WOODWARD 8440-1858: easYgen-2000 Series Genset Controller (e.g., easYgen-2200-5/P2)

The Woodward 8440-1858 belongs to Woodward’s easYgen-2000 series, a line of robust and feature-rich controls for extensive generator set management. It’s engineered to provide flexible control and protection for both the engine and the generator, supporting advanced communication and integration features.

Product Overview

• Product Type: Generator Set Controller (Genset Controller)
• Manufacturer: Woodward
• Series: easYgen-2000 Series (specifically associated with easYgen-2200-5/P2)
• Function: This controller offers comprehensive control, monitoring, and protection functions for generator sets. It can manage engine start/stop sequences, generator voltage and frequency, and monitor various parameters for both the engine and the generator. This specific model (P2) often implies advanced paralleling capabilities.
• Key Features:
  • Comprehensive Control: Manages engine operation (start/stop, speed, etc.) and generator output (voltage, frequency).
  • Detailed Display: Features an integrated display screen (typically a backlit LCD) to show all necessary status indicators, operational data, and alarm messages.
  • Extensive I/O: Equipped with numerous configurable terminals for connecting a wide range of sensors and actuators, allowing for adaptable system integration.
  • Electronic Engine Support: Capable of communicating directly with electronic engine ECUs (Electronic Control Units) via CAN bus (J1939), enabling detailed monitoring and control of engine parameters.
  • Generator Metering: Provides accurate measurement of 3-phase generator voltage, current, power (kW, kVA, kVAr), and frequency.
  • Protection Functions: Offers comprehensive protection for both the engine (e.g., overspeed, low oil pressure, high temperature) and the generator (e.g., over/under voltage, over/under frequency, overcurrent, reverse power, phase sequence).
  • Communication Capabilities: Features advanced interface capabilities for communication at various levels, from the genset to system networks and remote desktops. This often includes support for:
    • CANopen: For peer-to-peer load sharing among multiple gensets.
    • J1939: For engine ECU communication.
    • Modbus RTU: For integration with PLCs, HMIs, and SCADA systems.
    • Modem support: For remote control and programming via PC (using Woodward ToolKit software).
  • Event Log: Stores a detailed event log for diagnostic purposes and troubleshooting.
  • Configurability: Highly configurable via PC software (such as Woodward’s ToolKit-SC) or directly from the front panel.

Detailed Description

The easYgen-2000 series, including the 8440-1858, was a cornerstone of Woodward’s offerings for generator control, particularly known for its strong communication capabilities and flexibility in supporting various power generation schemes. These controllers are designed for robust and reliable operation in demanding industrial environments. They can manage individual generator sets, and through CANopen, can also participate in synchronized load sharing with multiple gensets in island operation or parallel operation with a utility. This series also features integrated load-dependent start/stop programming for optimized fuel efficiency in multi-genset applications.

It’s worth noting that some units from the easYgen-2000 series might have experienced LCD display performance issues (e.g., blank screen, abnormal contrast) due to a specific manufacturing process. However, this issue generally affects only the HMI and not the core control functionality, and it could often be resolved through specific servicing.

Applications

The Woodward 8440-1858 easYgen-2000 Series controller is commonly used in a wide range of power generation applications, including:

• Standby/Emergency Power Systems: Controlling gensets that provide backup power for commercial, industrial, and critical facilities during grid outages, often with Automatic Mains Failure (AMF) functionality.
• Prime Power Applications: Managing gensets that serve as the primary power source in remote or off-grid locations.
• Peak Shaving and Import/Export Control: Optimizing energy costs by running gensets during peak demand periods or controlling power flow with the utility.
• Co-generation / CHP (Combined Heat and Power): Integrating gensets into systems that produce both electricity and useful heat.
• Load Sharing Applications: Synchronizing and sharing load among multiple generator sets in island or parallel-to-grid operations.
• 

Obsolescence and Replacement Options

It’s crucial to be aware of the current status of the 8440-1858:

• Obsolescence (End-of-Life): The easYgen-2000 series, including the 8440-1858, has been designated as inactivated (End-of-Life) by Woodward. This means direct sales and new production of this specific part number are discontinued. This action is typically due to the obsolescence of internal components.
• Limited Support: While some third-party repair and refurbishment services may still offer support for these units, direct support and new unit availability from Woodward are severely limited.
• Recommended Replacements: Woodward has introduced newer, more advanced generations of genset controllers to replace the easYgen-2000 series. The recommended modern replacements typically include:
  • easYgen-3000XT Series: This series is the direct successor and offers enhanced features, improved connectivity (including robust Ethernet), advanced control algorithms, and a more modern user interface. It can handle a wide range of single-unit and paralleling applications, including those previously covered by the easYgen-2000 series.
  • easYgen-1000 Series (newer variants): For simpler single-unit AMF applications, newer models within the easYgen-1000 series might also be suitable, depending on the specific feature set required.
