Skydance DA1-S DALI LED Dimmer User Manual

1. Introduction

The Skydance DA1-S is a constant voltage LED DALI dimmer designed for single-color LED strips. It features 1 DALI address and 1 channel constant voltage output. This device is DALI-2 certified, complying with IEC 62386-101, 102, and 207 standards, ensuring compatibility with other international DALI products. It supports PWM digital dimming with a standard DALI logarithmic dimming curve and offers three selectable PWM frequencies. Additionally, it includes a DALI signal input port that supports AC push switch dimming and provides over-heat/short circuit protection with automatic recovery.

2. Safety Information

• DO NOT install with power applied to the device. Ensure all power is disconnected before installation or maintenance.
• DO NOT expose the device to moisture or operate in wet environments.
• Ensure proper wiring according to the diagrams to prevent damage to the device or connected components.
• This device is designed for constant voltage LED strips. Do not connect to other types of LED loads.
• In case of malfunction, disconnect power immediately and consult a qualified technician.

5. Installation and Wiring

Mechanical Structures and Terminals

The DA1-S features clearly labeled terminals for input, output, DALI input, and a SET key. The DALI bus does not require distinguishing between positive and negative polarity.

Wiring Diagram: DALI Master Connection

To connect the DA1-S with a DALI master, follow the diagram below. Ensure the DALI bus power supply is connected correctly.

Wiring Diagram: Push Switch Connection

The DA1-S also supports dimming via an AC push switch. Connect the fire wire (L) and zero wire (N) of the AC 100-240V input to DA1 and DA2 respectively. Note that the DALI interface is compatible with the push switch interface, but DALI and push switch can only be connected to one, not at the same time.

6. Operation

DALI Control

The DALI address for the DA1-S is automatically assigned by the DALI Master controller. For specific operations and advanced settings, please refer to the user manuals of your compatible DALI Master.

PWM Frequency Setting

The DA1-S allows you to set the PWM frequency using the SET key. Short press the SET key to cycle through the three available frequencies:

• 2KHz: Indicator blinks once.
• 8KHz: Indicator blinks twice.
• 16KHz: Indicator blinks three times.

Higher PWM frequencies generally result in lower output current and higher power noise but are more suitable for cameras (no flickers for video recording).

Push Dim Function

The Push-Dim interface provides a simple dimming method using commercially available non-latching (momentary) wall switches.

• Short press: Turns the light on or off.
• Long press (1-6s): Press and hold to achieve stepless dimming. With every other long press, the light level will change in the opposite direction (e.g., dimming up then dimming down).
• Dimming memory: The light returns to the previous dimming level when switched off and on again, even after a power failure.
• Synchronization: If multiple controllers are connected to the same push switch, perform a long press for more than 10 seconds. The system will synchronize, and all lights in the group will dim up to 100%. This eliminates the need for additional synchrony wiring in larger installations. It is recommended that the number of controllers connected to a single push switch does not exceed 25 pieces, and the maximum length of wires from the push switch to the controller should be no more than 20 meters.

7. Maintenance

The Skydance DA1-S LED Dimmer is designed for reliable operation with minimal maintenance. To ensure its longevity and proper function:

• Keep the device clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid exposing the device to extreme temperatures or humidity.
• Regularly check wiring connections to ensure they are secure and free from damage.
• Do not attempt to open or repair the device yourself, as this may void the warranty and pose safety risks.

8. Troubleshooting

LED Indicator Behavior

The LED indicator on the DA1-S provides visual feedback on its status:

• Always Green: When the controller is powered up, the LED indicator is always green, indicating normal operation.
• Blinks Once for Each DALI Signal Frame: The LED indicator blinks once for each frame of DALI signal received, confirming active DALI communication.
• Flashes Green Continuously: If the controller is faulty, the LED indicator will flash green continuously. This indicates an internal error or malfunction.

General Troubleshooting Steps

• No Light Output: Check power supply connections, ensure the LED strip is correctly wired, and verify the DALI master or push switch is functioning.
• Incorrect Dimming: Ensure the DALI address is correctly assigned (if using DALI master) or the push switch is properly connected and functioning. Check the selected PWM frequency.
• Over-heat/Short Circuit: The device has automatic protection and recovery. If this occurs, disconnect power, check for any short circuits in the wiring or load, resolve the issue, and then reapply power.

9. User Tips

• For optimal performance and to avoid flickering, especially when recording video, consider using a higher PWM frequency (8KHz or 16KHz).
• When using the push dim function with multiple controllers, remember to perform the 10-second long press for synchronization after initial setup or if synchronization issues arise.
• Always ensure the power supply voltage matches the input voltage range of the DA1-S (12-48VDC) and that the connected LED strip is constant voltage type.
