Description
🚀 Engineered for critical industrial applications, the Woodward 8200-209 is a robust ProTech 203 overspeed protection system. It reads three independent magnetic pickups, performs real-time speed calculations, and actuates relay outputs based on the collected results to safely shut down steam, gas, and hydro turbines during overspeed events.

Operating Procedures & Usage Methods
🛠️ Install the unit securely within a vibration-damped industrial panel environment, ensuring proper clearance around terminal blocks and easy accessibility for system diagnostics.
🔧 Connect active or passive magnetic pickup (MPU) sensors to the three independent speed-sensing channels, verifying proper shield grounding and tight screw connections to prevent signal interference.
📋 Configure trip setpoints, voting logic parameters, and acceleration thresholds using the internal keypads and digital front-panel display interface before system commissioning.
Power Sequencing Guidelines
🔌 Startup Sequence: Energize the high-voltage power source (88–132 VAC or 90–150 VDC) to initiate internal processor self-diagnostics across all three independent channels, verify zero fault flags, and confirm system readiness before turbine cranking.
🛑 Shutdown Sequence: Isolate the main power input feed only after the turbine rotor has completely spun down to a safe, stationary stop to prevent abnormal signal fluctuations during coast-down.
Product Usage Instructions
📖 The system utilizes a hardware-based two-out-of-three voting architecture, ensuring that a single sensor or internal channel failure will not result in a false turbine trip or compromise safety availability.
📖 Utilize the built-in frequency generator simulation feature to conduct routine online testing of individual modules safely while the prime mover remains fully operational.
Frequently Asked Questions
💡 Q: What is the input voltage range for the 8200-209 model? A: It operates on a high-voltage input range of 88 to 132 VAC or 90 to 150 VDC.
