Hello,

Few monts ago I've bought one 4F control (model 66045) to connect with the 6647 transformer --in eBay because was not expensive and in order to use the shipping costs of the tracks purchase :)

Seems that the 6647 works as power supply to 66045 ( http://www.lvfocus.com/h-digital.html and one marklin catalogue, pages 74 and 75)

Now we can use the 66045 because have one second locomotive: Piko Taurus with the AnDi 75394 digital decoder, same that this another locomotive: https://www.marklin-user...ws/showreview.asp?ID=245 (The other locomotive is one Marklin BR 81 included with the starter kit)

The problem is that the locomotives doesn't run with the 66045 connected --both, alone. The lights button connects the lights of the Piko Locomotive, and this is the unique action that I've seen from the 66045.

I've connected the yellow and brown 66045 cables with the yellow and brown transformer connections. The red and brown track cables goes to the 66045 same color connections.

The eBay vendor says that 66045 and 6647 are incompatibles because both have speed controller knob that collides --he says that can replace the 66405 if is defective.

Any orientation?

Thanks :)

I am a Delta 66045 user (with a Delta Pilot soon).
The 6647 must be used as a power supply for 66045.
The thick yellow and brown wire must be connected to 6647 at the same color bus on 6647.
The C-rails must be connected to the red and brown bus on the 66045. Do use 66045 to control the speed of your locomotives, do NOT use 6647 at the SAME TIME to control the spped of any other locomotive. Analog and digital are 2 different things.
I think that you must change the address of your Piko locomotive.
Only address 78 (=delta 1), 72 (=delta 2), 60 (=delta 3), 24 (=delta 4) and 80 (=delta pliot) will work.
You must first sort out the address of your steam locomotive.

Welcome to the forum steven86 and benjami..

MärCo: The Piko manual says that the locomotive uses the preset digital address 78 "Marklin Delta steam loco address". One detail: the Piko lights works when I select the first position in 66045 control, but lights doesn't puts on with other positions. I think that the 66045 and Piko 'talks' with the 78 address, but have any problem with the weels :)

I've some doubts with the Marklin BR 81 locomotive. The manual talks about one control (DIP-switch, similar to this:http://francis.courtois.free.fr/jc1/serial/Cases/Inficon/DipSwitch.gif ) with 4 position (1 to 4), but in the real life my BR 81 locomotive have 8 positions (1 to 8). Seems that is more modern that the manual --or not, I can see this 4-switches in images like this: http://images.google.com...q=marklin%20dip%20switch

Without a valid manual, I think that the 72 address means the 7 and 2 in the ON position. I think this because the manual says that the 72 address works with 1 and 2 switchs ON (in the 4 DIP-switch module), but with this combination the locomotive doesn't runs even with the 6647 transformer alone! With the 7 and 2 ON, works fine with the 6647 transformer.

Now I'm worried with the BR 81 DIP switch because my son (aged 8) have anxious with the mechanics and quickly have modified the switchs: all to OFF except 7 and 2. Now he doesn't remember the original switch positions from 5 o 8 switches. By the way, now have one new question: anyone knows the BR 81 DIP switch original positions or have a manual that talks about modules with 8 switches instead of 4? :)

I always put the 6647 knob in zero position.

Thanks for the positions list, Steven86. Are the same that says the eBay vendor.

Seems that the 66047 unit is defective, the speed knob doesn't works.

Thanks for the welcome, stevetrain and MärCo :)

Best regards from Majorca Island.

For address 72, you have to set switches 1 and 3 to ON, all others to off. (Switches 7 and 2 give address 25 which is not supported by the Delta Control.)
Obviously this loco automatically detects conventional operation - no matter which address you select.
If this is a Delta loco (without modification), it does not support switching headlights on and off - you should see light when the loco moves.

Thanks for the utility! I use GNU/Linux (SuSE) but switch.exe works with the Wine emulator (here the evidence: http://bitassa.com/stuff/switch-win-wine.png :)

The programs says that put 1 and 3 ON for the 72 address, maybe the 1, 3, 5, 7 switches correspond tot the four of the little one?

The 66045 works with the BR 81 correctly codified! Only one problem: the stop (66045 to the knob position 0) not is immediate. The loco takes 10 cms to stop. Is normal?

Piko Taurus doesn't works the first time, but I've changed the operation from analog to digital (or vice versa? I'm new to this hobby :) with the 6647 transformer: keeping the control knob in direction-changeover position until the rear lights will start to flash after aprox. 8 secs. Now the Piko loco doesn't works with the 6647 tranformer alone and needs the 66045 control.

All works! Thanks :)

(except the immediate stop :)

Supports lights with the 66045 control, and are very brilliant (and the light tremble a little).

The combination is 1 and 3 on. With your workaround first and with the switch.exe confirmation after, the 66045 now works. More details at my response to Lars Westerlind.

Thanks to all!

Yes, I think it's one of two normal ways to do it. Newer Delta engines have this smoth braking, which i find very good. If you wan't an emergency stop, change direction, or cut the power!
