Awesome - thanks.
OK, so maybe I should have an interlock. I never thought it was a problem, but if there's a law...
Some (most?) controllers also have a built in "high pedal interlock", which uses internal logic to prevent the controller from working if the pot input is not "idle" when the Key Switch Input is switched on. But not this one.
So essentially
everything gets fused? Should I put a fuse inline with the potbox microswitch too?
Here's another question: someone asked why I was using pack voltage to control the main contactors. Do you happen to know if they'll work on 12v? Or will they just pull more current and get hotter?
