Functional Description

IS230SPROH2A is a Backup Protection Terminal Board manufactured and designed by General Electric. It is a part of the Mark VIe Control System. The terminal board serves as the host for a PPRO I/O pack within the Mark VIe system. Its primary function is to condition speed signal inputs for the PPRO, ensuring accurate and reliable performance. Additionally, the SPRO board is equipped with a pair of potential transformers (PTs) specifically designed for bus and generator voltage input, further enhancing its functionality in monitoring critical parameters within the system.

Features

• Adjacent to the pack connector, the board features a DC-37 pin connector, which serves as the interface for connecting a cable leading to a Mark VIe backup trip relay terminal board. This connection is instrumental in establishing a backup protection mechanism within the system, providing an additional layer of safety and reliability.
• One notable feature of the terminal board is its provision of 24 pluggable Euro-style box terminals. These terminals offer versatile connectivity options, allowing for easy and efficient wiring of various components and devices within the system.
• The integration of the terminal board with the I/O pack, along with the cabling into a trip relay board, forms the backup protection system in the Mark VIe system. While primary protection is typically provided by components such as PTUR (potential transformer unit for the generator), TTUR (potential transformer unit for the transformer), and a primary trip relay terminal board, the addition of the SPRO and PPRO combination with the trip relay board enhances system redundancy and reliability, ensuring continuous operation and safeguarding critical assets against potential faults or failures.

Installation

• Mounting Options: SPRO and a plastic insulator are mounted on a sheet metal carrier, which, in turn, mounts on a DIN-rail. Alternatively, the SPRO and insulator can mount on a sheet metal assembly directly bolted into a panel, providing flexibility in installation configurations.
• Wiring Procedures: Speed signals and PT inputs are wired directly to the terminal block using standard 18 AWG wires, ensuring secure connections and optimal signal transmission.
• Terminal Block Accessibility: The barrier terminal block is designed to be removable for convenient board replacement, facilitating maintenance and servicing tasks.
  Similarly, the Euro-Block type terminal block features removable terminals, allowing for easy board replacement without the need for complex disassembly procedures.
• PPRO I/O Pack Integration: The PPRO I/O pack seamlessly mounts directly on connector JA1 of the SPRO, ensuring a secure and reliable connection between the components.
• Backup Trip Terminal Connection: A DC-37 pin conductor cable is utilized to connect to connector JA3. The other end of the cable is then attached to the selected backup trip terminal board, completing the integration process.

Generator and Bus Voltage Sensors

• Configuration: Two single-phase potential transformers are employed, each with a secondary output supplying a nominal 115 V rms. These transformers serve as vital components for monitoring generator and bus voltages within the system.
• Loading Capacity: Each input of the potential transformers has a loading of less than 3 VA, ensuring minimal impact on the electrical system's overall performance and efficiency.
• Synch Voltage Range: The allowable voltage range for synchronization purposes is between 75 to 130 V rms, providing a wide operating range to accommodate various system conditions and requirements.
• Magnetic Isolation: Each PT input is magnetically isolated, enhancing safety and reliability by preventing potential electrical interference and ensuring proper isolation between the input and output circuits. The transformers feature a 1,500 V rms barrier for robust isolation.
• Cable Length and Gauge: The cable length for connecting the potential transformers can extend up to 1,000 ft., allowing for flexible installation options and accommodating installations in various environments. The recommended wiring gauge for this purpose is 18 AWG, ensuring sufficient current-carrying capacity and signal integrity over long distances.

Diagnostics

• Electronic ID parts are embedded components within the SPRO board and the backup trip relay terminal board that contain unique identification data for each module. Their primary role is to facilitate system diagnostics during the power initialization phase. When the system powers on, the PPRO (Primary Processor) or YPRO (Backup Processor) reads these IDs to verify that the correct hardware components are installed and configured. This ensures that only compatible components interact with one another, thus maintaining system integrity and preventing operational failures.
• During the power initialization process, the system performs a series of diagnostic checks. The PPRO or YPRO engages with the electronic ID parts on the SPRO and backup trip relay terminal boards to confirm their presence and functionality. If the IDs match the expected configuration, the system proceeds to normal operations. If any discrepancies are detected such as incorrect or incompatible hardware the system will prevent startup to avoid potential safety hazards or equipment damage. This initial check is vital for establishing a reliable operational environment.
• Diagnostics enhances system reliability and safety. By validating hardware configurations through electronic ID checks, the system can proactively identify and address potential issues before they escalate. This preventive approach not only minimizes the risk of unexpected downtime but also ensures that the system operates under optimal conditions. Enhanced diagnostics contribute to overall operational safety by confirming that all components are functioning correctly and are suitable for their intended roles, ultimately leading to improved performance and longevity of the system.
