APECS* DPG-2401 Series

Digital Controllers for EFC Valves
APECS® Programmable Controllers for Isochronous Generators with Load Sharing Capability

The DPG-2401-00X digital controller is designed for use with the electronic fuel control (EFC) valve used on Cummins engines fitted with PT (position throttle) type fuel pumps. This microprocessor based, digital controller performs across a wide speed range and allows adjustment of all controller features through the built-in user interface.
Properly tuned, this controller delivers fast engine response to speed or load change while providing precise stable isochronous operation.

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, startup and torque limits, idle speed set, and idle hold time.

The DPG-2401-00X controller can also provide droop speed control with 100 user Selectable droop levels. The controller’s internal FAILSAFE reacts instantly to loss of the engine speed signal or loss of remote speed potentiometer signal.

Features include:

• Automatic calibration of the remote speed potentiometer
• Isochronous speed control
• Droop operation: 0 to 10% of set speed with 1/10 percent resolution
• User friendly / operator adjustable
• Precision frequency control: 0.25%
• Superior temperature stability
• Reverse battery protection
• Input voltage range: 9–30 Vdc
• Smoke control on start up
• Remote setup
• Serial communication port
