GT Exhaust temperature feedback and protection block that is used to calculate the TTXM and other protection signals is a bit confusing for me. What does this mean with the array, and where it is using this array? Is their any pairing in GT exhaust thermocouples and if so then what is their use in above mentioned block?

 

Cleverly hidden at the far right edge of the Menu bar at the top of every control.com webpage is a 'Search' feature that can be used to quickly search the control.com Archives for past threads with any search terms (using the Search Help function the first couple of uses is highly recommended).

Typing the following term into the 'Search' field then clicking the "?" To the right of the field turned lots of relevant occurrences:

+TTXMV4

This was one of the most recent threads, but there are many other very relevant threads--many with people expressing gratitude and satisfaction with the quality of response(s).

It's the feedback about the usefulness (or not, as the case may be) that makes control.com such a useful site. There is more than a decade's worth of GE-design heavy duty gas turbine and -control-related topics--many having been covered in detailed multiple times.

If you still require additional clarification, we are here to try and help.

Let us know if you find the past threads helpful--it helps others know if the information was helpful (or not, as the case may be).

Good reading!
