Re: False Positives YD6016

Dave, ? I am also surprised with your mail, especially as this is the second case I have heard of in as many days and I understood that the different design of the YD6016xx compared to the DR4088xx (note not the DR4018 ?). In the other case it proved to be ballast that was causing the issue because the fixing PVA was bridging across the rails – could a similar situation be affecting you? ? Iain ?

Subject: False Positives YD6016? I have recently experienced an issue with false positive feedbacks on two YD6016 boxes, one was an LN and the other an ES unit.? I am aware if a solution that Iain M shared in a post some time ago using 500 ohm resistors on the DR4018 units which were over sensitive but was surprised to see the same issue on the new YD units.? The problem occurred on the second day of running at a model railway show, and it occurred on both boxes at around the same time. The layout had need running on the previous day all day with no issues. On the second day after about 5 hours we noticed 2 false positives, on different sections of the layout, one on a YD6016LN and the other on a YD6016ES (both connected together). Yesterday I set up the layout again to try and resolve this problem but the problem had disappeared! ?At the show we reset the layout several times but could not clear the issue. our only solution on the day was to remove the feedbacks from Itrain and run the layout in a much reduced way.? Any thoughts on how I might protect myself from this re-occurring as it caused considerable disruption at the show.? Dave, Portland
