- 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.

A single “start” button is used to turn on the power to the machine at the beginning of the day. In addition, there are two “stop” buttons located at two locations on the machine, either of which can be pressed to immediately turn off power to the machine. Let X1 = start button (normally open), X2 = stop button 1 (normally closed), X3 = stop button 2 (normally closed), and Y = power-to-machine. (a) Construct the truth table for this system.
