Passos d'instal·lació
- Muntatge: Securely mount the GRB8-01 onto a standard DIN rail.
- Connexió d'alimentació: Connect the AC 110V-240V power supply to the designated L and N terminals on the device.
- Light Sensor Connection: Connect the external light detection sensor to the appropriate terminals (IN) as indicated on the device. Ensure the sensor is placed where it can accurately measure ambient light without obstruction.
- Connexió de càrrega: Connect the lighting load (e.g., lamps) to the output terminals (3 and 4) of the relay.
- Connexions segures: Ensure all wire connections are tight and secure using a screwdriver. The device features tunnel terminals for reliable connections.

Instruccions de funcionament
The GRB8-01 offers three operating modes: ON, AUTO, and OFF, and allows for adjustable light sensitivity.
Selecció del mode
- Mode ON: In this mode, the connected lighting load will remain continuously ON, regardless of ambient light conditions. The green LED indicates power is supplied, and the red LED indicates the relay is active.
- Mode OFF: In this mode, the connected lighting load will remain continuously OFF. The green LED indicates power is supplied, and the red LED indicates the relay is inactive.
- Mode AUTOMÀTIC: This is the automatic control mode. The device will switch the lighting load ON or OFF based on the ambient light intensity detected by the sensor and the set sensitivity level.

Adjusting Light Sensitivity
In AUTO mode, you can adjust the light sensitivity (illumination range 1-100Lx) using the knob on the front panel. This determines the ambient light level at which the relay will switch the load. The device has a 2-minute action delay time to prevent rapid switching due to momentary light fluctuations.
- Assegureu-vos que el dispositiu estigui encès.
- Estableix el commutador de mode a AUTO.
- Turn the adjustment knob (marked with a sun/moon icon) to set the desired light sensitivity. Turning it towards the sun icon will require more light to turn off, and turning it towards the moon icon will require less light to turn off.
- Test the setting by simulating the desired light conditions. The load will switch ON/OFF after the 2-minute delay once the external light reaches your set adjustment value.
Manteniment
The GEYA GRB8-01 is designed for reliable operation with minimal maintenance. However, regular checks can ensure its longevity and optimal performance.
- Neteja: Periodically clean the exterior of the device and the light sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Comprovació de la connexió: Annually, or as needed, inspect all wiring connections to ensure they remain secure and free from corrosion.
- Col·locació del sensor: Ensure the light sensor remains unobstructed and clean to guarantee accurate light detection.
Resolució de problemes
If you encounter issues with your GEYA GRB8-01, refer to the following common troubleshooting steps:
- Device Not Powering On (No Green LED):
- Check the main power supply to the device.
- Verify that the L and N terminals are correctly wired and secure.
- Assegureu-vos el subministrament voltage is within the AC 110V-240V range.
- Load Not Switching (No Red LED Change):
- Confirm the device is set to AUTO mode.
- Check the light sensor connection and ensure it is not damaged or obstructed.
- Verify the light sensitivity setting. Adjust the knob to a different level and observe if the load switches after the 2-minute delay.
- Ensure the load itself (e.g., light bulb) is functional.
- Check the load wiring to terminals 3 and 4.
- Frequent Switching:
- This is usually prevented by the 2-minute delay. If it occurs, check for flickering light sources near the sensor or rapid changes in ambient light.
- Ensure the sensor is not exposed to direct, intermittent light (e.g., car headlights).
If problems persist after following these steps, please contact GEYA customer support for further assistance.
