Product Usage Instructions

Operation

1. Set DALI Address Quantity:
   • Long press M for 2s to prepare for setting DALI address quantity.
   • Use the or key to switch between 1/2/3/4 DALI address quantity (1CH, 2CH, 3CH, or 4CH).
   • Short press M key or wait for a timeout of 10s to exit DALI address quantity setting.

DALI Address Quantity Setup Explain

• When set 1 DALI address, Ch1, Ch2, Ch3, Ch4 will have the same DALI address.
• When set 2 DALI address, Ch1 and Ch3 will have the same DALI address A, Ch2 and Ch4 will have the same DALI address A+1.
• When set 3 DALI address, Ch1 will have DALI address A, Ch2 will have DALI address A+1, Ch3 will have DALI address A+2, and Ch4 will have no DALI address and no output.
• When set 4 DALI address, Ch1 will have DALI address A, Ch2 will have DALI address A+1, Ch3 will have DALI address A+2, and Ch4 will have DALI address A+3.

For example, if the starting DALI address is 32:

• When DALI address quantity is 1CH, the dimmer will occupy 1 DALI address (address 32).
• When DALI address quantity is 2CH, the dimmer will occupy 2 DALI addresses (addresses 32, 33).
• When DALI address quantity is 3CH, the dimmer will occupy 3 DALI addresses (addresses 32, 33, 34).
• When DALI address quantity is 4CH, the dimmer will occupy 4 DALI addresses (addresses 32, 33, 34, 35).

Features

• 4 channel constant voltage DALI LED Dimmer with digital display, 5A per channel.
• 1-4 DALI address quantity is selectable, 4 channel work separately.
• In accordance with DALI standard protocol IEC 62386-102, IEC 62386-207 and in compliance with DALI products from other international incorporation.
• DALI address can be manually assigned and shown in digital display or automatically assigned by DALI master.
• PWM digital dimming, standard DALI logarithmic dimming curve.
• PWM frequency 1000/2000/4000/8000Hz selectable.
• Over-heat / Over-load / Short circuit protection, recover automatically.
• With fast self-testing function.

Operation

Set DALI Address Quantity

You need set DALI address quantity according to applications requirement for the first time.

• Long press M for 2s, prepare for set DALI address quantity.
• Short press ◀ or ▶ key to switch between1/2/3/4 DALI address quantity (”1CH”,”2CH” ,”3CH” or ”4CH”).
• Short press M key or timeout 10s, quit DALI address quantity setting.

DALI address quantity setup explain

• When set 1 DALI address, Ch1,Ch2,Ch3,Ch4 will be the same DALI address.
• When set 2 DALI address, Ch1,Ch3 will be same DALI address A, Ch2,Ch4 will be same DALI address A+1.
• When set 3 DALI address, Ch1 will DALI address A, Ch2 will DALI address A+1, Ch3 will DALI address A+2, Ch4 no DALI address and no output.
• When set 4 DALI address, Ch1 will DALI address A, Ch2 will DALI address A+1, Ch3 will DALI address A+2, Ch4 will DALI address A+3.

For example, the start DALI address is 32

• When DALI address quantity is ”1CH”, the dimmer occupy 1 DALI address and address is 32.
• When DALI address quantity is ”2CH”, the dimmer occupy 2 DALI addresses and address is 32,33.
• When DALI address quantity is ”3CH”, the dimmer occupy 3 DALI addresses and address is 32,33,34.
• When DALI address quantity is ”4CH”, the dimmer occupy 4 DALI addresses and address is 32,33,34,35.

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 between1000Hz(“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, DALI address quantity is 4, PWM frequency is 2000Hz.
• 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.
