Bob and others
I need your help in following / understanding the attached diagram.
According to the folks at trio the 5 and 6 leads from the trio servo are
wired to the commons of the dpdt relay. The purpose of this set up is to
disconnect the auto trim when the manual trim is actuated. Now the
questions: (If the relay I am using has 1 and 2 as NC, 3 and 4 NO, 5 and 6
as the commons, and 7 and 8 the coils). What is the purpose of the bridge
rectifier? When the relay is in the NC position is the manual trim over ride
on or is the trio auto trim on? What wiring diagram would represent this set
up better than the attached diagram? HELP.......LOST in a wiring maze again.
I know......I know sweet just to all my poor chemistry student that I
couln't see why they copuldn't understand quantum mechanics!
TIA

Interesting; I've never seen a relay with a polarity preference for
the K-coil, but this circuit seems designed to feed electrons into
only one end of the coil regardless of manual trim voltage polarity to
the motor. I thought magnets was magnets 
Bob, what's up here?

Well, the design does supply suppression diodes across the coil no matter
what the input polarity. Not certain that was Trio's intention.
