3.1.2 FUNCTION / DATA KEYPAD LAYOUT AND PROTOCOL
The PPC3 has a function/data keypad for local operator access to direct functions, function
menus and for data entry.
1. The Function/Data keys allow very commonly
used functions to be accessed directly by a
single keystroke when pressed from the
MAIN RUN screen (see Section 3.2.7). The
name of the function is on the bottom half of
the key. These keys enter numerical values
when editing.
2. The Editing and Execution keys are for
starting and suspending command execution,
cursor control in menus and editing entries.
3. The Menu/Data keys provide access to
function menus when pressed from the
MAIN RUN screen. The menu name is on
the bottom half of the key. The SETUP menu
is for more frequently used functions (see
Section 3.4). The SPECIAL menu is for
functions that are not generally used as a
part of day to day operation (see Section
3.5). These keys enter numerical values
when editing.
Figure 4. Keypad Layout
Pressing the [ENT/SET P] key generally causes execution or forward movement in the menu
tree. Pressing [ENT/SET P] from the MAIN RUN screen allows an automated pressure
control command to be given.
Pressing the [ESC] key moves back in the menu tree and/or causes execution to cease or
suspend. Pressing [ESC] repeatedly eventually returns to the MAIN RUN screen and, from
there, allows momentary viewing of the PPC3 introduction screen.
Pressing the [+/-] key changes a numerical sign when editing. It also toggles through
multiple screens when available and is a shortcut to a momentary display of the active
RANGE from the MAIN RUN screen.
Pressing the [
], [ ], [ ] and [ ] keys allows reverse, forward and up, down cursor
movement when editing data entry or moving in menus.
Some screens go beyond the two lines provided by the display. This is indicated by a
flashing down arrow in the second line of the display. Press the cursor control keys to
move the cursor to access the lines that are not visible or directly enter the number of
the hidden menu choice if you know it.
