I've briefly read through this but it sounded liked it worked until you put in the alarm contact. Try bypassing the alarm contact with a jumper and see how that goes.

The DIM Led sounds like something is floating, perhaps a 5.6k pull down resistor across the + and - terminals of the relay would fix this. I am guessing that breaking the + side with the alarm contact has something to do with this. Doesn't explain where the potential is coming from though.

If anything, just disconnect the PID completely and use a wall transformer power supply to trigger the SSR. If the element turns on, the problem is on the DC side.

Attach the PID back but straight to the SSR control line, if it has a manual function use that to turn it on. If that works take one more step closer to the final wiring.

good luck
 
I am starting to get the feeling that a problem does exist within the PID. I will talk with Auber on Monday and I hope to get clarification. If there is a problem I just want to make sure that the problem doesn't exist in something that will just damage the new PID as well. Again thanks for all the continued help.

With the wall transformer the ssr triggered and powered the element outlet.

Did this and no go. This time there was no ouput power reading from the multi-meter coming from the PID to the SSR

Not familiar with a 5.6k pull down resistor is. This would be used on which side of the SSR? The power side coming from the PID or the output side coming out of the SSR to the element outlet?

I completely elemented the breaking of the + with the alarm. Both in the wiring and the setting in the PID. Same problems still exist.
 
I just got my PID back from Auber...it had a fried resistor...not sure were it got fried but Auber thinks it would of have to been exposed to the 110v on the system...perhaps I made a mistake when wiring for the alarm, can't say...they repaired it and the PID now works...the problem still exists with the switch for the element where the light was very dim and not switching the element...so I wired the PID without the switch for now...I got a brew on it this last weekend and everything went well...I just lower the SV to well below PV as a means of keeping the element from coming on if I am switching hoses or the like...I'll have to tackle the switch at some point but the system is working and functional.

I would like to comment on the customer service from Auber...they were very quick to respond to my questions and went above and beyond in helping me correct the problem. My PID was 1 month out of warranty but they fixed it anyway and turned it around in less than 2 days...great company.
 
POWER!

These are the cords I built for power in and element power. 12AWG stranded, protected with PET weave, heat shrunk ends, and 20 amp plugs.

sexy....
I agree. Any chance of getting a parts list of connectors, receptacles and the mesh wrap you used?
One tip on the mesh wrap though. After taping the wrap on, push it up over itself and inside the connector and cinch with a small sip tie. Hides the tape and looks super clean. We use a similar type here for the cables for our machines. We only have black, but I like the white you have and those connectors. Very Storm Trooper:D
 
Dude I like your designs. I like the fact that you set yourself up to use RIMS or HERMS. The one thing i don't really understand is only having one PID. When you brew with RIMS, wouldn't you need 2 PID's? One to control the MLT and the other to control the RIMS heat element?
 
The MLT does not have an element in it. Only the BK and the RIMS have an element, and only one can be run at any given time.

In other news, I am working on the pump setup and have ordered my first kettle. So I should have some updates soon.
 
oops I meant BK. I suppose the kettle maintains enough heat while you are stepping that another PID really isn't necessary.

Cool man, keep us updated. Does the first kettle (aka 1/4 bbl) come with beer in it? haha
 
Yeah, when I use the RIMS I will not use the HERMS coil so the BK element will be off. You would need more power to run two elements at once (and thereby need two PIDs).

I am actually going with 24qt stainless stock pots now. I will update everything soon. I love the kegs, but am going to go with stock pots to try something different.
 
Glad to see I'm not the only one who can't leave well enough alone :mug:
 
I have still been looking at putting together a rig like this but we bought a house last year and the new place is all 120V 15A so it puts a damper on my electric brewery plans unless I do a big, expensive electrical upgrade (subpanel has to be upgraded, need a new run from main box to subpanel, new runs to appropriate outlets, etc.).

So now I am thinking about something similar only with propane, HERMS, and a couple of solenoids. Although I suppose I could still do something similar and limit my batch sizes to maybe 2.5-3 gallons, especially if I use e.g. a cooler MLT design for one of the vessels.
 
Meh, the rubber kegs are easy to get. I just want to do a build with actual kettles. They are lighter and I want the less rounded bottom. I am also going to try some insulation ideas. Just something different.

You could do this build with a flat bottom kettle and suppliment the heating power with your stove. I think that is a cool idea...

It's a cool idea until I forget to close a valve and get wort spraying all over the kitchen. At least when I do it outside my wife won't kill me.
 
Just wanted to say thanks for this thread, and R.I.M.S. 4 dummies. Got my controller up and running. Thanks for the inspiration!

Your control box def inspired my box. I don't have pics, but I did use love controllers. Mine controls HLT and MLT. Very simple.

Question: Did you ever use the rubber kegs?

I just drilled the top off for my HLT, element hole, thermowell hole, and valve hole, but then realized while I was trying to install my element that the 1/4" rubber puts a big damper on the short element thread and also, how did (would) you ground?

