Major Tech MS363
360° Ceiling Mount Microwave Sensor
Instruction Manual - Indoor Installation
1. Introduction
The MS363 automatically activates lights or electrical devices within its rated load capacity. It offers detection through obstacles like doors, glass panels, and thin walls, featuring a 360° range when ceiling-mounted. Adjustable settings for time, Lux level, and sensitivity allow for tailored performance. The MS363 is easily integrated into new or existing installations and excels at detecting subtle movements over large areas, outperforming PIR sensors. Its IP20 rating makes it suitable for indoor use. Installation requires a qualified electrician.

3. Function
a. Day/Night Identification (Lux Mode)
The sensor's operating state can be adjusted based on ambient light. It can function both day and night when set to the 'Sun' (maximum) position. In the '3' (minimum) position, it operates only in ambient light below 3 LUX. Refer to the testing pattern for adjustment details.
b. Adjustable Sensitivity (SENS Mode)
Sensitivity can be adjusted based on the installation location. The detection distance for wall mounting is between 2 to 16 meters.
c. Continuous Time Delay
When movement is detected while the light is already on, the countdown timer resets. The light remains illuminated for the full set duration from the most recent detection.
d. Adjustable Time Delay
The time delay can be set by the user to 10s, 30s, 90s, 3min, 6min, or 12min.
4. Control Setting Information
To set up the sensor:
- Turn the TIME knob counter-clockwise to the minimum (10s). Turn the LUX knob clockwise to the maximum (Sun).
- Upon switching on the power, the sensor requires approximately 30 seconds to warm up. Once movement is detected, the lamp will turn on. If no further movement is detected within the set duration, the light will turn off within 10 seconds (±3 sec).
- Turn the LUX knob counter-clockwise to the minimum (3). If ambient light exceeds 3 Lux, the sensor will not function. It will operate only in ambient light below 3 Lux (dark conditions).
Note: When testing in daylight, ensure the Lux knob is set to the 'Sun' position; otherwise, the sensor will not operate.
Control Panel Description: The control panel features three rotary knobs: LUX (for ambient light sensitivity), SENS (for detection sensitivity/distance), and TIME (for duration). The LUX knob has settings from '3' to 'Sun'. The SENS knob has settings from '2m' to '16m'. The TIME knob has settings from '10s' to '12min'.
Important Safety Note: The high-frequency output of the HF sensor is less than 0.2mW, which is approximately 1/5000th of a mobile phone's transmission power or a microwave oven's output. Keep the device away from children.
5. Installation & Wiring Options
Installation Steps:
- Unscrew and remove the fixing bracket from the sensor base.
- Insert the power cable into the provided slot.
- Connect the power cable to the terminal block according to the wiring diagram.
- Identify the ideal field of view and use the fixing bracket's mounting holes for correct alignment of the motion sensor.
- Drill holes and screw the fixing bracket into the marked location.
- Reconnect the sensor to the fixing bracket and fasten the screws.
- Once installation is complete, swivel the sensor head to point in the intended direction, secure it, and turn on the power to test.
WARNING: Danger of Death Through Electrical Shock
- Installation must be performed by a professional electrician.
- Always disconnect the power source before installation.
- Cover or shield any adjacent live components.
- Ensure the device cannot be accidentally switched on during installation.
- Verify that the power supply is disconnected.
Wiring Diagrams:
Single Sensor Installation: The diagram shows a single sensor connected to a power source (Live, Neutral) and a load (lamp). The sensor has terminals labeled L (Live input), N (Neutral input), L' (Live output to load), and N' (Neutral output to load).
Multiple Sensor Installation: The diagram illustrates three sensors wired in parallel. Each sensor receives Live and Neutral power. The Live output from each sensor is connected to the Live terminal of the load, and the Neutral output from each sensor is connected to the Neutral terminal of the load. This configuration allows multiple sensors to control a single load.
6. Microwave Sensor Information
The sensor provides a detection range from 1m to 3.5m vertically. Horizontally, it offers an adjustable detection range from 2m up to a maximum of 16m, with a 360° detection pattern.
7. Troubleshooting
| PROBLEM | POSSIBLE CAUSE | PROPOSED SOLUTION |
|---|---|---|
| Light or load does not turn on when movement is detected | 1. No mains voltage | Ensure connections to the power source and load are correct. Check the circuit breakers and switches. Ensure supply voltage is between 220V and 240V AC. |
| 2. Surrounding light may be too bright | Check if the Lux setting corresponds with the ambient light conditions. Relocate the sensor. | |
| 3. Control settings incorrect | Check if the Time delay is set to your required settings. Check the Lux settings. | |
| 4. Sensor positioning is incorrect | Check for any hindrance in front of the detector which may affect the reception of signals. Check if the ambient temperature is below 40°C. Confirm the installation height is between 2.2m and 4m. | |
| 5. Lights turn off while working or sitting at a desk | Check Time delay setting. Check the Lux levels. | |
| Light turns ON for no apparent reason (Intermittent fault) | 1. Animals, birds or pets | This possibly could be unavoidable. Relocate the sensor. |
| 2. Heat sources such as air conditioners, vents or heat extractor ducts activating the sensor | Control settings may have been set at daytime which can affect the night distances and sensitivity. Reset at night. | |
| 3. Light operates during the day | Reduce the Lux setting to the desired light setting. | |
| 4. Sensor affected when switching On/Off lights, fans or electrical devices on the same circuit | Check for an arcing or faulty switches. Connect the Microwave sensor to a separate circuit. | |
| Light remains ON continuously | 1. Control settings incorrect | Check Time delay setting. Check the Lux levels. |
| 2. False Triggering | Relocation of Microwave sensor may assist. Check the controls for Time and Lux levels. | |
| 3. Interference by sunlight | Control settings may have been set at daytime which can affect the night distances and sensitivity. Reset at night. |
