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: The board is equipped with a microprocessor that manages and processes data for optimal system performance.
• Amber Indicator LED: An amber LED is prominently positioned to be visible during normal processing. This LED serves as a status indicator for the board's operation.
• EEPROM Sockets: The board includes 8 sockets for electrically erasable programmable read-only memory (EEPROM) modules, allowing for easy updates and data storage.
• Jumpers: There are 21 jumpers on the board used for configuration and settings adjustments.

When the LED is off, it indicates that the board is functioning correctly and processing data as intended. No operator intervention is required at this time.
If the LED is illuminated, it signals that a fault has occurred and that power is present on the board. This condition suggests an issue that needs attention.

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.
