Functional Description

IC3600STFA1 is an overspeed test board developed by GE. It is a part of Mark I and II control system. The component within control systems, specifically designed for testing and ensuring the safety of the system by monitoring and controlling overspeed conditions. Its functions encompass gain adjustment, customizability through jumpers, digital setpoint inputs, and the ability to modulate acceleration to ensure safe and controlled operation. The board's features are critical for maintaining safety and efficiency in various industrial and machinery control applications.

Features

• Overspeed Trip System: Essential for ensuring the safe operation of machinery or systems. This system consists of two separate sensing circuits, providing increased reliability in detecting and responding to overspeed conditions.
• Overspeed Test Pushbutton: The board features an overspeed test pushbutton, which serves as a manual control to test the system's response to overspeed conditions. When activated, it feeds a negative bias into SJ, which subsequently increases NVCE (Negative Voltage Control Error). This allows operators to verify the system's ability to respond to overspeed conditions effectively.
• Jumper Settings for Transfer Function: Jumpers can be configured between pin CC and CE to set the desired transfer function. These settings are important for customizing the card's response to specific input signals.
• Gain Adjustment with Potentiometer RI 14: Potentiometer RI 14 plays a vital role in the card's operation. It provides a gain adjustment mechanism, allowing operators to fine-tune the card's response to ensure precise control in overspeed conditions.
• Digital Setpoint (DSP) Inputs: The board offers inputs SPA and SPB for the digital setpoint (DSP) signal. These inputs are instrumental in setting and adjusting the desired operating parameters to effectively manage overspeed conditions.
• Differentiator Circuit for Acceleration Control: The card includes a differentiator circuit that monitors the speed feedback signal N and modulates VCE (Voltage Control Error) to limit the accelerations of the turbine or the controlled machinery. When VCE is under acceleration control, the output AC is set to "1."
• Halving Acceleration Control Rate with HR and ACOM: By connecting HR to ACOM, operators can halve the acceleration control rate. This adjustment allows for precise control over the rate at which the system responds to acceleration changes, enhancing safety and control in overspeed situations.
