Digital Controller
The MGG450 is equipped with a Motortech® All-In-One
controller that monitors the unit and indicates operational
status and fault conditions. The unit leaves the factory
with the controller warning set at 105% load and
shutdown set at 110% load.
The controller constantly monitors vital generator and
engine functions for a number of preprogrammed alarm
and fault conditions. When a fault condition occurs, the
engine can shut down automatically and the display
screen will show the fault that caused the shut down. The
fault condition must be resolved to resume unit operation.
This controller records a history of unit performance,
which may be viewed at any time and will not be lost
when the controller is powered down.
