3.製品オーバーview

The Greluma ZL778LUM is a passive infrared (PIR) motion sensor designed for ceiling mounting. It offers a wide detection area and customizable settings to suit various applications.

図3.1: 前面 view of the Greluma ZL778LUM motion sensor.

主な特徴:

• 広い検出範囲: Optimal motion detection with a 360° field of view and a maximum range of 6 meters.
• 調整可能な光センサー（LUX）： Configurable light sensitivity from 10 Lux (moon symbol) to 2000 Lux (sun symbol). This allows the sensor to operate only in darkness, or both day and night.
• 調整可能な時間遅延（TIME）: Set the duration the connected light remains on after motion detection, from 10 seconds to 7 minutes. The timer resets with continuous motion.
• Adjustable Sensitivity (SENS): Control the detection distance by rotating the knob clockwise to increase sensitivity or counter-clockwise to decrease it.
• 多用途なアプリケーション: Suitable for various indoor locations such as garages, corridors, basements, stairwells, kitchens, wardrobes, and attics.

4. 仕様

5. セットアップとインストール

Before proceeding with installation, ensure the power supply is disconnected at the main circuit breaker.

5.1センサーの取り付け

The sensor is designed for ceiling mount installation. Choose a location that provides an unobstructed view of the area to be monitored and is within the recommended installation height of 2 to 4.5 meters.

1. Separate the mounting base from the sensor unit.
2. Position the mounting base on the ceiling at the desired location. Mark the drilling points.
3. Drill holes and insert wall plugs (if necessary for your ceiling material).
4. Secure the mounting base to the ceiling using screws.

5.2配線手順

Refer to the wiring diagram below for correct electrical connections. Incorrect wiring can damage the sensor or connected devices.

図5.1：背面 view of the sensor with terminal block for electrical connections.

Figure 5.2: Detailed wiring diagram showing input (AC110-240V, N, L) and output (LOAD, A) connections.

• Connect the Neutral (N) wire from your power supply to the 'N' terminal on the sensor.
• Connect the Live (L) wire from your power supply to the 'L' terminal on the sensor.
• Connect the Neutral wire of your load (e.g., light fixture) to the 'N' terminal on the sensor (often shared with input neutral).
• Connect the Live wire of your load to the 'A' (Output) terminal on the sensor.
• After wiring, carefully attach the sensor unit to the mounted base, ensuring it is securely fastened.

Important: Ensure all connections are secure and insulated. Restore power only after the installation is complete and verified.

6. 操作手順と調整

The Greluma ZL778LUM sensor features three adjustable knobs for customizing its operation: TIME, SENS, and LUX.

Figure 6.1: Location of the TIME, SENS, and LUX adjustment knobs on the sensor.

6.1 TIME (Time Delay) Adjustment

This knob controls how long the connected light remains on after motion is detected and then stops. The range is approximately 10 seconds to 7 minutes.

• Rotate clockwise (+) to increase the time delay.
• Rotate counter-clockwise (-) to decrease the time delay.
• If motion is detected again before the set time expires, the timer will restart.

6.2 SENS (Sensitivity) Adjustment

This knob adjusts the detection distance of the sensor.

• Rotate clockwise (+) to increase the detection distance (maximum 6 meters).
• Rotate counter-clockwise (-) to decrease the detection distance.

6.3 LUX (Light Sensor) Adjustment

This knob determines the ambient light level at which the sensor will activate. This allows you to choose whether the sensor operates during the day, at night, or both.

• "Sun" Position (Max LUX, ~2000 Lux): センサーは周囲の光に関係なく、昼夜を問わず動作します。
• "Moon" Position (Min LUX, <3 Lux): The sensor will only activate when the ambient light level is below approximately 3 Lux, meaning it will only operate in dark conditions (e.g., at night).
• Adjust the knob to your desired light threshold.

7. メンテナンス

The Greluma ZL778LUM motion sensor requires minimal maintenance.

• Ensure the sensor lens is kept clean and free from dust or obstructions. Use a soft, dry cloth for cleaning.
• Do not use abrasive cleaners or solvents, as these can damage the sensor's surface.
• Periodically check electrical connections for any signs of wear or loosening. Disconnect power before inspection.
