The Woodward 8440-2252 is a specific part number that identifies an easYgen-600 controller. This is a compact, automatic start/stop generator set controller that is part of Woodward’s easYgen-100 series, designed for various single-unit power generation applications.
WOODWARD 8440-2252: easYgen-600 Genset Controller
The Woodward 8440-2252 easYgen-600 belongs to Woodward’s easYgen-100 series of controls, which are specifically developed for reliable and efficient management of single generator sets in isolated stand-by or prime power applications.
Product Overview
- Product Type: Generator Set Controller (Genset Controller) / Automatic Start/Stop Controller
- Manufacturer: Woodward
- Series: easYgen-100 Series (specifically the easYgen-600 variant)
- Function: The easYgen-600 is designed to automatically or manually start, stop, control, and protect a single generator set. It includes built-in algorithms and logic for robust genset operation.
- Key Features:
- Automatic Start/Stop: Capable of initiating or shutting down the genset based on remote signals.
- LCD Display: Features a clear Liquid Crystal Display (LCD) for local monitoring and configuration.
- Configurable I/Os: Provides a suitable number of on-board inputs and outputs that can be configured to connect various sensors and actuators.
- Electronic Engine Support: Includes an engine ECU (Electronic Control Unit) interface, typically via CAN bus (J1939), allowing it to communicate with electronic engines for monitoring and control of parameters like water temperature, oil pressure, speed, and fuel consumption. It directly supports several ECUs from manufacturers like Bosch, Cummins, John Deere, MTU, Perkins, Scania, Volvo, and Woodward.
- Comprehensive Protection: Offers extensive engine and generator protection functions, including over/under voltage, over/under frequency, loss of phase, reverse power, and overcurrent.
- Power Metering: Capable of measuring and displaying generator parameters such as 3-phase voltage, current, power, and frequency.
- Communication Ports: Equipped with common industrial connectivity options such as CAN J1939, RS-485, and USB.
- Event Log and Real-Time Clock: Stores an event log with a real-time clock for diagnostics and troubleshooting.
- Maintenance Scheduler: Includes features for tracking operating hours, starts, and scheduling maintenance activities.
- Switchable Parameter Sets: Can store multiple parameter sets for different AC system windings, rated voltage, frequency, current, power, and speed, which is useful for mobile genset applications.
- Configuration: Can be configured from a computer via USB or directly from the front panel with password protection.
- Dedicated Relays: Includes dedicated relay outputs for cranking and fuel solenoid.
Detailed Description
The easYgen-600 (8440-2252) is a highly versatile and cost-effective controller within the easYgen-100 series, providing essential control and protection for standalone generator sets. It’s suitable for OEM genset packagers and system integrators due to its comprehensive feature set and ease of configuration.
While robust for single-unit operation, it does not typically include Automatic Mains Failure (AMF) functionality or advanced paralleling capabilities. For those functions, higher models in the easYgen series (e.g., easYgen-1000 series for AMF or easYgen-3000 series for paralleling) would be required. Its ability to directly interface with various engine ECUs via CAN bus streamlines integration and offers sophisticated monitoring of electronic engines.
Applications
The Woodward 8440-2252 easYgen-600 is commonly used in single-generator set applications that require automatic or manual start/stop control and comprehensive protection, such as:
- Isolated Standby Power: Managing gensets that provide backup power during grid outages (can interface with external Automatic Transfer Switches).
- Prime Power: Controlling gensets that operate as the primary power source in remote or off-grid locations.
- Rental Power: Flexible control for mobile generator sets used in various temporary power needs.
- Pumping Units: Can be applied on engine-driven pumping units as a control and indicating instrument, with relays inhibited if only indication and alarming are needed.
Obsolescence and Replacement Options
It’s important to be aware of the current status of the 8440-2252:
- Obsolescence: The easYgen-100 series, including the 8440-2252 (easYgen-600), is an older product line within Woodward’s portfolio. While specific “End-of-Life” (EOL) notifications might not be as explicit for every single part number as for some other older Woodward products, this series has largely been superseded by newer models with enhanced features, updated components, and improved connectivity. Availability and direct support for such models become increasingly limited over time.
- No Direct Substitute: There is generally no direct, one-for-one substitute with the exact same form factor and identical features for the easYgen-600.
- Recommended Replacements: Woodward continuously updates its product lines to offer more advanced and feature-rich controllers. The likely modern equivalents or next-generation controllers for similar single-genset applications would be found within the easYgen-300XT series or easYgen-1000 series (e.g., easYgen-1400/1600 models, particularly if Automatic Mains Failure (AMF) functionality is desired in the new solution). These newer controllers typically offer:
- Improved processing power and memory.
- Enhanced communication options (e.g., more robust Ethernet capabilities, expanded USB functionality).
- More advanced control algorithms and diagnostic capabilities.
- Updated display interfaces and potentially more user-friendly configuration tools.
