Re: New to me Tree Journeyman 425
Looks like a fun project. One that I have done a few times.
I would start by tracing wires from the field devices: Limit switches, prox sensors, pumps, ect. Write it all down, device, function, wire color, wire number, cable identifier, and connection points on both ends. Now you have an I/O map to work from. Then you can strip out all of the hardware that will not be used, but I would keep all of the heavy power handling components in place if they can be reused.
Then create a new I/O map with all of the connections to the new hardware. Makes wiring it up pretty easy.
I'll be watching your progress
