great combination DINAM&iTrain for gauge Z; but this Locomotive does not start unless I short circuit

Posted by Sandro M.O.L. Schneider on 2024-11-23 16:02 Switzerland

Conclusion and request for support
My first conclusion and judgment is very positive about this iTrain and DINAMO train control system. The concept works and is very convincing. All (analog gauge Z) locomotive run better, smoother and with nicely illuminated lamps (thanks to PWM and HFI from DINAMO).
My above described difficulties seam to come from the iTrain settings and can surely be solved and overcome.
Maybe I pushed by accident some „magic“ control buttons in the iTrain software, that inhibits the locomotives to start? ... or my wiring is still not clean? ... which I doubt, because this was checked by different methods and the wiring corresponds to the drawing in attachment B-).
This behavior shows up only with locomotive Re420 „LION“ 2.
Also I think that maybe my block definitions are not clear, since feedback M_B_0 lights up when NB_0_1 lights up (?). The locomotive is only on one place in N_B_0.
Beside that, all locomotives run cleanly on the analog (not connected to DINAMO) side track with a Märklin regulator; N°67020)
With the above described „bug“ I can not continue to bild the next large track with more DINAMO modules and iTrain software, which is my plan. So please, is there an expert that has a hint for me to solve this problem?
Many thanks for any hint: Sandro M. O.L. Schneider smol.schneider at bluewin.ch

I have also a nice, systematic description with pictures to add.
PS.: My test license will run out tomorrow and I will buy the full license, before that time.

Hi Sandro,

If your loco's report short circuit while there is none, you can try if changing the OCD parameter helps. OCD determines how agressively Dinamo reacts on to much current draw. You can set this through Dinamo(new)Config. It is a TM44 setting. If you change it make sure you change it on all TM's.

Be aware that some loco's will not allowed you to use HFI. Especially the newer "faulhaber" types have very low inductance against HFI and will overheat.

Best regards, Leon

Dear Leon,
you are great, ... so quick response. To be more precise it is not a short circuit between A and B rail, but a short circuit between the block N rail A and block M rail A, hence a connection between the two blocks.

However the hint with the low inductance is interesting and I will check this, maybe the TMC 44 doesn't see this Locomotive? ... I will check.
PS: my complete description is still 700Kb large and I can not send you the pictures, which would make it much clearer.

Dear Leon,
Hurray, the problems are solved ‍✈️ . Many thanks for your support and also many thanks to Christian from Bähnlishop, who helped also to analyse in depth.
Solution 1 (locomotives don’t want to start):
The OCD (OverCurrentDetection) is so quick, that some new locomotives with (probably) internal buffer capacity make a high current peak and the DINAMO system stops. I could see this in the NewDinamoConfig program. Solution: set the OCD to slow and don’t forget to push the button set and tick permanent.
Solution 2 (feedback shows spooky train in one sub-block). Solution 2: Märklin equips their connection tracks with spark reduction capacity, which I had removed, but there was a second capacity hidden under the track, which I had overseen. Now I removed this little beast und the problem is gone. Everything runs smoothly on my gauge 1/220 (mini club) , much better than standard voltage regulation and still analog locomotives
Many thanks for this great product DINAMO train control system
and greetings from Sandro
