Functional Description

IS200EROCH1ADD is an Exciter Regulator Options Board developed by GE. It is a part of EX2100 control system. Exciter Regulator Options Card seamlessly operates in both simplex and redundant configurations. Installed in a single slot on the Exciter Regulator Backplane for simplex setups or the Exciter Regulator Redundant Backplane for redundant configurations, the EROC provides essential support for regulator functions, including excitation control, voltage regulation, and system monitoring. Its versatile design ensures efficient integration into the control system architecture, contributing to stability and reliability in excitation processes.

Replacement Procedures

• Ensure that the board rack containing the EROC is de-energized to guarantee a safe replacement process.
• Open the exciter control cabinet door and conduct tests on electrical circuits to confirm that power has been successfully turned off.
• Verify that all cables are properly labeled with the correct connector names as indicated on the EROC faceplate, facilitating a simplified reconnection process.
• Disconnect all cables from the EROC, including redundant and ISBus connections if applicable.
• Carefully remove the EROC from the rack following these steps:
  
  • a. Loosen the screws positioned at the top and bottom of the faceplate near the ejector tabs, ensuring not to remove the captive screws.
  • b. Unseat the EROC by raising the ejector tabs.
  • c. Using both hands, gently pull the EROC from the rack.
• It is designed for specific backplane slots; inserting it into the wrong slot can potentially damage the electronics.
• Slide the replacement EROC into the correct slot in the rack.
• Initiate the seating process by firmly pressing the top and bottom of the faceplate simultaneously with your thumbs.
• Complete the seating of the board in the slot by starting and then tightening the screws at the top and bottom of the faceplate. Ensure even tightening to guarantee the module is squarely seated.
• Reconnect all cables that were disconnected, ensuring accurate reattachment.
• Close the exciter control cabinet door to conclude the replacement procedure. This meticulous process ensures a safe and precise exchange of the EROC, maintaining the integrity and functionality of the exciter control system.

Application Data

• The Exciter Regulator Options Card, stands as a pivotal component within the system, embodying a double-slot height (6U) board equipped with distinctive features. Its physical design incorporates 96-pin P1 and P2 backplane connectors, ensuring a robust and secure connection within the system architecture. Notably, the absence of fuses or testpoints streamlines its design, emphasizing reliability and simplicity in operation. A singular green LED serves as a power indicator, providing a visual cue of the operational status when power is applied.
• In terms of power requirements, the EROC efficiently operates within specified parameters. It relies on a Digital +5.0 V dc power supply with a tolerance of ±5%, ensuring stability, and a maximum power consumption of 5 Watts. Additionally, for analog components, the EROC accepts ±15 V dc power inputs with a tolerance of ±10%, consuming a maximum of 15 Watts. This dual power supply configuration reflects the EROC's adaptability to different power sources, optimizing its performance and responsiveness within the broader system.

Frequently Asked Questions

What is IS200EROCH1ADD?
It is an Exciter Regulator Options Board developed by GE under the EX2100 series.

What keypad connectivity options does it feature?
It is equipped with a keypad connector on its faceplate and another on the backplane, accommodating both ERBP simplex and ERRB redundant configurations. This dual-connector setup offers flexibility in keypad integration within the EX2100 regulator control system.

Can multiple keypads be simultaneously connected?
No, only one keypad can be connected at a time. It is designed to ensure optimal system performance by allowing a single keypad connection, preventing potential conflicts or data discrepancies.

What type of keypads are supported by the connectors?
The keypad connectors are designed to support bezel-mounted keypads. This ensures compatibility with a specific keypad design, contributing to a cohesive and streamlined appearance within the control system.

Why are there two keypad connector locations?
The two keypad connector locations serve to support mounting variations of the EX2100 regulator control system. This design feature accommodates different configurations of control cabinets, enhancing adaptability to diverse system setups.

How does the EROC communicate with the keypad connectors?
It communicates with the keypad connectors using RS-232C, a widely used serial communication protocol. This ensures reliable and standardized data transmission between the EROC and the connected keypad. The baud rate for this communication ranges from 1200 to 38.4 K, allowing for flexibility in data transfer speeds.
