Functional Description

IC3600SSVF1 is a Servo Valve Feedback Card developed by GE. It is a part of Mark I and II control system. SSVF card is instrumental in processing input signals from an LVDT, detecting peak values, amplifying and providing negative feedback signals, and monitoring signal thresholds. Its adjustments (FB Zero and FE SPAEJ) allow for fine-tuning to ensure precision in control and feedback processes. This card's capabilities make it an integral part of systems where accurate control and monitoring are paramount.

Features

• Input Signals from LVDT: The SSVF card receives its input signal(s) from an LVDT (Linear Variable Differential Transformer). This input signal contains information about the position or condition being monitored, such as the position of a valve or a related parameter.
• Peak Value Detection and Amplification: One of the core functions of the SSVF card is to detect the peak value of the input signal(s). This means it identifies the highest point or peak of the signal's waveform. After detection, the SSVF card amplifies this peak value, making it suitable for further control and feedback processes.
• Negative Feedback Signal: The amplified peak value is then used to generate a negative feedback signal. This feedback signal is crucial for controlling related systems or components, such as the SSVG (Servo Speed Valve Governor) regulator card. The negative feedback signal allows for precise and continuous control adjustments.
• Threshold-Based Monitoring: The SSVF card includes a monitoring system that checks the output signals of the peak detectors. If either of these signals falls below a predefined threshold, the output of OFBF (Output Feedback) becomes 1. This monitoring ensures that the system is operating within acceptable parameters, and any deviations trigger a response.
• Fuel Detector Circuit: In addition to peak value detection and feedback control, the SSVF card features a fuel detector circuit. This circuit is designed to provide an "off" signal (0) on the output fuel when the feedback signal reaches a predetermined threshold. This functionality is essential for maintaining fuel-related systems.

Adjustment Mechanisms

The SSVF card offers adjustment mechanisms to fine-tune its operation. Two primary adjustments are mentioned:

• FB Zero (R60): This adjustment likely relates to calibrating the feedback signal's zero position, ensuring that it accurately represents the baseline or starting point of the monitored parameter.
• FE SPAEJ (R62): Pertains to setting a specific operating range for the feedback signal, ensuring that it falls within the desired range for optimal control.
