Mark-V T-core I O status on LCC displaying
(4) **** - A1
(15)**** - A1
T-core should be in A7 status but it has stuck in A6 status.
There was lightning and thunderstorm yesterday in our area during which the machine tripped. There was no tripping alarm except - Generator breaker tripped from TCP.
After thorough check of process alarm, we started the machine but starting device tripped immediately on giving start command showing machine coasting down (with unusually TNH-RPM showing 50 RPM on the <I> station screen). On further check we found one speed sensor has got problem.
We reboot the Mark-V cores. After reboot the T-core status stood on A6 status, while all other cores (C, R & S) are on A& status.
We replaced TCEA (Loc-5) in P core and TCDA (loc-3) in QD1 core but could able to rectify the problem
Please suggest remedial at the earliest.
