OK, I think that relay will latch when you hit the reset, then stay on until you hit the e-stop. This will tell the BOB to stop.
BUT ! - it looks like you are switching the mains live feed through the same 12V relay ? Don't do this. You need a contactor in-between. This is like a relay but can handle mains voltage and has purposed built contacts. It is controlled by a low voltage signal - i.e. one coming out of the safety relay.
Either revert back to your first design, or get familiar and be happy with contactors and mains control.
