4.2. EMERGENCY-stop push button
There is an EMERGENCY-Stop push button (see chapter 4.1 No. 9) on the CNC control unit, for
interrupting the working process if the work piece, tools or persons are endangered by the
working pressure.
The devices connected to the plug boxes (e.g. heating element and planer ) are
not disconnected from the main power by the EMERGENCY-Stop and for this
reason dangers due to these devices are still possible.
Turn the main switch off or unplug the main connector!
•
The EMERGENCY-Stop push button snaps when it is operated.
•
In case the EMERGENCY-Stop push button was pushed, the system is pressure-less and the
sledge can only be moved manually.
•
After elimination of the danger, the EMERGENCY-Stop push button must be unlocked again
by turning it in clockwise direction and the functions of buttons <+> and <-> (open and close
the sledge) are possible again.
4.3. Separating device for heating element
There is a tear-off bar mounted between the
movable and the fixed clamping shells on the
basic machine. It prevents the heating element
from sticking to the heated-up pipe ends.
When inserting the heating element take care
that it lies in the zone of the throat of the tear-
off bar (see arrow).
