1. పరిచయం మరియు ఓవర్view
The ECOELER YM2511 Ceiling Occupancy Motion Sensor Switch is designed to automatically control lighting based on occupancy detection. Utilizing Passive Infrared (PIR) technology, it senses moving objects within its detection zone to turn lights ON and OFF, promoting energy efficiency.
This sensor features adjustable settings for time delay, sensitivity, and ambient light levels, allowing customization for various environments. It offers a 360-degree detection range, making it suitable for a wide array of applications including hallways, bathrooms, storage areas, and commercial spaces.

5.1 ప్రీ-ఇన్స్టాలేషన్ చెక్లిస్ట్
- సర్క్యూట్ బ్రేకర్ వద్ద పవర్ ఆఫ్ చేయండి.
- Ensure you have the necessary tools (screwdriver, wire strippers, electrical tape).
- Confirm the mounting location is suitable for a ceiling-mounted sensor, free from obstructions that might block the detection field.
5.2 వైరింగ్ సూచనలు
The ECOELER YM2511 requires a neutral wire for operation. Follow the wiring diagram provided with your product or consult a qualified electrician. Typical wiring involves connecting the sensor's wires to the building's electrical system (Line, Load, Neutral, Ground).
- బ్లాక్ వైర్: లైన్ (హాట్)
- వైట్ వైర్: తటస్థ
- రెడ్ వైర్: Load (to light fixture)
- Green/Bare Copper Wire: Ground (if applicable)
Secure all connections with wire nuts and electrical tape. Ensure no bare wires are exposed.
5.3 మౌంటు
Mount the sensor to a standard ceiling junction box or directly to a high bay fixture. The sensor is designed for optimal 360-degree detection when installed at a height of approximately 20 feet, providing a detection range of up to 24 feet in diameter.

6. ఆపరేషన్ మరియు సెట్టింగ్లు
After installation and restoring power, the sensor will enter a warm-up period. The integrated LED indicator will flash during motion detection. The sensor features three adjustable dials for customization:

Figure 5: Adjustment dials for Time, Sense, and Light. This image shows the three rotary dials on the sensor's face, labeled for adjusting time delay, sensitivity, and ambient light detection.
- TIME (1): Controls how long the light or fan remains ON after no motion is detected. Adjustable from 15 seconds to 30 minutes.
- Rotate clockwise for longer delay.
- Rotate counter-clockwise for shorter delay.
- SENSE (2): Adjusts the sensitivity of the motion detection. This helps prevent unwanted activations from minor movements or distant traffic. Adjustable from 20% to 100%.
- Rotate clockwise for higher sensitivity (detects smaller movements, wider range).
- Rotate counter-clockwise for lower sensitivity (detects larger movements, shorter range).
- కాంతి (3): Prevents the sensor from automatically turning ON lights or fans if there is sufficient ambient lighting in the area (Daylight Harvesting).
- Rotate clockwise to allow activation in brighter conditions.
- Rotate counter-clockwise to only activate in darker conditions.
The sensor is compatible with various lighting types:
