2 സുരക്ഷാ വിവരങ്ങൾ

Please read all safety instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or other injuries.

• ഇലക്ട്രിക്കൽ സുരക്ഷ: Installation should only be performed by a qualified electrician in accordance with local electrical codes and regulations. Always disconnect power at the circuit breaker before installation or maintenance.
• ഇൻഡോർ ഉപയോഗത്തിന് മാത്രം: This device has an IP20 rating, meaning it is വാട്ടർപ്രൂഫ് അല്ല. Do not expose it to water, moisture, or high humidity. Install only in dry indoor locations.
• പ്രവർത്തന താപനില: Ensure the ambient temperature is within the specified range of -25°C to 60°C.
• ലോഡ് കപ്പാസിറ്റി: Do not exceed the maximum load of 400W for LED lighting. Overloading can damage the device and pose a fire hazard.
• ഇടപെടൽ: Microwave sensors can be affected by strong electromagnetic fields or other microwave devices. Avoid installing near such sources if possible.

3. ഇൻസ്റ്റലേഷൻ

The MC030S L sensor is designed for built-in installation, typically within a light fixture or ceiling cavity. Ensure adequate ventilation around the sensor.

3.1 വയറിംഗ് ഡയഗ്രം

Follow the wiring diagram below for correct electrical connection. The sensor uses spring terminals for secure connections.

Figure 3.1: Wiring connections for the Merrytek MC030S L. Connect Live (L) and Neutral (N) to the input, and the switched Live (L) and Neutral (N) to the LED load. An LED power supply (LED Netzteil) is shown as an exampലെ ലോഡ്.

• Connect the Live (L) and Neutral (N) wires from your power supply to the 'INPUT' terminals of the sensor.
• Connect the Live (L) and Neutral (N) wires of your LED fixture (or LED power supply) to the 'OUTPUT' terminals of the sensor.
• എല്ലാ കണക്ഷനുകളും സുരക്ഷിതവും ശരിയായി ഇൻസുലേറ്റ് ചെയ്തതുമാണെന്ന് ഉറപ്പാക്കുക.

3.2 വർദ്ധിച്ചുവരുന്ന പരിഗണനകൾ

The optimal mounting height for the sensor is up to 6 meters. The detection range is also up to 6 meters, and the detection angle is 150°.

Figure 3.2: Illustration of the sensor's detection angle, optimal mounting height, and effective detection range.

• Mount the sensor in a location where its detection area covers the desired space.
• Avoid placing the sensor directly next to large metal objects or thick walls that could obstruct the microwave signal.
• Consider the movement patterns in the area; the sensor detects radial movement more effectively than direct movement towards or away from it.

4. Setup and Configuration (DIP Switches)

The Merrytek MC030S L features nine DIP switches (1-9) for adjusting its settings. These switches allow you to customize the detection area, hold time, and daylight sensor threshold.

4.1 DIP Switch Settings Table

Refer to the table below for the various configuration options. 'ON' indicates the switch is in the ON position, '-' indicates the switch is in the OFF position.

Figure 4.2: Detailed table explaining the function of each DIP switch for Detection Area, Hold Time, and Daylight Threshold.

Detection Area (Switches 1, 2, 3)

Hold Time (Switches 4, 5, 6)

Daylight Threshold (Switches 7, 8, 9)

കുറിപ്പ്: After changing DIP switch settings, it is recommended to cycle the power to the sensor for the new settings to take full effect.

5. ഓപ്പറേഷൻ

The Merrytek MC030S L operates by detecting motion within its adjustable detection area and activating the connected lighting based on the configured hold time and daylight threshold.

Figure 5.1: Operational sequence of the motion sensor.

1. The motion detector is in standby mode and continuously monitors the environment for movement.
2. When motion is detected, and the ambient light level is below the set daylight threshold (if enabled), the light switches on within the defined hold time.
3. If new motion is detected during the active hold time, the light remains on and the hold time resets.
4. Multiple motion detectors can be used together to extend the detection area.
5. If no further motion is detected within the specified hold time, the light automatically switches off.

6. പരിപാലനം

The Merrytek MC030S L is designed for long-term, maintenance-free operation. However, a few guidelines can help ensure its longevity:

• വൃത്തിയാക്കൽ: Gently wipe the sensor's surface with a soft, dry cloth if it becomes dusty. Do not use abrasive cleaners or solvents.
• ഈർപ്പം: As stated in the safety information, this device is വാട്ടർപ്രൂഫ് അല്ല. Ensure it remains in a dry environment and protect it from any water splashes or condensation.
• പരിശോധന: Periodically check the wiring connections to ensure they remain secure.

7. പ്രശ്‌നപരിഹാരം

If you encounter issues with your Merrytek MC030S L motion sensor, consider the following common problems and solutions:

• Light does not turn on with motion:
  • Check power supply to the sensor and the connected light fixture.
  • Verify wiring connections are correct and secure.
  • Adjust the 'Detection Area' DIP switches (1-3) to a higher sensitivity (e.g., 100%).
  • Check the 'Daylight Threshold' DIP switches (7-9). If the ambient light is above the set threshold, the sensor will not activate the light. Try setting it to 'Disable' for testing.
  • Ensure there are no obstructions blocking the microwave signal.
• Light stays on continuously or turns on randomly:
  • Adjust the 'Detection Area' DIP switches (1-3) to a lower sensitivity (e.g., 10% or 25%).
  • Check for constant motion sources within the detection area (e.g., fans, swaying curtains, pets).
  • Consider potential interference from other electronic devices, especially strong Wi-Fi signals or other microwave devices nearby. Relocating the sensor or the interfering device might help.
  • Ensure the 'Hold Time' DIP switches (4-6) are set correctly.
• Light turns off too quickly or too slowly:
  • Adjust the 'Hold Time' DIP switches (4-6) to your desired duration.
• Daylight sensor not working as expected:
  • Adjust the 'Daylight Threshold' DIP switches (7-9) to a different lux level or 'Disable' to test.
  • Ensure the sensor's light sensor is not obstructed or exposed to direct, inconsistent light sources.
