RMweb Premium Newbie2020 Posted April 8, 2023 RMweb Premium Share Posted April 8, 2023 (edited) Hi All, I have set up some peco electrofrog points using iP Digital Point motors and connected them through a DCC Concepts Aplha Sniffer to some Cobalt S levers. The points open and close fine. However I am getting a problem woth the frog! When the points are set in one direction the exit tracks are both live! (as tested with a Train Tech Track Tester). throw the points the other way and only one of the exit tracks is live! How can this possibly be!!!

csvt2004 Posted April 8, 2023 Share Posted April 8, 2023 There are 3 wires involved. One goes from the common crossing (frog) to some kind of switching device, where there will be two connections to the supply. If you have got those mixed up, that can cause what you are describing. Make sure the "common" is connected to the frog. 2 Link to post Share on other sites More sharing options...

Help Clive Hi Clive, If you are using a Sniffer, then that suggests you have a separate accessory cointrol bus. You will need to connect the frog via the S2 contacts on the point motor. As per this diagram. Ensure you have isolated joiners on the v-eneds of the point.

I feel such a plank! I'll get that sorted tonight and let you know how it goes. As an aside, when I first tested the points I ran an 0-4-0 over them and all seemed fine - however, what I hadn't thought about was that the 0-4-0 had a "Stay Alive" fitted !!! So, obviously the fault didn't show up straight away! Cheers Clive (feeling rather silly!) 1 Link to post Share on other sites More sharing options...
