Description
Exact I/O counts, firmware revision, and option package (K51) must be verified against the project configuration file and the current Woodward easYgen-3000XT technical manual before installation.
Product Introduction
When a CHP plant or multi-genset installation needs reliable paralleling and load sharing, the controller that sits in the middle of the logic is critical. The Woodward 8440-2230 is the easYgen-3500XT P1 K51 unit used for those applications—handling start/stop sequencing, synchronization, load management, and protection across multiple generator sets.
Compared with earlier 3000-series boards, the XT platform adds improved HMI visibility and expanded multi-unit capability. Sites keep this part number on the shelf because it matches the existing project files and wiring already commissioned on the plant. Always read the installed firmware and option package before ordering a spare.
Key Selling Points & Differentiators
- Designed for multi-genset paralleling and load-share schemes that can include Woodward LS-5 controllers; supports the complex operating modes common in CHP and standby power plants.
- Color graphical interface typical of the 3000XT family improves operator visibility during commissioning and fault diagnosis.
- Direct difference versus a basic single-genset easYgen-100/400 unit: this controller is built for coordinated multi-unit operation rather than simple AMF duty.
- Not recommended when the application is a single isolated genset with only basic start/stop requirements—the extra capability and cost are unnecessary.
- Every unit receives incoming visual and label inspection, power-up on a test bench, communication port check, and basic functional verification against the series test procedure. QC date and test notes are available on request.
- Configuration and set-point structure follow Woodward’s standard easYgen toolkit approach; verify against the current technical manual for the exact software revision.
Frequently Asked Questions
Can I drop this straight into an existing easYgen-3000XT panel?
Only if the firmware revision, option package (K51), and I/O mapping match the project file. Mismatched firmware forces a full reload and re-commissioning of set-points. Photograph the nameplate and export the current configuration before removal.
I have an older 3000-series controller—will the 8440-2230 be a direct swap?
Physically the mounting and many terminals are similar, but the XT platform has differences in HMI, communication ports, and software. Treat it as a related but not identical replacement; plan for configuration migration.
What power supply range does the unit accept?
The series is designed around 12/24 Vdc systems. Confirm the exact continuous and surge ratings in the OEM datasheet for the 8440-2230; reverse-polarity protection is standard on these controllers.
