The RFID Reader (for opening), and close/stop buttons at the bottom of the ramp have been wired back in. The longer range readers that we were going to install are AWOL, so the original controls were hooked up just to make it functional.
I got on the ladder and wired it, though it needs some terminal blocks installed at a later time for both reliability and ease of service (especially if a contractor or vendor works on the door, they won’t touch our wiring otherwise and it will get left out again).
Thanks to @StanSimmons for helping with the wire tracing to remap the buttons and a couple of people for helping me maneuver that giant A-Frame through the workshop.
Cheers,
