OK, I can see the light at the end of the tunnel on this panel remodel and I've hit a brick wall; I hope someone here can help! The airplane has MAC servos for both roll and pitch trim, and electric flaps. For indication it has the little multi-element LED indicators for all three functions. As these have proven to be unreliable in this airplane, and the GRT Horizon display has analog inputs for these functions, I'm planning on trashing the LED indicators in favor of the GRT display. That's the plan - and that's about as far as I can go. I don't understand the feedback mechanism (How does the indicator "know" what position the surface is in?) Does this little device have something to do with it?
Here's another , for the flaps:
There appears to be very little info about these things on the Web, and all searches keep turning back to the Ray Allen page. Are these the same products?
Part 2 of the question concerns the interface with the GRT displays. The manual explains that the analog inputs are available to support a 0-12 volt input signal, but that's about as much detail as it covers. Does information exist (like a schematic) that shows the wiring interface for the position indicators? Does the display function have to be "enabled" after the signal lines are hard wired?
Thanks much!
