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 shutdown
automatically and the Liquid Crystal Display (LCD) window will display the fault that caused the shutdown; 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 units performance which may be viewed at any time and will not be 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).
