Had the engine been working normally at one time, or is this a new engine (or new decoder install)? If it worked at one time, I wonder if the engine was at some point a trailing unit in a consist set up through your DCC system (i.e. not through a CV setting). That might explain why it seems to respond up to a point, but won't move.

Perhaps try changing the engine ID, like add one number to the current ID or just change the short address to 03 and long to 0003 and see if the engine responds to that. (As mentioned, you can change CVs even if you can't read them back.)

  Does the locomotive jiggle when writing CVs? Do you have decoder Pro? Try reading all sheets and see if it walks down the track. Is it difficult to check the motor connections?

 

 

It does wiggle ever so slightly, does this mean anything? I thought I was seeing things as I thought it was not supposed to be able to move on the program track. I don't have a programmer and I will try and get the shell off for a peek inside tomorrow.

I appreciate the help.

 The Loksound does it but not nearly as much as some other decoders. I did a WOW sound in a brass 2-8-0 a month ago and it rolled down the whole yard long program track. I ended up putting it the rollers. The Loksound 5 just wiggles a tiny bit. If you can take the shell off you can see the motor armature go round. I'm doing a Loksound 5 micro right now in an older P2K Alco S-1. I downloaded the sound file through the programmer and set up lights, horn, bell, and others using the programmer. Now I'm creating a roster file in decoder Pro. It takes about a half hour to read all sheets. This is the 12th sound decoder in six months. All that's left is one E8 and a half dozen Alco RS units.  Then I will have nothing but noisy locomotives.

I've seen lots of my Digitrax, Soundtraxx and QSI/Paragon decoders do this on the programming track but I don't recall any of my ESU decoders doing the "dance" during read or write operations. Maybe I just missed it.

Good Luck, Ed

The OP stated he could not read or write CVs.

I seem to be able to write CVs on the programming track and main. On the programming track, the first thing it says is it cannot read CVs, I then hit enter and the programming line appears at which time I can change CVs. The thing will not move. I must have inadvertently changed a CV along the way.

  Loksound 5 only needs the CV8 for a reset. I suspect a motor wire has come loose. The OP stated he could not read or write CVs. The decoder needs a motor draw or resistance across the orange and grey wires for read/write capability.

Hello All,

This might be slightly Off Topic  but...

I bought a Roco EDK 750 Slewing Railway Crane.

This unit uses a ZIMO MX659N18 decoder for crane operation, sound, and independent propulsion functions.

With this decoder; to perform a full reset, not only does CV8=V8 but CV908=V8.

Using JMRI DecoderPro I added to my roster an entry of "Raw CVs 1-1024" decoder family.

This provides direct-to-CV programming and does access CV908.

I understand you are working with a LokSound V5 decoder but there might be a second CV that needs to be re-valued.

Short of purchasing a LokProgrammer, I would suggest contacting ESU directly and posing the question to them.

Hope this helps.

Post Script: The EDK 750 is an expensive item but worth every penny!

  You will have to check the motor connections. The decoder needs a motor load in order to read/write CVs.

Thanks, Pete, I tried all of the above. Horn, bell, and light work, I have sound, the engine sound does not notch up when I throttle up. I get "cannot read CVs when on the programming track.

 Could you possibly have F9 on? Drive hold. When you try to move does the engine notch up? Can you clear CV19 consist address? To reset is CV8=8 then cycle the power.

Can't Reset Loksound V5 Decoder.
Posted by BATMAN on Sunday, June 19, 2022 4:08 PM

I have an NCE Power Pro-R System and it cannot read the CVs on the programming track of this one decoder and I cannot reset it either on the PT or main. Suggestions? 

I get sounds and lights but the loco won't move.

As always, thanks.
