@BrunDog--PID question for you. I'm trying to figure out some appropriate PID settings for my RIMS tube/mash, and it seems like the Max Output % setting in the GUI is not working for me. When I set the MaxOutput to anything other than 100%, the element does not fire. When I set the MaxOutput to...

Happy New Year HBT! Mash plumbing leak testing and RIMS PID tuning this morning.

Whee! More progress! RIMS, pumps, and chiller are bolted to the skirt. Everything else attaches via tri clamps and camlocks, so I can start work on the plumbing!

A couple of other bits of recent progress: my temperature and pressure sensor combo reads both with a single kettle hole (and it's removable for cleaning). Also, I attached my plumbing skirt to the stand via some simple hinges. Most of the time it will be vertical (including during brew...

Dry fitting pumps and valves on the plumbing skirt.

In please.

Hi BrunDog, I'll be back in my panel a bit later today, so I wanted to confirm: for my purposes (suppressing voltage spikes from activating/deactivating contactors) when you say "across the load," you mean to connect one leg of the MOV to the load terminal the other to the neutral terminal...

Progress report (no pictures this time, sorry): most of the way done with splicing, soldering, heat shrinking, and sleeving all of my valve and sensor wires. Still waiting on two more 3-way valves to arrive from China (weirdly by way of Bahrain, with this shipment). I'm about 50% done with the...

Thanks augie. I don't think it was too much current (yet) because I barely had any devices connected to the mega when I killed it. I'll def. keep your advice in mind as I complete my build and have more things connected to the mega. Given that it happened in short order after I turned the...

BrunDog, I bought several of those MOVs from DigiKey to proactively address any voltage spikes caused by inductive-load switching. In the EMI diagram on the BruControl website, you show installation of the MOVs either parallel to the inductive load or across the switching contacts. Is either...

Tagging @augiedoggy.

Good to know. Should there just be a single PSU connected to the ground bus or should I connect my 24V and 5V PSUs to the ground bus as well?

Re: the diagram and things that are unconnected--there are a few signal lines that I did not delete from the wiring diagram (because I'm going to put them back), but I did disconnect everything from the "MEGA" in the diagram if it is not connected IRL. Grounds: All of the AC grounds are tied...

@BrunDog, let me know if this is getting too far afield and I should take this over to my own thread. Below is a complete, current diagram of my wiring as it exists currently. As you can see, I do not have a ton of things connected yet, as splicing/soldering all of the thru-panel connections for...

I just screw the wires straight in bare.

@clearwaterbrewer That's fine--I'll get my wiring diagram updated when I have time. I certainly don't expect in-depth troubleshooting in the absence of in-depth information. I'm just looking for obvious gotchas in the meantime.

@BrunDog, is there any reason the Rugged MEGA wouldn’t work? I’m not going to buy it just yet— I still have a spare MEGA lying around and I’m not that keen on spending $110 on a part that I keep burning up until I’ve done some more significant troubleshooting. But it does seem appealing right...

Sorry I wasn’t clear—I have 2 5500 watt elements that are controlled by SSRs as usual, but they are also physically switched on via DPST contactors. This is so both hot lines to the elements are disconnected unless I have “activated” them. This requires that the contactors’ coils be powered...

Arg. Not sure what's happening, but I keep frying MEGAs. The first two I chalked up to being careless while building, etc., but the last one died after I turned a contactor on and then off again, so I think that it was perhaps a casualty of the dreaded voltage spikes. I'm powering it via a 12v...

I went with two because space is a limiting factor for me. But I'm using a 5500w element in my RIMS tube (a la @BrunDog), so I can heat sparge water on demand if I want to make a beer big enough that I need to sparge. Most of the time I'll brew medium bodied beers, so I'll do no sparge with those.
