Anybody have the doc which details GE's TTSA, the resistor board that is used when servo valves are used as trip solenoids? Example would be the 20TV as the trip/dump for IGVs.
I believe there are details of the TTSA card in the Mark VI (not the Mark VIe) System Guide, GEH-6421, Vol. II. It wasn't in early revisions of the manual, but did appear in later revisions.
Consistently inconsistent, as a former colleague used to say....
you can find information on this card in GEI-100560V, page 50. Or as CSA tells it is in the 6421 manual, the revision I have is "P" and its on page #425. If you don't have the manuals, sign up for the GE controls connect site and you can get them from there.
