Vonsworld Posted November 29, 2014 Share Posted November 29, 2014 Hello I recently bought a Lenz Silver+ decoder since they are supposed to be very good at running older loco motors. I've installed it in a Hornby HST DMU. This train previously had a Hornby decoder installed and it ran well at higher speeds but was not very smooth at low speed. I'm using a new Elite controller with the latest firmware 1.4. When I placed the loco on the programming track it straight away started to move at a slow constant speed. When you try assigning an address to the loco, it does not respond, it just keeps running along at a crawling pace. If you press the STOP button it does respond and stop, and when you reset the stop function it just returns to it's usual crawl. It doesn't seem to respond to any speed commands or address number changes. Has anyone seen a problem like this before please? and has anyone successfully used a Lenz Silver+ decoder with Hornby Elite? Thanks Link to comment Share on other sites More sharing options...
Rog RJ Posted November 29, 2014 Share Posted November 29, 2014 The loco shouldn't move at all on the program track as the programming track is normally dead. The only time a loco should move is when it is actually receiving programming pulses, when it normally does a tiny shuffle back and forth. . Did you program the old decoder with the same setup, did you have the Elite then or a different controller? Can you program other models on the program track?

papajulietdelta Posted November 29, 2014 Share Posted November 29, 2014 Hi I have several 21 pin and 8 pin Lenz silver decoders that work perfectly with my Elite However, I use Sprog + decoder pro to program them. Never tried the Elite. Maybe you have a bad one. Cheers Link to comment Share on other sites More sharing options...
96RAF Posted November 29, 2014 Share Posted November 29, 2014 I've never seen a loco actually proceed along the prog track, only twitch, flash its lights or make a sound as a form of confirmation depending upon the decoder. As stated above the programming current should be too low to run a motor as protection for your decodder. Link to comment Share on other sites More sharing options...
2e0dtoeric Posted November 29, 2014 Share Posted November 29, 2014 Have you disabled the DC function? If the decoder is 'hearing' corrupted data, it might be thinking it is a noisy dc power feed. Link to comment Share on other sites More sharing options...
Vonsworld Posted November 30, 2014 Author Share Posted November 30, 2014 Thanks for your responses and suggestions. I have tried out all your advice but to no avail. Have also emailed Lenz support so will see if they have any suggestions, but otherwise I'll retuen the decoder as faulty. Link to comment Share on other sites More sharing options...
Rog RJ Posted November 30, 2014 Share Posted November 30, 2014 then probably a duff decoder i understand the warrenty for lenz is excellent if new a replacment will be sent ,check out lenz website for other warrenty conditions lets go back to your rough running hst ,which decoder were you using ? did you alter the back emf cv 10 ? Unlikely to be a duff decoder. The programming track normally has no power on it to allow a loco to move, so with no power on the track how can a duff decoder make a loco run?

96RAF Posted November 30, 2014 Share Posted November 30, 2014 Not no power just limited power by intention to protect the decoder Link to comment Share on other sites More sharing options...
Graskie Posted November 30, 2014 Share Posted November 30, 2014 Are you sure you are using a totally separate programming track connected to the correct controller terminals, VW? You shouldn't get any response to function instructions on your programming track. Link to comment Share on other sites More sharing options...
