Overview

3. Usage Features
4. Maintenance Features

The LX-PR-29A Infrared Sensor is an energy-saving switch designed for automatic control of lighting based on motion detection. It integrates a highly sensitive detector, an integrated circuit, and Surface Mount Technology (SMT) to provide convenient, safe, and practical functions. The device utilizes infrared energy emitted by humans as a control signal source, activating connected loads when a person enters its detection field. It can automatically distinguish between day and night conditions, making it versatile for various environments. The sensor is easy to install and features indicators for power and detection status.

Function Description

The primary function of the LX-PR-29A is to automatically switch on a connected load (e.g., a lamp) when motion is detected within its sensing range and angle. It then switches off the load after a set time delay if no further motion is detected. This automation helps in saving energy by ensuring lights are only on when needed. The sensor's wide detection field is achieved by a single internal detector.

Usage Features

The LX-PR-29A offers several user-adjustable features through its three control knobs:

1. SENS (Sensitivity/Detection Range): This knob adjusts the detection range. Turning it clockwise increases the range to a maximum of 8 meters, while turning it anti-clockwise decreases it to a minimum of 1 meter.
2. TIME (Time Setting): This knob controls how long the connected load remains on after motion is detected. Clockwise rotation increases the time up to 8±3 minutes. Turning it anti-clockwise decreases the time. At its minimum setting, it operates in "impulse mode." To set a short time mode from impulse mode, turn the knob slightly anti-clockwise until the LED blinks three times.
3. LUX (Light-Control): This knob determines the ambient light level at which the sensor will operate. Turning it clockwise allows the sensor to work in any light condition (up to 2000 LUX). Turning it anti-clockwise sets it to only operate in low light conditions (approximately 10 LUX), meaning it will only activate when it's dark.

Sensor's LED Indicators:

• The LED lights up continuously after power-on and turns off once the unit enters its stable working state.
• The LED blinks once each time the unit receives a sensing signal, confirming detection.

Installation and Setup: The sensor is designed for ceiling installation at a height of 2.5 to 3.5 meters.

1. Before installation, ensure the power is switched off.
2. Rotate the top cover anti-clockwise to remove it, then loosen the screws fixing the bottom cover.
3. Mount the bottom cover to the desired position using screws.
4. Connect the power wire (brown L for live, blue N for neutral) and the load wire (L' red for load) to the connection line column within the sensor, following the provided wiring diagram.
5. Attach the top cover by aligning it and rotating it clockwise until secure.
6. After installation, switch on the power. The unit will enter a stable working state after about 1 minute.
7. For testing, set the TIME knob to minimum and the LUX knob to the "sun" position. If it functions correctly, adjust the TIME, LUX, and SENS settings to your specific needs.

Maintenance Features

The manual provides troubleshooting steps for common issues:

Load not working:

• Verify correct power and load connections.
• Check if the load (e.g., lamp) is functional.
• Observe if the indicator lamp accelerates its speed after detection.
• Ensure the working light conditions match the light-control setting.

Poor sensitivity:

• Check for any obstructions in front of the detection window.
• Verify that the ambient temperature is not excessively high.
• Confirm that the signal source (person) is within the detection field.
• Ensure the installation height matches the recommended height.
• Check if the moving orientation is correct relative to the sensor.

Sensor not shutting off automatically:

• Check for continuous signals or movement within the detection field.
• Ensure the time setting is not set to the longest duration.
• Verify that the power supply matches the instruction's requirements.
• Check for significant temperature changes near the sensor (e.g., from air conditioning or central heating), which might interfere with detection.

Important Notes:

• Installation should be performed by a qualified electrician or experienced personnel.
• Avoid installing the sensor on unstable objects.
• Ensure there are no obstructions or moving objects directly in front of the detection window that could affect detection.
• Avoid installation near areas with significant air temperature alterations, such as air conditioners or central heating units.
• For safety, do not open the cover if you encounter issues after installation.
• In case of discrepancies between the product and the instruction manual, the product's actual behavior should take precedence.
