Woodward 8406-113| LS (Load Sharing) Model
EGCP-3 Engine Generator Control Package - Model 8406-113 (LS)
Description
The EGCP-3 Engine Generator Control Package, model 8406-113 (LS), is designed for load sharing and control of generator sets in parallel operation. It provides comprehensive monitoring and control functions to ensure reliable and efficient power generation. The system supports both voltage and power factor (VAR/PF) control, with features that enhance operational flexibility and safety.
Features
- Load Sharing: Automatically adjusts the generator's output to maintain a balanced load distribution across multiple generators.
- VAR/PF Control: Maintains constant reactive power or power factor by adjusting the generator voltage.
- Analog and Digital Inputs/Outputs: Supports various input/output configurations for flexible integration into different systems.
- Modbus Communication: Facilitates data exchange and remote monitoring via Modbus protocol.
- Battery Charging Protection: Prevents damage to the control system during battery disconnection.
- Safety Alarms and Shutdowns: Includes multiple alarms and shutdown mechanisms to protect against overfrequency, underfrequency, speed mismatches, and other critical conditions.
- Start Sequencing: Configurable start attempts, crank delay, and idle speed settings for reliable engine startup.
