Help needed with programming F7 change direction

I'm New, Please Be Gentle
Hi
We are trying to program our LGB F7-A unit to run in reverse using multi train LGB controller 55016p and 55006p - have followed the instructions (we think!!!) and having no luck - any help would be appreciated.
 
I believe it is an original LGB but unit was bought 2nd hand and I dint know how to check - am new to all of this!!!
 
You need to find the value presently set for CV 29, and add '1' to it..
However, the method of setting this using the MTS controller, I am not able to help with..

The factory default value for CV 29 is '4', so you would change it to '5'.
 
You should be able to set the direction of each loco in the consist on the MTS system but someone else will have to advise as I don't have a clue (sorry).
 
If you want to make this change permanent for a given unit (eg: if it's always going to be running back-to-back with another A unit, with or without a B in between), there is a simple "cheat" that will avoid reprogramming anything - just open it up and swap the motor wires (the green and yellow ones) over! Mind you, this will only be "simples" if it's had an aftermarket decoder fitted, if it's all factory-installed then it will probably have all-black wiring and fitted plugs so you won't be able to do that as easily. Ah well, it was just a thought....! ;)

Press both textured clips at the top of the remote inward and carefully pull out the plastic insert.
Slide the programming insert into the remote. On the programming insert are four colored wires:- Connect the yellow and green wires to the transformer
(minimum 2 A). - Connect the brown and white wires directlyto an unpowered programming track, onto which you place the loco with the decoder you want to program. After you have assembled this setup, plug the transformer into a house current outlet.
The display shows .C--
Input the number of the CV you want to program: "29"
The display shows .d-
Input the desired function value: 05
The display now shows .d5
Save the programming by pressing the right arrow button.
You can abort the programming by pressing the left arrow button.
When you have finished programming, disconnect the decoder or remove the loco or car from the programming track.
Hope this helps.
 
Using controllers other than LGB central station will not change the direction of travel in CV29. I have full 3 set F7 LGB and the seller set the last A unit to reverse?on his Marklin unit. Worked perfect for weeks but whilst running it yesterday it decided to change direction of it's own accord and ended up both A units pulling in different directions. Two DCC systems and a lot of CV29-ing later I too looked inside the unit and it was a mass of black wires. I am now going to re-solder the wires on top of the motor to permanently to change the direction of travel unless soneone has a better idea or advises against it?
 
Although you have said 'motor', I am assuming you mean 'motors'?

Both bogies should have a motor in them. - Probably realise this, but might safe you having to take apart again..

Are you runng DC or DCC? I have an NCE decoder which can never make up its mind which way to run on analogue DC - but is fine on DCC of course. I certainly wouldn't expect a decoder to change direction "of its own accord" inder DCC.

But that'll leave the directional lights still the wrong way?
 
Firstly having experienced Mfx decoders in HO nothing fazes me with Marklin stuff. Normal DCC systems cannot change the direction as you would normally with CV29 which is why the shop did it for me with the Marklin Station. With MFX I have learnt make as few if any changes under ordinary DCC. The fact that happily running one minute and without anything being done flipped direction and ended up in a tug-of-war with the other A unit. Then it switched off completely and it has taken nearly 30 minutes sending resets CV 55 Val 55 then it woke up. Like I said nowt raises an eyebrow yet the Economi-400 sound decoder I have in a lot of other stuff is a bloody marvel!

There is aCv to turn down the lights when direction is reversed as per the Massoth manual and I avoid consists like the plague after using them in N and HO scales.

Something makes little sense.

Are you saying that he indeed has MFX decoders, not MTS decoders? And that because of this CV29 does not work according to the standard?

Or are you making a side comment on MFX decoders even though he likely has MTS decoders?

Confused...

Hi Greg,

There are a number of 'gotchas' with the MFX decoders..

Thy default to MFX, so you need to run the loco on the default DCC address of '3', so the decoder knows to 'look' for DCC commands etc.

There is then a problem for those with Massoth Central Stations / Navigators (throttle)..
When you change the DCC address with the Massoth equipment, it not only changes the address CV(s), but attempts to change others as well.. This will 'fail', as the order it does things, and what it does, is not 'right' in the eyes of the MFX decoder in the loco..

You can alter the DCC address with the Massoth kit, but have to do it by altering the individual CV's (short, or long, address CV's and CV29 if necessary).
There is a calculator on the LGB website, for those who do not wish to do the calculations for long addresses manually.

Also, as this is not a Massoth/LGB decoder, but a Marklin/LGB decoder the CV's for things like dimming the light outputs are not the values you expect them to be..

Mainly, they are 'something new' and behave differently to what most have come to expect from the 'de-facto' LGB/Massoth way..
 
Great information, I've heard similar, but less detailed information.

Now, the question I keep asking is: "are you stating his 2nd hand locos have MFX decoders"? I know until recently these were not MFX decoders.

If I have been reading correctly, the LGB F7's could only have MFX decoders if they were of manufacture after Marklin took over LGB...

How can he determine if this is so? Marklin acquired LGB in 2007. Probably did not change the decoders right away...

I thought we were talking about the latest 'F7', just out from Marklin/LGB??

Thoughts:
If ALL loco's are slow, then it must surely be a problem with supply, or configuration of Central Station, or feed from CS to tracks..

Perhaps a crude test wold be to put a meter across the output of the CS, and again at the connection-point to the track? - This would show if there was a problem in the siring between CS and track.

Several feet of track, with different bits of wire feeding it, the rest disconnected form the CS would prove if it was a track problem..

Can the OP take one of his loco's to another line, or a dealer to see what happens there??
