Crete-heads! Owen Blevins, ConcreteAnswers.TV. Today we’re going to listen to Scott Humphrey, DHE Noble’s president, talk to us about the electrical system on a Lo-Pro 427’s back end. It’s 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, I’m a CON-E-CO dealer. Today we’re 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 don’t 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 it’s 120 volts that we’re 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 VSD’s 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 we’ll take all of these drawings laminate them on the inside of the door with the I/O’s called out, so for troubleshooting it’s pretty easy to figure out which terminal block you’re looking for with a graphic display of the cellanoid coil and you can come down here on the bottom and determine whether it’s a plant issue – from here up, or whether it’s 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. Couldn’t have done it better myself, that’s why I had you do it. Hey, ConcreteAnswers.TV. Check us out on the web. See you next time.
Nice looking panel. Are all motor controls Square “D”?
