    Hello Guys, I came across this Contactor control diagram today and had difficulty in understanding it right away. Can any one tell me how this control circuit works?

    Could you be more specific about which part of the drawing you are having the most trouble with?

    So I cannot understand how KX coil will close, which intern close the main contact. The way I understand, KX coil will be energized when contact M or contact UV is closed, when PB-E1 is pushed with SSW in local. I might be understanding wrong way.
