This has been covered awhile back, but I'm stumped on a simple circuit and the installation manual hasn't helped (page 78 option 2). The Trio Propilot uses a double pole double throw relay to control the trim motor. One of the relays gets an input from manual hat switch on my infinity grip. The other relay gets the input of the auto trim on the Pro Pilot. There is a bridge rectifier to arbitrate the two input signals from the manual trim and the Propilot so there is only one control at any given time. In my case I am using the IDEC RH-2B cube type DPDT relay and the NTE 5322 bridge rectifier. The circuit drives the DC trim motor in forward and reverse.
pin 1 to Pin 5 on the trio servo pin 4 to pin 6 on the trio servo
pin 5 to hat switch UP - AC bridge pin 8 to hat switch down - AC bridge
pin 9 to trim motor pin 12 trim motor
pin 13 to ground and - bridge pin 14 to + 12 VDC and + bridge
the common on the infinity grip is connected to aircraft +12 VDC
Would someone please provide me guidance on where I've got this wrong?
