Freq: Displays the output frequency in Hertz (Hz). Normal operating frequency is 60 Hz.
Volts: Displays the nominal voltage in Volts (V).
Amps: Displays the AC output amperage produced by the generator in Amps (A).
Additional information can be found on the electric power table at the bottom-left side of the screen. This provides
an overview of all three lines and average voltage and amperage readouts.
VOLTAGE ADJUST SCREEN
The Voltage Adjust screen displays the line-to-neutral and line-to-line voltage averages. The operator can electron-
ically adjust the voltage within limits to prevent under-voltage or over-voltage conditions using the on-screen
instructions. This feature replaces a traditional potentiometer. Refer to “Fine Voltage Adjustment” on page 38 for
more information.
MAINTENANCE SCREENS
All of the data inputs from the engine, generator, inputs/outputs, schedule and Power Zone™ controller are visible
