9.0 OPERATING INSTRUCTIONS
DISPLAY SCREEN
The display screen is divided into three functional areas,
as seen in the typical CURRENT STATUS screen shown
here.
The left side continuously shows the package discharge
pressure in large numbers showing the running condition
of the machine and the line below that showing the
present mode of operation.
The right side shows various items or lists such as the
machine’s CURRENT STATUS readings, the MAIN MENU,
the OPERATOR SETPOINTS list, etc. Any of the lists can be
moved up or down by pressing the arrow buttons to the
right of the screen. The small arrow(s) displayed in the
upper right corner of the screen indicate when you can
move up and/or down through a list. The arrow buttons
are also used to change an individual item’s value. At
certain times, items and/or their values are “highlighted”.
This means that they are displayed as light characters on
a dark background.
The bottom of the screen is divided into thirds with the
words in each small box showing the function of the
button directly beneath it. The words will change in these
boxes depending on what actions are permitted at any
particular time. The action resulting from pressing each
of these buttons is indicated in the Operator Panel Flow
Diagram later in this section. This can be used as a quick
reference of how to step the controller screen through
any desired function.
CURRENT STATUS
The CURRENT STATUS screen is considered to be the
“normal” display that the controller shows.
The following items and their present values can be
displayed on the right side of the screen by pressing the
up and down arrow buttons.
