PX80 static switch fault

[BillP]

Good Day, 

I am having an issue with a PX 80KVA, the unit is saying the static switch is faulty, the static switch was replaced with a new one from APC but the fault remained, it is also saying in the logs "communications established" every few minutes, could this be one or both intelligence module(s) are faulty?

Hi, nobody answer to you? I experience the same on symetra PX: static by-pass module switch fault" alarm.

I open and close again the Q5 breaker ( static by-pass and the alarm disapear. But i didn't receive an answer from Apc explained this..
