WOODWARD 8440-2256: easYgen-1700 AMF Genset Controller

 

The Woodward 8440-2256 easYgen-1700 is a robust and capable control unit from Woodward’s easYgen-1000 series. It’s engineered for efficient management and protection of individual generator sets in applications that require automatic transfer between utility power and generator power.

 

Product Overview

 

  • Product Type: Automatic Mains Failure (AMF) Genset Controller
  • Manufacturer: Woodward
  • Series: easYgen-1000 Series (specifically the easYgen-1700 variant)
  • Function: The easYgen-1700’s primary role is to monitor the utility (mains) power supply. In the event of an outage or unacceptable power quality, it automatically initiates the generator set, transfers the electrical load to the generator, and then, upon restoration of stable mains power, seamlessly transfers the load back to the utility and shuts down the generator. It also provides comprehensive control and protection for the generator set itself.
  • Key Features:
    • Automatic Mains Failure (AMF) Function: This is a core feature, enabling automatic detection of mains power status and controlling the genset in response to utility failures.
    • Large LCD Display: Features a large Liquid Crystal Display (LCD), which provides a clear and enhanced user experience for local monitoring, status indication, and configuration. (Note: It’s a monochrome LCD on the same physical size as the easYgen-1800, which has a color TFT).
    • On-board I/Os: Offers an adequate number of configurable inputs and outputs for connecting various engine sensors (e.g., temperature, pressure, fuel level) and controlling actuators (e.g., fuel solenoid, starter).
    • Electronic Engine Support: Includes a CAN bus (J1939) interface for direct communication with electronic engine ECUs (Electronic Control Units) from various manufacturers (such as Bosch, Cummins, John Deere, MTU, Perkins, Scania, Volvo, and Woodward). This allows for monitoring and control of engine parameters.
    • Comprehensive Protection: Provides extensive engine, generator, and utility (mains) protection functions, including over/under voltage, over/under frequency, loss of phase, phase sequence, over and reverse power, and overcurrent.
    • Power Metering: Capable of measuring and displaying 3-phase voltage, current, power parameters, and frequency for both the generator and mains supply.
    • Communication Ports: Typically equipped with standard industrial connectivity options like CAN J1939, RS-485, and USB for diagnostics, configuration, and remote communication. (Note: It lacks the Ethernet and SD card connectivity found on the easYgen-1800).
    • Event Log and Real-Time Clock: Stores events and data with a real-time clock for diagnostics, troubleshooting, and maintenance tracking.
    • Maintenance Scheduler: Features for tracking operating hours, starts, and setting maintenance reminders.
    • Switchable Parameter Sets: Can store multiple parameter sets for different AC system windings, rated voltage, frequency, current, power, and speed, providing flexibility for diverse genset applications.
    • Configuration Flexibility: Can be configured from a computer via USB or directly from the front panel with password protection.
    • Multilingual Support: Often includes multilingual capability, selectable on-site.

Detailed Description

 

The easYgen-1700 (8440-2256) is positioned as a feature-rich controller within the easYgen-1000 series, offering strong AMF capabilities. While it shares the robust platform of the easYgen-1800, it differentiates itself by omitting Ethernet and SD card connectivity, making it a cost-effective solution for applications where those specific networking and extensive data logging features aren’t essential. It provides a comprehensive solution for single-unit genset control with automatic mains failure and protection.

 

Applications

 

The Woodward 8440-2256 easYgen-1700 is commonly used in single-generator set applications requiring automatic mains failure and comprehensive control, such as:

  • Standby Power Systems: Managing gensets that provide emergency backup power for commercial buildings, small industrial sites, or critical infrastructure where automatic power transfer is crucial.
  • Prime Power Applications with Auto Changeover: In locations with an unreliable grid, it can manage the genset as the primary power source while being ready to switch to or from the grid.
  • Rental Power: Flexible control for mobile generator sets used in various standby or prime power scenarios.
  • Pumping Units: Can be adapted for engine-driven pumping units for control and indication, with the option to inhibit relays if only monitoring and alarming are needed.

 

Obsolescence and Replacement Options

 

It’s important to be aware of the current status of the 8440-2256:

  • Obsolescence: The easYgen-1000 series, including the 8440-2256 (easYgen-1700), belongs to an older generation of Woodward controllers. While a precise “End-of-Life” (EOL) notification for this specific part number isn’t immediately prominent, it’s consistent with industry practice that older series are eventually superseded by newer models with enhanced features, updated components, and improved connectivity. As of July 2025, availability and direct support for such models are becoming increasingly limited.
  • No Direct Substitute: There is typically no direct, one-for-one substitute with the exact same form factor and identical features for older, specific part numbers like the easYgen-1700.
  • Recommended Replacements: Woodward continually introduces more advanced and feature-rich controllers. The likely modern equivalents or next-generation controllers for similar single-genset AMF applications would be found within the easYgen-1000 series (newer variants like easYgen-1800XT or newer generations) or the easYgen-3000XT series. These newer controllers typically offer:
    • Improved processing power and memory for more complex control algorithms.
    • Enhanced communication options, including more robust Ethernet capabilities (often standard on newer models) and expanded USB functionality.
    • More advanced diagnostic and protection features.
    • Updated display interfaces (often color TFT) and potentially more user-friendly configuration tools with modern software.
