¿ªÔÆÌåÓýI helped a chap out with a layout where he was getting all sorts of spurious occupation messages from his DR4088 and the solution was to reduce the cable runs and run as few in parallel as possible. When we required we also use heavier(better?) cable at 16/02 rather than the 7/02 that he had used. This removed all the errors completely. His layout is around 6m end to end and his longest cable runs were 4m and creating bundles of 20+ wires. ? Many Thanks ? Iain Morrison ? From: Colin Bennett via Groups.Io

I am experiencing false triggering of inputs from section tracks furthest from a DR4088 which I suspect is caused by using long lengths of parallel cables using figure 8 wire as Kato Connectors: https://www.osbornsmodels.com/kato-24-825-unitrack-dc-extension-cord-10963-p.asp) ? In some cases I have 3 connected in series making cables 2.5m long. ? Is there any way that the input of DR4088 can be desensitised so that it triggers at a greater current draw that the 2mA that is stated in the manual? ? I do not have an Rrampmeter to determine if any current is drawn in an unoccupied state. ? If I cannot then I will need to split the cables down the centre or add a new DR4088 closer to the offending lengths of track. ? Those connections with only single length of cable are fine. ? Many thanks ? Colin ? |
