Have a question that has my entire class stumped ;
We have two motor/motor starters, with plenty of aux's (Both normally opened and normally closed), and control relays.
We have to wire a single push button start/stop to do the following ;
On the first start press, Motor A turns on. When you hit stop, it stops.
On the second start press, Motor B turns on. When you hit stop, it stops.
On the third start press, Motors A and B both turn on. When you hit stop, both stops.
After that, it has to repeat.
We're all drawing a blank and I've been pondering it all day, and I have about 60 sketches of "****, that's not rights". Any help?
