Fanuc Corporation | GE FANUC RTD Conditioning Board Mark IV - DS3800NRTA
The DS3800NRTA is a printed circuit board (PCB) manufactured by General Electric (GE) for the Mark IV gas/steam turbine management system. Introduced by GE in 1982, the Mark IV replaced the earlier MKI and MKII Speedtronic systems from the 1960s and 1970s. It was the first Speedtronic system to use integrated platforms run by microprocessors, resulting in increased reliability and uptime and a decreased turbine outage rate compared to its predecessors.

The Mark IV system, introduced by GE in 1982, succeeded the earlier MKI and MKII Speedtronic systems from the 1960s and 1970s. The Mark IV was the first Speedtronic system to utilize integrated platforms controlled by microprocessors to manage turbine operations. This technological advancement resulted in increased reliability, higher uptime, and a notable reduction in turbine outage rates compared to its predecessors.Â
The DS3800NRTA is designed with factory-drilled holes in all four corners and is marked with alignment letters (A through J) on its top edge. It includes extractor clips in two corners, which serve as handles and leverage points for technicians to facilitate the removal of the board from tight spaces. The board is marked with the GE symbol and its identification number.Â

Maintenance Tips
-
Visual Inspection: Regularly check for visible signs of damage, such as burnt components, damaged traces, or any loose parts. Pay attention to the connectors and input/output areas.
-
Clean the Board: Use dry compressed air or an anti-static brush to remove any dust, debris, or particles. Avoid using liquid cleaners that may damage sensitive components or cause shorts.
-
Check Solder Joints: Inspect solder joints for cracks, cold solder, or corrosion, which could lead to unreliable or intermittent connections.
-
Verify RTD Input Signals: Test the RTD input signals to ensure they are within the specified range. Signal noise or deviations from the expected values can impact the accuracy of the conditioning process.
-
Power Supply Check: Ensure that the board is receiving a stable, correct power supply. Voltage fluctuations or incorrect power levels can negatively affect the board’s operation and damage components.
-
Run Diagnostics: Use diagnostic tools or software to monitor the board’s health, ensuring it is operating correctly and identifying any errors or faults in the system.
-
Monitor Temperature: Ensure the board operates within the recommended temperature range. Overheating can lead to premature failure of components and affect performance.
-
Inspect Connectors and Terminals: Check that all connectors and terminals are securely seated, free from corrosion, and in good condition to ensure proper signal transmission.
-
ESD Protection: Handle the board with electrostatic discharge (ESD) precautions, including wrist straps and anti-static mats, to protect it from electrostatic damage.
-
Secure Installation: Make sure the board is securely mounted in the system to prevent mechanical stress, vibrations, or disconnections that may affect its performance.
