Woodward's easYgen-3500XT Series paralleling genset controllers provide exceptional versatility and value for OEM switchgear builders, generator packagers, and system integrators. The easYgen-3500XT combines complete engine-generator control and protection with advanced, peer-to-peer paralleling functionality and innovative features in a robust, attractive and user-friendly package. Its integrated LogicsManager™ programmable logic functionality provides outstanding application flexibility and can often eliminate the need for additional PLC control, yet can easily integrate with SCADA or PLC-based control systems where desired.
The easYgen-3500XT gives you the advantage of standardizing on a single, affordable genset controller for many different distributed power generation applications--from stand-alone emergency backup power to parallel load sharing of up to 32 gensets in complex, segmented distribution systems with multiple utility feeds and tie breakers.
Woodward’s easYgen-3400XT/3500XT K51 is an exceptionally versatile genset control with complete engine-generator control and protection, genset breaker synchronization, dead bus arbitration and isochronous/droop load share capabilities. The easYgen-3500XT is available in two packages, P1 and P2, both are compatible to work with GC-3400XT. Both the packages are available without a display in a rugged metal housing suitable for back panel installations. A sophisticated touch screen remote panel (RP-3000XT) complements them as an op-erator control panel.
Common easYgen-3500XT applications: 
  • Emergency standby: data centers, hospitals, commercial and industrial facilities
  • Distributed Generation (DG): utility-dispatchable power for peak demand response
  • Islanded prime-power: oil & gas exploration, marine, remote villages, rental/mobile
  • Microgrid: military, government, net-zero communities, universities
  • Utility paralleling: peak shaving, demand curtailment
  • Cogeneration (CHP): wastewater treatment, biogas production/containment
  • Switchgear upgrades: generator control retrofit to add load sharing/paralleling capability
easYgen-3500XT Features & Benefits
  • All easYgen-3500XT Series models include these standard features:
  • True RMS voltage and current sensing (gen, bus and mains) for reduced susceptibility to harmonics
  • CAN network communication/control to engine ECU (standard SAE-J1939 protocol and several proprietary engine OEM protocols are supported)
  • Serial Modbus RTU (slave) communication for SCADA annunciation and external control
  • Configuration via PC/laptop with Woodward ToolKit service tool
  • Connectivity with the RP-3500XT Remote Panel for complete annunciation, control and configuration of the easYgen-3500XT controller, over CANopen protocol at up to 250m distance
  • Compliance agency/marine* approvals: CE, UL/cUL, CSA, BDEW, ABS, Lloyd's Register (* see marine package for further approvals)
The easYgen-3500XT Series provide:
  • AMF (automatic mains failure) detection, decoupling and emergency run with dead bus close
  • Automatic synchronization: phase-match, positive/negative slip-frequency, run-up (dead field) paralleling
  • Circuit breaker close/open control: GCB only, GCB and MCB (ATS function), or external (no) control     
  • Proportional load sharing (isochronous or droop) of up to 32 gensets, regardless of individual size
  • Base loading, import/export control, asymmetrical loading (through external base load input)
  • Automatic load dependent start/stop for improved generation system efficiency
  • Asynchronous (induction) generator control
  • Engine and generator protection functions, with fully programmable settings
