LGB 23101 Glacier Express

Just treated myself to the LGB 23101Glacier Express locomotive and 4 matching coaches, but don’t tell the wife…
Just reprogrammed the loco address and been playing around with the various functions etc, all on a rolling road inside a heated garage. It says function 9 activates/deactivates the ABV, any idea what this is as I cannot for the life of me work it out!!!
 
I have an LGB diesel which has 9 = AVB off. Wish I could help you.
 
From several years ago:

A question was asked in the LGB Anniversary Ge 4/4 II thread recently about F9 and ABV. ABV is somewhat explained in the Märklin Digital Club Newsletter, Vol. 28 No. 2.

ABV anglicized stands for Acceleration/Breaking Delay - the momentum effects that can be programmed in the decoder. Momentum effects are normally active in a mfx decoder. The F9, ABV function key turns the momentum effects off. Why?, you might ask. Well, perhaps in shunting maneuvers when you want the loco to respond immediately to start/stop throttle changes or if the momentum effect is about to cause a crash as an alternative to the emergency all "STOP".

I can confirm this is exactly what it does from testing earlier today to verify it's operation. Turning momentum off is particularly noticeable when the acceleration and braking delays a are set to give more realistic momentum effects.

Have to say I hate momentum, I always turn it to zero for my trains as I like to have direct control. But as my line has max scale speed of 20kph (all chips and speeds regulated to as near to this as possible) you perhaps can see how irrelevant it would be.

Makes sense but any ideas as toggling F9 which should turn ABV on/off I think doesn’t seem to make any difference?
 
Hi, right I have been playing around a little more with the loco. The F9 does toggle the ABV, but only with the running sounds F6, turned off. When you turn the running sounds on, F6, you have around a 3 to 4 seconds delay from when you open the throttle to the wheels actually starting to turn. Does anyone know if this is meant to be like this? Turn running sounds off and you have an instant response or delayed response dependent upon where the ABV is set. Any ldea’s anyone. Does anyone else have the same locomotive to compare to?

That behavior is normal for the LGB F7 that I have, controlled by the stock dcc /m4. When the engine sounds are on, the momentum effects work and delay acceleration and braking. With the sound off, then there is a quicker response to throttle inputs.

I like the idea of momentum - it reminds one that they are driving trains - sadly I don't have the option on my 1:20.3 trains, although I did have a good session on a Gauge 1 loco (with carriages) at Peter Spoerer's open day many moons ago - the loco and train belonged, I believe, to Mr Fosworks.

It was a useful introduction before I started driving miniatures (with paying passengers :worried: ) on the CMR. There is no such thing as direct control/instant response in 1:1 land :nod:

Momentum is ok if you are driving round on a circle and want to practice stopping at a particular place, but on my Timetable Railway it drives my vistors nuts. Particularly when shunting and trying to stop a train precisely in a limited length passing loop.

Oho, but that's the skill - just like a real shunter :p:p
 
Hi another question. I have noticed that with some of the sound functions that you need to press the function button once to activate the sound, which is normal, but then you have to press it again when it does nothing, then it will activate the sound once again when pressed. So effectively every other press operates the sound functions. Is this correct? It’s like you turn it on, then have to turn it off, before being able to operate again?

All the functions can be set to momentary, or 'latched'..
DCC tends to be triggered by a 'falling-edge' to the control, so momentary, the button (signal) is 'high' and when you press it, it goes 'low'. - Release a momentary button, and the signal goes 'high' again.
Press a latching function key, and it is like a light switch. - You will either turn the 'signal' On or Off. - If you turn it On, it will go from 'high' to low, so you have that falling-edge I was talking about. But because the function is set to be 'latching' it will stay low when you release the button. A second press, and the output then changes from low to high. - A 'rising-edge', which a momentary function ignores..

On your DCC throttle (handset) you can set the functions to be momentary or latched, to suit what the decoder is being used for. - A momentary (on whilst you hold the button) for say a whistle, or latching for say turning on the cab-light.

Thanks Philip, where are these settings located in the navigator menu?
 
Ah worked out how to do this. However I can only see that you can do this for functions F1 to F16, how do you do this for F17 to F28…
Hi All, after a bit of googling I believe that it is only possible to alter functions F17 to F28 by reprogramming the decoder CV’s, so I’ll probably leave for now as it’s not a big showstopper!!!
