Application Fields
The easYgen-3200-5 is used in sophisticated energy management scenarios, including:
- Data centers and hospitals requiring automated mains failure (AMF) logic.
- Distributed generation and microgrid peak shaving.
- Marine power management systems for shipboard generators.
- Rental power modules where multi-unit synchronization is required.
- Combined Heat and Power (CHP) plant automation.
Usage Instructions
The Woodward 8440-1667 should be flush-mounted into a control cabinet door. Wiring involves connecting the voltage sensing inputs directly to the generator and mains buses (using potential transformers if necessary) and connecting current transformers (CTs) for load monitoring. Use the Woodward Toolkit software via the RS-232 or USB port for comprehensive configuration of PID loops, breaker timing, and protective relay settings. Ensure that the CANbus termination resistors are correctly placed if the unit is part of a load-sharing network. Calibration of the internal phase-angle compensation is required for accurate synchronization.
Frequently Asked Questions (Q&A)
Q: Does the 8440-1667 support remote monitoring? A: Yes. Through its Modbus RTU and Ethernet (via external gateway) capabilities, the unit can be integrated into SCADA systems or monitored remotely via the Woodward remote panel (RP-3000).
Q: Can this controller manage a “Bumpless Transfer”? A: Absolutely. It supports several modes including Open Transition, Closed Transition (overlap), and Soft Loading, which allows the generator to take over the load from the mains without a momentary power interruption.
Q: What is the difference between the 3200 and the 3500 series? A: While they share many core functions, the 3200-5 (like the 8440-1667) typically features a plastic housing and high-quality graphical display, whereas the 3500 series often comes in a ruggedized metal housing with a different display interface for extreme environments.
