IC3600SSVF1 is a Servo Valve Feedback Card developed by GE. It is a part of Mark I and II control systems. The 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.
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.
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.
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.
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.
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.
The SSVF card offers adjustment mechanisms to fine-tune its operation. Two primary adjustments are mentioned:

What type of input signals does the card receive, and from where?
The card receives input signals from an LVDT (Linear Variable Differential Transformer). These signals convey information about the position or condition being monitored, such as valve position or related parameters.
What is the significance of peak value detection and amplification in the card's operation?
Peak value detection is a core function of the SSVF card. It identifies the highest point or peak in the input signal's waveform. After detection, the card amplifies this peak value, preparing it for further control and feedback processes.
How does the SSVF card contribute to control systems through negative feedback signals?
It utilizes the amplified peak value to generate a negative feedback signal. This feedback signal is essential for controlling related systems or components, ensuring precision in control and continuous adjustments.
