DS3800HLNC - Network Controller Module

SPECIFICATIONS

Part Number: DS3800HLNC
Manufacturer: General Electric
Country of Manufacture: United States (USA)
Series: Mark IV
Function: Network Controller Module

Functional Description

DS3800HLNC is a Network Controller Module developed by GE. It is a part of the Speedtronic Mark IV control system for gas turbines. The GE Network Control Board is engineered for efficient and straightforward installation within the drive. This board features a modular connector at one end and retention levers at the opposite end to ensure a secure and stable fit. Positioned between the retention levers is a 40-pin connector, which facilitates connections to other system components.

Features

• Microprocessor for Data Processing: The board is equipped with a high-performance microprocessor that handles data processing and network communication. Ensures real-time control by managing and interpreting system data for optimal turbine performance. Reduces latency and improves responsiveness in control operations.
• Amber Indicator LED for Status Monitoring: A prominently positioned amber LED provides a visual status indicator of the board’s operation.
  
  • LED OFF: Indicates that the board is functioning correctly and processing data normally. No intervention is needed.
  • LED ON: Signals that a fault has occurred while power is still present on the board, requiring operator attention.
  • Enables quick troubleshooting and minimizes system downtime.
• EEPROM Sockets for Data Storage and Updates: The board features 8 EEPROM (Electrically Erasable Programmable Read-Only Memory) sockets, allowing for easy firmware updates and configuration storage. Supports system customization and software enhancements without replacing the entire board. Stores critical control parameters, settings, and diagnostic data to ensure stable operation.
• Jumpers for Configuration and Settings Adjustments: Equipped with 21 configurable jumpers, allowing for fine-tuning and customization of board settings. Jumpers can be used to adjust operational parameters, enabling compatibility with different Mark IV system configurations. Facilitates easy reconfiguration for different turbine setups and operational requirements.

Troubleshooting Steps

If the amber LED is on, it is a signal that a fault may have occurred. The initial troubleshooting step is to check if the control signals have become misaligned or out of sequence, which can make them unreadable by the board. To address this:

• Verify Control Signals: Check the control signals to ensure they are correctly sequenced and properly connected.
• Restore Signals: Attempt to restore the control signals to their correct sequence and configuration.
• Monitor Processing Activity: After addressing the signals, observe the board to confirm that it resumes normal processing activity.
