Functional Description

DS3800DOAA1A1A is a Circuit Board developed by GE. It is part of the Mark IV control system. This board handles signal switching, output control, and interfacing with actuators or relays that drive turbine subsystems.

GE Mark IV Communicator Features

• The Communicator (C) is a key component within the GE Mark IV turbine control system, responsible for handling all non-critical turbine control, protection, and sequencing functions. While these functions are not essential for maintaining turbine operation after startup, they are vital for initiating the startup process. In short, the turbine cannot be started unless the Communicator is operating correctly, but it will continue running even if the Communicator encounters a failure during normal operation.
• In addition to its startup responsibilities, the Communicator (C) serves as the primary interface between the control system and external devices, including auxiliary panels, remote operator stations, and systems like DATATRONIC. Operator interactions are facilitated through industrial-grade membrane switches and a CRT display, allowing for effective command input and monitoring of turbine operations.
• The Communicator (C) maintains reliable, isolated communication with the three main turbine controllers—R, S, and T—via independent RS232 serial data links. This architecture reduces the risk of system-wide issues by minimizing interdependence between controllers. If one controller experiences a fault, the others remain largely unaffected thanks to this separation.
• To optimize system performance, non-critical sensor data (such as ambient temperature, auxiliary equipment status, etc.) is sent directly to the Communicator (C) instead of passing through the main controllers. Similarly, most operator interface signals are routed directly to (C), helping to offload processing from the R, S, and T controllers and maintain the integrity of critical control functions.

Frequently Asked Questions

What is DS3800DOAA1A1A?
It is a Circuit Board developed by GE under the Mark IV series.

How do the operators interact with Communicator?
Operators interact with the Communicator through industrial-grade membrane switches and a CRT display, which serve as the primary interface for commands and system monitoring.

What happens if the Communicator fails?
If the Communicator fails while the turbine is running, the turbine continues to operate. However, starting the turbine will not be possible until the Communicator is restored.
