Question

Currently unsure of purpose of IN_3

DIS400 Activity Activity - Washing Machine Project Possible Solution Your team has been assigned the task of developing a timing logic diagram using the RS5000 PLC program to simulate the mechanical timer of a washing machine product. Design specifics and program sequence are as follows: 1. The machine is initialized (IN 1) ater valve is turned on until the float switch (IN_ 2) is engaged (assume one water level and temperature) 3. The wash cycle begins and runs for 12 minutes [T1] with the low speed motor agitator engaged (OUT 3). 4. A drain cycle (OUT 4) begins and last for two minutes [T2] while the drain pump is on (OUT_4) and high motor spin (OUT 5) with the S. Water valve is turned on to fill the tub for the first rinse cycle until the float switch (IN_2) is engaged 7. A drain cycle (OUT_4) begins and last for two minutes [T4] while the drain pump is on (OUT 4) and high motor spin (OUT 5) with the lid lock in lock position (OUT 6) st rinse cycle begins and runs for 4 minutes (T3) with the low speed motor agitator engaged (OUT.3) lid lock in lock position (OUT 6) 8. Water valve is turned on to fill the tub for the second rinse cycle until the float switch (IN 2) is engaged 9. The second rinse cycle begins and runs for 4 minutes (T5) with the low speed motor agitator engaged (OUT 3) 10. A drain cycle (OUT 4) begins and last for two minutes (T6] while the drain pump is on (OUT_4) and high motor spin (OUT 5) with the lid lock in lock position (OUT_6) 11. A spin dry cycle begins and runs for 6 minutes [T7) while the drain pump is on (OUT 4) and high motor spin (OUT 5) with the lid lock in lock position (OUT 6) 12. The system is stopped with brake (Out 7) and shut down by T7.DN. Use whatever knowledge that you have to date to build the PLC program to perform the required logic given the following inputs and outputs. Assume that a reset is required to reset any timers that you employ. IN1 OUT 2 Valve - OUT 3 Agitator IN3 OUT 5 Spin OUT 4 Pump IN 2 OUT 6 Lock OUT 7 Brealk

Answer 1

The purpose IN3 is to run the motor(agitator) with slow speed for 12 minutes when valve gets OFF(closed).
