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 shut down; to resume

operation the fault condition must be resolved. The controller has the ability to provide the display readout in English

and Spanish; other languages are available. A screen print out of the display screen is also available. This controller

also records a “History” of the unit’s performance which may be viewed at any time and will not be removed or lost

when the controller is powered down.

The MDC panel consists of five sections, including: the “CONTROL ON/OFF” Toggle Switch and Fine Voltage

Adjustment Screw; the “OPERATION” keypad; the LCD window; the “DIAGNOSTICS” keypad; and the “STATUS”

Light Emitting Diodes (LED’s).
