operator that a diagnostic exists.The second purpose is to
provide navigation to a diagnostic display screen.
Note: A complete listing of diagnostics and codes is
included in the Diagnostic Section.
Manual Override Exists
An indicator to present the presence of a manual override
will share space with the Alarms enunciator key. While a
manual override exists, the space used for the Alarms key
will be occupied by a“Manual” icon, that will display solid
inverse color similar to the appearance of the Alarms
enunciator. An Alarm will take precedence of the Manual,
until the reset of active alarms, at which point the Manual
indicator would re-appear if such an override exists.
If the Manual indicator is pressed, the Manual Control
Settings screen will be displayed.
Main Screen
The Main screen is a “dashboard” of the chiller. High level
status information is presented so that a user can quickly
understand the mode of operation of the chiller.
The Chiller Operating Mode will present a top level
indication of the chiller mode (i.e. Auto, Running, Inhibit,
Run Inhibit, etc.).The “additional info” icon will present a
subscreen that lists in further detail the subsystem modes.
The Main screen shall be the default screen. After an idle
time of 30 minutes the CH530 shall display the Main screen
with the first data fields.
The remaining items (listed in the following table) will be
viewed by selecting the up/down arrow icons.
Chiller Operating Mode
The machine-operating mode indicates the operational
status of the chiller. A subscreen with additional mode
summary information will be provided by selection of an
additional information icon (>>).The operating mode line
will remain stationary while the remaining status items
scroll with the up/down arrow keys.
