GHL optical level sensor for my ATO stopped working

[xenon]

While I took these screenshots the sensor was not touching water. I rebooted the controller and it made no difference. I made 100% sure the mini-din was connected in the proper port.

I am using the dosing pump#1 to top-off RO/DI water.

Problem solved.

I upgraded to firmware 4.05 and it works now.

Weird.

if you have miss matching software to firmware the level sensors will not function correctly same as temp

This happened to me again today and I simply unplugged my controller so that it would reboot and the problem was solved.

All timeout errors cleared?

there is one method to check if the sensor is working or not:
watch "current sensor states" (either in ProfiLuxControl or on the device directly - menu diagnosis) and put the sensor into the water and lit it again manually

if the displayed states don't show te expected result then it is possible that the sensor is damaged - in this case contaxct your retailer

using a socket state to determine if a sensor is defective or OK is NOT making sense because other settings (like timeout) may influence the socket state!

While testing, I found that if my optical sensor was very close to the bottom of the tank, it "reflected itself" for lack of a better term and would stop working. Once I lifted it a half inch or so it was fine.
