Emergency Shutdown and Recovery
Depending on the model of machine, there are emergency shutdown (E-
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.
When an E-Stop switch is activated, high voltage power is cut to the
