Generator Screen
The Generator screen displays the average voltage frequency, volts and amps from the generator, as well as line-
to-line voltage, and individual line-to-neutral voltage, amperage and power (kW). This screen also displays the
generator winding configuration set by the voltage selector switch in the lower right corner.
Figure 2-9. Generator Screen
Note: When loading the generator, it is important to observe the amperage to determine the load balance on each
line of the generator. Minor load unbalances, usually ten percent or less, will not cause problems. Every effort should
be made to distribute the load equally between all lines.
• 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 Shutting Down the Unit for more information.
