We have a Frame 6 gas turbine (simple cycle) with MARK IV control system. Suddenly our CRT monitor freezes but machine was running normal with load. Several time we cut off and on the power supply of CRT. Each time it showed the normal display with freezed values. Then we reinitialized C controller then everything was normal. But all counters such as running hour was stopped and again started after C controller reset. There was a 125V DC ground alarm before the problem started.
After C controller reset I found
S125P = 40V,
S125N = -75V
Why C controller stopped and is it related to 125V DC Ground?
