I just started reading about ladder diagrams. Couple of things I don't understand about the Stop/Start/Starter overloads/Motor starter ladder rung.
Do all of the conditions have to be true along the rung of the ladder for the output to be set? Anded?
I understand why a stop is a normally closed switch for safety but why is it a normally open on ladder diagram?
Stop is a closed switch and the Start is a open switch but both are normally open on the ladder diagram.
