AL-WS-DR2 hardware / firmware versions
Isolator
Two adjacent AL-WS-DR2 in CCT or 8x LED mode, might have enough crosstalk - to cause an "off" LED to glow or flicker
A ferrous isolator is available to fix this. A kind of Tin Hat
Set the device between two DR2, see photo for exact location:
Version 3 of our DR2 product offers many improvements over the previous versions.
It is called AL-WS-DR2F informally and AL-WS-DR2 v10 officially
there are 16k and 32k versions

The Driver mode is determined in most cases automatically. The mode can be overruled by the DALI master using DALI commands (see data sheet)
There is one case that cannot be determined automatically. An 8 LED fixed color installation will power up as a CCT color installation causing the lights to operate at 1/2 power. If DALI is not available to change this mode - then the installer can force this setting by disconnecting one LED, power cycle the AL-WS-DR2, then reconnect the LED. The DR2 will operate in 8x mode.
The N-Way input can be controlled by DALI commands from the DALI master - see the data sheet. Here is a summary.
DALI code
| N-Way input mode
| AL-WS-DR2
| AL-WS-DR2F
|
0
| Three way Rocker
| default
| auto detect if switch ON for 45 seconds
|
1
| Three way Momentary
| detected on first use
| auto detect if switch press briefly 5 times
|
2
| Split LED
| yes
| allows LEFT controlled by Main switch, Right by N-Way must also set Driver as Split mode

Fan / Timer
|
no
| auto set if motor detected ( Times set by DALI ) Left (LED) follows switch Right (LED or FAN) control a) follows LEFT switch after 90 seconds, stays on 10 minutes. b) follows N-Way rocker with 10 minute auto off. c) each N-Way momentary press adds 5 minutes then auto off

| Night
| no
| N-Way active High input causes: a) Split Driver: Right LEDs on with 10% Main switch operates normally
|
5
| PIR
| yes RIght is ON Left is switched
| N-Way active High input causes both LEDs on at DIM level .
