if we open the inlet of an air regulator ,how it will affect
the out put of regulator? (out put of regulator is using to
operate an on-off valve.it is an air to open valve,and valve
is in open position.my doubt is air regulator will hold the
valve in open or not,if there is no consumption or leak in
regulator out put side ,we only loose the input pressure.)

Answer Posted / karthikeyan

if you open the inlet of afr, valve ramains in open condition only, bcoz afr hold the output air pressure until u drain from regulator. and you are telling that while you are going to open the inlet of air regulator your valve is in open position, that means there should be air in outlet of regulator. bcoz your valve is air to open valve. if there is no air it should be in close condition.

The company where I am working, their is rosemount 5400 series radar type level transmitter, it is meant to show level of filled tank, but along with the level it is showing temperature also, so my question is how a onon-contact type radar type level transmitter can show temperature even if it does not have any contact with the fluid?

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.
