Operation

Set DALI Address Manually Via Buttons

1. Press and hold down any of the two buttons until the numeric digital display flashes, then release the buttons.
2. Click any of the two buttons once to select a digit, and click again to change the digit until the desired DALI address appears. Click the first button to set the “tens” position and the second button to set the “units” position. The address can be set from 00~63.
3. Then press and hold down any of the 2 buttons until the numeric digital display stops flashing to confirm the setting.
   Note: DALI address can be manually assigned from 00-63-FF, by factory defaults, no DALI address is assigned for the driver, and the display shows . Setting the DALI address will reset the dimmer to factory defaults.

DALI Address Assigned by DALI Masters.
DALI address can also be assigned by the DALI Master controller automatically, please refer to user manuals of compatible DALI Masters for specific operations.
Note: The digital display will show AU when the DALI master is assigning addresses.

Set DALI Address Quantity.

1. Press and hold down both of the two buttons until the numeric digital display flashes, then release the button.
2. Click the first button to select “1A”, “2A”, “3A” or “4A” which means 1/2/3/4 DALI addresses.
3. Then press and hold down any of the 2 buttons until the numeric digital display stops flashing to confirm the setting.

For example, when we set the DALI address to 00:
When selecting 1A, all 4 channels load will be the same address 00 and controlled simultaneously.
When selecting 2A, channels L1&L3 will be same address 00, channel 2&4 will be same address 01.
When selecting 3A, channels L1&L4 will be addressed 00, channel L2 will be addressed 01, and channel L3 will be addressed 02.
When selecting 4A, channel L1 will be addressed 00, channel L2 will be addressed 01, channel L3 will be addressed 02, and channel L4 will be addressed 03.
Note: The channels with the same address will be controlled simultaneously, and the channels with different addresses will be controlled separately.

Reverse-phase control (trailing edge)

Set the minimum dimming brightness point.
The factory dimming range is 1%~100%, but the 1% can be re-set as below:
Operate the DALI master to dim a load of L1 to a brightness you want, then press and hold down the Min. set button until the light flashes, which means the minimum point is set at this brightness now. You can not dim lower than this brightness point. The minimum point will be covered by repeating that.
How to reset it to factory defaults: dim up the Load of L1 to 100%, then press and hold Min. set button until a load of L1 flashes.
Note:

1. The dimming range of this dimmer is 1%-100%, but some load types may flicker when dimmed to 1%, thus a minimum brightness shall be set higher than 1% to avoid flickering during the dimming process.
2. Whatever the DALI address quantity is set as 1A, 2A, 3A, or 4A, the minimum brightness shall be set or reset only by adjusting the Load L1 output brightness and pressing Min.  set button. Once the minimum brightness is set, all 4 channels’ load can not be dimmed below this value.

Wiring Diagram

1. With DALI bus
   This phase dimmer adopts trailing edge dimming (reverse phase control), the dimming range is 1%~100%, please make sure the connected loads support reverse phase control. Please refer to the user manual of the load or consult the supplier of the load.

2. With AC Push
