Integrated Control Architecture for Multi-Source Power Systems
In projects involving multiple generators, utility feeders, and bus-tie breakers, control architecture directly impacts system stability and commissioning time. The Woodward easYgen-3000XT series is designed as a centralized genset controller that integrates synchronization, protection, load sharing, AVR control, and process PID functions into one unit.
This eliminates the need for additional in many designs, as the controller already provides configurable PID loops and logic handling. It supports both generator circuit breakers and mains breakers, and in higher models, group breaker control is also included.
The platform is also designed for hybrid systems, allowing coordination with photovoltaic systems, battery storage, and inverter controllers such as easYi. This makes it suitable for microgrid projects where multiple energy sources must be managed in parallel.

Control Functions Based on Actual Grid and Genset Conditions
From an operational standpoint, the Woodward easYgen-3000XT series supports the core control modes required in real installations. These include:
Synchronization (generator, mains, and group breakers depending on model)
Load-dependent start/stop
Import/export control for both kW and kvar
Dead bus paralleling and run-up synchronization
Mains parallel operation with multiple units
The controller also supports up to 48 devices on a load-sharing network when used with LS-5, and extended configurations with LS-6XT for larger systems.
Measurement accuracy is Class 0.5 for voltage and current, with true RMS sensing. Voltage inputs support multiple ranges (100 VAC, 400 VAC, and up to 600 VAC on higher models), and current inputs are configurable for 1 A or 5 A with a setting range up to 32,000 A. This allows the same controller platform to be used across different generator ratings without hardware changes.

Protection Functions Aligned with ANSI Standards
Protection is implemented according to widely used ANSI codes, which simplifies engineering documentation and compliance. The easYgen-3000XT includes:
Voltage and frequency protection (59 / 27 / 81O / 81U)
Reverse and reduced power protection (32 / 32R / 32F)
Overcurrent and time-overcurrent protection (50 / 51 / 51V)
Ground fault protection via measured ground current (50G)
Unbalanced load detection (46)
Synch check (25) and ROCOF / phase shift protection (78)
Engine-related protections such as overspeed (12), underspeed (14), cylinder temperature monitoring, and excitation failure are also integrated.
This level of protection coverage allows the controller to replace separate protection relays in many genset panels, reducing panel space and wiring complexity.

Hardware and Interface Configuration for System Integration
The easYgen-3000XT series provides multiple communication and I/O options for integration into automation systems. Depending on the model, it includes:
CAN bus interfaces (up to 3 ports, configurable for CANopen or J1939)
RS-485 with Modbus RTU
Ethernet with Modbus TCP (up to 3 ports in higher models)
USB interface for configuration
I/O capacity varies by model, with up to:
32 discrete inputs and 32 outputs via CANopen expansion
10 analog inputs and 4 analog outputs (±10 V / ±20 mA / PWM)
Support for resistive sensors (VDO, Pt100, Pt1000) and standard signal ranges (0–1 V, 0–20 mA)
The controller also supports display and evaluation of J1939 parameters (up to 100 SPNs), which is useful when interfacing with modern engines.
For environmental conditions, the unit operates from -20°C to 70°C (or down to -40°C with low-temperature variants), with 95% non-condensing humidity tolerance. The front protection rating reaches IP66 with proper mounting, which is relevant for outdoor or industrial panel installations.

Practical Considerations for Engineering and Lifecycle
From a project execution perspective, the easYgen-3000XT series allows on-site configuration and real-time parameter changes, which reduces dependency on pre-programmed logic. This is particularly useful during commissioning when load conditions and system behavior need adjustment.
The controller can also be used as a replacement for earlier Woodward or third-party systems, minimizing retrofit effort.
Power supply flexibility (8–40 VDC) and low intrinsic consumption (max. 22 W) simplify auxiliary power design. In addition, integrated logic and analog handling reduce the need for external modules, which directly impacts automation spare parts planning and long-term maintenance.
For rental and mobile genset applications, optional functions such as operation counters and switchable parameter sets are available, allowing usage tracking and billing integration.

Recommended easYgen-3000XT Models by Project Type
Based on system size and functional requirements, the following selection is typically used in projects:

easYgen-3100XT / 3200XT

WOODWARD EASYGEN 3200-5P2 8440-1843 Genset Controller

Suitable for single genset control or simple paralleling with limited I/O and communication requirements. Typically used in small industrial or standby applications.
easYgen-3400XT
Applied in medium-scale systems where additional Ethernet communication, higher I/O capacity, and group control are required. Supports more complex synchronization schemes.
easYgen-3500XT

Woodward EASYGEN-3500XT-P1 8440-2082 Operator Interface

WOODWARD EASYGEN-3500-5 8440-1934 AUTOMATIC MAIN F

For projects involving multiple generators, busbar segmentation, or hybrid energy systems, the easYgen-3500XT provides the necessary control depth and interface capacity without adding external control layers.
