The trends will be shown for the Duration value,
ending at the current time. When ‘Now’ is checked,
the system defaults to the current date and time.
If ‘Now’ has been checked, ‘Duration’ is the only
editable field.
For viewing historical data, uncheck ‘Now’.
Enter the start date and time, along with duration to
view data for desired time. Tap [Apply] to apply
changes or [Close] to cancel any changes.
NOTE: If ‘Now’ is left unchecked, the system does
not default back to the current date and time.

The trends graph may be enlarged for a better view

Configuring the Data Shown on the Screen
In technician mode, you can change the data the
screen shows. Click on “Configure Data”.
Figure 9: Configure Data
Check the box next to the data you want to show.
Not all data is available for all systems. Use the
slider bar on the right to adjust the graph scaling to
a value that makes it most comfortable to read.
100% means the graph scale is the same as the
analog scaling max value. 110% means the graph
scaling is 110% of the analog max scaling for the
channel. The exception here is the KW reading,
which is an absolute number because KW is read
directly, rather than scaled.
Click “Channels” to access the calibration screen
directly from the “Configure Data” screen.
This screen is accessible also from “Setup”-
>”Options Setup” and is discussed in detail in that
section.
Click “Technical Overview” to access details of
system operation. This is also accessible from the
“Green Flag” button on the header of other screens.
Figure 10: Technical Overview
This screen shows an overview of the configuration
of the station. Most data that is necessary for
tuning is shown, and the settings page for the
information can be accessed by touching the value.
For technicians, the fields available on this screen
should be fairly self-explanatory. However, some
fields can use some clarification:
Figure 11: Combo Information
This field shows, from left to right, the current
combo (highlighted), start time, psi below setpoint,
stop time and psi above setpoint to stop, for each
combo. To the right is a table detailing the pumps
to run in each combo. The example above shows
combo 1 consists of the PM Pump, Combo 2
consists of pump 1 (or any other single pump in the
same group), combo 3 is two main pumps, and
combo 3 is 3 main pumps.
