The Woodward 8440-1855 is a specific part number that identifies an easYgen-2000 Series controller, often referenced as an easYgen-2200-5/P1. This is a powerful and versatile genset controller designed for managing and protecting generator sets in a variety of applications, including single-unit operations and potentially more complex scenarios.
WOODWARD 8440-1855: easYgen-2000 Series Genset Controller (e.g., easYgen-2200-5/P1)
The Woodward 8440-1855 belongs to Woodward’s easYgen-2000 series, a line of robust and feature-rich controls for comprehensive generator set management. It is designed to offer flexible control and protection for both the engine and the generator.
Product Overview
- Product Type: Generator Set Controller (Genset Controller)
- Manufacturer: Woodward
- Series: easYgen-2000 Series (often associated with easYgen-2200-5/P1)
- Function: This controller provides extensive 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.
- Key Features:
- Comprehensive Control: Manages engine operation (start/stop, speed, etc.) and generator output (voltage, frequency).
- Detailed Display: Features a display screen (often an LCD) to show all necessary status indicators and operational information.
- Extensive I/O: Equipped with numerous configurable terminals for connecting a wide range of sensors and actuators. For instance, it has 59 terminals, with specific terminals designated for power supply (e.g., 8-40 Vdc to terminal 53) and MPU connections (terminals 56 and 57 for positive and negative leads, respectively).
- Engine ECU Interface: Capable of communicating with electronic engine ECUs (Electronic Control Units) via CAN bus (J1939), allowing for monitoring and control of engine parameters.
- Generator Metering: Provides accurate measurement of 3-phase generator voltage, current, power (kW, kVA, kVAr), and frequency. It supports various voltage ranges (e.g., 50-130V or 131-480V for 3-phase, 3-wire settings).
- 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).
- Event Log: Stores an event log for diagnostic purposes.
- Configurability: Highly configurable to adapt to different application requirements, typically via PC software or the front panel.
Detailed Description
The easYgen-2000 series, including the 8440-1855, was a staple in Woodward’s lineup for generator control. These controllers are known for their robust design and broad feature set, making them suitable for many demanding applications. While primarily designed for individual generator control, models within this series could often integrate into more complex systems, though dedicated paralleling controllers (like the easYgen-3000 series) would be used for advanced multi-genset paralleling operations.
A service bulletin (37987 Revision A, 06/2024) indicated that a small batch of easYgen-2000/1000, DTSC-200, and LS-5 families might have experienced LCD display performance issues (e.g., blank screen, abnormal contrast, flickering) due to a non-standard soldering process. This issue affected the HMI but not other controller functions and could often be corrected by cleaning corrosion.
Applications
The Woodward 8440-1855 easYgen-2000 Series controller is commonly used in various power generation applications, including:
- Standby/Emergency Power Systems: Controlling gensets that provide backup power for facilities during grid outages.
- Prime Power Applications: Managing gensets that serve as the primary power source in remote or off-grid locations.
- Automatic Mains Failure (AMF): For applications where automatic transfer between utility power and generator power is required.
- Rental Power: Providing flexible control for mobile generator sets.
- Industrial Prime Movers: For engine-driven equipment in various industrial settings.
Obsolescence and Replacement Options
It’s important to be aware of the current status of the 8440-1855:
- Obsolescence (End-of-Life): The easYgen-2000 series, including the 8440-1855, has been designated as inactivated (End-of-Life) by Woodward. This means direct sales and new production of this specific part number are discontinued. Woodward typically takes this action due to the obsolescence of internal components.
- Limited Support: While some third-party repair and refurbishment services (like AX Control, as found in search results) may still be available for these units, direct support and new unit availability from Woodward are severely limited.
- Recommended Replacements: Woodward offers 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.
- easYgen-1000 Series (newer variants): For single-unit AMF applications, newer models within the easYgen-1000 series might also be suitable, depending on the specific feature set required.
