Main Features and Advantages
Integrated Engine-Generator Control Platform: The WOODWARD 8406-113 consolidates multiple control functions—engine start/stop sequencing, automatic synchronizing, digital speed governing, voltage regulation interface, and load sharing—into a single panel-mounted chassis. This integration eliminates the wiring complexity, panel space, and coordination challenges associated with separate synchronizer, governor, and load-share modules.
High-Precision Digital Load Sharing: The WOODWOOD 8406-113 employs high-speed network communication to balance both real (kW) and reactive (kVAR) loads across multiple paralleled generator sets without the drift and calibration issues inherent in analog droop systems. Up to sixteen generators can participate in load sharing, with support for isochronous, droop, and base-load operating modes .
Comprehensive Generator Protection: Integrated protective functions within the WOODWARD 8406-113 include over/under voltage, over/under frequency, reverse power, overcurrent, and phase sequence monitoring, with configurable alarm and shutdown thresholds . These protections operate independently of the engine governor and voltage regulator, providing redundant safety layers for critical power assets.
Dual Display Operator Interface: The WOODWARD 8406-113 features two backlit LCD screens that simultaneously present eight lines of operational data, with nine dedicated status menus enabling rapid navigation to specific parameter groups . The membrane keypad permits local configuration and tuning, while ServLink connectivity provides access to advanced parameters through Watch Window software.
