5. Installation
5.1 Pre-Installation Checklist
- Ensure the power supply is disconnected at the circuit breaker.
- Confirm the mounting location is stable and free from excessive vibrations.
- Avoid mounting near heat sources (e.g., air conditioners, heaters) or direct sunlight, as these can interfere with sensor performance.
- Ensure the detection area is clear of obstructions.
5.2 Mounting Instructions
- Separate the front cover from the base of the sensor by gently twisting or prying.
- Position the sensor base at the desired ceiling location. Mark the drilling points using the holes on the base.
- Drill holes at the marked positions. Insert the provided wall anchors if mounting into drywall or similar materials.
- Secure the sensor base to the ceiling using the provided screws.
5.3 Wiring Diagram
Refer to the diagram below and the markings on the sensor's terminal block for correct wiring. Ensure all connections are secure.
Figure 5.1: Close-up of the wiring terminals. From left to right: Neutral (N), Live (L), Switched Live (L'), and Neutral for Load (N).
- 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 Switched Live (L') wire from the sensor to the live input of your light fixture or other load.
- Connect the Neutral (N) wire from your light fixture or other load to the 'N' terminal on the sensor (or directly to the main neutral if applicable).
After wiring, carefully reattach the front cover to the sensor base. Restore power only after ensuring all connections are correct and secure.
6. Operation and Settings
The MCE85 sensor features two adjustable dials to customize its operation:
Figure 6.1: The 'TIME' and 'LUX' adjustment dials.
6.1 TIME Adjustment
The 'TIME' dial controls how long the connected light or device remains ON after motion is last detected. Rotate the dial to set the desired duration:
- Minimum: Approximately 10 seconds
- Maximum: Approximately 15 minutes
6.2 LUX Adjustment
The 'LUX' dial determines the ambient light level at which the sensor will activate. This allows the sensor to operate only when natural light is insufficient.
- Sun Symbol (High LUX): The sensor will activate regardless of ambient light (day and night operation).
- Moon Symbol (Low LUX): The sensor will only activate when the ambient light is low (night-time operation).
- Range: Adjustable from approximately 3 lux (dark) to 2000 lux (daylight).

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. | No power; incorrect wiring; LUX setting too low (sensor thinks it's daytime); faulty bulb/device. | Check power supply; verify wiring connections; adjust LUX setting towards 'Sun' symbol; test connected light/device. |
| Light stays on continuously. | Constant motion in detection area; incorrect wiring (e.g., L' connected directly to L); TIME setting too long; sensor malfunction. | Remove sources of constant motion; re-check wiring; reduce TIME setting; if problem persists, contact support. |
| Light turns on too frequently or not frequently enough. | LUX or TIME settings are not optimal; sensor is detecting unwanted movement (e.g., pets, drafts); sensor is obstructed. | Adjust LUX and TIME settings; reposition sensor to avoid unwanted detection; ensure clear line of sight for the sensor. |
| Detection range is too short or too long. | Mounting height is incorrect; environmental factors (temperature, air currents). | Ensure mounting height is within recommended range (typically 2.2-4m); minimize environmental interference. |
9. Maintenance
The Maclean Energy MCE85 motion sensor requires minimal maintenance.
- Cleaning: Gently wipe the sensor lens and housing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check for any loose wiring or physical damage.
- Power Disconnection: Always disconnect power before cleaning or inspecting the device.
