Dcs not. Working

Ok hear we go I have z4000 4:10 .2003 TIU put fresh Battery s in remote .I deleted all engines from remote. When I put a engine on track turn power on .To 18v the engine starts up .on it's own when I try to add it .I get no engine found can run engine conventionally. If I hit read button it says find TIU 1 but no dcs engine on track. The red LED comes on blinks 1 time the 18v bulb powers up I have on the out put side. Any help would be appreciated thank you in advance Jack k

Original Post

First, I would recommend what Engineer Joe suggested, that you hook up only a test section of track.

You need to determine whether the problem is the TIU or the locomotive.  Do you have another locomotive to try?  If you get the same results, the issue is, probably, the TUI.

Jack,

First, connect the remote to the TIU's Remote Input port with a curly telephone handset cable. See if things improve.

Next, as Gregg says, ensure that the DCS signal is turned on for all TIU channels: Menu/System/DCS Setup and press the AON soft key.

Third, one more time, ensure that the red TIU output terminal goes to a center rail and that the black terminal goes to an outside rail.

Why does the engine power up when I apply 18 volts ?

Because there's no DCS watchdog signal present. If none of your engines work, there are only 4 possible reasons:

  1. The wires are reversed.
  2. The transceiver board has lifted
  3. The DCS signal is turned off.
  4. The TIU is broken.

I don't know 100% ... You can always try to find the tiu version of the software with Menu/ System/ tiu set up / tiu version..

If you can  find the version without the tether I'd say it's working properly... At least the communications between remote & tiu.  Dcs signal is another story.

Ok. I rebook up z4000 to tiu input side - tiu to dis-block / 18v light bulb ant to track. I opened remote press in RF bord add a peice of foam rubber. I pick up a phone cord hooked it to tiu and remote. Power up to 18v the engine makes its click sound .but I get no dcs engine on track or found .my ps3 engine does nothing. What am I missing I m lost with this. I tried reset tiu And reset the remote .still does not pick up the engine .

Since fixed 1  doesn't seem to be  working  try fixed 2....This is how you might hook it up....hook up one side of the Z-4000 to fixed 1 IN..... This will turn on the tiu so that it can"turn on" ....    function     or  do it's thing

Hook up the other side of the Z-4000 to fixed 2 in... Fixed 2 out goes to the track.

Each tiu channel has a signal generator, It appears fixed 1 is not working so give fixed 2 a try...

A small test  track works the best with only one engine receiving power, the other engines should be removed from the track or parked on dead tracks. good luck.

Jack,

tiu to dis-block / 18v light bulb ant to track.

What does this mean in English?

I pick up a phone cord hooked it to tiu and remote.

Is the phone cord 4-conductor? Is it plugged into the TIU's Remote Input port?

Power up to 18v the engine makes its click sound .but I get no dcs engine on track or found .my ps3 engine does nothing.

Did you add these engines to the remote? You must do so before attempting to run them. Just doing a READ isn't enough.

I tried reset tiu And reset the remote .still does not pick up the engine .

Again, after the reset, did you add these engines to the remote? You must do so before attempting to run them. Just doing a READ isn't enough.

Jack,

But is my fixed channel 1 dead or is it fixable 

First, press the following: Menu/System/DCS Setup and press the AON soft key.

That will ensure that the DCS signal is on for all channels. If Fixed #1 still doesn't work and Fixed #2 does work, your TIU's fixed channel #1 needs to be repaired.
