Description
- The WOODWARD 8406-115 is a comprehensive Engine Generator Control Package (EGCP-2) designed for use with automatic transfer switches or parallel power generation systems. This microprocessor-based control unit combines generator protection, engine management, and automatic sequencing into a single, rugged package. Engineered for complex industrial power networks, the 8406-115 handles automatic synchronizing, dead-bus closing, real (kW) and reactive (kVAR) load sharing, and generator peak shaving. It provides high-reliability control for diesel or gas-propelled generator sets, ensuring stable utility paralleling and emergency backup operations.

Comparison with Similar Models
The 8406-115 is distinguished within the EGCP-2 series primarily by its voltage configuration and software application profile. While the 8406-114 is tailored for simpler, isolated multi-generator networks, the 8406-115 is fully equipped with the utility-paralleling algorithms required for peak shaving and base-load operation alongside a commercial power grid. Compared to newer digital control series like the Easygen-3000, the 8406-115 relies on an established, deterministic menu structure that does not require complex PC configuration software for standard maintenance and setpoint adjustments.
Operation Tips
- Phase Rotation Matching: Before activating the automatic synchronizer, double-check that the bus and generator phase rotations are identical (e.g., A-B-C) to prevent catastrophic out-of-phase paralleling.
- CT Orientation: Ensure that the current transformers (CTs) are installed in the correct orientation (facing the load) and that the CT ratio is accurately keyed into the system configuration menu.
- Modbus Communication: When integrating this unit into a plant SCADA system via RS-485, ensure a 120 Ω terminating resistor is placed at the end of the data link to avoid signal corruption.
- Firmware Backup: Always record all customized setpoints and calibration values manually or via ServLink before updating or replacing the control module to prevent the loss of site-specific tuning parameters.
