Troubleshooting a ground-faulted motor
In this video, a troubleshooting method of locating a ground-faulted motor is discussed. The method and information provided are relevant to the Roach system and in particular Gen 1 configurations. (Though many aspects of this method are transferrable to other systems/configurations)

Electrical structure of conveyor at DGE9
zhlédnutí 937Před 3 lety
Basic electrical layout of conveyor system at DGE9 (Gen 1 Roach Site). This video will serve to establish a baseline understanding of the wiring structure from a hands on perspective. That understanding provides invaluable information toward effective troubleshooting when required.
whats up with maintenance workers leaving wire duct covers off? I spend lots of time designing and building these controls systems and I hate it when a maint worker just dismantles it.
Superb explanation 👌
Dude more videos
Excellent video demo. Do you provide troubleshooting services to clients via video and your service rates?
Thank you. Would have been much easier if you used a drawing instead of photos. Even a hand drawn schematic would have been better.
I'm really new to maintenance first week. I really want get this but at my job training ain't so great any advice
Thanks. Just got a Maintenance ii position at a Fulfillment Center. Will begin 301s this week.
Hows ur job going?
so beaut full
You do know that it was running so fast that it was physically impossible to get the packages,i.e to "buff". Part of the reason for the strikes.
I’m not sure if this is the right place and just started this video. But.. I just hooked up my new cocci conveyor belt and it only runs on slow speed… the speed control does not do anything when I turn it up. Brand new machine and electrician just put on a plug and wired in a corresponding power line. Any ideas electrically as to why the speed control would not work? Thanks to whoever can take a crack at this issue. Thanks I’m advance and looking for advice.
Wow, no way would I allow wire nuts and even worse wago type connectors in a control panel on a machine that vibrates. Unless, of course, I was making bank on call ins.
What’s a good / bad reading?
Would be amazing some diagrams as company. Thank you for the video and your time!
Any more videos?!?!?
What's Up Devildog SF
Very informative! Just had a dead short to ground in a seven segment a couple months ago. Couldn’t you do the initial isolation by ohming A+ A- at the plug?
Absolutely! I have a broadcast video posted on how we do resistance checks on our PMs and we use the plugs. If you’re interested hit me up on chime and I’ll send you the link. When we made this video it just seemed a little easier to show it on the terminal. I actually wanted to make another one showing the isolation on the plugs and actually chasing down a bad motor vs simulating. But every since we have converted to resistance checks on our PMs we have had 0 motor issues :)
Great video. Excellent explanation. Hope we can get more videos. Thanks!
Thanks for sharing .
Any info on loss of communication on between 2 conveyors
Why you stop making these 😩
Same at DBM5
Just out of curiosity, once you've narrowed down your ground fault to a particular conveyor bed, would it not be easier to put your meter leads in the A+ & A- reading ohms and just unplug one motor at a time to see if the reading changes? Or are they in series?
No they are in parallel. If you have GEN2 design you are correct this would be easier. But with Gen 1 design (junction box and wago connectors) it’s not very easy to “unplug” so if you isolate one of the motors in the middle at the junction box you can measure both ways and eliminate motors that aren’t the issue. If you just put it on A+, A- and start disconnecting motors you might end up disconnecting all of them. But there’s more than 1 way to skin a cat. The important thing is understanding the concept. If you understand that you can adapt the micro details of the method to adapt to your style and what works best for you
have they made the up grade by adding a relay confirming that the 24v power supply is on?
They have not
Thanks dude
Very informative thanks. We have the same conveyor.
Hello everyone! Update: we are getting some feedback from other sites that the method has worked for them. One site the “bad” reading was 6.9 Kohms… which is still in the bad range. I have personally always seen in the ohms when it’s bad, however, I have seen flex fail at 20 kOhms. So the threshold is somewhere in that low Kohm range for failure.
