For anyone having EMI issues I highly encourage you to read this manual from Allen-Bradley cover-to-cover. https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/gmc-rm001_-en-p.pdf After reading it, I changed a few things in my panel and it has been rock solid ever...

Here’s a pic. My question is instead of running all of these loops from COM to COM is there a better way?

Yeah I was noticing the same thing. Huge voltage drop on channels 6-8 and I'm using the largest wire gauge possible with the terminal blocks. So I'm assuming you haven't come across a board with a single common? If so, what is my best option here? Maybe a ring circuit with channels 1 and 8...

How is everyone wiring their relay board? I have the recommended 8-channel DIN mountable one from the order list with 24v coils. My issue is that all the devices controlled by it use 24vDC power so I have all the commons on the relay channels daisy chained and the first linked to the 24vDC bus...

@BrunDog Gotcha. I get what the loop would look like but but how do I tell it to only loop for x seconds or x times before exiting going on if the switch state doesn't change?

What is the proper format to script a time delay for a wait command? I am writing my auto brew script and I would like it to be so that when the brew alarm is triggered it waits for me to click continue or auto advances after 5 seconds in certain places. For example, with hop additions when the...

Will definitely try playing with the RTD wires tonight strange though that they are all running parallel but only one of them is displaying the spikes (RTD 1). In terms of separation I tried to layout the bottom rail so as to accomplish this. The far left is RTDs, then analog sensors, then DC...

The entire panel is 240vAC the only item that uses 120v is the glycol chiller so 240v main distribution breakers and then the 120v chiller has a fuse built into the device for protection. The terminal block next to the left hand ssr is not bonding the ground and neutral it simply is acting as a...

Okay so interesting results from tonight's experiments but definitely a step in the right direction. First, isolating the DC ground immediately helped, the intensity and frequency of spikes when switching local inductive loads was drastically reduced. I then traced my wire routing to ensure as...

I agree something is definitely off here. I will snap some photos and upload when I get home tonight. I did pop in a second MOV across the relay contacts for the inductive load (glycol chiller) and this did nothing to reduce them. I'm going to try floating the DC ground tonight as well and see...

@Ozarks_Mountain_Brew I'm lost as well. So your saying you use diodes on signal wires like a check valve would be used in plumbing?

@BrunDog Yes all grounds are tied together and this bus is tied to protective (AC) ground. All the EMI I am seeing is when high-draw inductive devices turn on or off. To me there are two separate things that need addressing. The first is the EMI generated by ac elements connected to the panel...

Where are you placing this diode and what type did you use?

I'm just noticing some RTD spikes (well drops to -196C actually) on my system. I was able to solve my earlier problem with them by installing diodes on my contactors which prevented the spike when shutting down the contactor. However, now I am seeing spikes from all sorts of places. I installed...

It was just the BC application PC was working flawlessly and I did not get any warnings beforehand. What I have found is when I click close application on the windows taskbar it will normally give BC the kick and pop-up with the shut down options which I then cancel out of and goes back to...

I can’t offer any help on your situation but for me in the past couple of days I’ve experienced two incidents where BruControl froze and required a restart. The scary part was on the second one when I restarted it enabled my element and pump with values which I had used prior to shutting it...

I was actually able to figure it out last night and it was a simple noise issue coming from the pwm line. I noticed that when I checked the voltage on the tachometer channel with my VOM the reading instantly dropped to normal and when I removed the probes it jumped back up out of range...

Yeah the manual is definitely on the spartan side but it is an awesome pump will have to upload a photo when I get home. Yes, I only observe the noise when the pwm control signal from the arduino is engaged even when it too low to engage the motor, when its off there is no reading. I had hooked...

Gotcha. What would a script and variable element look like? Would it be possible to create another script (or possibly the same one) that could disable the counter element and re-enable it after that period via a button? My motor is a BLDC type made by Micropump. There are four wires that...

Couple questions about counter elements I am using three counter inputs two are hall effect flow sensors (one for my RO system and the other in my recirculation loop) and the other is an RPM sensor on my pump motor. 1) How do I change the element in BruControl to only display the Rate of flow...
