MET230L: Hydraulics and Pneumatics Lab Unit 4 Lab Assignment 2

This document presents a comprehensive solution to a hydraulics and pneumatics lab assignment (MET230L Unit 4 Lab 2) focusing on electro-pneumatic circuit design and simulation. The assignment covers the control of a double-acting cylinder using impulse directional control valves and relays, exploring the effects of momentary push buttons. It then introduces limit switches, pressure sensors, and optical proximity sensors in the control of pneumatic systems, demonstrating how these components can be used to automate cylinder extension and retraction. Various exercises involve building and simulating circuits, analyzing their behavior, and modifying parameters to achieve desired outcomes. The assignment also explores the use of spring-returned valves and single-acting cylinders, providing a practical understanding of pneumatic system design and control. Screenshots of the working simulated circuits are included. The document provides detailed explanations of the circuit's functionality, answers to specific questions raised in the assignment brief, and insights into the practical application of pneumatic components and control strategies. This assignment is a practical application of the concepts learned in the MET230L Hydraulics and Pneumatics course.
