I have an old 60-ton press which I got cheap because it was damaged by a forklift while being moved. The electrical controls were completely destroyed. Basically, there is a 3-phase motor which when you turn it on, pumps more fluid. As long as you don't turn the release valve in the piping, the pressure will stay.
I'd thought I'd use an on/off/jog setup. Now I realize these need an auxiliary relay which is some complexity I don't necessarily want. I'm wondering if it would make sense to just wire a simple one-button setup. Push the button and hold it and the motor runs, let go and it stops. What do you guys think?
