SHUTTING DOWN
Check with personnel using power supplied by the generator and let them know the power is going to be turned off.
Make sure the power shut down will not create any hazards by accidentally turning off equipment that needs to be
kept on (pumps, compressors, lights, etc.).
1. Remove all loads from the generator by opening all circuit breakers (turn to “OFFO”).
2. Let the engine run for approximately five minutes to allow it to cool down.
3. Push the red “ENGINE STOP” button. Pressing “ENGINE STOP” will result in the generator going into
the shut down cycle and starting a 15 second shut down timer called “Stop Value.” If the unit does not
shut down within 15 seconds, a “Stop Fail” alarm will be displayed on the Liquid Crystal Display (LCD)
window.
4. Move the “CONTROL ON/OFF” toggle switch to the “CONTROL OFF/O” position.
Note: For extended storage time, disconnect the battery. Refer to the operator’s manual for extended storage
requirements.
MDC CONTROLLER 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 shutdown. To resume operation, the fault
condition must be resolved. To reset the controller and resume operation, press the “FAULT RESET” button.
The operation of the Magnum Digital Controller (MDC) is divided into the following sections:
