6. Should the engine not start and run within three starting cycles, the LCD window will show the “Fail to Start”

alarm. The starting sequence may be repeated after the starter has had a minimum of two minutes to cool.

Pressing the Enter () button will clear the alarm and reset the controller.

Note: The engine controller may skip the preheat engine steps on some of the larger models.

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 38.

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.

AUTO (REMOTE) STARTING OF THE UNIT

Auto Mode is used when the unit is started from a location other than the control panel by using a transfer switch.

Auto (remote start) is the normal setting when the generator is being used as a standby power supply. Before putting

the unit in the Auto mode, review the “Prestart Checklist” on page 31 and “Manual Starting of the Unit” on page 32.

Also follow all safety warnings and information on isolating the generator with a transfer switch if the unit is to be

used as a standby power supply. Refer to “Prestart Checklist” on page 31. Then continue with the steps described

below:

1. Perform a manual start of the unit at least once to verify that the engine is operating correctly.

2. If a check of the remote start circuit is desired, remove the wires from the remote start terminal block.

Press the Auto/Manual Mode ( ) button, the LCD window should show “Auto Mode” at the top of the

screen. Attach a jumper wire (minimum 16 gauge) across the two terminals on the remote start terminal

block. This applies a ground to the Power Zone™ Controller to close the starting circuit contacts. The

engine should crank, start and run.

3. Remove the jumper wire from the remote start terminal block and the engine will stop. Reconnect any

necessary wires from the remote start switch (transfer switch) to the remote start terminal block.

4. Confirm the unit is in Auto mode. The LCD window should show “Auto Mode” at the top of the screen.

5. Close the main circuit breaker (set to the ON (I) position).

6. Secure the unit by closing and locking all access doors.

7. The unit is now ready for remote starting.

VOLTAGE REGULATION

The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field.

The regulator has six screwdriver adjustable potentiometers that may be adjusted for U/F dip, under frequency

protention (U/F), droop, stability, voltage, and trim. The voltage regulator on the unit is adjusted before shipment

from the factory. Contact Magnum Power Products LLC for additional information before attempting to adjust the

voltage regulator.

Note: For units equipped with a Marathon DVR2000E+ digital voltage regulator, please refer to the Marathon operating

manual provided with the unit.
