We have a problem in GE mark-IV control system in frame 9 gas turbine. There was not ready to start due to master protective lockout. There was voting mismatch for so many parameter, and we didn't find any clue. But after several hours after master resetting, we get ready to start and master protective lockout doesn't appear any more. But when turbine started, it again appear.
Please give us some idea what are the parameter do we need to monitor to resolve the problem.
Thanking you
