The position of the needle on the gauge indicates the current pressure reading as displayed in the
digital value in the center of the gauge. The yellow region on the right of the gauge begins at the
current setting for the
Unload Pressure
and the red region on the right of the gauge begins at the
Pressure Fault
setting. The scale of the gauge and location of the yellow and red zones will change
dynamically according to the configuration of the system.
The
Discharge Temperature
and
Reservoir Pressure
gauges are formatted in a very similar fashion
to the
Plant Delivery Pressure
gauge, with yellow and red zones configured as noted in Table 2-3.

From each gauge screen, pressing the button next to the
Home
icon will navigate back to the home
screen. Pressing the button next to the
Trend
button will navigate to the trend history of this sensor
reading recorded over time as described in section 2.3.2.2.
2.3.2.2 Trend Graphs
The readings from the primary sensors on the system are logged at a fixed interval during
compressor operation and may be displayed on the screen by navigating to the
Trend
screen from
the respective gauge. An image of the
Discharge Temperature Trend
screen is shown in Figure 2-5.
Figure 2-5: Discharge Temperature Trend
Trend data files are loaded one date at a time. The x-axis across the bottom of the screen indicates
the hours in the day based on the current date and time setting of the controller. The current date
loaded is shown in the bar at the bottom of the screen, and the data scale is indicated on the y-axis.
Pressing the right arrow
will load the next day in the log history, the left arrow
will load the
previous day in the history. If a log is requested for a date when the compressor was not powered,
either in the past or in the future, a message will be displayed indicating that no log is available.
Pressing the double left arrow will navigate back to the respective gauge screen regardless of
what date has been loaded.
