Functional Description

DS3800DGRA is a Regulator Turbine Control Board designed and developed by GE. It is a part of Mark IV control system. It is responsible for regulating voltage levels and managing critical signals across the control system. It assists in processing feedback signals from the turbine and executing control commands to maintain optimal operating conditions.

Features

• Its primary function is to provide supportive regulation and stabilization for the main control processes. While it may not handle the core control logic directly, it plays a crucial supportive role by ensuring that voltages, signals, and communication pathways are accurately regulated and consistently available to the primary control boards.
• This auxiliary function is essential for maintaining system redundancy, improving signal accuracy, and protecting sensitive components from electrical irregularities. It helps maintain the balance between incoming sensor signals and outgoing control responses, which is critical in the high-speed, high-pressure environments of turbine operations.
• By offloading specific regulatory tasks from the main controller, the auxiliary regulator card allows the system to operate more efficiently, with greater fault tolerance and smoother performance. This layered approach to regulation is a hallmark of GE’s modular Mark IV system design, aimed at enhancing the reliability and lifespan of turbine control infrastructure.

FREQUENTLY ASKED QUESTIONS

What is DS3800DGRA?
It is a Regulator Turbine Control Board designed and developed by GE.

How does the system membrane switch operate?
The operator presses a pad on the membrane switch to arm a command. This is acknowledged by a flashing LED and an audible beep. The operator must then press the execute pad to carry out the command. Upon execution, the LED changes from flashing to steady on, confirming the command was accepted.

What happens if there is a delay between pressing arm and execute?
If more than 2 seconds pass after the arm command without pressing execute, the flashing LED will turn off, and the system will ignore the execute command. This is a built-in safety feature to prevent accidental operation.
