Wiring Diagram

Caution : Please carefully ensure all wire connections and polarities are correct and secure before applying power, otherwise this controller will be damaged.

• DT-B connect with DALI master
  

• **DT-B connect with AC push switch

Indicator status:
When the dimmer is working normally, the LED indicator light is green.
When the internal temperature of the dimmer is too high (≥120℃) or the load exceeds maximum power, the LED indicator light is red, after removing the fault, the LED indicator light return green.
When the dimmer receives DALI signal, the LED indicator light ashes once.

Note:

1. DALI interface and AC PUSH interface are compatible, DALI and AC PUSH can only be connected to one, not at the same time. When connecting to the AC PUSH switch, note that the re wire (L) and zero wire (N) are connected to DA1 and DA2 respectively, and cannot be connected to DA1 or DA2 at the same time.
2. When calculating the maximum number of load lamps or drivers, the input power or input current parameters of a single lamp or driver must be used, the output power parameters can not be used.
   In addition, the maximum surge current of the dimmer is 65A, the sum of surge current of multiple dimmable LED drivers should not exceed 2 times. otherwise, the product will be overloaded and damaged.

Minimum brightness setting

Minimum brightness setting
The minimum brightness of the device can be set or deleted by press the Min brightness set key on the dimmer.

• Recall minimum brightness :
  Short press the Min brightness set key on the dimmer, LED indicator ash one, the light output the minimum brightness.

• Setting minimum brightness:
  Adjust the brightness to a desired minimum level, then press and hold down the Min brightness set key 2s until the LED indicator ash one, the current brightness is set as the minimum brightness.
  The light can only be dimmable between this minimum brightness and maximum brightness.

• Delete minimum brightness:
  Adjust the brightness to maximum level, then press and hold down the Min brightness set key 2s until the LED indicator ash one, the minimum brightness setting is deleted.

Push-Dim Function

The provided Push-Dim interface allows for a simple dimming method using commercially available non-latching(momentary) wall switchs.

• Short press:
  Turn on or off light.

• Long press (1-6s):
  Press and hold to step-less dimming,
  With every other long press, the light level goes to the opposite direction.

• Dimming memory:
  Light returns to the previous dimming level when switched off and on again, even at power failure.

• Synchronization:
  If more than one controller are connected to the same push switch, do a long press for more than 10s, then the system is synchronized and all lights in the group dim up to 100%.
  This means there is no need for any additional synchrony wire in larger installations.
  We recommend the number of controllers connected to a push switch does not exceed 25 pieces, The maximum length of the wires from push to controller should be no more than 20 meters.

DALI address assigned by DALI masters

DALI address can also be assigned by DALI Master controller automatically.
Please refer to user manuals of compatible DALI Masters for specic operations.

Safety & Warnings

• DO NOT install with power applied to device.
• DO NOT expose the device to moisture.
