Figure 55: Trend History Screen
The Trend History Screen allows the user to view the
various parameters listed on the right side of the screen. The
temperature scale in °F is on the left. Pressure in psi and %
RLA are represented by the right-hand scale. The COMP
button toggles between compressor #1 and compressor #2.
Notice that three separate red lines are displayed on the Trend
History Screen. Two of those red lines will be thinner than
the other. The thin red line on the bottom of all the red lines
represents the minimum motor speed. The thin red line on the
top of all the red lines represents the maximum motor speed.
The thick red line, which should be somewhere between the
minimum and maximum motor speed lines, represents the
actual motor speed.
The Trend History Screen can display history for 24-hour,
4-hour, 1-hour, or 15-minute periods by pressing 24, 4, 1, or
1/4, respectively. Pressing the NOW button for any time period
will start the display for the current time beginning on the right
of the screen with history flowing to the left. The arrow buttons
scroll the time period forward or backward.
When the HMI PC is powered on after being off, the Trend
History Screen will only display the history starting from the
time the HMI PC was powered on. Previous trend history
can be downloaded but there will be a gap in the data from
when the HMI PC was off. Trend history is not affected if only
the HMI screen (not the HMI PC) is off or in sleep mode. For
details on how to download the trend history, reference the
