Hi. I need some help trying to figure out why I can't control the track voltage with the DCS remote. Last week I purchased a new TIU to replace my original from 2003 because it was giving me trouble reading Protosound 3 engines and I wanted to have a second one as a backup anyway. The new TIU worked fine for 3 days then I noticed as soon as I pushed the handle back on the Z4000 transformer to power up variable 1 track with 22 volts, the track became powered immediately instead of waiting for the track button on the DCS remote to be pushed and then power applied to the track using the thumbwheel on the DCS remote. I can run conventional engines like Williams and Protosound 1, but I have to bypass the DCS remote and use the handles on the Z4000 transformer. Also, when running these engines the horns blow continuously and cannot be stopped on both Williams engines and Protosound 1 engines. I thought it may just be a defective TIU. So on Tuesday I took the new TIU back to the train store and exchanged it for a new one. After 2 days the second new TIU is doing the same thing. I checked the DCS setup menu on the DCS remote to make sure variable 1 is on and was not changed to a fixed track mode. Variable 2 has the same problem. My outer loop is connected to variable 1 and my inner loop is connected to variable 2. I did not have this problem with my old TIU from 2003. I have Barry's book and cannot find any section that deals with a problem like this.
