If you see a dimmer flash GREEN & PURPLE :
It's tried to ramp in auto calibration and missed it (didn't do it properly) just press the ON button and it should run through a calibration again - essentially means that bulbs aren’t great but should work if not then may need to change or set to on and off if they have a neutral .
LED indicator during auto calibration: Blinking Green – dim level ramping phase (calibrating)
Alternating Green and White – Stabilisation phase (detects flicker and eliminates)
Alternating Green and Magenta/purple – auto-calibration has failed, so it seems as the calibration has failed as the bulbs may not be 100% compatible, You will most likely need to perform a manual calibration. The dimmer will try to stabilise the load by running multiple tries from high to low for trailing edge configuration, then if unsuccessful, it will repeat the process for leading edge mode too.
If both trailing and leading edge mode stabilisation have failed, the dimmer abandons the auto-calibration process by going into calibration error state. To exit the auto calibration error state, the user can either a) press a button on the dimmer.
b) power cycle the device (a and b both restart the auto calibration) or c) link the dimmer to the Link+ and either re-initiate the auto calibration or set the calibration values manually.
Note that once an auto calibration has been initiated, the process will persist between power cycles until the dimmer either succeeds or fails.
The lamps under auto calibration will go on and off depending on the process phase, which is expected behavior.
If all the above fails then unfortunately the new firmware has detected in compatible lamps and they will need to changed.
There were cases on V4 firmware where some incompatible lamps appeared to function properly, but these lamps could lead to device failures. The V5 Firmware vastly improves performance, stability and is more robust which helps uncover and identify lamps that can cause this issue. Your case is rare, but the new firmware has identified that your bulbs aren't ideal from a compatibility stand point.
The green flash on the the LED indicator an indication of a Slave dimmer.This is a new behavior and we understand that some users might not like it but this helps us moving forward supporting our customers in the right way to identify issues with specific devices and also to have a better log on our system .
So this was written in the software when the firmware was deployed to dimmers to make it easier for us to troubleshoot and commission installs.
The Green light only appears for a split second or so before the dimmers goes ON/OFF and this cannot be disabled on the slave units I am afraid. This is part of the new firmware for slave dimmers now. The slave dimmers are now classed as Remotes, so any future Lightwave Remote control will behave the same as the software will be written in the same way.
