Hi, I have a True Line Trains FM C Liner with ESU Loksound which I am running with a NCE Power Cab controller.
Although bought new (old stock) there is no literature at all concerning the decoder supplied with the loco which I find surprising and unhelpful.
There is a definite glitch when running as if function 9 key is pressed the sound accelerates and will not slow down, this is independent of the motor speed which has no effect on the engine sound even with the loco stopped.
The only way to regain motor sound control is to reprogramme the loco or simply disconnect the handset.
Any ideas please as to the solution to the runaway sound and also the lack of decoder instructions with a new loco?
Hello,
IF the prior owner had "upgraded" the decoder, assuming it is a Loksound Select, they may have installed the "FT" version or Full Throttle where pressing F9 enters the "drive-hold" feature and does exactly what you describe, the prime mover sound can increase independent of the motor speed of the locomotive.
However, pressing F9 again should bring the motor drive back to the throttle control where loco speed and prime mover speed are somewhat synchronized.
I would suggest a decoder reset if the F9 function continues to give you erratic behavior.

If you search ESU "Full Throttle" or Drive Hold" you will find more information on it.
I have heard of some ESU decoders made for Rapido, maybe others, that have a "Straight-to-eight" feature which revs the prime mover to full RPM to simulate supplying head-end power for passenger trains. I have also heard complaints that once this feature is enabled, it will not disengage when the function is turned off.
Again, I'm only making a guess at which decoder is actually installed in your engine. The previous owner could have bought the DC version and installed any number of sound decoders.
Good Luck, Ed
Thanks Ed for the very useful reply.
The loco was new old stock bought from Pacific Western Rail Services and the decoder was fitted by TLT, i.e. "factory fitted" and the box end label states DCC/DC sound.
The F9 function is clearly as you describe a rev up function but does not cancel when pressing F9 again...as indeed was your description.
I shall look into the problem suffered by some Rapido locos, with any luck there will be a suitable work around.
The is an ESU forum on Groups.io that might be helpful
You don't need to a lokprogrammer to run the LP program. Conceivably you could download the sound package specific for your loco and figure out what CV's need to be changed.

Thanks Henry for the info on the ESU forum, I'll look into it.
Hi, thanks for the reply.
The loco catalogue number is TLT 500162S A Unit bought new by me and factory fitted with a Loksound V4. The livery is Canadian National green/yellow.
The sound clip was installed by TLT.
I've had it now for a few years but never test ran it properly until now as I'm about to put it up for sale but only after it's running properly.
It should be an easy sound fit for you to do, personally I would recommend the Soundtraxx Econami.
I can post a video of it running if you would like.
Well I tried the reset cv8 to 8 but F9 still refuses to disengage.
**** loco is now running reverse for forward and vice versa, anyone able to advise please?
F9 is manual notching UP and F10 is manual notching DOWN.
If you turn on F9 the notching will increase. If you turn F9 off, it will hold at that notch. In order to bring it back down, be sure F9 is turned off and turn on F10 and it will come back down. Turn both F9 and F10 off to regain auto notching (some versions also required you to be at speed step 0 in order to revert back to auto notching).
Mark.

Doug,
Here is the CV29 configuration for a TCS decoder. It's a standard CV setting so it works for all decoders:
Value Effect
All you need to do is add up the values of the features you want then enter that into CV29. My default setting value is normally "34" for my locomotives, as I only operate them in DCC and don't bother with speed tables. However, since my larger diesels run long-nose forward, I do add "1" to the value of CV29 to make it "35" in order to reverse direction.
HTH,
Tom

It's a standard CV setting so it works for all decoders: Value Effect 32 - Make decoder address 128 or higher 16 - Make loadable speed table active 4 - Enable analog (DC) operation 2 - Use 28/128 speed step mode 1 - Reverse direction the engnine runs All you need to do is add up the values of the features you want then enter that into CV29.

Following Mike's post earlier I subtracted 1 from the cv29 total which switched direction nicely.

I programmed the controller to use the option key as +10 and also tried the alternative method using the shift key and Prog/Esc but no joy as F10 does not cancel F9 and start dropping the revs.
Oddly if F10 is pressed on its own it ramps up revs identically to F9 so that probably explains why it won't drop the F9 keyed revs.
F10 to F19 do appear to work, well F18 anyway, as it seems to be brake squeal.
So there does after all appear to be a glitch.

Lastspikemike To add to the fun of DCC "programming" the F keys are also programmable using obscure hieroglyphics. F keys program differently to CV settings. That's where the manufacturers of decoder equipped locomotives can generate the maximum confusion for owners of different brands.

No, F10 does not cancel F9. You have to turn F9 off yourself BEFORE turning F10 on.
