Functional Description
IS200TSVOH1BFC is a Servo Terminal Board developed by GE. It is a part of Mark VI control system. The Servo Terminal Board (TSVO) serves as a interface within the system, facilitating the operation of two electro-hydraulic servo valves responsible for actuating the steam/fuel valves. To gauge valve position accurately, it employs linear variable differential transformers (LVDT).
Features
- For seamless integration with the system, the component connects to the I/O processor (VSVO) via two cables. These cables utilize the J5 plug located on the front of the VSVO and the J3/4 connectors situated on the VME rack.
- In terms of signal distribution, offers Simplex signals through the JR1 connector. Additionally, it fans out TMR (Triple Modular Redundant) signals to the JR1, JS1, and JT1 connectors, ensuring redundancy and reliability in critical operations.
- It features plugs JD1 or JD2, designed to accommodate an external trip from the protection module, enhancing the system's capability to respond effectively to potential safety hazards or abnormal conditions.
Installation
- Installation of the Servo Terminal Board involves the direct wiring of sensors and servo valves to two I/O terminal blocks affixed to the board. These blocks are securely fastened with two screws each and offer 24 terminals capable of accommodating up to 12 AWG wiring. Adjacent to each terminal block, a shield termination strip is positioned, providing a connection to chassis ground for effective shielding.
- For additional functionality, external trip wiring is integrated into either JD1 or JD2, enhancing the system's responsiveness to safety concerns or abnormal conditions.
- Moreover, it supports Triple Modular Redundancy (TMR) configuration for servo outputs, allowing for enhanced reliability and fault tolerance. Each servo output can accommodate up to three coils, with the current for each coil being selectively determined via jumper settings using JP1-6. This configuration provides flexibility in adapting the system to diverse operational requirements while ensuring optimal performance and reliability.
Configuration
- In a simplex system configuration, configuring the Servo Terminal Board (TSVO) involves setting the correct coil current for Servo 1 and Servo 2 using designated jumpers. Specifically, jumper JP1 is employed to adjust the coil current for Servo 1, while jumper JP4 is utilized for Servo 2. The appropriate coil currents for each servo are outlined in the Servo Coil Ratings table, providing precise details for configuration.
- Alternatively, in a Triple Modular Redundancy (TMR) system setup, each servo output is capable of accommodating three coils. In such scenarios, configuring the coil current for each servo involves the selective adjustment of jumper settings. For Servo 1, coil currents are adjusted using jumpers JP1 through JP3, while for Servo 2, jumpers JP4 through JP6 are employed. This configuration flexibility ensures optimal adaptation to TMR system requirements, allowing for enhanced fault tolerance and reliability.
- Additionally, all other configuration adjustments for the servo board can be conveniently executed from the toolbox interface, providing users with comprehensive control over system parameters and ensuring seamless integration into diverse operational environments.
