Description
Product Overview
The Woodward 8440-2082 is an easYgen-3200XT-P1 generator set controller designed for power-generation systems that require engine-generator monitoring, breaker control, synchronization, and coordinated load management. It belongs to the easYgen-3000XT family and includes a color display with operator controls. Depending on the application configuration, it can support standalone generator operation or participate in a system with multiple paralleled generator sets. The controller is intended for applications where generator availability, electrical measurements, and breaker sequencing must be coordinated through a defined control strategy.
The controller uses a nominal 12/24 V DC supply and has a documented operating input range of 8–40 V DC. Its feature set includes synchronization functions, active and reactive power control, configurable PID controllers, and communication with engine control units. Product documentation also identifies support for SAE J1939 and serial communication options, although the available interfaces and enabled protocols should be confirmed against the exact hardware configuration. The model is listed for systems with up to 32 paralleled generators, but actual capacity depends on network architecture, application settings, and the wider control system.
For a replacement project, matching the part number is only the first step. Verify the existing controller’s application file, firmware or software compatibility, current-transformer inputs, voltage sensing, breaker wiring, and engine communication setup. Also confirm the required operating mode and whether the unit is configured for standalone, master, or slave operation. The 8440-2082 is listed with an operating temperature range of −20°C to +70°C; do not confuse it with lower-temperature variants intended for harsher environments. Before ordering, confirm the display, mounting arrangement, actual condition, available test records, and warranty with the supplier.
Product Introduction
Generator-controller replacement is not simply a matter of restoring a display and powering up. The Woodward 8440-2082 coordinates electrical measurements, synchronization, and breaker logic, so a mismatch in settings or wiring can prevent safe generator connection or load sharing.
With an 8–40 V DC input range and support for multi-generator configurations, this controller can suit a range of power-generation systems. Verify the installed application, communication interfaces, and synchronization settings before commissioning.

Frequently Asked Questions
1. What is Woodward 8440-2082 used for?
It is an easYgen-3200XT-P1 generator controller used for engine-generator monitoring, synchronization, breaker control, and power management. Depending on its configuration, it can operate a single generator or participate in a multi-generator system.
2. Can the 8440-2082 operate on a 24 V DC supply?
Yes. It is designed for nominal 12/24 V DC systems, with a published input range of 8–40 V DC. Verify the supply’s voltage during cranking and other transients, along with polarity, protection, and grounding requirements.
3. Can I hot-swap this generator controller?
Do not assume hot-swap capability. Replacing a controller can affect generator protection, breaker commands, synchronization, and load sharing. Follow the approved shutdown or transfer procedure, and ensure the generator cannot connect to a bus under unsafe conditions during replacement.
4. Does the 8440-2082 support firmware v3.1?
Compatibility with a specific firmware version cannot be confirmed from the part number alone. Check the controller’s installed software or firmware revision, the ToolKit version, and the application file requirements against the applicable Woodward documentation before upgrading.
5. Can this controller manage 32 paralleled generators?
Published listings identify support for up to 32 paralleled generators. The practical limit depends on the application configuration, communication network, controller roles, and system design. Confirm the supported topology and required licenses or configuration options for the specific installation.
6. Will replacing the controller preserve the existing settings?
Not automatically. Before removing the installed unit, back up the application and record the hardware revision, communication parameters, generator ratings, CT/VT ratios, synchronization settings, and breaker logic. Restore and validate the application using the approved engineering process, then conduct functional and protection checks before returning the generator to service.
7. What should I verify when buying a replacement?
Request the complete nameplate details, confirmation of part number 8440-2082, display and connector photographs, condition disclosure, and available test documentation. For used or refurbished units, ask whether the display, power-up diagnostics, inputs, communications, and breaker-control functions were tested. Confirm actual condition with supplier and obtain written warranty terms before purchase.
