I have three concentric loops of track, electrically and mechanically isolated. I have two TIU's. One TIU powers two loops and uses aux. power. The other unit powers the third loop with track power. Only one hand held unit. All are 3.1 levels.
DCS acts funny when all tracks are powered. Hand held unit reacts very slowly, if at all. Turn off third loop and everything is normal. what is happening with the TIU's? Are they interacting? How can I solve the problem?
