Woodward ProTech-GII Overspeed Protection Device: Ensuring Industrial Safety and Reliability

Ottawa, IL, December 2, 2024 – The Woodward ProTech-GII Overspeed Protection Device is a critical safeguard for industrial machinery, designed to prevent catastrophic overspeed events. This advanced system, detailed in Manual 26709 (Revision E, 5/2015), uses voted inputs from multiple sensors to detect and respond to overspeed conditions, ensuring immediate shutdown if necessary.

Robust Design and Performance

The ProTech-GII features a median voting algorithm that selects the most reliable signal from up to three modules. It can handle speeds up to 10,000 RPM and accelerations up to 10,000 RPM/s, making it ideal for high-performance applications. The device supports both energize-to-trip and de-energize-to-trip functionality, with the latter providing a safer fail-safe mode by tripping the prime mover upon power loss.

Easy Installation and Maintenance

Installation is straightforward, with clear guidance provided in the manual. The device supports both RS-232 and RS-485 communication protocols, with RS-485 requiring termination resistors (120 Ω) at each network end. Configuration is done via a user-friendly menu, accessible through soft buttons on the front panel. Password protection ensures secure access, and configuration changes are only possible when the module is in a "tripped" state, enhancing safety.

Advanced Monitoring and Communication

The ProTech-GII integrates seamlessly with plant networks using Modbus RTU protocol. It processes over 100 Modbus registers, providing comprehensive data on speed, acceleration, alarms, and trip events. A built-in diagnostic function tests communication links, ensuring reliable data transmission.

Comprehensive Logging and Diagnostics

The ProTech-GII logs all critical events, including overspeed, trips, and alarms, with time-stamped entries. The Overspeed/Acceleration Log records events with precision, capturing speed and acceleration at the point of detection. The Trip Log and Alarm Log provide detailed information on past events, aiding in troubleshooting and preventive maintenance. Logs can be viewed directly on the device or exported for analysis.

Commitment to Safety

Safety is a top priority. The ProTech-GII includes failed speed signal detection logic to prevent false trips during startup, and an optional Speed Fail Alarm alerts operators if the speed drops below a setpoint. The device is designed to operate in Class I, Division 2 environments, offering protection against explosion hazards. Personal protective equipment (PPE) recommendations ensure operator safety during installation and maintenance.

Conclusion

The Woodward ProTech-GII is a cutting-edge solution for overspeed protection, combining robust design, easy installation, advanced monitoring, and comprehensive logging. With its ability to handle extreme conditions and integrate seamlessly into modern industrial systems, the ProTech-GII ensures the highest levels of safety and reliability in critical applications.
