Good evening everyone in the Great house.
One of our gas turbine fails to ratchet after shutdown and according to the operator in charge they have boxed the unit till after 48hours to return to cool down it self then we will now troubleshoot. So my question now is as an Instrumentation and control personnel what are the things that might caused the problem and after checking the starting clutch solenoid valve which resistance values is okay.
The signal name of the alarm that comes up from the HMI was "G2L30HRX1" Ratchet trouble.
Thanks for usual cooperation
