Develop an electro$-$pneumatic circuit, which automates the system of washing metal baskets by immersing it several times in a soap bath as shown in Figure $1$ and whose operation is described below:

a$.$ The operation is initiated by pressing a button. To do this, the cylinder must be in its final rear position.

b$.$ The cylinder will advance to its final front position. It then backs up to the intermediate position and moves back to the final front position. These movements follow each other until they are interrupted by a timer relay that is adjusted to $10s.$

c$.$ The cylinder then moves backward to its final rear position.

NOTE: In this exercise, $3$ position labels must be configured for the cylinder, one at the beginning, one in an intermediate position and one more in the final position.
