How to locate and repair a CCT Fault
LEDs attached to a DR2 do not change color
a) moving the slider while the momentary is pressed does not change color ( it dims)
b) in ZWD, when the device is expanded - the LED Driver mode is not "ALL CCT"

Check LED connections
|
Visit Advanced
click on the radio button next to the "short" address of the switch
Click on Query Status
Check that the Left and Right status are OK
If either is "Bad" then there is an open wire to the LEDs - Right is warm, Left is cool. Repair the wire
|
Firmware version 54 or later
| The number of LEDs on the cool and white string must be the same. Check this first.
| Expand the AL-WS-DR2 switch
on the bottom - there are two status boxes with "height" Left and Right.
Insure that the numbers are the same. Each P023R6 is 3 units - so if there are 12 in the circuit, then this means there are 4 fixtures of 3 units each.
If the numbers are not the same, then enter the physical number into both sides, Click on Re-Calibrate
CCT will not be possible until the two sides match
|
Firmware 53 or earlier
|
| In Advanced, check the button next to the switch number, click on "Reset",turn the switch ON, wait for recaibration
CCT will not be possible until the two sides match |
Test the DR2
| Exchange the LED left and right
| Click on Reset in Advanced to force a retest see if the "bad' output stays on the same side
|
