Functional Description

DS3800HUMA1A is a Universal Memory Board manufactured and designed by General Electric. It is a part of the Mark IV Series and is used in Speedtronic control systems. HUMA board is designed for easy installation in the drive. On one end of the board, there is a modular connector, and on the other, there are retention levers.

Features

• Reset Toggle Switch: The board is equipped with a reset toggle switch that allows the system to temporarily suspend processing without completely shutting down the power. This feature is particularly useful when there are intermittent issues, such as control signals becoming out of sequence or unreadable. By toggling the switch, a qualified technician can restore proper signal processing and resume system operation.
• Red Indicator LED: A red indicator LED provides visual feedback to alert operators of the system’s status. If there is an issue or fault with the memory board, the red LED will illuminate, helping technicians identify and troubleshoot problems quickly.
• Erasable Programmable Read-Only Memory (EPROM): The board includes several EPROM modules, which allow for the storage of critical control data. These modules can be erased and reprogrammed, providing flexibility in updating or modifying the system’s firmware as needed.
• Jumpers: The memory board also features ten jumpers that can be configured to adjust system settings or control parameters. These jumpers enable technicians to customize the behavior of the board to suit specific operational requirements or conditions.

Usage and Functionality

If the Universal Memory Board is experiencing issues such as intermittent problems with data processing or control signal misalignment, the reset toggle switch can be a quick solution. By toggling the switch, the board's processing is suspended temporarily, which can help resolve issues like signal out-of-sequence problems without requiring a full power down. Once the switch is moved, the system restarts, allowing the processing to resume in the correct sequence. However, since the toggle switch operation requires working inside the drive while it is powered on, it is critical that only a qualified technician performs this task to avoid potential hazards such as electric shock or burns.

Mark IV Historian

• The Historian is a client-server data archival system that collects, stores, and displays data from power islands and auxiliary processes. The product can be configured for just turbine-related data or for broader applications that include balance of plant process data, depending on the needs.
• The Historian is a sophisticated tool for investigating cause-effect relationships that combines high-resolution digital event data from the turbine controller with process analog data. The product combines OSI Software Inc.'s high-performance archive products with GE-developed data management functions for high-speed turbine event digital data.
• Advanced data compression techniques significantly reduce the amount of data storage media required. The Historian provides a menu of predefined database query forms for typical turbine calculations and analysis. The PI-ProcessBook and PI-DataLinkTM tools are versatile, allowing the operator to quickly generate custom trends and reports from archived process data.
