{"Type": "Float Switch", "Working Principle": "A float switch consists of a float attached to an arm, which moves up and down based on the level. When the float rises or falls, it activates or deactivates the switch."n{"Type": "Vibrating Level Switch", "Working Principle": "This type of switch uses the vibration created by a magnet attached to the switch housing and a sensor to determine the level. When the liquid level changes, the vibration frequency changes accordingly, activating or deactivating the switch."n{"Type": "Ultrasonic Level Switch", "Working Principle": "These switches use ultrasonic waves to measure the level. The time it takes for the waves to travel from the sensor to the liquid surface and back is used to calculate the level."}

A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
