Hi,

Can someone please assist?

I have two DC + DCC locomotives (Atlas gold series GP40 10 000 624 and Walthers proto 2000 E7A 920-40548) Both have factory fitted QSI quantum Q1a sound decoder.

Previously they ran on an analog track controlled by QARC DC Quantum Engineer, it worked great, also the sounds.

But when I place them on a DCC layout (Bachmann Dynamis ez command), they immediately start giving the high-voltage alarm (repeated horn blowing), and won't move.
I did a decoder reset on both, with the magic wand. Are they stuck in analog thereby misreading the continuous dcc track voltage?  What am I doing wrong?

The bachmann dynamis works fine, because if I place a Roco dcc locomotive with a ESU Loksound 4 decoder on the track, all works fine.

Is the problem that I used the 2 other loc's analog first? If so, what do I do so they "know" they are now on a DCC track?

Thanks,
Wekke
