The WOODWARD 8440-2086 is a highly advanced Genset Controller from the company’s easYgen-3000XT Series. Specifically, it’s identified as the easYgen-3500XT-P1-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 8440-2086: Genset Controller (easYgen-3500XT-P1-LT)
The easYgen-3500XT-P1-LT is designed for front-panel mounting and includes an integrated graphical display. The key differentiator for this model is the “LT” designation, which stands for Low Temperature. This indicates that 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 cold-weather regions.

Detailed Product Description
The Woodward 8440-2086 (easYgen-3500XT-P1-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.
