8. If the engine does not start after the first cranking attempt, the engine will pause for 15 seconds to allow the
starter to cool. The LCD window will show “PAUSE”. The engine will make two more attempts to start for a total
of three crank cycles.
9. Should the engine not start and run within three starting cycles, the LCD window will show “SD Start fail”. The
starting sequence may be repeated after the starter has had a minimum of two minutes to cool. Press the “FAULT
RESET” button to clear the controller. To start the unit, press the green “ENGINE START” button.
Note: The engine controller may skip the preheat engine steps on some of the larger models.
10. 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 LCD window will show engine and generator operating parameters. Temperature will be shown as “0”
until the engine temperature is approximately 100°F (38°C).
11. Check the generator for excessive noise or vibration and any coolant, oil or fuel leaks before applying any loads.
12. Check that the AC output voltage is correct. The output voltage can be fine adjusted by using the fine voltage
adjustment screw (rheostat). Refer to “Fine Voltage Adjustment ” on page 19.
13. Check that the frequency (Hz) is correct. With no loads connected to the generator, the frequency should read
approximately 60 Hz, depending on the type of engine governing used.
14. If all wiring connections have been attached and secured correctly, switch the main circuit breaker to the “ON/I”
position and then add any loads attached to the convenience outlets 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 GENERATOR
The “AUTO” button is used when the generator is started from a location other than the control panel and 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 generator in the “AUTO” mode, review the Pre-Start Check List and Manual Starting of the
Generator. Refer to “Pre-Start Check List” on page 20 and “Manual Starting Of The Generator” on page 20. 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 “Transfer Switch” on page 34. Then continue with the steps described below:
1. Perform a manual start of the generator at least once to verify 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” button, the Liquid Crystal Display (LCD) window should highlight “AUT” in the upper
left corner. Attach a jumper wire (minimum 16 gauge) across the two terminals on the remote start terminal
block. This applies a ground to the Magnum Digital Controller (MDC) 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 unit is in “AUTO” mode. The LCD window should have “AUT” highlighted in the upper left corner.
5. Close the main circuit breaker (set to “ON/I”).
6. Secure the generator by closing and locking all access doors.
7. The generator is now ready for remote starting. Refer to “Remote Start Terminal Block” on page 33.
