Good code references Ernie, I think we are back to some form of interlocks with pneumatic timers that will allow a person to start a single motor and keep it running until the timer runs out or until the second motor is running. As it is described, if both motors are off, and they are on separate starting circuits, you would not be able to start either one because the alternate motor interlock would not allow it to start. Yep, pneumatic timers would work. The PLC thing would/could work but I know they want to break the neutral improperly.
