13) Write a program to implement the process illustrated in the figure below. The sequence of operation is to be as follows: • Normally open start and normally closed stop pushbuttons are used to start and stop the process. • When the start button is pressed, solenoid A energizes to start filling the tank. • As the tank fills, the empty level sensor switch closes. • When the tank is full, the full level sensor switch closes. • Solenoid A is de-energized. • The agitate motor starts automatically and runs for 3 min to mix the liquid. 15 • When the agitate motor stops, solenoid B is energized to empty the tank. • When the tank is completely empty, the empty sensor switch opens to de-energize solenoid B. • The start button is pressed to repeat the sequence.
