Question
The sequence of operation to implement the process illustrated in Figure C2 is to be as follows: 2. 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 illing the tank. As the tank fills, the empty level sensor switch closes When the tank is full, the full levol sensor switch closes. . Solenoid A is de-energized. * Agitate motor starts automatically and runs for 3 min to mix the liquid. " When the agitate motor stops, solenoid B is cnergized 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 " SOLA Molor Full switch Emphy sensor wftch Stat's! otntrol station Figure C2 c) d) e) Construct an IO table. Construet a flowchart for the operation Construct the PLC ladder diagram based on your flowchart in b)Explanation / Answer
When inputs I/1, I/2 is closed and I/3 is open, first condition is satisfied. When I/3 is closed, second condition is satisfied. When I/3 is closed, third condition is satisfied. Relay is in latched state Relay is in unlatched state. PL2 will be on as the relay will be in unlatched state.
