the light during both day and night.
- Moon Icon (Night Mode): When set to the moon icon, the sensor will only activate the connected device when the ambient light falls below a certain threshold (i.e., during evening or in dark environments). This setting helps save energy by preventing lights from turning on during the day.
- The LUX sensitivity is adjustable from 2 to 2000 Lux.
Maintenance
The Greluma PIR Motion Sensor is designed for low maintenance. To ensure continued optimal performance:
- 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.
- Environmental Conditions: Ensure the operating humidity remains below 93% RH to prevent damage to internal components.
- Connection Check: Occasionally inspect wiring connections for any signs of wear or loosening. Ensure power is off before checking connections.
Troubleshooting
If you experience issues with your Greluma PIR Motion Sensor, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. |
|
|
| Light stays on continuously or turns on too frequently. |
|
|
| Sensor feels warm to the touch. | Normal operation for some electronic components, especially under load. | While some warmth is normal, excessive heat could indicate an issue. Ensure proper ventilation and that the load (e.g., light wattage) does not exceed the sensor's specifications. If it's excessively hot or emitting smoke/smell, disconnect power immediately. |
