Functional Description

IC3600SVDD1D1B is a Vibration Calibrator Board manufactured by GE Fanuc. It is a part of Mark I and II control systems. It monitors and calibrates vibration signals, ensuring that the turbine machinery operates within safe vibration limits. By accurately processing vibration data, this board helps detect potential mechanical issues early, thus contributing to preventive maintenance and reducing unplanned downtime.

Vibration Protection System

• The vibration protection system is a critical safety component used in turbine and load equipment to monitor and control mechanical vibration levels. It primarily employs velocity-type sensors that are mounted on the turbine and associated load equipment to detect abnormal vibrations. In specific applications, such as load compressors—which often have a high stator-to-rotor mass ratio displacement-type sensors may be used instead, as they are more suitable for measuring relative movement between components in such configurations.
• The primary purpose of this system is equipment protection, not diagnostics. It is designed to respond to excessive vibration levels that may indicate mechanical problems such as imbalance, misalignment, bearing wear, or structural issues. When vibration exceeds predetermined safety thresholds, the system can trigger alarms or initiate shutdown procedures to prevent damage or catastrophic failure.
• Importantly, the system also includes self-monitoring capabilities to ensure the reliability of the vibration sensors themselves. Each sensor channel is continuously checked for potential failures such as ground faults, open circuits, or short circuits. If any of these faults occur, the system will activate an annunciator—a warning display or signal—to alert operators to the malfunction. This early detection allows for prompt corrective action, maintaining the integrity and safety of the vibration monitoring system.
• By providing real-time protection and sensor health monitoring, the vibration protection system plays a key role in preventive maintenance, reducing operational risks, and extending the life of critical machinery.
