L401 CONTROLLER
The L401 controller is an auto start controller that monitors the unit and indicates operational status and fault
conditions. The controller can be programmed to automatically start or stop based on time schedule, fault condition,
or load demand.
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 be shut down automatically and the LCD window will
show the fault that caused the shutdown. To resume operation, the fault condition must be resolved.
This controller also records a history of unit performance, which may be viewed at any time and will not be lost when
the controller is powered down.
