Topic: Mining disaster with 34 L3+ ASICs, need some serious help!!!! - page 3. (Read 2745 times)

Also, how many amps does the electric car being charged pull?
I saw some articles that gave me numbers 220-240V and 16-or 32-Amps for home charging points. I do not know how the specs of Your charging point, but if it is rated up to 240V 32Amps for charging, then it was some mad wattage being used with all the L3+'s.

If You plug the garage fan in the old outlet (where it was originally) does it work normally?

Clearly can't just be coming from the machines, and the only thing in common they have is the electric supply, so before you look forward into a hardware problem might be a good idea to control your house first.

Maybe You can get some help from here https://bitmainhelp.zendesk.com/hc/en-us/articles/220872007-Possible-problems-for-Antminer-Troubleshooting-for-S7-S9-L3-

Perhaps something happened with some PSUs (don't know how)? You could try taking a PSU from a working L3 and connect it to the one(s) that is(are) not working. If You have a multimeter in Your household, You could test the voltages from the PSU (the output should be between 11.6-13V).

Hope everything works out for You!

It could be a heat problem i heard l3 plus is sensitive to temps over 75

I still cant belive you ran 30 l3 in a house lol on 200 amp no less , just get a warehouse or host em bro

I had a horrible thing happen today and I need guidance from someone who understands the technical aspects of an Antminer L3+. I have 9 of these running in my attic and recently I added 25 in the garage. Most of the miners are running a moderate overclock to ~600 MH/sec using about 1000W. Today I came home to find every single miner displaying a flashing red "fault" light and a solid red light on the front of the control board. I have absolutely no idea what happened. It wasn't a particularly hot day. There were no thunderstorms. My wife was home most of the day and reported nothing out of the ordinary and said around noon all the miners in the garage "had a green light." None of the circuit breakers in my house were tripped. I have the miners hooked to various 230v and 120v circuits throughout the house via heavy duty extension cords. I've done the math and none of the circuits should be overloaded. I have a 100 amp sub panel in the attic that usually draws around 85-90 amps. I also have a "whole house" surge protector for the attic service. In fact since I had just brought all the garage miners online the night before, I had my electrician go by this afternoon and measure my whole house and attic-only load: it was about 186 amps whole house (I have 200 amp service) and 92 amps in the attic. When I got home all the other electrical components in the house were working, with one exception: a fan I was using in the garage had stopped working, even though it was plugged into a seemingly working outlet. I switched outlets and it started working again. All the lighted ends of my extension cords looked normal. When I got home today I quickly unplugged all the miners and tripped then reset every breaker in the house. Now only a handful in my row of 25 miners in the garage power up. The ones that don't work have a weak flicker of lights on the back when initially plugged in, then the fault and control board lights come on. The rear fan spins (slowly) but not the exhaust fan. Interestingly, the miners in the attic fared better. Only 4 of them don't power up.

Can someone shed light on just what the FUCK has happened here??? I don't understand it. Is it from the overclocking? But why did everything fail at once? My wife was charging her electric car earlier in the day, did that screw something up? And what was up with that fan in the garage? Finally, most importantly, what do I do now??? I just took delivery of the garage batch a few days ago, but I gather the warranty is void because of the overclocking... Is it the control board that has gone bad? If so BITMAIN sells them for $60 each, which wouldn't be too painful of a fix.

I really need some help with this. Thanks in advance if you have any information that might help.
