Controller
The PowerZone 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 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.
NOTE: See Controller Features and Functions for
descriptions of the callouts below.
