EB832 amp watt errors!!

[CavamaroZ28]

I had a bit of a scare the other day when I had a pop and flash come from my neptune eb832. I had a heater plugged into port 6. (Hardly ever turns on, it's just a backup heater)
I unplugged it and turned off the port. When I turn it back on the port 6 indicator light flashes orange. It clicks on like normal, just light flashes. I have it turned and I have error readings showing-
-Outlet 6 wattage error
-outlet 6 amp error
-eb832 wattage error
-eb832 amp error

Again there's nothing plugged into it now and it's turned off but it's showing 1500 watts and 15 amps and fluctuating like it's in use. Unit doesn't feel hot or smell. Has been in use for 3 days now

What was the wattage of the heater you "had" plugged into it? Does that heater still work? Maybe it shorted out and fried the EB832

Each outlet is rated at 7 amps or 875 watts max. Not to exceed 15 amps or 1875 watts total across all outlets on the EB832

It seems like there's a fault in the softwares ability to monitor that outlet. More than likely something fried. I don't recall what current sensor amplifier they use in their circuit but short of an power cycle of the eb832, that might be your issue.

If you can afford to take it off line, taking it apart and looking at that area of the circuit might provide some good data.

Looks like it's built into the micro controller and senses off the shunt.

If a power cycle doesn't fix it. This might be one for @_AV

Open it and look. I’d put money on it that the copper leads in the board have melted/fried. I had some that were so burned the board separated.

Relay is probably toast … each outlet has its own relay. That’s my guess.

Funny enough I just got done repairing the crappy 12v AC power supply in my 832 unit lol. Was running. Extension cords plugged together until the Japanese caps shipped. Had me nervous for fire potential.

That 12v psu is definitely a reoccurring problem with the 832.

I've replaced all of mine with the meanwell psu. That seems to be a permanent solution for them.

It was a 300 watt brs titanium. Idk if it works im a little scared to try it. No visual burns or ark marks on the plug

So I have a extra eb832 and I tried swapping everything over and using fusion and I couldn't get it to work for the life of me. Followed there instructions and the outlet indicater lights would turn on and off but no relay clicking and no power. Ended up swapping the old one back on and switched everything back in fusion and it works but still same issue. I'll take it back off tomorrow and open it up. Try and get other eb832 to work again also. So in a nutshell power cycle didn't work

I can hear the sucker clicking when I turn it on and off

Oh man, are you saying that your backup is faulty?

Some thoughts:

Did you label the new outlets on the new eb832 the same thing?

When hot swapping an energy bar, the new one gets labeled as the same thing except I add a number at the end. That way there's no conflict in fusion and it helps me keep the outlets straight in my head.

Are you thinking the 12v psu is bad in your backup? Or is this all foreign to you and this is the 1st time learning the intricacies behind issues of the eb832?

I'm not confident the 832 can be repaired. But some photos of the backside of the large PCB that has the 110vac plugs attached to it might be worth seeing.

I dont think back up is faulty. It was on a running system I bought years ago. I think my understanding of technology is faulty.
So when I swapped through fusion I didn't lable anything. All my things wer still there and when I flipped them on, the indicator light would turn on but the relay for it wouldnt click on any of them. When I went into the tiles section there was a bunch of tiles labeled for what the outlet was for on the old tank I purchased. Pulled the tiles out and turned them on and nothing.

So the my 832 is labeled eb832_2 and the backup is labeled eb832_5 after I swap through fusion it still says the 832_2 is plugged in and the 832_5 isnt connected. Both would be listed in the module list. I'm an entire newbie to all this. I set mine up 9 years ago and never had to mess with it again until now. Computers ain't my thing but I'll sure as hell take this thing apart and get back with my findings

So when the current meter starts going crazy like this, the problem almost always is around the shunt resistor for this specific outlet. In most cases, the resistors to the controller are fried and in some cases the shunt itself is damaged. On rare occasions, if the spike was too strong and the resistor bank couldn't protect the controller, the controller circuit for this specific outlet may be out also.

One of my repair videos related to this:

 

[BeanAnimal]

ahem... my first question would be why are the current shunts not opto-isolated in a production controller like this?

Nevermind... they would add $10 in production cost

Now now... Let's not aggravate platinum sponsors here.

 

[Sisterlimonpot]

Wow! That shunt disintegrated. I haven't watched the entire video. I wonder if you ended up replacing the 4 resistor pack (lack of a better word)?

And I wonder if it did damage the processor would you be able to cannibalize one from another unit?

Most definitely, the resistor array had to be replaced.
Not only did I replace the processor, but I also reprogrammed the thing, no need for donors ;)
Watch the entire video, it's all like magic :)

I skimmed it (fast forwarding the components removal and replacements). Hehe

I take it that you've developed a relationship with Neptune to the point they've supplied the software to program those? And perhaps they shared the schematics as well in order to be able to trace and probe the circuit?

That'd be a hard no. I just help the community through my expertise and talents :)

 

[Sisterlimonpot]

Then what did you use flash the new processors? Is it generic open source software?
