Application Fields
The DPG-2104 is a versatile controller utilized across various engine-driven platforms, including:
- Small to medium-sized generator sets (Gensets) for standby and prime power.
- Off-highway industrial equipment requiring constant speed governance.
- Pump drive systems in agricultural and irrigation applications.
- Mobile service equipment and portable power units.
Usage Instructions
To install the Woodward DPG-2104, mount the controller in a location that minimizes exposure to direct heat sources while remaining accessible for wiring. The wiring harness must connect the power source, the Magnetic Pickup (MPU) for speed sensing, and the actuator for fuel control. During the commissioning phase, use the Woodward configuration software to set the number of flywheel teeth and the desired rated speed. Fine-tune the PID (Proportional, Integral, Derivative) settings to ensure the engine recovers quickly from load steps without excessive overshoot or hunting.
Frequently Asked Questions (Q&A)
Q: Does the DPG-2104 support isochronous and droop modes? A: Yes. The controller is capable of isochronous operation for precise frequency control, as well as droop mode for applications where multiple generators need to share a load without a dedicated communication link.
Q: What happens if the speed sensor (MPU) signal is lost? A: The DPG-2104 features a fail-safe design. If the speed signal is lost during operation, the controller will immediately drive the actuator to the minimum fuel position (zero current) to shut down the engine and prevent an overspeed condition.
Q: Can I configure this unit without a laptop? A: While the PC software provides the most comprehensive interface, the unit can also be configured using a Woodward handheld programmer for basic field adjustments and parameter monitoring.
