I recently bought the above from a friend in Basel, Switzerland and upon getting back to London tried to run it on a C-track loop controlled by an MS2. When the stop button was released it went full tilt round the loop. Guessing the DIP switches were set to analog I took the body off and all were set to OFF so I set the switches 1, 3, 6 & 7 to ON (Address 9 the factory setting). When I set the MS2 to the database settings for the 3618 and released the stop button nothing happened at all. I deleted the loco on the MS2 and told it to find the loco, which it did naming it as MM2-9. The address was correct and the protocols on the MS2 are set as MM2,MFX. When finding the lights did flash on the loco but it still wont respond to the MS2 controls at all.

Any suggestions please.


Cheers

M 3618, whaaaaaat !! no way it is MFX and certainly not with dipswitches, what planet are you on John ???? It's a BO 6090 type

Get your MS2 instruction book out Sean and start from the beginning about "Entering and Configuring a Lokomotive" page 5-8 then 13

Hope you have one ??

Good luck

Agreed

Hello

The behaviour that you explain is very strange. The 6080 decoder is the first generation of märklin decoders and is understand only Marklin Motorola old (MM1), I have experience running this kind of decoders with my IB as MM2, but is is a posibility, so, please change the protocol of your MS to MM1, if possible.

Other way to do something should be to out the decoder in analog (all switches to off) and try to run with a analog trafo, although I supposse that everything will be ok.

Next possibility is in digital operation, does the lights change?, Is it possible to switch the lights off and on? Are the cables in the locomotive in the right conection?

red from decoder to pick up slider.
braun to ground (body of lok)
black to a brush
blue and green to the stator motor
grey to the front lamp
yellow to the rear lamp

Please let us to know the results.

best regards and good luck

The MS2 has only three protocols (DCC, MM2 & Mfx) so cannot change it to read MM1.
The lights do NOT respond to the MS2 controls.
The loco did go forward at top speed uncontrollably when all DIP switches set to OFF and power applied.
Have remembered that I have a 6647 transformer/controller, found it and connected it to the loop. The loco responds to it very well even though I forgot to change DIP switches to all OFF. The 6647 has no way to test the lights on the loco.
Checked wires and could find no loose ends etc. Very difficult to trace all wires to their correct connections.

Have also read the delta problem and moved the switches several times, no luck.
Also cant understand how decoder is read by the MS2 in the "find loco"but wont respond to commands.

Sean

Sean,

I suspect that the loco has a simple Delta controller which is not able to communicate with modern types of digital steering such as MFX.
The fact that the loco was responding well to the conventional 6647 controller says enough.
If you have the outerbox of the loco it should show the Delta logo.
If the instruction book is available,the booklet has an instruction how to set dipswitches for Delta control only.
I have the Rheingold Br 18 with Delta control,i will check the booklet and will revert.

Cheers,
Paul.

Sean,

I have the Delta controlled S3/6 BR 18.4 Rheingold version.
As such it has the Delta control module inside with 4 dipswitches only.
The digital controller 6090 has 8 dipswitches.
The loco should run at all times with dipswitches set as follows:
1 ON
2 OFF
3 ON
4 OFF
5 ON
6 OFF
7 ON
8 OFF
This mode is called "Address for all operating modes".
Please try and let us know.

Hello

The 6080 decoder must work in a environement with MM2, I have some loks with these decoders and works with the IB sending MM2 commands.

If the lights doesn't respond to MS2 controls means that the decoder is not able to understand the commands or the address is not right, in your case it seems that the address is set ok

"The loco did go forward at top speed uncontrollably when all DIP switches set to OFF and power applied. "
This is the normal behaviour of a analog lok in a digital environement

The lok works well with the 6647 trafo, so the motor and its conections are ok

In my opinion this can be some incompatibility between the MS2 and the decoder, there's only one thing to check, the red cable from the decoder must be connected to the pick up slider, and the brown cable to the ground (chassis, body) of lok. In some cases this decoder doesn't understand the commands if these two cables are swapped, so I recommend to check this cables, maybe using a digital multimeter, if not, wait until you have your 60215, or reset the MS2 to factory settings, I have read some extrange failures with MS.

Best regards

Hi all,
I checked the red and brown wires which appear to be correctly connected.
I then did a factory reset on the MS2 and then selected the M3618 from the database and.....hey presto the loco responded exactly as it should, backwards, forwards and lights etc.

Many thanks to all who helped especially HO and amartinezv who hit the nail on the head.

Will keep this solution in mind for the future.
