5. Setup and Installation
5.1 Choosing a Location:
- Mount the sensor at a height of 1.8m to 2.2m for optimal detection.
- Avoid mounting near heat sources (e.g., air vents, direct sunlight) or objects that may cause rapid temperature changes, as this can lead to false triggers.
- Ensure the detection area is clear of obstructions.

5.2 Mounting the Device:
- Turn off the main power supply before starting installation.
- Open the sensor casing.
- Mark the desired mounting position on the wall.
- Drill holes and insert the provided wall anchors.
- Secure the sensor base to the wall using the provided screws.

5.3 Wiring Connections:
Connect the power supply and load wires according to the wiring diagram. Ensure all connections are secure and insulated.
- L: Live wire (Input)
- N: Neutral wire (Input)
- L': Live wire (Output to load)

Figure 7: Wiring diagram. Connect Live (L), Neutral (N), and Load (L') wires as shown.
After wiring, close the sensor casing and restore power.
6. Operating Instructions
The Maclean MCE385 motion detector features two adjustable knobs on its underside: TIME and LUX.

Figure 8: TIME and LUX adjustment knobs.
6.1 TIME Adjustment:
The TIME knob controls how long the connected light or device remains on after motion is detected and the detection area is clear. Rotate the knob to set the desired delay:
- Minimum setting: Approximately 10 seconds (fully counter-clockwise).
- Maximum setting: Approximately 15 minutes (fully clockwise).

Figure 9: TIME adjustment knob.
6.2 LUX Adjustment:
The LUX knob determines the ambient light level at which the sensor will activate the connected device. Rotate the knob to set the desired light sensitivity:
- Sun symbol (fully clockwise): The sensor will operate both day and night (high LUX sensitivity).
- Moon symbol (fully counter-clockwise): The sensor will only operate in low light conditions (e.g., dusk or night, low LUX sensitivity).

Figure 10: LUX adjustment knob.
6.3 Walk Test:
After installation and initial settings, perform a walk test to verify the detection area and functionality:
- Set the TIME knob to minimum (10s) and the LUX knob to maximum (sun symbol) for daytime testing.
- Walk through the desired detection area. The connected light should turn on.
- Step out of the detection area. The light should turn off after the set time delay.
- Adjust the sensor's angle or location if the detection area is not satisfactory.
- Once satisfied, set the TIME and LUX knobs to your preferred operational settings.
7. Maintenance
- Cleaning: Regularly clean the sensor lens with a soft, dry cloth to ensure optimal performance. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check the wiring connections and mounting for any signs of wear or damage.
- Power: Disconnect power before performing any cleaning or maintenance.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on when motion is detected. |
|
|
| Light stays on continuously. |
|
|
| False triggers (light turns on without apparent motion). |
