Brief Product Description

Woodward 8440-2085 is the easYgen-3500XT-P1 high-performance genset controller belonging to the easYgen-3000XT series, designed for complex multi-generator paralleling and load-sharing power management applications. This intelligent controller integrates generator speed, voltage and mains monitoring, automatic synchronization, load sharing and comprehensive engine/generator protection functions. It is equipped with dual CANBus, RS485 and E-Net Modbus TCP communication ports, supporting connection with up to 16 LS-5 breaker controllers for multi-busbar power distribution control. With a wide operating temperature range of -20°C ~ +70°C and robust hardware design, it adapts to harsh power house environments. It supports redundant control architecture for high-reliability power generation systems. As a legacy power control spare component, it is available as fully-tested surplus and refurbished units for maintenance and retrofit of existing genset parallel control systems.

Core Product Functions

• Automatic start/stop, speed and voltage regulation for diesel and gas generator sets
• Generator & mains synchronization, paralleling and precise load sharing for multiple gensets
• Complete protection functions: over/under voltage, over/under frequency, reverse power, overcurrent and engine fault protection
• Multiple communication interfaces: dual CANBus, RS485 serial port and Modbus TCP E-Net Ethernet port
• Supports LS-5 breaker controllers to realize multi-unit control for up to 32 generators across 32 bus sections
• Three configurable PID loops for speed and voltage bias adjustment to optimize power stability
• Real-time data recording, event logging and fault timestamp storage for post-failure analysis
• Supports redundant control configuration to enhance reliability for critical power supply applications

• Local HMI display and remote touch panel connection for parameter setup, status monitoring and alarm viewing

Application Scenarios

• Offshore platform generator control cabinets and island-mode power distribution systems
• Legacy genset control system upgrade, retrofit and multi-unit parallel power management projects
• Spare replacement generator controller for maintenance and troubleshooting of existing Woodward easYgen installations

FAQ (Frequently Asked Questions)

• Q: Controller fails to synchronize generator with mains after installing 8440-2085?
  A: Check PT voltage wiring, CT connections, synchronizing parameter settings, communication bus status and generator speed/voltage regulator configuration.
• Q: Does Woodward 8440-2085 support hot-swap replacement while genset is running?
  A: No, it is not hot-swappable. Disconnect power and follow lockout-tagout procedures before replacing the controller.
• Q: Can this 8440-2085 (easYgen-3500XT-P1) be used for single standalone generator only?
  A: Yes, it can work for single genset, but its main advantage is complex multi-unit paralleling and multi-section bus control applications.
• Q: What is the difference between P1 and P2 versions of easYgen-3500XT?
  A: P1 (8440-2085) is designed for complex paralleling with LS-5 breaker connectivity; P2 targets simpler parallel applications without LS-5 support.
• Q: Is Woodward 8440-2085 available for brand-new genset control projects?
  A: This legacy genset controller has reached end-of-life. Only fully-tested surplus and refurbished units are offered for existing-site maintenance and retrofit tasks.
