Sobering no?

Derrick, it is probable you are not licensed to help George.

The reality is that there are DIY PID installations almost daily and I'm sure that with your help George will end up with something.

George, Electrical engineering is my profession and I love it. Frustration is overcome by knowledge and understanding.

I still hope you buy a low energy power supply (like the one I sent you the link to) and play safely.

Think of it as playing with a mouse, if you do something wrong you might get a tiny scratch.

If you continue with this 230V endeavour, you're playing with a wild dog and if you do something wrong you're getting the teeth.

Be safe mate, I really want to learn how to make mead.

I just bought a two super hive.

And clearly your mead is effective. Derrick lost his grounding for a while there...Or did I mean parallel fault current return path???

(I'll be adding a conductor to my SSR heatsink !)

And with that, my dog has decided to give no more electrical advice to George (who didn't actually thank my dog for fixing his electrical drawing.. Not even a schmako) .

There are points in your 'neighbours' replies that are just bad practice when it comes to electrical design and I can't be bothered typing for my dog any more

 

[Zorco]

I have an English barleywine that will be bottled in about two weeks. I'd like to thank your dog for his correct drawing by sending him one?

It should be nice in a few months when he has recovered from his hangover.
PM me the address of your dog's kennel.

 

[Camo6]

Nice references Cosdog. They should be made a sticky in the DIY sub forum.

I have thoroughly enjoyed this thread, thanks for playing everyone.

If there's one thing we've learnt about electrical DIY on a beer forum it's this:

Ask your questions via PM. Hahaha!

Confirmation: Avatar checks out.

Interesting reading, in a much simplified circuit not being 100% familiar with the inkbird but in relation to the mentioned contactor. Other than the initial on/start up switch could you use the pid as the switch through a contactor to the element instead of the SSR.

 

[Camo6]

The PID cycles the element too frequently to employ a mechanical contactor. Premature failure of the contactor would be an issue I'd think.

 

[SCR29]

Thanks for speedy reply was just about to scratch/answer my own question after further researching my ponderings

Hi All,

Update change of plans, I how will be copying the http://www.theelectricbrewery.com/ design.

Just with small changes, needs to be 240v rating and along with three elements and three pumps also with a Voltage Regulator Dimmer to each pump so I can control the speed and on the the boiler element this will help to prevent boil over

The panel will be build in a PC case, My German friend will not be supervisioning, I will build it to spec than hand it over to a qualified electrician for testing.

 

[Zorco]

Good onya George. Let us know how you get on.

 

[Camo6]

You're probably all ready on to it George, but be sure to read the 240V section in the Electric Brewery Forum. Oh, and stop feeding Derrick that mead. It brings out the German in him...

 

[Bogan333]

Update

Getting close to building my electric brew panel.

It is only going to have 2200w elements, one in boiler one in the RIMS tube and the other in the HTL. one element will be on at any one time.

There will be three pumps along with 4000W 240V AC SCR Voltage Regulator Dimmer Electric Motor Speed Controller to each pump and one to the boiler element.


I have most parts now just waiting on these ones to come through the post

Three Green Pilot lights
Three Yellow Pilot lights
Two Supply Transformer
Six 3 Pin Plug Round Socket Power Adapter

It will be built in Full PC Case where the PC fans will come in to play, plus future upgrades by using the USB's to connect to a laptop

This is based on http://www.theelectricbrewery.com/

Update

This will be the biggest hurdle wire up this bad boy.
