6. The logic OR function A double-acting cylinder is used to transfer parts from a magazine. If either a push button or a foot pedal is operated, the cylinder is to ad- vance. Once the cylinder is fully advanced, it is to retract to the initial position. A 3/2-way roller lever valve is to be used to detect the full ex- tension of the cylinder. Draw the circuit diagram for the problem. Designate the valves and indicate the numbering system for the connec- tions (ports). The Problem Exercise Question OZ OS What happens to the cylinder, if the push button or pedal are pressed for a very short period and then immediately released? Describe the operation of the circuit. 1A 1S3
