I have a pair of Z-Stuff DZ-1011 dwarf signals. Each has 3 wires, one red, one black for +18v and common respectively, plus a white wire.
Pamphlet says “by connecting the white wires together of two DZ-1011s, when one block signal changes, the other will also change to indicate that the track is occupied.”
Well, no, it doesn't operate that way at all. One operates normally, i.e., goes from green to read as sensor is activated. The other comes on red and stays on red, regardless of what the other signal does.
Idea is to have a signal at each end of a tunnel. When tunnel is occupied, both should be red. When not occupied both should be green. Both should turn red simultaneously as a train passes either. I can't make these signals behave that way.
