GE Mark VIe - Trying to change a TMR setup from a 0-5VDC to a 4-20mA transmitter..
Well, I am not sure about that. Examining the last attachment of GEH-6721G, it appears that the TBAI card is provided for the exact function of sharing single 4-20mA signals across all 3 controllers. Also if memory serves there were specific I/O cards for HART, but I'm not sure that's your...

GE MarkV
If you can use the existing EEPROM, U9 from memory, match the and hardware jumpers on the new card. I don't believe you should need to download anything. BUT I could easily be mistaken.

Flashing LEDs not in unison in "R" processor

LM6000-PG Speed Switch Fail to Close
Can you use your Bentley software(System 1) to get the trend from the keyphasor speed compare to all your speed inputs on the low speed shaft, they should be in your trip log. I believe if the safeset had sheared you would be getting zero generator speed. Likely it looks like a faulty key phasor
