Dears,
We have frame 5 gas turbine for power generation with Mark 5 control system. But after the shut down the following diagnostic alarms are coming continuously. Can anybody can suggest what are the possible reasons? and what check points we have to carry out resolving these issues? because first time we are facing these type of problems. Diagnostic alarms are.
1. IOMA power supply out of limits N15.
2. TCE1 power supply out of limits DCOM.
3. Voter mismatch <T> L33FP28.
4. TCQA P125-N125 over voltage.
5. TCE1 breaker1 close time out of limits.
6. Voter mismatch<S>CPD.
7. TCQA Ma short circuit voltage too high (these alarms repeating three times).
We checked all the R, S, T & C status in LCC display. S showing A7, but R, T& C LCC display toggling between "A7" & "DCC ERROR".
Your suggestions are highly appreciated regarding this matter.
