DR4018 & DC Question
|
Dennis, ? ? ? ? ? ? ?I have not removed the RRampmeter. Ryan from Iron Planet ran some tests with a RRampmeter, DR5000, DR4018 and a Kato turnout and was unable to reproduce the buzzing noise. Don Jenkins don97jovi@... On Wed, May 27, 2020, 8:10 AM Dennis Cherry <dbcherry@...> wrote:

I understand, saw the post,? just trying to find what is going on.
I am an old technician, trying to eliminate possible problems on your setup. I would like to see if you have tested the turnout as standalone connected to a DR5000.? I have an idea of the problem. Just the DR4018 with DCC and DC power and the Kato turnout with the DR4101 connected.Nothing else connected to the DR4018. Dennis |

Dennis, ? ? ? ? ? ? ?Yes, I have done that. I completely disconnected the DR5000 from the layout and ran the track output wires of the DR5000 straight to the DR4018 signal inputs. I then connected a Kato turnout using a DR4101 to the DR4018. I then connected a 12v 3a wall wart power supply to the power inputs on the DR4018. When track power was turned on there was no buzzing noise from the turnout. I also tried the exact same setup except with the DR5000 connected to a laptop via USB. I ran the DR5000 software so I could throw the turnout and it worked as it should.

Great, that tells me it is working.
My thoughts are: 1. Add the RRAmpmeter to the test bed and see what is happening, if that works then: 2. Check the DR5000 that it is set for 3000ma. and not 1500ma. 3. Check that you have not accidentally reversed a buss wire drops to your track, meter and check you did not reverse a drop. 4. I watched a video of someone who uses the Kato Turnouts and he isolates both rails on the threw and diverging routes. go to about 5:15 on the video. Dennis |

Dennis, ? ? ? ? ? ? ?The RRampmeter is soldered in to the main buss wires and mounted into my fascia, I was hoping to not remove it until it's a last resort. ? ? ? ? ? ? ?The DR5000 is set to 3000 output. ? ? ? ? ? ? ?I have visually triple checked all feeder drops to make sure none are reversed. I have a boxcar painted blue on one side and white on the other. This matches my feeder wiring colors. I can roll the boxcar around the track to confirm where the blue & white feeders are to be located. Makes it easy to not get confused when the track curves in different directions.? ? ? ? ? ? ? ?Most of my Kato turnouts have insulated rail joiners on the thru & diverging routes. There are 2 that do not, they lead into a yard and small engine facility. They will eventually get insulated after I drop feeders to those areas.

Don , Let's start chasing down this buzz. I want you to take out the signal wires and no power going to the DR4018 and turn on track power. if there's no buzzing then It's not the turnout. Next put the signal wires back in so the blue wire is to the right (inside ) and turn on track power If It's still buzzing turn off track power and remove all of the ?but one?DR4101 and remove the common wire, and turn on track power and see if its buzzing still. If still buzzing ,turn off track power and put the common back and take of one of the blue wires. let us Know how that goes. It's always a pain in the ass to find a grounding problem ( The buzzing )

James, ? ? ? ? ? ? ?I will try and do some of these tests this evening. If not it will be tomorrow. Thanks for your help. Don Jenkins don97jovi@...
