Air-Fuel-FGR
This area of the display shows the current positions of the
actuators as a percentage of their closed-to-open range, from
“00%” to “100%”.
A--%—shows the air actuator position.
F--%—shows the position of the currently selected fuel
actuator.
R--% or H--%—shows the position of the FGR actuator. If the
system does not included an FGR actuator, then this item is
blank. The “H” indicates that an FGR hold (an option enabled
during commissioning) is currently active because the R7999
XmA input is (or has been) below the Enforce threshold and
has not yet crossed the Release threshold, whereas “R”
indicates normal, no-hold FGR operation.
Pushbuttons
The two lefthand (SCROLL) pushbuttons scroll the second
line up and down through a list of menu items.
The third pushbutton (
) provides a toggle function.
The fourth pushbutton (
) provides a change level
function.
In the top-level menu, an item that provides access to a
submenu is indicated by a right-pointing arrowhead ( )
following the submenu description (Inputs/Outputs, Motor
Settings, Configuration Settings, Fault History and Line 2
Legend). Pressing the change level button when a submenu
description is displayed will shown the first item of submenu
information and will cause an identifier for the submenu to
appear in the LINE2 area in the top right corner of the display.
Each submenu item has a left-pointing arrowhead (
) to
indicate that the change level pushbutton may be used to exit
the submenu and return to the top-level menu. In the top-level
menu, the LINE2 area is blank.
The toggle button cycles the second line of the display
between the main display and whichever second line was
most recently shown by using the scroll and change level
pushbuttons. This provides a way to quickly return to the main
display. The toggle button may also be used to compare the
main display to some other item by quickly toggling between
them.
NOTE:
If the display has just been powered up, or if the
scroll buttons have been used to return to the main
display, then there is no other second line as
described above for the toggle pushbutton. In this
case the Run Time item from the top-level menu is
used.
The top-level menu and each of the submenus wrap around,
that is, scrolling down beyond the last item causes the first
item to appear; and scrolling up beyond the first item causes
the last item to appear.
The pushbuttons are disabled while the display is starting up.
An up/down arrow indicator appears in the lower left corner of
the display after initialization is complete and the buttons are
enabled.
All of the selectable second line messages are shown in
Table 3. Submenu items are shown indented under their
top-level menu description.
