Applications of FCB18 Twilight Relay

Outdoor Lighting Control

The FCB18 twilight relay excels in controlling outdoor lighting systems for residential areas, commercial buildings, and public spaces. It automatically activates street lights, pathway illumination, garden lighting, and facade lighting when natural light diminishes, enhancing safety and security while conserving energy by ensuring lights operate only when necessary.

Security Lighting Systems

Security is paramount for both residential and commercial properties. The FCB18 twilight relay provides reliable control for security lighting systems, ensuring perimeter lights, entrance illumination, and surveillance support lighting activate precisely when ambient light falls below safe levels, deterring potential intruders and enhancing surveillance camera effectiveness.

Energy Management Solutions

In today’s energy-conscious world, the FCB18 twilight relay serves as an essential component in comprehensive energy management systems. By automating lighting based on actual ambient light conditions rather than fixed schedules, it eliminates wasteful operation during daylight hours or overcast conditions when artificial lighting isn’t yet required, leading to significant energy savings and reduced operational costs.

Průmyslové aplikace

Industrial facilities with outdoor work areas, loading docks, and parking facilities benefit from the FCB18’s robust design and reliable performance. Its strong anti-interference capabilities make it particularly suitable for industrial environments where electrical noise and power fluctuations are common, ensuring consistent lighting control without false triggers or operational failures.

Průvodce instalací a zapojením

Pokyny pro montáž

The FCB18 twilight relay is designed for quick and secure installation on standard 35mm DIN rails according to EN/IEC 60715 specifications. Its compact dimensions (90mm*18mm*64mm) allow for efficient use of space in distribution panels and control cabinets. For optimal performance, install the unit in a location with adequate ventilation and protection from extreme environmental conditions.

Schéma zapojení

The FCB18 features clearly labeled terminals for straightforward wiring:

• A1-A2: Power supply connection terminals
• 14-11-12: Output relay contacts (SPDT configuration)
• S1-S2: Light sensor connection terminals

When connecting the FCB18, ensure all power is disconnected before beginning installation. Use appropriately sized conductors (AWG13-20) and maintain the specified stripping length of 7mm (0.28in) for secure connections. The included FCB-PB 20cm sensor should be positioned to accurately monitor ambient light levels without interference from artificial light sources that could cause feedback loops.

Mode Selection and Sensitivity Adjustment

The FCB18 twilight relay features intuitive controls for operation mode selection and light sensitivity adjustment:

1. Use the mode selector switch to choose between AUTO, ON, and OFF operation modes based on your specific requirements.
2. Adjust the light sensitivity threshold using the precision dial, allowing calibration from low light levels to higher ambient light conditions depending on your application needs.
3. Observe the LED indicators for confirmation of proper operation: green LED indicates power supply status, while the red LED shows relay activation state.

Řešení problémů a údržba

Běžné problémy a jejich řešení

While the FCB18 twilight relay is designed for reliable, trouble-free operation, users might occasionally encounter operational issues. Here are solutions for common scenarios:

Lights Fail to Activate in Darkness

• Check power supply connections and verify voltage is within the acceptable range (-15%~+10% of rated voltage).
• Ensure the light sensor is properly connected to terminals S1-S2 and positioned correctly to monitor ambient light.
• Verify the sensitivity setting is appropriate for the installation environment.
• Confirm the mode selector is set to AUTO rather than OFF position.

Lights Remain On During Daylight

• Check that the light sensor is not obstructed or positioned where it’s affected by shadows or artificial light.
