DS3800XAIA1A is an Analog I/O Board manufactured and designed by General Electric. It is a part of the GE Speedtronic Mark IV Series. The system accomplishes dividing control functions among four microcomputers: three of which are identical control sections, and the fourth handles communications. Powerful online diagnostics pinpoint the faulty section, right down to the replaceable component.

DS3800XAIA1A Diagnostics

The Mark IV panel includes three types of diagnostics: power-up, on-line, and off-line. The power-on diagnostics include the following:

  1. Stall timer test.
  2. CPU instruction tests.
  3. PROM checksum tests.
  4. RAM data and addressing tests.
  5. Auxiliary processor self-tests

Because the tests include checks of the code and constants via checksums, passing these tests increases the likelihood that the processor hardware will function correctly. The on-line diagnostics are used to check the hardware for faults while the Panel is running. Specifically, those flaws that would go unnoticed due to redundancy are to be announced. To avoid interfering with normal turbine operation, diagnostics are performed as the lowest Priority task, running only when the turbine is otherwise idle.


  • Individual tests on the modules range from simple back-plane inspections to automatic wiring scans on wired back-planes and cables to full functional testing of power supplies.
  • The total hardware configuration will be functionally tested on the C communicator and RST controller modules.
  • A functional hardware test is performed on the fully assembled panel, during which all input signals are simulated and all output signals are validated. The tests and measurements are made from the customer interfaces for completeness.
  • The testing is fully programmed, providing a high level of assurance about the thoroughness and quality of the tests.
