The operation is to be started using a push button (use the label START PB). Include a stop push button (use the label STOP PB) to stop the process at any time. (Use Memory ON circuit) 2. An acknowledgement signal (S1- Limit switch) is required when the piston is fully extended, to ensure that the work piece has been tipped onto the belt. 3. The extension should be slower than the retraction (use flow control valve) 4. The return stroke should be automatic. a. Design the Electro- Hydraulic Circuit with proper labeling.
