This image displays the K-BUS KNX 24-Fold Multi-function Actuator. It features 24 output channels with corresponding LED indicators and manual control buttons. The device is designed for DIN-rail mounting and includes clearly labeled terminals for power, KNX bus, and load connections.

5. Installation

5.1 Mounting

1. The actuator is designed for DIN-rail mounting. Securely attach it to a standard 35mm DIN rail within an electrical enclosure.
2. Ensure adequate ventilation around the device to prevent overheating.

5.2 Wiring

All wiring must comply with local electrical codes. Use appropriate wire gauges for the rated current.

1. Power Supply: Connect the main power supply (230/400V AC, 50-60Hz) to the designated power terminals.
2. KNX Bus Connection: Connect the KNX bus cable to the KNX bus terminal. Ensure correct polarity.
3. Load Connections: Connect the loads (e.g., lights, motors for shutters, fan coil units) to the respective output channels (1-24). Each channel supports up to 10A. Ensure that the total current does not exceed the device's maximum rating.
4. Verify all connections are secure and properly insulated.

This diagram illustrates a comprehensive smart home system utilizing KNX technology. It shows various components such as power supplies, actuators, LED dimmers, IP gateways, and sensors (e.g., air quality, brightness, motion, smoke, gas) all interconnected. The K-BUS KNX 24-Fold Multi-function Actuator integrates into such a system to control lighting, shutters, and other electrical loads.

6. Operation

6.1 KNX Programming

The K-BUS KNX 24-Fold Multi-function Actuator requires configuration using the KNX Engineering Tool Software (ETS). This software allows for:

• Assigning physical addresses to the device.
• Defining the function of each output channel (e.g., switching, dimming, shutter control, fan coil control).
• Linking communication objects to group addresses for interaction with other KNX devices (sensors, control panels).
• Setting parameters such as switching delays, scene functions, and shutter travel times.

6.2 Manual Override

Each output channel has a corresponding manual button on the front panel. Pressing this button allows for local control of the connected load, overriding KNX commands. This feature is useful for testing or temporary control during system commissioning or in case of KNX bus issues. The LED indicator for each channel will show its current status (ON/OFF).

7. Maintenance

The K-BUS KNX 24-Fold Multi-function Actuator is designed for long-term, maintenance-free operation. No user-serviceable parts are inside the device.

• Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
• Do not use liquid cleaners or solvents.
• Ensure that the ventilation openings are not obstructed.

8. Troubleshooting

If the device is not functioning as expected, refer to the following common issues and solutions:
