Crete-heads! Owen Blevins, ConcreteAnswers.TV. Today were going to listen to Scott Humphrey, DHE Nobles president, talk to us about the electrical system on a Lo-Pro 427s back end. Its an awesome piece of machinery and Scott is going to give you a great tour of the electrical system componentry of the 427 mobile batch plant.
Hi, my name is Scott Humphrey, Im a CON-E-CO dealer. Today were here in Las Vegas for the 2010 World of Concrete and behind me is our CON-E-CO show plant. It is a CON-E-CO Lo-Pro 427. The back side of the plant we have the CON-E-CO UL-certified motor control center. One of the advantages you see here is that we have circuit breakers, we dont have any fuses inside, across the top is your breakers with individual motor controls. Lower, you have your individual starters and of course on the bottom here you have 120 volt I/O connection going back to the control panel. When we troubleshoot these panels, we actual convert from the panel down where its 120 volts that were able to go through and diagnose whether we have a cellanoid, valve or motor or potentially even an issue with the control panel. The conveyors these days have a variable speed drive, these VSDs or variable speed drives are automatically controlled by the batch computer. The batch computer automates it by looking at the pounds per second per discharge. In addition to these standard panels well take all of these drawings laminate them on the inside of the door with the I/Os called out, so for troubleshooting its pretty easy to figure out which terminal block youre looking for with a graphic display of the cellanoid coil and you can come down here on the bottom and determine whether its a plant issue from here up, or whether its a batch computer issue from here down. Through the side of the panel we have individual 120 volt coils that go back into the plant for the motors, as well as the individual controls for 120 volts.
Hey Scott, great job. Couldnt have done it better myself, thats why I had you do it. Hey, ConcreteAnswers.TV. Check us out on the web. See you next time.
Wow! Variable speed unite. You mean like the ones that melt and switch on ludicrous speed without any heads up. That's just awesome!
