2. Safety Information

WARNING: Installation and maintenance must be performed by qualified personnel only. Disconnect power before installation or servicing to prevent electric shock.

• Ensure the power supply matches the device specifications (230 V AC).
• Do not expose the device to extreme temperatures or corrosive environments beyond its specified operating range.
• Verify all connections are secure and correctly wired according to local electrical codes.
• The device is designed for permanent installation.

3. Product Overview

The Orbis Citylux Twilight Switch (OB131412) is an electronic device that manages lighting systems by detecting ambient luminosity. It features a robust design for outdoor use and includes a mechanism to prevent false switching due to transient light changes.

Key Features:

• Automatic lighting control based on ambient light.
• Adjustable twilight threshold (3-200 Lux).
• Integrated delay (approx. 60 seconds) to prevent false switching.
• IP65 protection against atmospheric phenomena.
• Easy installation with a sliding mounting bracket.

4. Setup and Installation

The Orbis Citylux Twilight Switch is designed for wall or pole mounting using its integrated bracket. Follow these steps for proper installation:

1. Choose a Location: Select a mounting location that receives consistent ambient light, free from direct artificial light sources, reflections, or shadows that could interfere with light detection.
2. Mount the Bracket: Secure the mounting bracket to the desired surface (wall or pole) using appropriate screws or fasteners. Ensure the bracket is firmly attached.
3. Wiring:
   • Disconnect Power: Before making any electrical connections, ensure the main power supply is turned off at the circuit breaker.
   • Connect Input Power: Connect the 230 V AC power supply to the designated input terminals of the switch.
   • Connect Load: Connect the lighting circuit (load) to the output terminals of the switch. The switch features a normally open contact.
   • Secure Connections: Ensure all wire connections are tight and properly insulated.
4. Attach the Switch: Slide the twilight switch unit onto the fixed mounting bracket until it clicks securely into place.
5. Restore Power: Once installation is complete and all connections are verified, restore power to the circuit.

5. Operating Instructions

The Orbis Citylux Twilight Switch operates automatically based on the detected ambient light level. The primary adjustment is the twilight threshold.

1. Initial Power-Up: Upon initial power-up, the device will perform a self-test. The lighting will typically remain off if there is sufficient ambient light, or turn on if it is dark, subject to the set threshold and delay.
2. Adjusting the Twilight Threshold (Sensitivity):
   • Locate the selector switch on the side of the device. This selector allows adjustment of the luminosity threshold (3-200 Lux) at which the lighting system will activate or deactivate.
   • Rotate the selector to increase or decrease the sensitivity. A lower Lux setting means the lights will turn on when it is darker, and turn off when it is brighter. A higher Lux setting means the lights will turn on when it is still relatively bright, and turn off when it is very bright.
   • Adjust the setting gradually and observe the system's behavior over a day/night cycle to find the optimal setting for your environment.
3. Operation Logic:
   • When ambient light falls below the set threshold, the output contact will close, turning the lights ON after approximately 60 seconds.
   • When ambient light rises above the set threshold, the output contact will open, turning the lights OFF after approximately 60 seconds.
   • The 60-second delay prevents rapid switching due to temporary light changes (e.g., car headlights, passing clouds).

6. Maintenance

The Orbis Citylux Twilight Switch is designed for minimal maintenance. However, periodic checks can ensure optimal performance.

• Cleaning: Periodically clean the light sensor window with a soft, damp cloth to remove dust, dirt, or debris that might obstruct light detection. Do not use abrasive cleaners.
• Inspection: Annually inspect the device for any signs of physical damage, loose connections, or wear. Ensure the mounting is still secure.
• Environmental Factors: Ensure the sensor area remains clear of new obstructions (e.g., growing foliage, new structures) that could affect its light detection.
• Power Disconnection: Always disconnect power before performing any cleaning or inspection that requires direct contact with the device.
