Technical Parameters & Selection Guide

Selection Criteria:

Choose the 8440-1934 easYgen-3500-5 when your application requires multi-genset paralleling, mains synchronization, or load sharing capabilities beyond basic start/stop control. This model is specifically designed for installations with 2 or more generator sets operating in parallel configuration, or single gensets requiring utility grid synchronization for peak shaving or co-generation applications.

For standalone genset applications without paralleling requirements, consider the easYgen-3500 standard model (8440-1843). For applications requiring additional I/O expansion or advanced communication features, evaluate the 8440-2087 variant with extended connectivity options.

Verify compatibility with your engine's governor interface (electronic or mechanical) and ensure current transformer ratios match the controller's 5A input specification. Consult factory application engineering for custom configurations involving non-standard voltage ranges or specialized protection requirements.

Frequently Asked Questions

What is the maximum genset capacity this controller can manage?
The 8440-1934 is rated for generator sets up to 3,000 kVA per unit. Total system capacity is limited only by the number of paralleled units (up to 32 gensets), enabling power plants exceeding 90 MW when fully configured. Current transformer ratios must be selected appropriately for the specific genset amperage rating.

Can this controller interface with both diesel and natural gas engines?
Yes, the easYgen-3500-5 supports diesel, natural gas, propane, and bi-fuel engine configurations through programmable fuel type selection. Governor interface compatibility includes Woodward electronic governors (2301A, ProAct, etc.) as well as mechanical governor systems via actuator control outputs.

How does remote monitoring capability work with existing SCADA systems?
The controller's Modbus RTU interface (RS-485) provides direct connectivity to most industrial SCADA platforms including Schneider Electric, Siemens, and Rockwell Automation systems. Standard Modbus register mapping is documented in the technical manual, and custom register configurations can be programmed using the ToolKit software for specialized integration requirements.

What installation requirements are needed for proper operation?
Professional installation by qualified electrical technicians is strongly recommended. Minimum requirements include proper panel cutout dimensions (274×178mm), adequate ventilation for ambient temperature control, shielded wiring for communication cables, and appropriately sized current transformers. Compliance with local electrical codes (NEC, IEC) and manufacturer installation guidelines is mandatory for warranty validation.

Is the controller compatible with renewable energy integration?
While primarily designed for genset control, the easYgen-3500-5 can coordinate with solar/wind systems in hybrid power configurations when used with appropriate power management controllers. The mains-parallel synchronization feature enables seamless integration with grid-tied renewable systems, though dedicated renewable energy controllers may be required for optimal performance in complex hybrid installations.

What training is available for maintenance personnel?
Woodward offers comprehensive training programs ranging from basic operator courses to advanced troubleshooting and configuration workshops. Online training modules, webinars, and hands-on classroom sessions are available through Woodward's global training network.
