After it has been clamped the piece is initially bent by a double-acting cylinder A and subsequently bent into the finished form by cylinder B. The sequence is initiated manually by a push button. The circuit must be so constructed that each time a start signal is given a full cycle is completed. Positional Sketch: 1.0 2,0 Electro-pneumatics Sequential Circuit Problem: Initial position all cylinder are retracted. Pressing the start pushbutton makes 5 cycles. After making 5 cycles lamp is energized for 3 secs. Cycle Operation: Cylinder A extend and hold the work piece. Cylinder B extend for 5 secs. Then retract. Cylinder A retract.arrow_forward
