HI,
I would like to seek your expertise and advise on how to logic work on the exhaust temperature trip logic.
I would like to understand how the philosophy and algorithm of the average calculation as given on the TTXSPV4 block .
The trip happen when both TTXD 9 and 12 value spike in millisecond as good value to 1300F. No diagnostic recorded for any failure of TC probe nor the MarkVIe module. No high spread trip appear just Exhaust over temp trip directly.
Alarm event.
G1.L4T Master Protective Trip
G1.L30TXA_ALM EXHAUST TEMPERATURE HIGH
G1.L86TXT_ALM EXHAUST OVER TEMPERATURE TRIP
G1.L30TXA_ALM EXHAUST TEMPERATURE HIGH
Looking on the block EX_TMP_MD_7E, it is masked but the block TTXMV4_1 is visible though to understand the algorithm of it is confusing. I will attached the active block and trip log trend for your reference.
Question is:
1. How the TC affected the trip if calculation is average, does it have a separate logic that detect the TC high temperature against its threshold.
2. If only one (1) TC went on 1300F, does the machine will trip as well?
Looking forward to expertise reply. Thank you.
