Functional Description
IS230SPROH1A is an Emergency Protection Terminal Board developed by GE. It is a part of Mark VIe control system. The terminal board hosts a PPRO I/O pack, which acts as the interface for processing speed signal inputs for the PPRO. This integration enables the SPRO board to manage and control speed-related functions within the system, enhancing operational efficiency and safety.
Features
- Conditioning Speed Signal Inputs: As part of its role, the terminal board conditions speed signal inputs, ensuring that they are accurately processed and compatible with the requirements of the PPRO system. This conditioning process may involve filtering out noise, amplifying signals, or performing other necessary adjustments to optimize signal quality and reliability.
- Potential Transformers (PTs) for Voltage Input: The SPRO terminal board features a pair of potential transformers (PTs) dedicated to monitoring bus and generator voltage inputs. These transformers convert high-voltage signals into manageable levels suitable for input into the protective relay system. By monitoring voltage levels, the SPRO board contributes to the detection and mitigation of potential electrical faults or abnormalities.
- DC-37 Pin Connector for Backup Trip Relay Integration: Adjacent to the PPRO pack connector, the terminal board is equipped with a DC-37 pin connector. This connector interfaces with a cable leading to a Mark VIe backup trip relay terminal board. This integration enables the SPRO board to collaborate with the backup trip relay system, providing redundant protection and enhancing system reliability in critical scenarios.
Installation
- Mounting Options: The terminal board, along with a plastic insulator, is mounted on a sheet metal carrier, which, in turn, is attached to a DIN-rail. Alternatively, the SPRO and insulator can be mounted on a sheet metal assembly, directly bolted onto a panel. These mounting options provide flexibility to accommodate different installation configurations and requirements.
- Wiring Connections: Speed signals and potential transformer (PT) inputs are wired directly to the terminal block using typical #18 AWG wires. This wiring setup ensures secure and reliable connections between the input signals and the terminal board, facilitating proper functionality and signal transmission.
- Removable Terminal Blocks: The barrier terminal block, which accommodates wiring connections, is designed to be removable for board replacement. Similarly, the SPROH2A Euro-Block type terminal block features terminals that can be removed to facilitate board replacement or maintenance tasks. This modularity enhances ease of servicing and reduces downtime during replacement procedures.
- Mounting of PPRO I/O Pack: The I/O pack mounts directly onto connector JA1 of the board. This direct connection ensures seamless integration between the PPRO system and the SPRO terminal board, enabling efficient signal processing and control functions.
- Connection of Backup Trip Terminal Board: A DC-37 pin conductor cable plugs into connector JA3 of the terminal board. The other end of the cable is then attached to the selected backup trip terminal board. This connection establishes communication between the terminal board and the backup trip relay system, enabling coordinated emergency protection measures.
Diagnostics
- Initialization and Electronic ID Reading: During the power initialization phase, both the SPRO board and the backup trip relay terminal board undergo a diagnostic process. This process involves reading electronic ID parts embedded within these components. These electronic IDs serve as unique identifiers, containing essential information about the hardware configuration and specifications of each board.
- Utilization by PPRO: The electronic ID information obtained from the board and backup trip relay terminal board is utilized by the PPRO. Before commencing normal operation, the PPRO system verifies the validity of the hardware arrangement based on this information.
- Confirmation of Valid Hardware Arrangement: The electronic ID information serves as a reference for the PPRO system to confirm that the hardware arrangement is valid and matches the expected configuration. This confirmation step is crucial for ensuring compatibility, functionality, and safety within the system.
- Preventing Operation with Invalid Hardware: If the electronic ID information indicates an invalid or incompatible hardware arrangement, the PPRO system may prevent normal operation from proceeding. This precautionary measure helps mitigate the risk of potential hardware-related issues or malfunctions that could compromise system integrity or safety.
- Enhancing Reliability and Safety: By incorporating electronic ID reading into the diagnostic process, the system enhances reliability and safety by ensuring that only compatible and properly configured hardware components are utilized. This proactive approach minimizes the likelihood of errors, failures, or operational issues that could disrupt system functionality or pose risks to equipment and personnel.
