DCS AIU/DZ-1000 SWITCH MACHINE/DZ-1002P REMOTE WIRING ISSUE

I had the same problem. If you have the ability to change the location of  the switch motor(s), example: on the cross-over pair, that works.  You still may have to reverse the red and green led's.  Note that the LED's are polarized, there is a small flat spot on one side that aligns with the plug-in receptacle.   Both Ross and Atlas switches allow for (4) different switch motor locations.  Note in this video the switch motor pairs working the cross overs.  Position of the switch motors, was key, to them working together.  Control is with pushbuttons, (2 for each switch motor pair), wired exactly per color code, and a Lionel SC-2 controller that would be similar to your DCS control.  Mouse over the image and click on the triangle to access a video.   Best wishes with your project.    Mike CT.

If the controller is right and dcs arrows are wrong, my reaction would be to switch the 1 and 2 connectoons on the aiu.

Thanks, guys.  Mike, I can move them around, but these are situations where the controller would be in the way of something else.  However, if it fixes the problem, I may have to make other changes to the area around the controllers.  Thanks for posting the video.

RJR, that was my first reaction as well, and I did that and it didn't make any difference, which makes it all the more puzzling.  I will spend the day trying to get the right combination.

Thanks, guys, for your replies.

Normally I would hook up the DZ-controller  first    but maybe start with the aiu to get the arrows correct, then work in the controller and leds. 

switching the 2 AIU connections  as RJR mentioned should get the arrows correct shouldn't it.  It's  been a while since working DZs.

I disagree with Gregg, based on personal experience.  Get the controllers right first.

I agree but why aren't the arrows on the remote working correctly?   There sure are a number of combinations to get everything just right.   I suppose the LED on the switch motor might be the best indicator which way the switch is lined.  

Because the wires on the aiu are crossed.   Getting the controller right is the bear in the tent.  Getting the arrows/buttons to match is duck soup.

Good thought about starting with the remote and eliminating the controller buttons until the DCS/AIU is in alignment with the switch operation.  All AIU wiring connections are correct & have been buzzed out for accuracy to the terminal blocks & on to the switches.  Will report back shortly.  
Thanks again for all the help, everyone.

Why do you say aiu witing is correct?

Gregg, switch motor leds are only accurate in 2 of the 4 possible motor locations.

Mike CT    who's 44 tonner on the turntable?

RJR...Right...

It's tricky. especially with crossovers and a wye configuration , 3 ways etc.

Well, I guess I have to open "The DCS Companion" and read up on the AIU.  It is reversing two switches in the remote.  Switch no. 13 is switch 14, and 14 is 13.  13 is on AIU 1, and 14 is on AIU 2.  The reason I said the wiring is correct is that I did continuity checks from the AIU terminal to the end of the wire.  They are going where they're supposed to.  I terminated the wire on a terminal block, and added the switch machine and remote controller.  I have spent all day tracing wires and testing combinations of these 3 elements.  The best I can do so far is that on one switch, the DCS remote is correct but the remote controller is flipped, and on the other switch the DCS is wrong but the remote controller works properly.  It is only in this configuration that all of the LEDs light up on the switch machine and controller.

I may delete those 2 switches in the AIU and move the wiring and add them back in.  What a frustrating day.

Mikey, I'll try again to be clear on getting the arrows right:  (1) forget the remote/AIU and any wiring diagrams you may have; (2) get the controllers to where you're happy with the lights; (3) if the arrows are wrong on the remote, go to the AIU.  ON the AIU you'll see for each switch 3 terminals, labeled 1, 2 and IN.  Move the wire connected to 1 to terminal 2, and the wire connected to 2 to 1.  The arrows will now be correct.

I have 2 crossovers where I have only one controller throwing both switches.  Arrows are correct and lights are correct.  So it can be done.
