5. AUXILIARY LIGHT SWITCHES: These switches operate optional control panel and interior lights. 6. AIR FILTER METER: This gauge shows the condition of the air filter when the engine is running. 7. MAGNUM DIGITAL CONTROLLER (MDC): Refer to “Magnum Digital Controller (MDC)” on page 8.
MAGNUM DIGITAL CONTROLLER (MDC) The MDC is an enhanced digital generator controller used to start, stop and monitor the operation of the generator and the engine. The controller constantly monitors vital generator and engine functions for a number of pre- programmed alarm and fault conditions.
• “MANUAL ” button: Press this button to change from the automatic (remote) starting mode to manual starting mode. • “AUTO ” button: Press this button to change from manual starting mode to automatic (remote) starting mode. • “ALARM CANCEL” button: When an alarm is activated, either visually or audibly, press this button to silence or cancel the alarm.
ENGINE MONITORING Engine information is shown on the Liquid Crystal Display (LCD) window in a toggling manner with the generator information after the first 60 seconds of operation and then every five seconds thereafter. The Engine Display screen will show oil pressure, engine coolant temperature, fuel level and battery voltage. •...
FINE VOLTAGE ADJUSTMENT Upon startup of the generator, the “Running” screen of the Magnum Digital Voltage Controller (MDC) will display “V Detect” and will countdown from 45 seconds to...
This screw turns a rheostat that will provide an increase (“+”) or a decrease (“-”) in the generator output voltage as displayed on the generator display screen on the MDC. If the voltage is increased or decreased too fast or too slow, the unit will automatically shut down.
MANUAL STARTING OF THE GENERATOR 1. Move the “CONTROL ON/OFF” toggle switch to the “CONTROL ON/I” position. DANGER CARBON MONOXIDE: USING A GENERATOR INDOORS CAN KILL YOU IN MINUTES! 2. The Liquid Crystal Display (LCD) window will quickly display system information, all Light Emitting Diodes (LED’s) will flash.
6. The “Running” screen will display. Note: It may take a few seconds for the engine to run smoothly and reach its governed operating speed. The 45 second “V detect” time delay will start to countdown. 7. The LCD window will then toggle from the “Running” screen to the generator display screen and then to the engine display screen.
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.
Shutdown (SD) outputs GCB CLOSE/OPEN, FUEL, SOLENOID, STARTER and PRESTART to stop the engine immediately. MAGNUM DIGITAL CONTROLLER (MDC) - LIST OF ALARMS Shutdown and warning fault conditions and the displayed message are described in the following table: Information on...

*Note: The Suspect Parameter Number (SPN) is displayed as “FC” on the bottom left of the LCD window. See Figure 1. MAGNUM DIGITAL CONTROLLER (MDC) - HISTORY The MDC stores a record of each important event in the history file of the controller. The history file seats 117 records.
IL-NT analog input 2 value (default: water temperature) ADJUSTING THE DISPLAY BACKLIGHTING The brightness on the Liquid Crystal Display (LCD) window may be adjusted by the operator whenever the Magnum Digital Controller (MDC) is powered up. Note: Anytime an “*” is displayed on the LCD window, the text or set point cannot be changed without the use of a password.

2. Check for leaks in the fuel tank. The fuel tank should not run dry under normal circumstances. The engine controller will shut the engine down when there is 5% of fuel remaining in the tank. This is done to keep the fuel lines from running dry.
GENERATOR OUTPUT CONNECTION LUGS The generator is equipped with connection lugs, located behind the lug box door next to the customer convenience receptacles. The lugs provide connection points for attachment of external loads to the generator. A large decal on the inside of the connection lug door details the proper connections for selected voltages.

The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage roll-off (U/F). 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.
When the generator is used as a standby power supply, it must be equipped with a transfer switch which isolates it from the utility’s distribution system. A transfer switch is designed to transfer electrical loads from the normal power source (utility) to the emergency power source (generator) when normal voltage falls below a prescribed level. The transfer switch automatically returns the load back to the normal source when power is restored back to operating levels.
4. Choose the day or days the unit should run and press “ENTER.” 5. Press the down arrow “” button until “Timer1 ON Time” is selected and press “ENTER.” 6. Adjust the desired time to start running and press “ENTER.” 7.
• If the unit is stored outside, check for water inside the cabinet and generator before each use. If wet, dry the unit thoroughly before starting. BASIC MAINTENANCE SCHEDULE - JOHN DEERE ENGINE Refer to the original equipment manufacturer’s operating manual for a complete list of maintenance requirements.
BELT TENSIONERS John Deere engines use two types of belt tensioners: manual and automatic. Adjust the belt using the manual tensioner according to the manufacturer’s specifications. The automatic tensioner cannot be adjusted or repaired and is designed to maintain proper tension over the belt’s life. Units with the automatic belt tensioner must be inspected according to the manufacturer’s specifications.
2. Remove the generator fan guard. 3. Torque each of the drive plate bolts to the appropriate specification in the table below. Unit ft-lbs (Nm) MMG75CAN6 36 (49) MMG100CAN6 36 (49) 4. Reinstall the generator fan guard. Reconnect the battery.
AUXILIARY FUEL TANK OPTION The auxiliary fuel tank option is designed so the unit can run from an external fuel tank. The unit is still programmed to shut down when the internal tank’s fuel level drops below 5%. In order for the unit to run off of an auxiliary tank, the fuel level in the internal tank must remain over 5%.
