Application Scenarios
How to Install & Configure This DALI Controller
- Wiring: Connect the two wires from your DALI bus to the corresponding terminals on the back of the E6-DA1 panel. DALI is not polarity sensitive.
- Address Setting: Before final mounting, use a small flathead screwdriver to set the control address via the two rotary dials (X and Y) on the back.
- - For Unicast Control (0-63): Set dial 'X' to a value from 0-6 and dial 'Y' to 0-9. The address is calculated as (X * 10) + Y. For example, X=4 and Y=0 sets address 40.
- - For Group Control (0-15): Set dial 'X' to 7. The address is then determined solely by dial 'Y' (0-15). For example, X=7 and Y=5 sets group address 5.
- - For Broadcast Control: Set dial 'X' to 8 or 9 to control all devices on the DALI bus simultaneously.
- Mounting: Securely install the panel into a standard 86x86mm European-style wall box.
- Operation: Turn the knob clockwise to increase brightness and counter-clockwise to decrease. To turn the lights off completely, rotate the knob fully counter-clockwise until it clicks.
- Ensure the DALI system has a dedicated DALI power supply installed on the bus.
- This device is a controller and must be connected to a DALI bus with DALI drivers or ballasts.
- Do not apply mains voltage directly to the DALI terminals.

Frequently Asked Questions
Q: Does this DALI knob panel need its own power supply?
A:No, it is powered directly by the DALI bus, which greatly simplifies wiring and installation. Your DALI bus itself will require a DALI power supply.
Q: Can I control a single light fixture with this panel?
A:Yes. By setting the panel to Unicast mode using the dials on the back, you can assign it to control any single DALI address from 0 to 63.
Q: How do I control a group of lights, like all the downlights in my kitchen?
A:Set the panel to Group mode (X dial to 7) and use the Y dial to select one of the 16 available group addresses (0-15) that your lights are programmed to.
Q: What is the difference between this rotary dimmer and a DALI push-button switch?
A:This panel's rotary knob provides smooth, continuous dimming for fine-tuned brightness control, whereas a push-button switch typically offers stepped dimming or simple on/off functionality.
Q: Is this E6-DA1 controller compatible with DALI drivers from other brands?
A:Yes, it fully complies with the DALI standard IEC62386, ensuring broad compatibility with other certified DALI drivers, ballasts, and devices.
Q: How do I turn the lights completely off?
A:Simply rotate the knob fully counter-clockwise. You will feel and hear a distinct "click" as the switch engages, turning the connected DALI lights off.
Q: What kind of wall box is required for installation?
A:The E6-DA1 is designed to fit into a standard 86-style square wall box, common in Europe and other regions.
