Features

• Full connectivity of up to 496 gensets sorted into 16 groups of 31 gensets each. One GC

3400XT per group

• Redundant or single load share communication over CAN/Ethernet between easYgen and

group controller

• Redundant or single load share communication over Ethernet among group controllers

• Redundant or single load share communication over Ethernet between GC and LS-6XT.

• Dedicated Ethernet Modbus TCP communication line to external Modbus master (PLC, SCADA

etc.)

• Active and reactive load sharing and load dependent start/stop (LDSS) management of the

whole fleet

• LDSS algorithm is emulated with a PC software and the final settings are transferred directly to

the GC

• Supports synchronization and soft loading/unloading of a tie- or mains breaker

• Phase angle compensation (Vector group adjustment) in case transformers are used in the

application

• Comprehensive monitoring of all interfaces, loss of redundancy and breaker feedback plausi

bility check

• “System Update” function for troubleshooting and fast commissioning

• Time / Date synchronization over Simple Network Time Protocol (SNTP)

• Woodward ToolKit™ software for flexible setup from a single connection to the network. The

ToolKit can be accessed either via USB, or via Ethernet, or via CAN ports..

The GC-3400XT is based on a scalable multi-master control concept to combine up to 31 easY

gen-3000XT equipped gensets with one group controller in a group. The groups are scaled up

to 16. i.e. a total up to 496 gensets can be managed in an application. The data flow within the

group is handled by CAN or Ethernet or CAN & Ethernet bus. The group controller collects and

sorts the data of its group and acts like a “Big Genset” control to the other GCs. The data flow

among the group controllers is handled by second communication bus Ethernet B or Ethernet C

or Ethernet B & C. Through the decoupling of the overall data flow, the bus bandwidth is kept low

and the single genset operation is kept safe, should a group controller become the point of failure.

Furthermore, the group controller may handle a group breaker, to synchronize or prioritize dead

busbar closing. Additionally, the group controller supports the synchronization and soft loading/

unloading of a tie- or mains breaker. Comprehensive diagnostics, monitoring and system update

function are implemented to help fast com-missioning of the system.

Woodward’s easYgen-3400XT/3500XT 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 operator control panel.

stand-ardized software that is simple to configure, yet easily customizable for individual applica

tions. Peer-to-peer communication between the controls and load share line redundancy at each

level ensures single-fail-safe op-eration of your power generation control system.

The easYgen-3200XT application range spans from isolated operation of a single genset to load sharing

of up to 32 gen-sets in islanded and/or parallel operation with a single utility. It combines complete

engine-generator control and protection with advanced, peer-to-peer paralleling functionality and

innovative features in a robust,

attractive, user-friendly and all-in-one package. Its integrated LogicsManager™ and AnalogManager™ pro

grammable logic functionalities provide outstanding application flexibility and can often eliminate the

need of an additional PLC control, yet can easily integrate with SCADA or PLC-based control systems

where desired.

The easYgen-3200XT also comes without a display in a rugged metal housing suitable for back panel

installations. A sophisticated touch screen remote panel (RP-3000XT) complements it as an operator

control panel. A version of easYgen-3200XT (easYgen-3200XT-P1-LT) is designed to operate down to -400

Easy-to-use software tools simplify configuring the easYgen-3000XT Series controllers while making it

easy to customize the unit for specific applications.  These tools include:

FlexAppTM– This feature provides the tools to easily configure the number of operated breakers: None,

Gener

ator Circuit Breaker (GCB), and Mains Circuit Breaker (MCB).

LogicsManagerTM & AnalogManagerTM (LM & AM) – Woodward’s LM/AM enables to customize the

Woodward raised the standard in genset paralleling control and power management system with the

easYgen 3000XT Series controllers. These controllers come with standardized software that is simple to

configure, yet easily customized for individual applications. Enhanced connectivity enables fast and secure

interfacing to other controls and communications systems while the enhanced hardware is a drop-in

replacement for previous generation easYgen-3000 Series Controls.

The easYgen-3000XT Series controllers operate gen-sets of all sizes and applications. These controllers in

clude specifically designed algorithms and logic to start, stop, control, and protect the genset, circuit

breaker and the utility, where applicable. It allows standardizing on a single, affordable genset controller

for distributed power generation applications. The applications range from single stand-alone emergency

backup power to parallel load sharing of multiple gen-sets in complex, segmented distribution systems

with multiple utility feeds and tie breakers. Woodward’s easYgen-3000XT Series paralleling genset

controllers provide exceptional versatility and value for OEM switchgear builders, generator packagers,

and system integrators.
