Hi! I am using a Profilux3 to control my fish system. I periodically get an error message "No connection to profilux over PAB!" accompanied by beeping. This sometimes has accompanied probe out-of-range alarms, but sometimes seems to be unrelated to any other alarm. when it flashes on the screen, nothing else is accessible through the touch screen of the Profilux3, and it's unclear how to silence the sporadic beeping via the touch screen as well.

1) Does anyone know what this error message means?
2) Does anyone know how to resolve whatever is causing the problem?

Thanks for your help
