Answer Posted / gururaajan
In first rung use NO contact of Pushbutton 1 and latch it
with 1st lamp NO contact.Then use NC contact of 2nd button
and in output side use 1st lamp.In second rung use NO
contact of 2nd button latched with NO contact of 2nd lamp
and in output side use 2nd lamp.

A flange is used for instrument connection for a system with a design temperature of 316C (600F) and a design pressure of 1000 kPa (145 psi). What is the class rating of the flange to be used for this application? Explain your answer
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.
