6. Setup
Before proceeding with installation, ensure you have the necessary tools and have reviewed the safety information.
- Choose Location: Select a mounting location where the sensor will receive natural ambient light without being obstructed by shadows or directly illuminated by the controlled light source. Avoid locations near reflective surfaces or other light sources that could interfere with its operation.
- Prepare Wiring: Identify the power supply wires (Line, Neutral) and the load wires (to the light fixture).
- Power Off: Crucially, turn off the main power supply to the circuit at the breaker before any wiring work.
7. Installation
Follow these steps for proper installation of the photocell sensor switch.
Image 7.1: Illustration of correct and incorrect mounting methods. Ensure the sensor is not obstructed or facing the controlled light source.
- Mounting: Use the provided mounting bracket and screws to securely attach the sensor switch to a wall or pole. Ensure the 'UP' arrow on the bracket points upwards. The sensor should be positioned to detect ambient light effectively, away from direct light of the fixture it controls.
- Wiring: Refer to the wiring diagram below. Connect the input power (Line and Neutral) and the output load wires to the corresponding terminals inside the sensor switch. Ensure all connections are tight and secure.

- Secure Cover: Once wiring is complete, carefully reattach the sensor cover, ensuring it is properly sealed to maintain weather resistance.
- Test: Restore power to the circuit. The light should turn on if it is dark, or off if it is bright. You can test by covering the sensor to simulate darkness.

8. Operating Instructions
The Greluma Photocell Sensor Switch operates automatically based on ambient light levels.
Image 8.1: The sensor automatically detects ambient light to control connected lighting.
- Automatic On/Off: The sensor will automatically turn on the connected lights when the ambient light level falls below the set sensitivity threshold (dusk) and turn them off when the light level rises above the threshold (dawn).
- Sensitivity Adjustment: The twilight sensitivity can be adjusted between 5 and 50 Lux. This adjustment is typically done via a small dial or screw located on the sensor unit (refer to product components for exact location if available). Adjusting this allows you to fine-tune when the lights turn on or off based on your specific environmental conditions and preferences.
9. Maintenance
Regular maintenance ensures optimal performance and longevity of your photocell sensor switch.
- Cleaning: Periodically clean the sensor lens with a soft, damp cloth to remove dust, dirt, or debris that may accumulate and interfere with light detection. Do not use abrasive cleaners.
- Inspection: Annually inspect the wiring connections for any signs of corrosion or loosening. Check the housing for cracks or damage.
- Obstruction Check: Ensure no new obstructions (e.g., growing foliage, new structures) are blocking the sensor's view of ambient light.
- Power Off: Always disconnect power before performing any cleaning or inspection.
10. Troubleshooting
If you encounter issues with your photocell sensor switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights stay on during the day. | Sensor is obstructed or not receiving enough light. Sensitivity setting is too low. | Clear any obstructions from the sensor. Adjust the sensitivity setting to a higher Lux value. |
| Lights do not turn on at night. | Sensor is receiving too much light (e.g., from a nearby street light). Wiring issue. Sensitivity setting is too high. | Relocate the sensor or shield it from interfering light sources. Check all wiring connections. Adjust the sensitivity setting to a lower Lux value. |
| Lights flicker. | Intermittent power supply. Sensor is near a fluctuating light source. Faulty wiring. | Check power supply stability. Relocate the sensor. Inspect and secure wiring connections. |
| No power to the light. | Blown fuse or tripped circuit breaker. Incorrect wiring. Faulty light fixture. | Check and reset circuit breaker/replace fuse. Verify wiring against the diagram. Test the light fixture independently. |
If the problem persists after attempting these solutions, contact a qualified electrician or Greluma customer support.
