4.14 Configuration Screen
The Configuration Screen is a password protected screen, used only at initial start up to set the
horsepower. If a new version of the display program is installed you must press the reset hp
button on the Setup Screen to update the displays.
4.15 Maintenance Screen
The Maintenance Screen is used to facilitate maintenance procedures and provides the PLC and
display logic part number and revision number. When started from the Maintenance Screen, the
machine starts in recirculation mode.
In recirculation mode the 4-way valve will shift to one side or the other, improving
cooling efficiency. When the valve shifts it is possible for a small amount of high
pressure water, 20,000 psi (1,379 bar), to be created. For this reason, it is
suggested that the cutting orifice remain open during recirculation mode.
