I wanna design a Start-Stop circuit which onctrols 3 motor starters. If I connect all three motor starters so that if an OVERLOAD occurs on any one of the starters. all three starters will automatically diusconnect. More than one overload is needed since there are more than one motor starter. Physically, the overloads aren't part of the PLC because if the PLC stops then the emergency stop wpould be of no use, from my understanding. Physcially, it must be separate from the PLC, like an emergency stop button. My question is where does it connect to though, and how will it make the 3 motor starters stop automatically when an overload occurs. Thanks in advance.
