GAUGES

Generator Parameters and, for PM-PC, Bus/Utility Parameters have
an option to view the data using dial gauges. These are accessed
through the parameter screens by pressing the "Gauges" button.
The dials are separated into three different views: voltage, current,
and power. When viewing one category, the other two categories
can be selected by buttons at the bottom of the screen. Voltage
displays the volts of all three phases, with an option to select
"delta" or "wye" configuration. Current displays the current for all
three phases. Power displays the kW, power factor, and frequency.
The current and power categories also have an option to set the
gauge scale. The maximum rated current, maximum rated power,
and target frequency will be entered here during initial set up. The
PM-PC has different settings for both the generator and the bus.
These settings will be retained if power to the screen is lost.

GRAPHS

Selecting "Graphs" from the main menu will bring up a screen with
options for selecting which parameters to graph. Pressing these
buttons will cause them to turn the color of the corresponding line
on the graph. If a button is still grey, its data will not be shown on
the graph. Instead, it will read zero at every time interval. The time
interval can be changed by pressing the up and down arrows, or
by pressing directly on the number field to enter a value via the pop
up keyboard. A range from 0.1 to 10.0 seconds is available. To
view a graph of the selected parameters, press "Graph". Press and
hold on the graph to stop it and display the values at this time
interval. The graph will continue to update while it is stopped in this
way, and letting go will cause the graph to jump to the most recent
measurements. Navigating away from the graph screen will pre-
vent the graph from updating with real-time values. Pressing the
"Clear" button will turn off all of the selected parameters and reset
the time interval to 1.0 second.
Power and Current are shown as a percent of the maximum rated
value.
Use the "Set Graph Scale" option to ensure the power and current
are displayed correctly. The maximum rated power and maximum
rated current of the generator will be entered here during initial set
up. These settings will be retained if power to the screen is lost.
