Woodward easYgen-3400-5 P2 8440-2078D Overview

The easYgen-3400 series is designed to manage single or multiple generator sets and allow them to run stand-alone or in parallel with the grid. It combines protection, control, and monitoring into one controller.

The part number 8440-2078D specifically refers to a cabinet-back mounting version without display and with 5A CT inputs.

Main Functions

1) Generator Control & Automation

This controller can automatically start, stop, and monitor gensets while protecting them from abnormal operating conditions.

Typical control functions include:

• Engine start/stop sequencing
• Voltage and frequency control
• Power and power-factor control
• Automatic mains failure (AMF) operation
• Peak shaving and load shedding

It supports many application modes such as standby, island mode, and grid-parallel operation.

2) Synchronization & Load Sharing

One of the biggest advantages of the easYgen-3400 is its ability to synchronize multiple generators and share load.

Capabilities:

• Synchronization with utility grid
• Parallel operation of multiple generators
• Automatic load sharing (kW/kVAR)
• Up to complex distributed power systems

These features make it suitable for microgrid and distributed generation projects.

3) Built-in Protection Functions

The controller integrates full generator and grid protection:

• Over/under voltage
• Over/under frequency
• Reverse power
• Overcurrent & ground fault
• Loss of mains detection

This eliminates the need for separate protection relays.

4) Flexible I/O and Communication

The easYgen-3400 provides strong connectivity for SCADA and PLC integration.

Key communication features:

• CANopen / J1939 support
• Modbus RTU (RS-232/RS-485)
• Multiple analog and digital I/O
• CAN bus expansion modules

It can easily integrate into modern power management systems.
