The WOODWARD 8440-2089 is a highly advanced Genset Controller from the company’s easYgen-3000XT Series. Specifically, it’s identified as the easYgen-3500XT-P2-LT. This is a powerful and versatile controller designed for managing complex paralleling applications in power generation systems, with the added capability of operating in extreme low-temperature environments.
WOODWARD 8440-2089: Genset Controller (easYgen-3500XT-P2-LT)
The easYgen-3500XT-P2-LT is designed for front-panel mounting and includes an integrated graphical display. The key differentiators for this specific model are the “P2” and “LT” designations. “P2” indicates a more advanced feature set, which often includes expanded I/O for applications like cogeneration (CHP) or complex multi-mains systems. The “LT” stands for Low Temperature, which means the controller is specifically manufactured and tested to operate reliably in ambient temperatures as low as -40 °C (-40 °F), making it ideal for installations in arctic or other cold-weather regions.

Detailed Product Description
The Woodward 8440-2089 (easYgen-3500XT-P2-LT) is a cornerstone of modern, large-scale power generation systems in extreme climates. Its design and features are focused on providing a powerful, flexible, and user-friendly control solution for complex paralleling applications, even in the harshest environments.
- Extreme Environment Capability: The “LT” variant is specifically built to withstand and operate reliably in very low temperatures, which is critical for applications in cold regions where standard electronics would fail.
- Integrated HMI and User Interface: The built-in graphical LCD and intuitive soft keys allow for easy on-site configuration, monitoring, and control without needing an external computer. This is perfect for applications where an operator needs to interact directly with the controller in the field.
- Networked and Scalable: The inclusion of redundant Ethernet and dual CAN ports is a key advantage, allowing it to integrate seamlessly into modern SCADA or DCS systems. Its ability to manage up to 32 gensets and communicate with up to 16 LS-5 circuit breaker controls makes it highly scalable for large distributed power generation sites.
- Advanced Power Management: This controller goes beyond simple start/stop functions. It provides intelligent power management features like load-dependent start/stop and import/export control, which are crucial for grid-parallel applications and for optimizing the cost of power generation.
- Comprehensive Protection: The controller provides a complete suite of protection for all components of the power system, ensuring the safety and longevity of the gensets and the stability of the electrical grid.
- Flexible Configuration: Using Woodward’s ToolKit software, users can fully customize the logic and parameters of the controller to meet the unique needs of a specific application. This often eliminates the need for an additional PLC, simplifying the control architecture.
