Dear all,
We have one problem in our control system Mark IV+ for GE frame 9 Gas turbines in DEWA- Dubai. I hope that somebody is having idea or can advise us.
When turbine is in shutdown condition there was no alarm, but after giving start command the following alarms are appearing:
* Master start up protective lock out.
* diagnostic alarms for <T> controller voting mismatch for so many parameters (L4QA, L4QB, LTN_MAX, L4X1, L20FG1X, L94X1, FQ2, FSRSR, FPRG, FSRS1, DSR2, FSROUT,....) and so many other diagnostic alarms all for <T> controller only.
We replaced already the HMPJ (processor module) of <T> controller with new one, but still problem is persisting. After reaching to FSNL we restarted the <T> controller, and then all alarms are resetting. But during every start-up the same problem is happening.
Waiting for your valuable ideas.
Best regards,
