3. Press the "
" (Enter) key.
If the value is within range, it is accepted and the
dialog box disappears. The chiller will begin to op-
erate based on the new programmed value. If out of
range, the value will not be accepted and the user is
prompted to try again.
Manual Controls
Some keys are used to perform manual control func-
tions. These may involve manual control of items such
as the control valves, solenoid valves, and other keys in
this category are used to initiate/terminate processes
such as calibrations or reports.
Free Cursor
On screens containing many setpoints, a specific “soft”
key may not be assigned to each setpoint value. A soft
key will be assigned to enable the cursor arrow keys
below the numeric keypad which are used to “highlight”
the desired setpoint field. At this point, the "
" key is
pressed to bring up a dialog prompting the user to enter a
new setpoint value. The "X" key cancels cursor mode.
NAVIGATION
In order to maximize the amount of values which the
panel can display to the user, and in order to place those
values in context, multiple screens have been designed to
describe the chiller operation. In order to move from one
screen to the next, navigation keys have been defined.
These keys allow the user to either move “forward” to
a sub-screen of the present screen, or move “backward”
to the previous screen. Except for the Home Screen
display, the upper-right “soft” key will always return
the user to the Home Screen. Navigating with “soft”
keys is as simple as pressing the key next to the label
containing the name of the desired screen. The system
will immediately refresh the display with the graphics
for that screen.
LANGUAGES
The Screens can be displayed in various languages.
Language selection is done on the CONFIGURE Screen.
The desired language is selected from those available.
Not all languages are available. English is the default
language. If a language other than English is being dis-
played, an English-only speaking person should navigate
to the CONFIGURE Screen using the preceding Navi-
gation chart and select English per the CONFIGURE
Screen instructions in this book.
