Dear everyone,
Our Gas Turbine, frame 6b with Mark VI control was shutdown normally 2 days ago.
Mechanical requested we open the IGV to carry out maintenance work.
The IGV was opened and was okay, but when we closed it after their inspection, the physical angle was more than the reference and the feedback, kindly assist.
Reference Feedback Actual
34 33.6 43
56 55.6 63
87 86.4 out of range.
88Hq and 88Qa were Power down but the physical igv is still 43degree.
I have read some thread on IGV but could not get what I wanted.
Thank you great people if thus forum, waiting patients for the solution.
