I think I've figured out how to wire the DZ 1000 switch machines to an AIU (or two), but I'd like to make sure I'm correct before I begin wiring. As background, I'm using mostly Ross Ready turnouts with a few Gargraves thrown in. Even though I will be using both DCS and Legacy on the layout, I want to have push button controllers for the turnouts until I'm more comfortable with the remote(s).
(1.) I will use a ZW to power the switch machines with a Z-4000 as track power - check polarity, yes? Okay, Commons of both transformers connected together, and the ZW and Z-4000 phased properly This is very important if using the automatic electric non-derail wiring.
(2.) Here's what I think: I should connect the ZW to a terminal block (red to 12 VAC and black to a U post on the ZW), from the terminal block, run power to the AC terminals (right word?) on each of the 15 DZ 1000's. Middle terminal.
(3.)The common (black) wire from the terminal block goes to the C terminal on each of the DZ 1002 controllers, that controls the particular turnout.
The yellow and green wires from the DZ 1000s connect to the L and R terminals on the DZ 1002. Unfortunately you can not reverse these wires to change throw, The light indications won't work properly. You have to reposition the DZ 1000 switch motor to one of the other mounting locations on the Ross Switch to get the correct switch throw that corresponds to the button pushed. Follow the exact wiring diagram. Applies when wiring paired cross-over switches.
(3a.) Automatic electric non-derail can be added at this point, using the short rails, isolated/insulated, either, through, or out, on the ross switch, see the diagram.
(3b.) Note that the red and green indicator lights on either the pushbutton or the switch motor may have to be reversed, there should be instruction on changing the LED indicator lights/location, note that the LED's are polarized, there is a flat spot on one side, that corresponds to a flat spot on the sockets, either the switch motor, or the push buttons.
(4.)From the DZ 1002, I'll need to run wires from the L terminal of the DZ 1002 to #1 on the AIU.
The possibility exist: that L to #1, and R to #2 may have to be reversed L to #2 and R to #1. The switch throw via the remote should correspond to the DZ 1002 buttons/and indicator lights.
(5.).............. a wire from the C terminal on the DZ 1002 to the IN port on the AIU. Any common connection will work, if the two transformer commons are connected and the transformers phased properly.
(6.)...............a wire from the R terminal to the #2 port on the AIU.
The possibility exist: that L to #1, and R to #2 may have to be reversed L to #2 and R to #1. Switch throw via remote should correspond to the DZ 1002 buttons/and indicator lights.
I'd greatly appreciate any suggestions, tips, advice (and, of course, corrections to the above) that you can provide. Thanks in advance.
