You are to design a purely pneumatic circuit for the sequence given in Figure 4.2. The cylinders are controlled by 4/2-valves with double pilot activation. Each cylinder will have two 3/2-way limit valves x, and x₂, where x denotes a, b, c or d to detect the fully retracted and extended position for cylinders A, B, C or D respectively. Given that cylinder A is to extend with a slower adjustable speed and using a 4/2 valve as the manifold valve, (i) Write down the Boolean expressions for the manifolds and cylinder actions. (ii) Draw the circuit in the given template. (Note: Draw your pneumatic circuit in the template provided which has the symbols of the pneumatic cylinders and associated pneumatic valves. Add any additional components as needed. Additional template sheet is available if you need.)
