sir thanks I really love your tutorials it is an instructor move tutorial. specially the lecture before programming is very nice. please can you include links for the power point. I am following the full playlist of learn plc hmi programming.
Quite surprised by the setup. In my opinion the low level switch should always interlock the pump and prevent it from running regardless if it's in auto or manual, otherwise you run the risk of the pump running dry which can damage it. This would mean manual simply allows you to pump out the tank when the upper limit hasn't been reached, ie when it's half full.
Sir you have connected low level switch in NC And high level switch in NO. But in ladder logic you have taken NO contact for low level switch and NC contact for high level switch. plz clarify this

Excellent demonstration
very useful video . keep making more ...

Very nice sir
Very nice !
Sir both level switch NC contact in Auto selection mode
Why there is need for M0 and M1 bit to make an OR logic to start the motor..Is X0 (Auto/manual contact) not enough for interlocking?? Please explain
