Reply to "Errant voltage/DCS SPST toggle issues"

Sean, sounds like you have no breaks in the power rail, a big continuous loop. The signal is traveling around and around. There is enough power in left in signal that the engine sees a copy of the original. You've created the perfect argument for blocks. I suspect that one gap somewhere in the power rail would stop this.

It isn't necessary to block off the common rails for DCS but it shouldn't cause any problems. It's just work you don't really have to do.

The blocks next to each other don't have to be connected to the same handle or transformer but this will make your gaps more critical so you don't overload a block. I'm using two PH 180s and there are two places on the main where gaps are separating blocks fed by different transformers.

I am wiring with single pair of feeders to each block.
