4.1.1 Unicast Mode

• X Setting: 0-6
• Y Setting: 0-9
• Address Range: DALI unicast address 00-63.
• Example: If X=5, Y=4, Address value = 5 * 10 + 4 = 54.
• Push Button Actions:
  • Short press K1, K2, K3, K4: Turn on/off the light.
  • Long press K1, K2, K3, K4: Increase or decrease brightness.

4.1.2 Group Mode

• X Setting: 7
• Y Setting: 0-F (Hexadecimal)
• Address Range: DALI group address 0-15 (corresponds to 70-7F).
• Example: If X=7, Y=E, the group address value is 14.
• Push Button Actions:
  • Short press K1, K2, K3, K4: Turn on/off the light.
  • Long press K1, K2, K3, K4: Increase or decrease brightness.

4.1.3 Scene Mode

• X Setting: 8
• Y Setting: 0-F (Hexadecimal)
• Address Range: DALI scene 0-15 (corresponds to 80-8F).
• Example: If X=8, Y=5, the scene value is 5.
• Push Button Actions:
  • Short press K1, K2, K3, K4: Recall the scene.
  • Long press K1, K2, K3, K4 (2 seconds): Turn off the scene light.

4.1.4 Broadcast Mode

• X Setting: 9
• Y Setting: 0-F (Hexadecimal)
• Address Range: Broadcast address (corresponds to 90-9F).
• Push Button Actions:
  • Short press K1, K2, K3, K4: Turn on/off the light.
  • Long press K1, K2, K3, K4: Increase or decrease brightness.

5. Maintenance

The DA-4S DALI Dimmer requires minimal maintenance. To ensure optimal performance and longevity:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the device to extreme temperatures or humidity outside its specified operating range (-20°C to +50°C).
• Do not use harsh chemicals or abrasive cleaners.
• Ensure proper ventilation if installed in an enclosed space.

6. Troubleshooting

If you encounter issues with your DA-4S DALI Dimmer, consider the following common troubleshooting steps:

• No response from lights:
  • Check all wiring connections to ensure they are secure and correctly installed according to the wiring diagram.
  • Verify that the DALI Master and Bus Power Supply are functioning correctly.
  • Confirm the DALI address settings (X and Y rotary switches) are correct for the desired mode (Unicast, Group, Scene, Broadcast).
  • Ensure the push buttons are correctly wired and functional.
• Incorrect dimming behavior:
  • Recheck the DALI address settings.
  • Ensure the DALI LED drivers are compatible and properly configured.
• Device not powering on:
  • Verify that the DALI bus is providing power to the device (4mA@16V static current).
  • Check for any loose connections or damage to the device.

If the problem persists after these steps, contact customer support for further assistance.
