RMweb Gold farren Posted November 19, 2019 RMweb Gold Share Posted November 19, 2019 Hi I am having trouble with one or the other. I am building a layout and having fitted the frist six points motors . I am currently testing the layout before moving on to anymore building. The point motors are feed of the track busbar. I managed to get the frist 4 fully working. A couple of days later I weird up the next two which worked fine but the frist 4 would not work. After much testing nothing seemed wrong I reset them long story short all six worked fine. Come to day none are working. I haven't reset them yet. I ran a couple of loco's but one did not respond to its ID and needed to be re-a dressed. now if i know correctly the id is kept on the dcc chip or point motor in this case. So the question is have i got six faulty point motors or is the controller going wrong Link to post Share on other sites More sharing options...
Nigelcliffe Posted November 19, 2019 Share Posted November 19, 2019 Its probably something in the signals from the DCC system which is causing the point motors to reset. As to which is to blame, its hard to pin down. I'd suggest talking to either the supplying retailer of the point motors, or DCC Concepts, to see if they have any solutions to offer. Sometimes fitting a "track snubber" accross the track will stop the noisy signal affecting things. The "snubber" consists of a resistor and a capacitor of appropriate sizes, the components should cost under 50p. Link to post Share on other sites More sharing options...
RMweb Gold farren Posted November 19, 2019 Author RMweb Gold Share Posted November 19, 2019 Thank you for your answer I'll phone dcc concept's tomorrow and see what they suggest. You say the track snubbed needs to be the appropriate size. Is this something dcc components can help with. As in do the values need to be tailored to the devices in question.

Nigelcliffe Posted November 19, 2019 Share Posted November 19, 2019 I've looked it up, typical snubber values are: 0.1µf ceramic capacitor (rated to at least 25v) and a 100 - 150 ohm resistor, rated minimum 1/2 Watt. Place at furthest end of track runs. Its a cheap thing to try. Nigel Link to post Share on other sites More sharing options...
Ron Ron Ron Posted November 19, 2019 Share Posted November 19, 2019 A DIY snubber, as Nigel suggests, is as cheap as chips to make. However if you’re unsure or not able to make one yourself, DCC Concepts will sell you a ready made snubber, but it will cost a few pounds more.

RMweb Gold farren Posted November 19, 2019 Author RMweb Gold Share Posted November 19, 2019 Thank you both for your replies. I should be able to make one. Just never come across one before. Link to post Share on other sites More sharing options...
