position ensuring that an uncontrolled
restart or new start of the machine cannot happen.

3. Interlocking: Only by releasing the
locking device manually (reset button on
the side of the housing), after the
dangerous situation has been cleared,
can the contacts be set to normal again.
The operating process can then be
repeated by operating the pedal to the
pressure point.
