Submersible Pump Wiring

[bankruatsteve]

Just a thought...  When you get the pump running on FROG control, try taking the L,N output to the pump from your "smart box" to the L,N in the FROG control (replacing the mains incomer).  Forget about the capacitor in the smart box.

Have you "buzzed out" the pump wiring?

 

The pump wiring went from the pump thru the fence to my Intelligent pump box. The pump wires ar attached under the water pipe as in pic. 

I cut the wire and installed the origional FROG controller at the top of the bore, as in pic.

Don't see the incoming mains but I guess it's there somewhere, yah?

It's the yellow conduit on the left. 

The pump cable tied to 2 NYY cables inside flexible conduit go to the big hole in the middle. The 2 NYY cables are from the pressure switch and water tap.

The conduit on the right is from the contacts from the float in the water tank out the back.

So the thought was the pump would stop and start from the pressure switch or tank float switch.

Seemed simple at the time. ????

Found the problem. The wiring of the Frog control box wasn't as per the circuit. One side of the on/off switch neutral wire was missing. No neutral.

All I can think is the bore guy took the wire out and wired the pump straight into the main incoming neutral and not thru the switch.

Now if I'd only taken a pic before I started. Usually do. ????

Now back to getting the new pump controller going.

At least you know that the pump still works.

 

"Should" be easy now (famous last words).

 

I assume you are using the same capacitor in the new controller as in the Frog?

Yes using the same value.

So now I re-learnt induction motors a bit more twas easy.

Also the Intelligent control box wiring diagram is wrong. (I think you may have guessed that Crossy). The link shown is missing the capacitor symbol.

Now that works as well.

Just gotta hook up the tank float control and pressure sence control and put in auto.

Just to show you I used to know something about motors, here is a pic of one of our (everybody) first year Engineering projects, about 60 years ago. ???? Where's your?

I did 'lectronics, 2nd year project, medium wave superhet radio.

 

First thing everyone did when it was complete? Convert it into a transmitter of course

 

[Crossy]

Although the first year was metal bashing!

 

 

Now which of this dicey looking lot was Crossy?

My wife and my step-son got it in one.

 

Step grand-daughter was waaaayyy out!

Seem not to be getting notifications.

I think you ate in the back row. Looks like there were a couple of ladies in the class. Progressive.

555 no ladies, the first female apprentice was the next year, Nicky Cox.

 

Back row second from the right, I had hair then (I was 16).

Well everything works like it should. Tank fills up, tap outputs water as well.

Pump pressure builds up to 24 psi.

Some idiot installed the RCBO the wrong way. They don't like testing that way. Probably wear my glasses next time and not do that again.

Thanks all for help. ????
