Assignment 6:- Industrial Washing Machine

I-1 – Start / Power ON             I-2 – Stop          I-3 – High Level

I-4 – Door Open / Close input      I-5 – Low Level

Q-1 – Wash Cycle Indication     Q-2 – Rinse Cycle Indication

Q-3 – Spin Cycle Indication      Q-4 – Spin Action Indication

Q-5 – Motor running Clock-wise Indication

Q-6 – Motor running Anti-Clockwise Indication

Q-7 – Inlet Valve ON / OFF Indication

Q-8 – Drain Valve ON / OFF Indication

When Start button (I1) is pressed if Door (I4) of the Washing Machine is Closed, and Level of Water is Low (I5), Start Inlet Valve (Q7).

When level of Water reaches High Level (I3), Stop Inlet Valve (Q7) and

Start Washing Cycle i.e. make the Motor run Clock-wise (Q5) for 2 Seconds and then Anti-Clock-wise (Q6) for 2 Seconds.

Repeat this CW / ACW process till Q5 operates for 5 times (Use Counter for Counting).

When Q5 has operated for 5 times, Reset Washing Cycle. Drain the water till Low Level is reached.

Fill new Water till High Level is Reached again.

Now since Wash Cycle is Over, Start Rinse Cycle (Q2). i.e. make the Motor run Clock-wise (Q5) for 2 Seconds and

then Anti-Clock-wise (Q6) for 2 Seconds. Repeat this CW / ACW process till Q5 operates for 5 times (Use separate Counter for Counting).

When Q5 has operated for 5 times, Reset Rinse Cycle. Start Drain valve and keep it ON till Spin Cycle is Over.

Now since Wash & Rinse Cycles are over, Start Spin Cycle (Q3) & Spin Action (Q4), i.e. make the Motor run Clock-wise (Q5) for 2 Seconds

and then Anti-Clock-wise (Q6) for 2 Seconds.

Repeat this CW / ACW process till Q5 operates for 5 times (Use Counter for Counting).

When Q5 has operated for 5 times, Reset Spin Cycle.

Stop Drain valve when Low water level is reached and then stop the entire process.

During the process whenever I2 (STOP button) is pressed the entire process should stop.
