Problem:
Sheet metal is to be bended on a pneumatically actuated bending rig. 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.

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.
