Good day,
We are currently having issue with our MS5002B gas turbine exactelly in centrifugal compressor thermocouples. the GT is stopped and the Lub oil circulation is in service.
As mentioned in pics, some of thermocouples r good (TE 623, 626, 650,653) & the rest r out of range!!
We checked them in site and in the pannal of MARK VIe ( the entre of I/O pack), we found them approximately in the same value (22C°), but in HMI r in wrong value as they mentioned in pic.
We thought that the problem lies in the PTCCH1B pack or STCC termibal board, we changed both of them & Pb remains the same!
Please kindly assist with any info on what to do next & Thank you for your help and your patience.
