7. Once the engine starts, it will immediately begin speeding up to a constant 1800 rpm. The engine may hunt or

change speeds until operating speed is reached. After a few minutes of operation, the engine will be warmed

up and the Operator screens will show engine and generator operating parameters.

8. Check the generator for excessive noise or vibration and any coolant, oil, or fuel leaks before applying any loads.

9. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the Voltage Adjust

screen as described on page 18.

10. Check that the frequency (Hz) is correct on the Generator screen. With no loads connected to the generator,

the frequency should read approximately 60 Hz, depending on the type of engine governing used.

11. If all wiring connections have been made correctly, switch the main circuit breaker to the “ON/I” position and then

add any loads attached to the receptacles by switching the respective circuit breaker to the “ON/I” position. You

will notice a slight change in engine sound when a load is applied to the unit.

AUTOMATICALLY STARTING THE GENERATOR

The Power Zone™ controller is capable of starting and stopping the unit automatically, based on a programmable

schedule.

Generators installed in a standby application should be exercised regularly to maintain operating condition and to

ensure responsiveness in an emergency situation. Use the following procedures to operate the generator in “Auto

ously. The controller will display the Configuration Menu.

3. To save any changes and exit the Configuration Menu, press and hold the Enter “” button for five seconds. To

cancel any changes and return to the Maintenance screen, press and hold the Engine Stop/Reset “O” button for

five seconds.

SET THE CONTROLLER CLOCK

The schedule runs based off the time set in the controller clock. Use the following procedure to set the controller

clock BEFORE setting the schedule:

1. Navigate to the “Maintenance” group and access it by pressing the right arrow “►”.

2. Select the “Time” section by pressing the right arrow “►”.

3. Set the time and date to the correct local time.
