MAIN CONTROL PANEL COMPONENTS 1. MAIN CIRCUIT BREAKER (90A): This breaker will disconnect power to the connection lugs. 2. LUG DOOR SAFETY SWITCHES: These switches will shut the generator down if the lug door is opened when the generator is running. 3.
MAGNUM DIGITAL CONTROLLER (MDC) The Magnum Digital Controller (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. When a fault condition occurs, the engine will shut down automatically and the Liquid Crystal Display (LCD) window will display the fault that caused the shutdown;...
• “ALARM CANCEL” Button When an alarm is activated, either visually or audibly, press this button to silence or cancel the alarm. • “FAULT RESET” Button Press this button to clear the fault from the LCD window after the fault has been corrected. Press “FAULT RESET”...
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 5 seconds thereafter. The engine display screen will show oil pressure, engine coolant temperature, fuel level and battery voltage. •...
These codes will not be lost when the control power toggle switch is powered off. FINE VOLTAGE ADJUSTMENT Upon start-up of the generator, the “Running” screen of the Magnum Digital VOLTAGE CONTROL Controller (MDC) will display “SENSING” and will countdown from 45 seconds ADJUSTMENT to “0”...
MAGNUM DIGITAL CONTROLLER (MDC) INFORMATION DISPLAYS, FUNCTIONS AND RESET The Magnum Digital Controller (MDC) constantly monitors vital generator and engine functions for a number of operation, alarm and fault conditions. When a fault condition occurs, the engine will shut down automatically and the Liquid Crystal Display (LCD) window will show the fault that has caused the shut down.

MAGNUM DIGITAL CONTROLLER (MDC) – HISTORY The Magnum Digital Controller (MDC) controller stores a record of each important event into the history file of the controller. The history file seats 118 records. When the history file is full, the oldest records are removed.
RESETTING OF THE “TIME TO SERVICE” REMINDER The Magnum Digital Controller (MDC) will display the message “ WrnServiceTime” when the unit is due for mainte- nance or service. The maintenance or service interval is set at 250 hours of engine running time. Once the unit has been serviced, the “ServiceTime”...
GENERATOR OUTPUT CONNECTION LUGS The generator is equipped with connection lugs behind a door below the controller face. 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.
VOLTAGE SELECTOR SWITCH The voltage selector switch is located behind the lug door, underneath the engine controller panel. The selector switch is a three position switch that mechanically changes the connections between the generator output leads and the connection lugs. Voltage ranges are selected by rotating the handle on the switch to the desired voltage. NOTICE Never change the voltage selector switch while the engine is running! This will cause sever arcing and damage to the switch and generator windings.
The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and under frequency (U/F). The voltage regulator on your unit is adjusted before shipment from the factory. Contact Magnum Products LLC for additional information before attempting to adjust the voltage regulator.
MAIN CIRCUIT BREAKER The main circuit breaker is located on the main control panel. When the breaker is in the OFF “O” position, power is interrupted between the customer connection lugs and the generator. Once the connections have been made to the connection lugs and the generator has been started and allowed to reach normal operating temperature, the breaker may be switched to the ON “I”...
Installation of a transfer switch or other type of remote starting device is the responsibility of the generator user. Installation of such devices must be performed by following all directions supplied by the manufacturer of the switch. If attaching generator to a power supply normally serviced by a utility company, notify the utility company and check local and state regulations.
LIGHT TOWER SET-UP 1. For maximum light coverage locate tower at ground level or in a spot higher than the area being illuminated by the lamps. WARNING Check for any overhead obstructions such as utility lines or vegetation as the tower extends up to 30 ft.
RAISING THE TOWER WARNING The trailer must be leveled with the outriggers extended before raising the tower. The outriggers must remain extended while the tower is up. Failure to level the trailer or extend the outriggers will severely reduce the stability of the unit and could allow the tower to tip and fall. 1.
RAISING THE TOWER WITH THE OPTIONAL ELECTRIC WINCH 1. Set up and level the trailer as described on page 25, and follow steps 1-3 on page 26. 2. Remove the safety pin from the mast lock bar (R). 3. Press the lower winch control toggle switch upward to raise mast into the vertical position (S).
LIGHT TOWER START UP Before starting the light tower, carefully read the pre-start check list. Make sure that all of the items are checked before trying to start the light tower. This check list applies for both manual and remote starting. PRE- START CHECK LIST Make sure the control ON/OFF toggle switch is in the OFF “O”...
Page 29
4. Press the green “ENGINE START” button. The Prestart (Preheat) screen will be displayed (if equipped) and a countdown will begin from 20 seconds to 0. 5. The Starting screen will be displayed. The engine will crank and start running. 6.
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.
LIGHT OPERATION 1. Once the engine is up to temperature and running smoothly, switch main circuit breaker to the ON “I” position. 2. With main circuit breaker on, switch each individual circuit breaker for the lights to ON “I”, one at a time. 3.
5. After the mast is completely down, insert the cradle lock pin and secure it with the safety pin. 6. If the trailer is going to be moved, Magnum Products LLC strongly recommends that the lights be removed from the mast and stowed for transportation. See REMOVING THE LIGHTS FOR TRANSPORTATION section on page 33.
REMOVING THE LIGHTS FOR TRANSPORTATION 1. On units equipped with quick disconnect fittings for the lights, disconnect the power cords from the junction box at the top of the mast. Replace the dust caps on the junction box. On other units, remove the junction box cover on the top of the mast and disconnect ONLY the mast light wires from the terminal blocks.
LIFTING THE TRAILER When lifting the light tower and trailer, attach any slings, chains or hooks directly to the central lifting eye. The lifting eye is located on the mast between the two forklift pockets. 1. Make sure the equipment being used to lift the light tower has sufficient capacity. Note: See the unit specifica- tions on pages 8 - 9 for approximate weights.
ENGINE MAINTENANCE Note: During the first 50 hours of operation, avoid long periods of no load or sustained maximum load operation. If the light tower is to run for longer than five minutes without a load, shut the engine down. The engine is supplied with engine break-in oil from the factory.
DERATING FOR ALTITUDE All light towers are subject to derating for altitude and temperature; this will reduce the available power for operating to tools and accessories connected to the auxiliary outlets. Typical reductions in performance are 2-4% for every 1000 ft. (305 meters) of elevation and 1% per 10º F (3-5º C) increase in ambient air temperature over 72º F (22.2º C). TROUBLESHOOTING SHUTDOWN CONDITIONS LOW OIL PRESSURE SHUTDOWN 1.
2. Generator output incorrect. Check the incoming voltage to the ballast by checking the available voltage on the duplex receptacle. Incoming voltage should be 120V +/- 5V. If voltage is incorrect engine speed may need to be adjusted or generator may require service. Contact Magnum Products Technical Service Department for more information.
