We have a GE frame6 gas turbine. For the last 3 days we have had a diagnostic alarm which is "Voter mismatch, <S> Q_C_MAO02" and also "Voter mismatch, <T> Q_C_MAO02". I couldn't find how this output is generated and what it controls. I checked the IO files but there is no device name for this output then i checked cabling diagrams but again no score. What can be the cause of it? Also can you give me information about the diagnostic alarm "TCCA Status S page xmit failure"?
