Locos running at full speed, out of control

[Stefan Lersch]

Hello Per,

I'm sorry but I run DCC only. I can't help you here.

[Per Olsen]

Hi again.

I spent several hours today fixing the problems from yesterday.  It was actually 4 locos that went crazy.  I checked all decoders, the ALL have Uhlenbrock decoders (ID=85).  And none of them had analogue disabled (I have disabled them now).  I will have to go through ALL my other locos and disable analogue.  I have mostly ESU decoders.

Regards,
Per

Hi again.

Stefan:  One question:  If you only run DCC, do you also use locos with MFX decoder?

I am working now with disabling the analogue in all my decoders.  But it does take some time..  But a big problem came today:  One of the locos that I already HAVE disabled the analogue drive, today ran away at full speed out of control.  AGAIN.  So disabling the analogue did not help.  It has a ZIMO decoder.

What more can I do?  Suggestions?

I am stressed now....

Regards,
Per.

Hello Per,

I have N scale. There's no mfx in N scale.

Have you checked the Zimo decoder if the analogue mode is really (or still) disabled?

[Per Olsen]

Hello Stefan.

I re-checked now.  It does have a Zimo sound-decoder.  RailCom and Analogue is still disabled.

Regards,
Per

Hello Per,

which CVs did you check at the Zimo decoder? Maybe it's another CV then 29 which is responsible for analogue/digital.

[Per Olsen]

Hello.

Yes (of course.. ) I checked the Zimo CV-list.  Here is what it says for CV29:

#29 Basic Settings
Calculating the value for CV #29 is due to
addition of the individual bit values,
weighted according to their respective
position on the basis of the following table
Bit 0: 0 or 1
Bit 1: 0 or 2
Bit 2: 0 or 4
Bit 3: value 0 or 8
Bit 4: 0 or 16
Bit 5: 0 or 32
Bit 6: 0 or 64
Bit 7: Value 0 or 128
In ZIMO cabs MX21, MX31, ... the CV
presentation is also bitwise, ie calculation of
the bit values is no longer necessary!
0 -63 6
Bit 1 = 1
Bit 2 = 1
Bit 0 - direction behavior -> 0 = normal, 1 = reverse
Bit 1 - Travel system -> 0 = 14, 1 = 28/128 speed steps
Bit 2 - Conventional Automatic switching (analog mode) -> 0 = off,
1 = on
Bit 3 - RailCom -> 0 = not active, 1 = active
(! CV 28 must be 3!)
Bit 4 - the speed table ->
0 = off-Kl. CV #2, #5, #6
1 = on Char. by CV #67 - #94
Bit 5 - Decoder Address:
0 = 1 address as per CV #1
1 = 2-address as per CV #17 and #18
Bits 6, 7 always 0 (bit7 = 1 when turnout decoder)!
Example values:
#29 = 2: normal direction, 28 speed, no analogue operation,
characteristics, CV #2, #5, #6, short address.
#29 = 10 as described above, only with active RailCom


So, as with ESU and others, I normally use value 2 or 3 (if reverse direction).  So it should be correct...

Regards,
Per.

Hello Per,

this looks good to me. Hmm, sorry, I don't have another idea.


I just googled for it and got two hits:
The first decoder had a cold soldering area.
In the other case the user disabled all other protocols then DCC. So he switched MM ans M4(mfx) off. That worked.


Some write the Zimo decoder are rubbish some write they don't have any problems with it.


I'm afraid you have to find out.

[Per Olsen]

Hello Stefan.

No, I think it is not a bad solder, as it happens with several locos.

Yes, I would like to switch off all other protocols.  The problem is how?  I have checked CV47.  In my locos it has different values.  Many of them have 0, which should mean no protocol at all.  I also have values of 32, 16 and 13.
ESU:  Mostly 0, some 13
ZIMO: 16
UHLENBROCK:  FAULT, some 32
So I am a bit reluctant to change it, as I am not sure I am doing the right thing.... Normally I would have liked to have the value 1 (only DCC), as recommended in one of the ESU manuals I found, they say it is best to have only one protocol if there is a problem using a multi-protocol controller.  Like the TAMS I am using.

What say you?

Best regards,
Per.

[Stefan Lersch]

Hello Per,

you should switch off all other protocols in the Tams. I don't know how to do that because I only have one. I'm sorry but this is beyond my knowledge.

[Arnold Schmidt Wtbg]

Hello Per,
unfortunately, I can not speak English, I'll try a translator.

Have you ever looked at the logs with the program "CV-Navi"?
There is the possibility to query the logs as they are stored in the TAMS and change.
I hope you can read my gibberish overheard.

I do not know if it helps you with your problem.

Sincerely, Bergen, Norway

[Per Olsen]

Hello.

Stefan:  Well, I do need Motorola for some of my older locs, so I cannot switch that one off.  I do suspect that the MFX should be disabled, but I do not know how to do it.  I cannot find it in the manual either.

Arnold:  Hello !  English is NOT my native language either, but I try as best I can    For german language:  I am able to read some, but I do not speak it very well....  You may try to write in german (if you keep it simple, for me    )  I will probably manage to understand it.

No, I do not know that program, sorry.

Regards,
Per.

Hallo Per,

ich versuche es auf deutsch.

CV Navi ist ein Hilfsprogramm der Fa. TAMS welches man sich kostenlos herunter laden kann:


https://estore-sslserver.eu/WebRoot/Store11/Shops/642f1858-c39b-4b7d-af86-f6a1feaca0e4/MediaGallery/15_Download/Software/setup_CV-Navi_2.7_release_20180118.exe

Mit dem Programm kannst du die TAMS auslesen und unter dem Reiter "Lok" siehst du deine Loks und dessen Protokoll mit dem sie in der Zentrale angelegt sind.
Außerdem kannst du auch von dort die Loks ansteuern.
Wenn du an den Parametern irgendetwas änderst muss du auf alle Fälle unter System dieses speichern!

Vielleicht kommst du mit dieser Info weiter.

Viele Grüße ins schöne Bergen

Hello !

I answer in English    No problem to understand you!  I will do this, but it will have to wait till after Easter, as we drive to another part of Norway early tomorrow morning.  I have my laptop with me, so I can read messages, but my layout is not with me

Thank you for your help !

Regards,
Per.

Hello Per,
I think the best way to solve your problem is to switch off the analogue mode in each decoder within CV 29. I guess that it is not necessary to change the setting of the TAMS MC.
On my layout I drive locos with old Märklin decoders (6080 = Mäuseklavier) with MM I-protocoll together with locos with ESU-decoders on DCC-protocoll and some new Märklin-locos with mfx-decoders. These decoders are set to m3 with TAMS MC "m3-Programmierung". All locos work very good with this mixture of protocolls. The version of TAMS MC is V1.4.5o. The menu of the TAMS shows in settings (Einstellungen) and its submenu "Lokformat" the protocoll Motorola. This is the fundamental setting and valid for address from 1- 255 for Motorola-decoders. Address from 256 onward (perhaps till 9999) are automatically set to DCC.
I hope this will help you and I wish you happy easter.
