My start stop button blinking.. not the green clean one know I how to do that one also lock button is red. Tried unplugging and restarting to no avail..

If this for the sawmill, your dishwasher... or your bulldozer?

It sounds like a stop-start-jog switch like we had to wire up in technical school. I hated figuring out how to wire one up when all you have are three momentary buttons (single-pole/double-throw) and a contactor. The jog switch is the one that is the hardest because it has to make and break a circuit. Try figuring it out-good puzzle.
