Expansion Box constant yellow after power failure

[tbreza]

I have a Profilux 3.1N eX (firmware 6.29) with 2 expansion boxes (firmware 2.03). I had a recent power outage and now one of my expansion boxes shows a constant yellow and none of the probes (temp, pH, airtemp/humidity) are showing values. I have tried unassigning and reassigning the boxes as well as a PAB system reset without resolution. I have also tried to unplug the expansion 2 box for 10 seconds with no improvement. Please help with next steps. Thanks you.

Still having problems. I tried to downgrade the firmware on the expansion 2 box to 2.01. It will turn the logo color back to blue, but still no readings from the probes. I also opened the unit and tried to reset it with the button inside. Still no improvement. Could someone please help?

A solid yellow light indicates that the memory has been reset. Check to see that you can successfully assign this PAB-device to your P3 system. You should be able to see the newly added list of probes and ADC values for each new probe.

Once you have the device assigned, you should see it listed in your ProfiLux's PAB-device list. You can also try to reset your PAB-devices within GCC.

Please provide us with a screenshot of your SYSTEM settings page showing the device added and its installed FW version.

I have unassigned and reassigned several times as well as several PAB system resets. The expansion box adds just fine. There just isn't any functionality. There is a humidity/air temp, pH, and digital temp probe attached. None show any reasonable values. I downgraded to firmware 2.01 which removes the yellow logo and shows blue or red if in alarm state, but still no probe values. I currently have the firmware back to 2.03, the expansion box is assigned, and the screenshots were taken below. My other PAB devices, including another expansion box are operating normal.system.jpgsensor overview.pngconfiguration.jpgpH.jpgtemp 2.jpg

Any other thoughts? I really need to regain functionality of this expansion box as it is connected to monitor all my frag tank parameters.

I am still having a problem with this box. I had to move my other expansion box to my frag tank. I currently have this box only running a level switch on a leak detector. That seems to be working fine. I had to disable the other probes (temp, airtemp, humidity) as they were giving values of zero. Still showing a constant yellow logo.
