Class Activity Tank Level Control Situation: A process uses time to ensure a well blended and the process is started over. a miking tank with an agitator to mix liquid products for a specific period of mix. Once the proper time has elapsed, the mix is drained from the tank Task: Write a PLC program to perform the specific sequence and meet the time requirements as follows: re are two modes of operation (automatic and manual). If toggle switch S, is true, the automatic mode is being used. If S, is false, the operation is in manual mode. 1. The liquids are supplied to the mixing tank by opening the input valve "V". V, remains open until the tank is full. When the tank is full, the N.O. contact of the limit switch Lex s closecd providing a true signal. The program should then close the input valve V, and start the agitator motor to begin mixing the liquid ingredients 2. The agitator should operate for 5-minutes to provide a thorough mix of ingredients 3. After the mix cycle is complete, the agitator motor is turned off and the output valve "V"is opened to drain the tank. The tank is completely drained when the N.O. contacts of limit switch Lmin are closed. At this point, the output valve is closed and the cycle repeats itself as long as s is true. Manual Mode 1, when the N.. pushbutton switch "Si" is pressed continuously, input valve Vi is opened and its 2. When the N.O. pushbutton switch "S," is pressed continuousl 3. The agitator motor should run when V, and V are closed. panel lamp "H," is turned on. y, output valve V2 is opened and its panel lamp "H2" is turned on. 24V S, Auto Vs Fill H, Auto H2 Fill Agitator Empty Motor
