Hi there Tycss,Yes, it can work in reverse. If you are in a hurry, check the instructions I gave to "Murray" about three years ago on how to modify the circuit to do what you just asked.I said back then I would write about these simple changes in the instructable, and I never did. Shame on me. I hope I don't forget this time.Cheers!
Anand7878,Check step 3 of this instructable. Circuit schematic diagram is shown right there.Rlarios
Great work HamedI2!I will really appreciate if you could share a link about those titanium sensors.Thanks, sir.
Dear Anand7878,Circuit diagram is shown in the instructable.Or, do you mean something else? Regardsrlarios
Hi Mark 62726,Thank you for your comments.You can have the CD4001 operate off 5V. You would need a 5V coil relay with contacts rated at least at 1A at 120Vac, and instead of the rectifier diodes and 7812 voltage regulator, you could use your 5V phone charger.rlarios
First clean flux residue with a cotton swab soaked in alcohol. Make sure board is clean on component side as well.Let me know if it still doesn't work so we continue debugging your control board.rlarios
DarshP5,Show me a picture of solder side of your PCB.rlarios
it depends on what you mean by that. Circuit operates on dc and I've seen some varying low voltage can be used and then rectified in order to be detected. There are other circuits out there that operate off ac power using relays, in case you're interested look them up on YouTube. rlarios
DarshP5,Wires wrapped around screws the way it's shown in pictures won't work properly. Crimp round terminals to wires ends and fasten terminals to either stainless steel or galvanized bolts using nuts and washers for a secured connection so they can be used as electrodes. I believe you can find these bolts, nuts and washers at home depot or your local hardware store.Let me know how this works. If you're still stuck with it at least we know electrodes won't be a problem. rlarios
See comments below.
Hi there DarshP5,Please provide pictures showing all electrodes in overhead tank which is the one that controls pump operation. rlarios
