4. Product Introduction & Supply Chain Strategy

The Woodward 8406-113 EGCP-3 package automates complex generator operations by governing fuel rack position, adjusting automatic voltage regulators (AVR), and opening/closing circuit breakers during synchronization routines. It replaces multiple standalone control relays, synchronizer modules, and load-sharing cross-tie networks with a unified digital control center.

Maintaining an uninstalled Woodward 8406-113 unit in New Surplus inventory is a vital risk-mitigation strategy for hospitals, data centers, and power utilities. An unexpected failure in a generator controller can prevent automatic emergency backup power transfer during utility outages. Stocking a genuine unused unit guarantees pristine keypad membranes, unaged power supply capacitors, and immediate drop-in replacement without requiring panel cutout modifications.

5. Installation & Configuration Guide

High Voltage & Mains Isolation Warning

Generator control installations involve lethal AC voltages (up to 480 VAC direct) and current transformer circuits. Always isolate main AC potential lines, short CT secondary circuits, and lock out engine starting power before mounting or servicing the controller.

1.System De-energization:Prerequisite.

Lock out main generator circuit breakers and disconnect 24 VDC control power and engine starting battery connections.

2.Panel Cutout Installation:Mechanical Mounting.

Mount the 8406-113 controller into the enclosure door cutout, securing all side mounting clamps firmly to ensure a tight dust seal.

3.Landing Power, PT, & CT Cables:Wiring Setup.

Terminate 24 VDC control power, 3-phase PT voltage sense lines, and 5A CT current input wires onto screw terminal blocks. Connect RS-485 load-share lines using twisted-shielded cable.

4.Parameter Setup & Sync Simulation:Commissioning.

Apply control power and configure PT/CT ratios, generator rating limits, and governor/AVR output bias ranges using the front panel keypad or Woodward Servlink software before initiating engine start.

6. Firmware/Software Versions & Upgrade Notes

  • Documentation Reference: Refer to Woodward Manual 26182 (or product spec 26180) for detailed wiring diagrams, LonWorks network architecture, and parameter tuning trees.
  • Network Load Sharing: Uses high-speed network communication between EGCP-3 units to balance kW and kVAR loads dynamically across multiple paralleled gensets.
  • Integrated Protection: Includes over/under voltage, over/under frequency, reverse power, overcurrent, and phase sequence protection functions directly in software.

7. Frequently Asked Questions (FAQ)

Q: Is this Woodward 8406-113 EGCP-3 controller genuinely new?

A: Yes, this item is a Brand New Surplus unit. It has never been installed in an active generator panel or wired to high-voltage PT/CT circuits, and is preserved in protective OEM packaging.

Q: What is the primary role of the EGCP-3 model 8406-113?

A: It provides full digital control for a single generator set operating either standby or in parallel with other generators and the main power grid.

Q: Can the 8406-113 control both the engine governor and the automatic voltage regulator (AVR)?

A: Yes, it features dedicated analog output channels to send bias signals to both speed governors (e.g., 4–20 mA, +/- 5 VDC) and voltage regulators to manage real (kW) and reactive (kVAR) load balance.

Q: What warranty accompanies this unit?

A: Every Woodward 8406-113 controller comes with a full 1-year replacement warranty and a certified quality inspection report prior to dispatch.
