Stop) switches located at key points around the machine.
The E-Stop switches are to be used when the machine is out of control or is
about to damage personnel or equipment.

machine. The motors will stop but power to the PLC and the Operator Sta-
tion Screen will remain on.
Note:
The machine responds in the same way if you press the STOP button on the
operator's station.

stop is resolved:
