Dear CSV and mk6 experts,
ours ia a Fr5-Mk6 Alstom machine. Getting frequent alarm for the compressor inlet TC reading disagree(L86TCI). though ctif-1 and ctif-2 readings found on the screen is OK. May be there is an intermittent failure of reading in one of the TC. This alarm gets latched and we need to execute "Master Reset" to reset this alarm. while executing MR, the turbine load goes down OR up, by 1 to 2 MW, and then restores. The CTIF values are also used in CTIM-CQTC-IGV modulation- TTRX5-Trip History capture algorithms. L30FPG2L ALM also comes ON and gets reset later.
Kindly explain the reasons for this effect on LOAD and FPG low Pressure alarm. And what is input n/d means under CQTCV1 algorithm. Thanx...
