Operation

Output current setting

• Please select the correct current firstly when the LED load is disconnected.
• Long press M and ◀and◀ key in the same time for 2s, prepare for setup output current.
• For DA4-C(150-500mA): short press ◀ or ▶ key to switch 150mA(“C15”), 200mA(“C20”), 250mA(“C25”), 300mA (“C30”), 350mA(“C35”), 400mA(“C40”) , 450mA(“C45”) or 500mA(“C50”).
• For DA4-C(350-1200mA): short press ◀ or ▶ key to switch 350mA(“C35”), 500mA(“C50”), 600mA(“C60”), 700mA(“C70”),800mA(“C80”), 900mA(“C90”) , 1050mA(“CA5”) or 1200mA(“CC0”).
• Press M key or timeout 10s, quit output current setting.

Setting the light type

• The first time you use it, you need to set the light type according to your application needs.
• Press the M button for 2 seconds to set the light type.
• Press the ◀or ▶ key to switch between the single color (“C-1”), dual color (“C-2”), RGB (“C-3”) or RGBW (“C-4”) light type.
• Short press the M button or timeout for 10 seconds to exit the light type setting.

Light type setting instructions:

• When setting C-1 type, DT6 dimming, 4-channel output is the same.
• When setting C-2 type, DT8-TC, 3/4 LED channel and 1/2 LED channel output is the same. When setting C-3 type, DT8-RGB, the 4th channel does not output.
• When setting C-4 type, DT8-RGBW, 4 channels are output independently.

Set DALI Address via buttons

• Long press ◀ or ▶ key for 2s, prepare for set the start DALI address, then press ◀ or ▶ key to set the start DALI address.
• Short press M key or timeout 10s, quit start DALI address setting.
• The start DALI address can be manually assigned from 00-63-FF.
• by factory defaults, no DALI address is assigned for the dimmer, and digital display shows “AFF”.

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 specific operations.
• The digital display will show “AAU” When the DALI master is assigning address.
• After address is assigned, the digital display will show the start DALI address”Axx”, xx is from 00 to 63.
• Using DALI master assign address may result in discontinuous address, the digital display will show the start DALI address”Uxx”.

Set PWM frequency

• Long press M & ◀ key for 2s, prepare for set PWM frequency.
• Short press ◀ or ▶ key to switch between 1000Hz(“F10”), 2000Hz(“F20”), 4000Hz(“F40”) or 8000Hz(“F80”). Higher PWM frequency, will cause lower output current, higher power noise, but more suitable for camera (No flickers for video).
• Short press M key or timeout 10s, quit PWM frequency setting.

Restore factory default parameter

• Long press ◀ and ▶ key for 2s, restore factory default parameter, display ”RES”.
• Factory default parameter: no DALI address is assigned, DT8-RGBW, PWM frequency is 4000Hz.
• Long press M & ▶ key for 2s, enter fast self-testing, the output channel will be on orderly then all on.

Safety & Warnings

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