We've got a dual fuel 7EA DLN gas turbine, and we just finished a hot gas path inspection. We also replaced all of our electro-mechanical generator protection relays with solid state relays. When we started up yesterday, immediately after the breaker closed, we got a slew of diagnostic alarms and the GT tripped. The indicated alarm trip was L86TXT. All of our cards have status lights that say that they are good. Here is a list of the diagnostic alarms we received:<pre>
R 0324 No arcnet communication with R
R 0325 No arcnet communication with R
T 0326 No arcnet communication with R
R,S,T 1708 TCE1 Loopback, relay, PTR1
R,S,T 1713 TCE1 Loopback, solenoid, ETD1/SOL1/MTSV
R,S,T 0312 LCC <unused> #8
R,S,T 1251 TCQA 4-20ma output disagrees w/ref CH.8
R,S,T 1696 TCE1 TMR check trouble, ETR1
R,S,T 1697 TCE1 TMR check trouble, ETR2
C 2701 Voter mismatch, <T> L14h_ZE</pre>
Any suggestions on where to start with this?
Thanks,
Jeff
