Hello,
Operating a frame 7EA with the Mark IV control system. While loading the unit, the <S> processor indicates several diagnostic alarms once the IGV angle increases beyond the 57 degree position. The diagnostic alarms are voting mismatch <S>, CSRGV, FSRN, FSRN, FSROUT, FSRACC, FSRS1, FSR2. The LVDT feedback position and voltages look good across all 3 processors, but the reference CSRGV and FSR2 are affected by the issue that is being experienced.
When selecting temperature control off at or near base load, all diagnostic alarms will eventually clear, but once reselected, the list of diagnostics reoccurs and the same conditions exist.
With <R> and <T> controllers indicate the IGV's in temp control and are approximately 77 degrees(CSRGV) and FSR2 indicates 66%, the <S> indicates 84.0 degrees for CSRGV and the GCV reference FSR2 indicates 0.5%.
Looking for any troubleshooting advice.
Thanks
