Product Overview

The 8440-1956 (model designation: easYgen-3400-1-P1) is an engine generator controller engineered by Woodward Inc. as part of the easYgen-3000 series for complex breaker applications. Housed in a durable metal frame, this controller features a 1 A CT input, Accuracy Class 0.5 precision, and a multi-lingual display supporting 15 languages including English, German, Spanish, French, and Chinese. It provides comprehensive generator voltage monitoring (delta or wye configurations) with configurable A through F alarm classes. Weighing approximately 1.85 kg (4 lbs), the unit manages setting power ranges from 0.5 to 99,999.9 kW/kvar in critical generator management systems.

Core Technical Advantages

  • Precision Power & Voltage Monitoring: Delivers Accuracy Class 0.5 measurement with configurable wye/delta voltage sensing to prevent earth faults.
  • Multi-Lingual User Interface: Built-in display support for 15 international languages simplifies field operation and diagnostics worldwide.
  • Flexible Alarm Management: Configurable alarm classes (A through F) allow precise threshold limit assignments and automated protective trip actions.

Industrial Applications

  • Genset Power Generation: Manages complex breaker operations and synchronization for diesel and gas engine generators.
  • Paralleling Control Systems: Coordinates load sharing and generator voltage/frequency matching across utility grids.
  • Emergency Standby Power: Controls automatic transfer switches and utility protection in critical infrastructure facilities.

Wiring & Installation

  • Panel Frame Inspection: Inspect metal housing for transit damage before mounting to prevent mechanical and frame grounding hazards.
  • Voltage Sensing Setup: Wire generator voltage sensing in wye (phase-neutral) configuration for isolated networks to ensure earth-fault protection.
  • CT & Contact Connections: Connect 1 A current transformer secondary loops and AgCdO relay contact outputs to specified control terminals.

Engineering Advantages

  • Compact P1 Form Factor: Optimized panel footprint compared to P2 series modules while providing core generator control functionality.
  • High-Durability Contacts: AgCdO contact materials deliver reliable switching endurance under continuous duty cycles.
  • Solid Metal Housing: Structural metal frame provides EMI shielding and physical rigidity in generator enclosure panels.

Technical FAQs

Q1: What CT input rating does the Woodward 8440-1956 controller require?
A1: The module is designed specifically for 1 A secondary current transformer (CT) input connections.

Q2: How should voltage monitoring be configured for isolated networks?
A2: Voltage monitoring must be configured as wye (phase-neutral) in isolated networks to prevent earth faults from causing false trip actions.

Q3: What power setting range is supported by the easYgen-3400-1-P1?
A3: The controller supports a wide setting range from 0.5 to 99,999.9 kW/kvar.