I was thinking of grinding down a hole through the rubber deep enough against the SS to stick a ground wire terminal between the rubber and metal. OR I was going to chip and chisel away enough of the rubber around the hole to press the metal electrical/element box against the metal side of the keg. I would prefer to do the later, considering I built a nice small element receptacle before acquiring a rubber keg.
 
Yes, I did use rubber kegs in the SIMPLE build. I used a hole saw to cut away just the rubber around my holes so I was left with a clean stainless surface for mounting sensors and elements to.

cheers
 
I built a small electrical box around the element for easy grounding. On a normal keg, it would attach right to the side. After thinking about it for a couple days, i took a dremel and reinforced cutting wheel and cut a 4" x 4" square out of the rubber around the hole I drilled for the element exposing the metal. Thus being able to easily ground the steel.

Does the silicone o ring go on the inside of the tank or the outside?
 
I love the thread, really informational!

I notice that you are only using a single RTD for the system. Have you had any issues with keeping the mash at the proper temp when you recirculate it?

From what I've been reading, it seems that you'd want to use two RTD elements to make sure your temps are as accurate as can be. One RTD inside the HLT/BK for measuring the temp of strike water and another on the output of the HERMS coil to make sure your mash stays at the right temp during recirculation.

Is a second RTD really necessary, if so, how would change the wiring to switch between the two RTD elements while brewing.

Thanks
 
You can't switch between 2 sensors because the switch will alter the current in the wire for an accurate reading. However you could get 2 probes from auber with the twist lock configuration and just switch the the to the sensor you wish to get a reading from and have a switch on the box from bk to rims or herms to tell it which element to control
 
It would appear I can no longer edit entries???

Anyway, I am finally going to wrap up my brewery and thought I would update the thread.
Here is the MLT (left) and BK (right)

They are each 24 qt. stainless from Bayou Classics. All connections are silver soldered.

Here is a shot of the inside of the MLT, it has a Jaybird Falsie supported by a thermoplastic tubing ring, a snap lock return hose, and a thermowell for receiving my PID's RTD probe.
CIMG6948.jpg


Here is a closer shot of the probe; it sits just above the false bottom.
CIMG6950.jpg


The boil kettle includes a tangential return, bottom drain, heating element, and thermowell. Here is a shot of the heating element.
CIMG6954.jpg


The outside f the kettle has a metal receptical box silver soldered in place over the element nut.

The tangential return is just a swagelok and a stainless elbow:

Anyway, All that is left now is to build my stand for it and finish the pump box. I have all the parts now, so I just need to find some time. I really want to brew with a friend just after the holidays, so I am pushing to finish soon!
 
Great to hear from an inspiration!!! :mug:

For those unaware jkarp is the mastermind of 120VAC for e-brewing.

..........................................................
The PID uses an RTD that I will be able to move around. Each vessel will have a thermowell in
the sightglass base. Each sight glass will be assembled like this:

with one of these

threaded into the connection instead of the plug.

I will also have a thermowell for monitoring liquid temp through the heat exchangers:
Brewers Hardware, LLC. :: Warning


The thermowells as well as a ton of other stuff are all coming from HBT member Derrin ala


So I will be able to check temps wherever I want. Or at least that is the idea. I will also have
two analog thermos sticking through the lids down into the mash/boil.

Can you please provide more detail on the sight glass and fittings?
 
Long time lurker, first time poster.

This piqued my interest, as it relates to my upcoming electric build. I've been looking to switch between two sensors, as well (RTDs). I don't see why it wouldn't work, assuming the switch has minimal intrinsic resistance. Temperature is determined by the PID by detecting the resistance between the two wires of the RTD (which varies with temperature changes in the probe). So long as the switch doesn't add resistance (and I would hope it doesn't...), it shouldn't change the temperature reading, should it?

If you were using a thermocouple type sensor, then I think it would be a different story.

You can't switch between 2 sensors because the switch will alter the current in the wire for an accurate reading. However you could get 2 probes from auber with the twist lock configuration and just switch the the to the sensor you wish to get a reading from and have a switch on the box from bk to rims or herms to tell it which element to control
 
Looks fantastic. Can't wait to see the finish product...and hopefully in action!
 
The fitting and sight glas are from MoreBeer while the thermowell is from brewershardware.com.

I would not use a switch in line with the sensor. You can try it, but I would not recommend it.
 
Finished putting together my chiller and the pump house. The chiller is just a 25' copper coil with fittings sweated on. The pump house include two march 809s connected to the QDs on the top. The fronts are the inlets and the tops are the outlets. I used thermoplastic tubing and stainless 1/2" tube for the bends in the box.

I am almost done. I just need to make two more extension cords to connect the Pump House and then cut up my tubing and I am all done (for now).

Here is the labeled pump house and everything sitting on the stand.
