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.
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
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.
