MTH PS 2.0 Starts up when power is applied in DCS mode

Sal S2,  go to this thread as GGG has given somethings to try on this very problem see if any help for your issue.

Sal,  Do you have other PS-2/3 engines and do they work with your set up/TIU?  This helps eliminate the TIU as an issue.  Are Red and black wires correct?  Red from output to TIU.

I just did a test on a ps 2 loco that worked with no issues several months ago and I got the same result of starting up as soon as power came on.

I was having ps 3 signal issues as well. TIU has been suspect for a while but I didn't think it would cause that behavior in a loco. I always blame the loco first  :-)

Thanks

Sal,

Three things to check:

• Make sure that the TIU's red LED comes on when power is applied to the TIU and then blinks as many times as you believe the TIU's ID# to be, For example, TIU #1 should blink once and then come on steady.
• Make sure that the DCS signal is turned on for all TIU channels: Menu/System/DCS Setup and press the AON soft key
• Trace the wires between the TIU channel and the tracks to ensure that the wire from the TIU channel's Red output terminal goes to the track's center rail, and that the wire from the Black terminal goes to an outside trail.

Sal, when you say "power up," I assume you mean turn on power to that track, and that the TIU has already been powered up.  Do you turn the power on by feeding power to the TIU input,(which one?) or by turning on a toggle switch that is between ZTIU and track?

What happens when you press "startup" while the sounds are playing?

I have the same problem.  It occurs with only one engine, I have another engine on the track as well, but it waits for me to start it.  The other engine starts up when power is turn on and the only way to control with the DCS remote is to shut it down and restart the engine, then everything works fine.  MTH recommended that I reload the sound file, does that make sense?

You don't have to shut it down. Just press Startup.

Make sure that the DCS signal is turned on for all TIU channels: Menu/System/DCS Setup and press the AON soft key.

   If your using only one channel at the TIU why do the others have to be on?
