Hi All
Ive been asked to start this thread. Ive just copied from my thread and posted here. Mods if this is not on the correct forum please move it.
I enjoy DIY so here is my DIY Auto top-up.I dont have a DP yet but my sump is complete. My intentions is to have all the ducks in a row even before I start my DP which will also be DIY and this could only be next year as I dont get much time during the week or week-ends. I want to automate as far as possible as I enjoy all these little DIY gadgets etc.
Im still learning and dont know a hell of a lot, and this is where all you on MASA help and educate me in my venture of Marines.
So here is my DIY and please comment, as all the comments just help me.
:slayer: :slayer: :slayer:

Finally completed my DIY Relay control board and levels for Auto Fill and water change. There are 5 levels in all, 2 in the reservoir and 3 in the sump return to display chamber.
How it works.
When the water level in the sump is below the first level the level switch will close and start the pump the is a holding circuit wired in to keep the pump running till the water level reaches the 2nd level switch which will then open and shut down the pump. If these two levels fail, the top level will be activated and shut the whole system down. Thus avoiding flooding.
In the reservoir the top level is there just as a warning to fill the reservoir and the bottom one for system shut down.
Pump using is a 12vDC bilge pump for top-up and water change, which will be place in my top-up reservoir.
1]Pushbutton for manually pump start for water change.
2]Indication Lamp” Pump Manually running”
3]Indication Lamp” Top-up pump shut down”
4]Indication Lamp” Top-up pump running”
5]Indication Lamp” Reservoir pump shut down”
6]Indication Lamp” Fill reservoir”
7]12vDC Battery Charger
8]6A DP Circuit Breaker
9]Relays
10]Terminals to level switches
I will also be using this board to power up when there is a power failure

Wa Wa WEE wa. Now that is a work of art.
Bruce do us a favour and find a bowl to put some water into, and put us out of our misery. Foreplay is overated. I for one, refuse to wait until next year. Just do it.:)

Bruce - this is the correct thread... BUT, I do want to ask you if would mind elaborating on the PCB design?

If you would rather keep this secret, please let us know.

Please show us:
- what IC's/resistors/caps/transistors/transformers/relays/etc... used?
- do you perhaps have a schematic of the PCB?
- wiring diagram?
And brand of switches on the floats?

And perhaps costs of components?

Many thanks.
Jacques

Hi Jacques
All that is used is "finder relays type 44.52" a standard 220v/12vDC battery charger and the float switches are "Nylon type side mount hinge float type LSAZ-80-P1 and thats it. Im lucky as we work with components and I got them all for nothing the only item I bought was the termination block.The schematic is no problem and I will post it I just need to find a way to move it from AUTOCAD into a legiable format to be view or if that does not work I can always PM to who ever.If I may I will attach the company who can supply these componets.Please there is no secret 007 with me.:p

Please work it out. I had a thread running some time ago regarding alarms etc to warn me if sump etc is flooded because of the auto top up or if sumps runs dry. This looks as if it can definately be of help, preventing any flooding if something goes wrong.....

Bruce, no use posting the web page for the components. The last time I did a diy electronic board, I blew up my mom' hi fi speaker- Many moons ago- something you could use to measure the speed of sound going thru a speaker, needless to say, I never touched electronics after that
