Provide a summary of the operating procedure when using the proportional valve with schematic as a reference. To discover how the valve operates, read the reference material and experiment with the valve using a potentiometer and power supply wired into the valve circuit. Draw a wiring diagram and wire the circuit. Once the proportional valve is properly wired, apply a load to a steel specimen using the potentiometer to load and unload the specimen. Report absolute voltage values or voltage increments to raise, lower, and maintain constant position.
Report values to raise, lower, and maintain constant load.
DAS Open and Closed Loop Control of the Proportional Valve Write an engineering report about using the DAS rather than the potentiometer to control the valve. Compare the DAS and the potentiometer. Create a VI with a control knob on the front panel that will control the DAS analog voltage output, which will be used to command the proportional directional valve. Use a While Loop structure to continuously update the command voltage from the AO Update Channel function. Remember that you can test the program with random number generators.
