Yes. As far as I have seen, the way to pull 2 voltages off 1 service is mulit-phase. So the system is probably designed without 110V.

Interesting concept. edit: LINK FOR THE LAZY. This guy gets a VERY ROBUST sensor with +-0.01gallon accuracy!

Update: Ironed out some issues in logic during testing. Added alarm handler ack and the start brew button to the main screen! CatahoulaBrewingCo.RSS AdvancedHMI Release 1.1 Update 4/10/14: I got the wireless adapter installed and hooked up to the PLC, but lacked an outlet to plug it in...

PWM pulses ac voltage on and off. Think of it as a light switch that is cutting power to the element. You essentially have a on-off-on-off-on-off pattern where the ONs and OFFs are at some set time interval. For simplicity, let's say that ON-OFF should take 1s, or a 1Hz period. The output % is...

Looking good man!

Fixed :)

Update: Lunch break progress on the Main screen. Designed to look good on my tablet (1280x720), and work well with touch control. The spacing at top and bottom are for a logo, generic info, and a nav bar. Edit: Just realized I forgot the sparge step.... completely. It's not in the logic, nor...

I agree. If you want to improve performance you need colder (or faster absorbing) coolant, or more flow. Easiest, get a pump for your water!

Well it will work :) great idea! In the industrial environment we use large "wort chillers", e.g. heat exchangers, to heat product. We run hot oil (330F-350F) to heat stearic acid mixtures to about 250F-280F. So yes! Good idea, now you just have to find out what your F/min is. Just make sure...

Update: Spent my lunch break writing the rough rough logic in RSLogix. I still need to flesh out the process section. I am also considering wiring in feedback from the relays and PIDs for alarming. Added the .RSS ladder logic and .PDF RSLogix Report with the ladder printed out. edit: The...

Current transformer would go on your incoming power. As close to the service as possible. Make sure it is the same one that you pull 120V off of. Which red wire to what coil? You mean on your mains contactor?

Not yet. Still have to come up with a convention and buy some labels. Any suggestions?

What was the cost of your control panel? $1074 so far. I have bought $576 of parts (and about $200 of parts I am not using). I have an additional $500-$800 to spend on the physical parts, then another $500-$1000 for plumbing. Where have you found your best deals? Amazon. Ebay. ebrewsupply, and...

Autotune is your best bet on that one. Otherwise you have to figure out how to tune a PID yourself, which is far from easy to do correctly.

Yeah. I like them a lot for how cheap they are. The only reason I really chose the ML1200 is that it is free and prewired in a decent cabinet. The RTD cards are absurd though! Now for an update: Started working on the wiring for what I have, trying to get the panel pre-wired for the install. I...

Yes, the air will cool faster than the liquid. You want to at least tape it to the side of the fermenter though a thermowell bung is your best bet.

I guess I haven't been looking hard enough :cross:. I need to give ebay a run through. :)

I don't know how to sub, but I will be following this one :)

Just waiting on funds to get level and flow working. I have analog 4-20ma :)
