DS215GGIAG1BZZ01B is an Exciter Voltage Regulator Module manufactured and designed by General Electric as part of the EX2000 Series used in GE Excitation Gas Turbine Control Systems. The firmware that powers this board is a testament to GE's commitment to innovation, ensuring that the board effectively translates digital instructions into tangible actions, enabling efficient control, monitoring, and coordination of processes. It facilitates the flow of information, commands, and data across the system, acting as a bridge between various subsystems and components. Through this role, the board enables the system to maintain precise regulation, enhance stability, and optimize performance, all while adhering to the highest standards of safety and reliability.


  • It is pre-drilled at each corner for mounting. The board's surface is covered in connectors, including two small terminal strips with three connections each, ten vertical pin cable connectors with varying pin counts, six vertical header connectors, and several stab-on connectors.
  • Other board components include five fuses in fuse holder clips, a potentiometer, and jumper switches, as well as over four dozen resistor network arrays. The TP test points on the board are primarily located on the right board edge, where users can connect test clips to check voltage levels.
  • The main processor and LAN Communication Card are included in an EX2000 system. It also has a programmer module (keypad and display) and communication inputs to the exciter that are both isolated and non-isolated.
  • This card also includes an automatic voltage regulator, field voltage regulator, field current limit regulator, volts/hertz limit regulator, reactive current compensation, under excitation limit regulator, built-in diagnostic display panels, and an operator control simulator.
  • The separate control simulator is a sophisticated system program that models the field and generator behavior and is located within the core software. In the microprocessor application card, signals representing the field and generator feedback are simulated and fed to the transducing algorithms in place of the real feedback.


  • Communication interfaces: RS232 Modbus, ARCnet, and Ethernet
  • Redundant and modular backups for communications and other systems
  • Mounting: Factory-drilled corners for easy mounting
  • Connectors: Multiple connectors on the surface, including:
  • Two small terminal strips with three connections each
  • Ten vertical pin cable connectors with varying pin numbers
  • Six vertical header connectors and several stab-on connectors
  • Additional Components on the Board: Five fuses in fuse holder clips, four dozen resistor network arrays, LED indicators, a potentiometer, and jumper switches
  • TP: Test Points primarily located on the right board edge for voltage level checks
  • Other components: inductor coil, heat sinks, three relays, transistors, resistors, diodes, and capacitors

What are self-test diagnostics in the EX2000 exciter software?

Self-test diagnostics are built-in features within the EX2000 exciter software that allow the system to automatically check its own functionality and identify potential faults or issues.

How does the self-test diagnostic system work?

The self-test diagnostic system within the EX2000 exciter software conducts automated tests on various system components. If a fault is detected, the system generates fault codes that indicate the nature of the issue.

What is the purpose of displaying fault codes on both the programmer's display and the LDCC board's LEDs?

The dual display of fault codes provides redundancy and backup in case one display method becomes unreadable or unavailable. It ensures that operators can quickly identify faults and initiate troubleshooting, even in challenging situations.
