Hi all!
Very strange issue, I have a customer that reports a trip of our safety relay (Schneider Preventa) and subsequently main breaker trip (cause by safety relay).
The failure comes periodically every 7days, 6 hours and 52 minutes. Short enough to trip our safety relay, but not long enough for any of our other safety signals (Siemens 3RH2131-1JB40) to trip.
We replaced our Preventa unit, and error consists at the expected times.
We now know there is another safety unit in place, which I suspect causes the issue. Also a Schneider unit, XPSMCMCO000EM + XPSMCMCP0802 + 2 XPSMCMMX0802. I am not familiar with this particular device.
Has anyone run into where the above system, periodically opens the outputs for a very very short amount of time?
Sorry, hard to explain what I am seeing, as I am unsure what the heck is going on!
