Functional Description
IS200EBKPG1ADC is an Exciter Backplane Card developed by GE. It is a part of the EX2100 excitation system. Exciter Back Plane (EBKP) provides the physical and electrical framework for integrating control boards and facilitating seamless communication within the system architecture. It serves as a central hub for connecting and coordinating the operation of various components and subsystems.
Features
- Divided into three distinct sections, each dedicated to specific controllers and their associated boards. These sections, labeled M1, M2, and C, feature independent power supplies to ensure optimal performance and reliability. Sections M1 and M2 accommodate a comprehensive suite of control boards, including ACLA, DSPX, EISB, EMIO, and ESEL, while Section C houses DSPX, EISB, and EMIO boards.
- The upper part of the backplane comprises 24 DIN connectors, serving as integral components of the backplane infrastructure. These connectors facilitate the connection of control boards and other devices, enabling seamless communication and data exchange across the system.
- The lower part of the backplane features a diverse array of connectors, including 27 D-SUB connectors, three circular DIN connectors, three 12-pin power supply plugs and three fan power plugs. These connectors provide versatile connectivity options for interfacing with control boards, peripheral devices, power supplies, and cooling systems.
- Additionally, the backplane incorporates 30 testpoints, strategically positioned to enable convenient access for diagnostic and troubleshooting purposes. These test points serve as invaluable tools for monitoring signal integrity, voltage levels, and other critical parameters during system operation and maintenance.
- Labels on the connectors of the backplane correspond to the boards and devices to which the cables are connected, facilitating accurate and efficient cable routing and management. This labeling system streamlines installation, maintenance, and troubleshooting tasks, enhancing overall system reliability and serviceability.
- To ensure optimal thermal management, the backplane is equipped with two cooling fans located at the top. These fans facilitate airflow and heat dissipation within the control module, safeguarding against overheating and maintaining the reliability of critical system components.
Test points
- The Exciter Back Plane (EBKP) incorporates three groups of test points, each comprising seven individual test points. These groups are designated for controllers M1, M2, and C, respectively. The allocation of test points to specific controllers allows for targeted diagnostic monitoring and troubleshooting of each controller's functionality.
- To harness the diagnostic capabilities of the test points effectively, a toolbox is provided. This toolbox serves as a user-friendly interface for configuring and accessing the test points, enabling system operators and maintenance personnel to perform comprehensive diagnostic tests and analyses.
- The toolbox facilitates the configuration of testpoints for diagnostic purposes. Through the toolbox interface, users can select specific test points, activate monitoring functions, and customize diagnostic parameters according to the requirements of the diagnostic task at hand. This flexibility ensures that diagnostic testing can be tailored to suit specific system configurations and operational scenarios.
- Diagnostic Insights: By monitoring the test points, users can gain valuable insights into various aspects of controller performance, including signal integrity, voltage levels, communication protocols, and system response times. Differential test points, in particular, provide differential voltage measurements between two points, allowing for enhanced sensitivity to signal variations and anomalies.
- The availability of test points facilitates troubleshooting efforts by enabling the identification and isolation of potential issues within the control module. By monitoring test point readings and analyzing diagnostic data, system operators can pinpoint the root causes of operational issues, streamline troubleshooting workflows, and expedite the resolution of system faults or malfunctions.
- With test points allocated to each controller group, the EBKP enables comprehensive monitoring of system health across multiple operational domains. By regularly monitoring test point readings and trends, system operators can proactively identify emerging issues, implement corrective actions, and ensure the continued reliability and performance of the control module.
Board Replacement Procedures
- Begin by ensuring that the exciter system where the board is housed is completely de-energized. This step is crucial to prevent electrical shocks or damage during the replacement process.
- Unlock and open the exciter control cabinet door. Before touching any components, use appropriate testing tools to verify that no power is flowing through the circuits. This double-check ensures that it is safe to proceed.
- Ensure that all cables connected to the system are properly labeled with their corresponding connector names as marked on the board. This will make reconnection straightforward and prevent any confusion during reassembly.
- Disconnect all cables attached to the bottom part of the backplane. Unplug the fiber-optic cables from the EISB board. Disconnect the Ethernet cable from the ACLA (Active Communication Link Adapter) board. Ensure all cables are safely moved out of the way to facilitate the removal of the components.
- Remove all the control boards from the top section of the backplane. These boards include the ACLA and the filler plate, which are connected and will come out together. The DSPX (Digital Signal Processor) and the EISB (Excitation Interface) boards are similarly joined and will be removed as one unit.
Once all the control boards have been removed, unscrew the rack from its mountings by loosening the rack mounting screws. Gently pull the entire rack assembly out of the control cabinet.
- Position the new rack, which contains the replacement backplane, into the cabinet. Ensure it is aligned correctly, then secure it by inserting and tightening the mounting screws.
- Place all the control boards back into their respective slots on the backplane. Double-check that each board is in the correct position and tighten the screws to secure them firmly in place.
- Reattach all cables to their correct connectors on the backplane, ensuring they are connected to their corresponding labeled ports. Tighten each connection to avoid any loose contacts that could cause operational issues.
Reconnect the Ethernet cable to the ACLA board. Plug the fiber-optic cables back into the EISB board. Ensure the fan power plugs are also reconnected.
After confirming all connections are secure, close the exciter control cabinet door to complete the procedure. Test the system as required to ensure proper operation post-replacement.
