SPECIFICATIONS
Part No.: PIMB base board
Manufacturer: General Electric
Country of Manufacture: United States of America (USA)
Product Type: Operator Interface Base Board
Availability: In Stock
Series: Mark IV
Functional Description
PIMB base board is an Operator Interface Base Board developed by GE. It is a part of the Mark IV control system. This board facilitates seamless communication between operators and the gas turbine system, ensuring efficient monitoring and control of turbine operations. Located on the front door of the Mark IV control panel, the PIMB Base Board acts as the foundation for the Operator Interface Module (PIMB).
Features
- Control Panel Integration: The Operator Interface Module (PIMB), supported by the base board, enables direct operator interaction with the turbine system. The module consists of a control insert and a printer housed in a roll-out drawer, allowing for quick data printing and operation logs.
- Advanced Membrane Switch Design: Equipped with an industrial-grade membrane switch that offers superior reliability compared to older dedicated switches. Operators can arm a command by pressing a pad on the membrane switch, which is confirmed by a flashing LED and an audible beep. The execute pad completes the command, turning the LED steady to indicate successful execution. A time-out feature automatically cancels the command if the "execute" pad is not pressed within two seconds.
- Auxiliary Display for Backup Monitoring: An auxiliary display in the upper-right corner of the control insert provides critical information when the CRT or communication computer is offline. Operators can monitor turbine conditions and control the load during maintenance or repairs.
- Dynamic CRT Display: The CRT (Cathode Ray Tube) adapts its display based on turbine status. During startup, it shows speed and starting conditions. During load, it prioritizes parameters like load, removing irrelevant startup information. Alarm information is displayed in the lower-left corner, showing the latest three alarms and their statuses. The bottom-right corner displays operator-selected parameters, providing real-time, customizable insights.
- Advanced Alarm Management: Separate control buttons for functions such as silence, acknowledge, clear, and review improve alarm handling. Unlike earlier systems that combined alarms, the Mark IV provides detailed messages, helping operators diagnose issues efficiently.
- Detailed System Monitoring: Provides access to values for logic, turbine-mounted switches, sensors, actuators, and relay statuses. Information is organized into menus and pages for quick selection and review.
- Soft Switches and Password Protection: Soft switches are software-defined, allowing dynamic labeling based on current operations. Adjustments to critical settings, like pre-selected load, require password authentication, enhancing system security.
- Simplified Adjustment Process: Operators can adjust settings using cursor controls and increment/decrement switches within predefined ranges. This process eliminates the need for manual tools like voltmeters or screwdrivers, simplifying system management.
