The DPG-21XX-00X digital controller is used primarily to govern diesel or gas fueled
engines of generator sets. This microprocessor based, digital controller performs across
a wide speed range and allows adjustment of set speed and gain parameters with the
built-in user interface. The COMM port provides access to all other controller settings,
allowing adaptation to each application during service and initial configuration.
Separately programmable Proportional, Integral, and Derivative gains are provided for
tailoring controller response to many engine applications. Other adjustments include
acceleration and deceleration ramp rates, idle speed set, hold time, and more.
Properly tuned, this controller delivers fast engine response to speed or load change
while providing precise stable isochronous operation.
The controller’s internal FAILSAFE reacts instantly to loss of the engine speed signal,
allowing the actuator to return to minimum fuel.
