TIU Will not load PS3 - found a TIU replacement.

Seems like a not to complicated layout if your just running 2 loops. With a working PS2 engine. If you do a track signal test. What are you getting for a number ?  
Are your 2 loops using 1 or 2 channels on the TIU ?

My own experience. I have a large layout running in Super Mode. I just place an engine on the layout pretty much anywhere. Nothings removed. Engines are always able to add. At least with the remote. I have the Wifi but really don’t use it. Bought it to try but really prefer the remote. Many times though I do get the message No Engines to Add. Seems to occur more with Proto 3’s. Rather than abort the process. I often times just let the process keep going and usually get the Engine Found on the screen.

I'm using 2 channels on the TIU one from each output on the Z4000. Never had this issue before, it's crazy. I'm confused though about "super mode", what is it?

Super Mode is using multiple TIU’s on the same layout.

Are you using an auxiliary power  supply to power your TIU ? I’m guessing your using the 2 fixed outputs on the TIU to feed your 2 loops. Just make sure you have power going into fixed one if your not using an auxiliary power supply. The TIU needs power into fixed one or the auxiliary supply in order to power up and work.  Try adding the problem engine on the fixed one loop with the fixed 2 unplugged. Remove any engines or lighted cars from the loop.

If your track signal test comes up with a good number. Preferably a 10. You should have no issues adding engines.

what is your signal level on both loops you should be getting very close to 10 !

Are you sure they aren't already in the remote?

If you press read with just one of these on the powered rails and nothing else, does another engine pop up?

If so, press start up and see if the engine starts. If it does, you have some housekeeping to do with your engine list. You aren't adding engines correctly keeping them straight.

If not, test the engine to see if it runs correctly without the DCS signal.

Hi Joe, I've reset remote, TIU, WIU and I have hit the "read" button several times on the DCS app but haven't tried it on the remote, but no result. I can't test the track voltage but I will try running the engines without command control but I have tested several PS3 engines with the same result with the App.

Supermode sends the commands to multiple TIU's at the same time.....

Test the PS-3 unit conventionally does it work?  Is the DCS/DCC switch in DCS position?  Have you tried a recover engine if you know the engine works?  G

and do you have the newest versions of DCS software loaded into all the hardware?

Hi Joe

6.1 on the DCS remote and I downloaded the newest app on the Samsung Galaxy. App successfully loads any and all PS2.0 units. Color me baffled.

Thanks GGG, All PS3 units seem to work conventionally and I tried recovering 2 PS3 units on the track without any success. Would a new TUI/WIU be the way to go? My TIU is one of the first made. Thing is everything worked beautifully 3 weeks ago until I cleaned the track.

I might try setting up a small test track connected just to the TIU (no wifi) and see if it adds. Try each output separately to the test track, as well.

Good idea Richie C, I will try that. I'll get back to you

Okay, I tried disconnecting the 2nd loop running through the TIU and just operating the load sequence separately on the PS3 locomotives, I loaded all my PS2 locomotives without any issue and checked track signal which is 10 all the way around the track, I tried loading 4 other PS3 locomotives without any luck and all PS3 locomotives have the switch in the DCS position. All my power from a Z4000 transformer go in to input 1 and the second loop, input 2. I can't believe I am having these issues. I haven't tried a test track yet as I needed to order the cabling from the TIU to the test track, that will be my next step when I get the cables.

I always noticed that my REV. G TIU's were a little finiky with my PS3 engines. My REV. G TIU's would never work on the bench as they couldn't read nor upload sound files to a PS3 engine without a ton of errors.  Before upgrading to REV. L units, I sometimes had to add them on a test track which what I do now for any engine being added to my layout (TMCC or DCS).

Thank you H1000, hopefully this will be a solution for me as soon as I receive the barrel jacks that I have ordered, that will be my next step to solve this problem.

Thank you for the helpful posts. I was able to locate a slightly used TIU Rev L. Best wishes to all of you.

My old TIU is "toast" so I was able to locate a used TIU Rev L. Thanks for the interest.

was the tiu running 6.1 also?
