Came across an interesting scenario today while secondary injection testing some GE AKRU breakers using the TVRMS2. Has anyone ever got the error “digital link open” on the test kit while trying to test Epic MicroVeraTrips on draw-out breakers in the test position?
Seems to me like there is something wrong here and I had this happen on a couple different units. Once the breaker is in the disconnected position the error goes away and I can test with no problem. I wasn’t able to find anything in the TVRMS-2 user manual except for “Digital link open” means there is no trip unit connected (obviously).
The switchboard is equipped with the Field Programming Package which might be causing the problem. If I had to guess I would say there is a secondary pin somewhere with voltage on it that is opening the digital link.
Has anyone else come across something similar?
