TTS

Recommended Posts

I spent a good hour this evening trying to get mine running right, I got it better than it was but it’s not perfect. I switched to the alternative alithogram, I think it was cv150 to 1 to change that, then I changed 153 to 255 and 154 to 1. It sets off slightly too quick in speed step 1 but runs fairly smoothly, especially in speed step 2 onwards. Still happy with it for the money, I’m impressed how customisable it is through the CV settings.

Hi Richard,

Thanks for the info, I've spent most of this morning trying to get this Bachmann 37 to run smoothly but with little success. Both my Vitrains 37 and 47 seem ok but just might try your option on them to see if there is any difference.

Oh! and I will be getting in touch for another 20 x 40 speaker☺!

Have a guess Paul!

 

I suspect owner pays to return it then Hornby to send it back.  One or two have done this already so they will be able to say for certain.  I understand what you are getting at though.  Under warranty terms they are being fixed but the owner should not have to pay for decoders not doing what they should.

 

 

I had a blown TTS decoder in my A4 less than 1 year old.

Hornby asked me to return the loco which I did.

£3.90 postage to post it to them.

When I received it back something was catching and jamming the valve gear so back it went, another £3.90.

Received it back after repair and still jamming and catching.

Another £3.90 to send it back.

Finally received it back running OK.

They refunded all my postage costs under their T&C so you should get postage refund if not send them an email.

Wiggy.

heres a quick video, its a lot better than how it started...

Looks smoth enough once it gets going, but is it not possible to correct the moving off? Will let you know how I get on with mine once I have made the changes.

I’m sure it will be, I’ll kept looking at it. Problem is I don’t really know what cv 153 or 154 do!

They alter part of the PID characteristics of the motor. Explain briefly in the TTS manual. A pair of CVs for each motor algorithm option.

Any idea what might slow down the drive off?

Richard have you tried contacting Hornby customer services about this?  I expect they will be keen to know of problems so that they can rectify them rather than leave them and damage the reputation of their product.  From other threads it would seem that they have been receptive to contact.  Just a thought.

Hi Richard,

Have changed the CV settings you suggested and my Bachmann 37 now moves off slightly better than the one in your video.

I used your settings along with the Hornby suggested ones in a Vitrains 37 and 47 and they are as smooth as silk,both of which have the 20 x 40 base speaker fitted.

I take the view that these chips being roughly a  third of the price of a Loksound  or Zimo I can afford to experiment and am prepared to compromise on functionality and performance in order to get more loco's sound fitted than budget constraints would otherwise allow. I am upgrading the speakers as a matter of course so in the worst case scenario (a chip blowing) I will only be £35 down and have a DCC sound ready loco that just needs a chip fitting.

 

So with this in mind I have this weekend fitted a TTS 47 into a Heljan Lion and a TTS 60 into 'Kestral'. I am aware that both of these loco's have mechanisms that in theory  exceed the maximum output of a TTS chip but my loco's never work flat out and max load on my layout is 8 coaches or 20 wagons  on minimum 36 inch curves so not likely to strain the motor.

 

Results of test running so far are impressive. The TTS 47 in Lion is set  up with Cv150 set to 1 (ie the alternative 'linear' speed table). This suits the loco better as it suffered from juddering with the default set up. The downside of the alternative speed table is that transitions of the first 10 or so speed steps are less smooth (but acceptable in my opinion).

 

The TTS 60 in Kestral is as supplied (ie CV150 is 0). This is very smooth from take-off  - almost Zimo like. In deference to the stated peak load of 0.8amp I am opting not to use the lights as they are far too bright anyway and according to my NCE powercab make current demand jump  by 0.5amp.

 

Anyone horrified by the class 60 sounds in Kestral  better stop reading now if they haven't already - next up is a TTS 37 in Bachmanns  Ivatt 10001 then a TTS 31 in a Heljan Co Bo……..

 

Speakers are a Zimo dumbo  and YouChoos in Lion and a dumbo and iphone speaker in Kestral.

 

TTS – cheap as chips sound for the masses – thanks Hornby J

Hi Richard

 

I've just fitted a cl31 TTS decoder in a Hornby Cl31- NOT the railroad version. The default aligorathom set was completely wrong resulting in a crazy stutter, changing this to the alternative set has cured the stutter but, as with you, the loco has no low speed control, goes from 0-20mph in one jump. This is very frustrating and, frankly, very dissapointing despite the price incentive. Please let us all know what Hornby have to say and if this is cureable.

As I have remarked in other threads my experience has been that the motor control in these TTS decoders suits some motors very well, and others not at all, although even the 'best' performance can't come close to that afforded by the likes of Zimo. The adjustment parameters don't seem capable of offering much leeway compared with those found in others. In such cases where decent motor control just isn't possible then 'piggybacking' the TTS decoders  - treating them as a sound function only type - and using another to perform motor control - seems the easiest way out, always provided of course that there is the space for two decoders. I have done this with a TTS +Zimo MX600 in a Bachmann diesel which could only jack-rabbit with the TTS alone whatever the parameters used, and it works well. The total cost is still far less than a 'full fat' Zimo sound chip, and you can always change the speaker to another type/size. That the MX600 was already installed meant that it only cost me the TTS decoder anyway.

 

Whether this is actually worth all the extra hassle is a moot point and will depend on the individual, I did it simply by way of experiment. I very much doubt that having used 4 TTS diesel types in various locos I will buy any more. Instead I will use Zimo at a slower rate and probably replace those I already have at some stage.

Have you removed (or at least disconnected) the fan? If not I would do that first. The TTS can be 'temperamental' at times  - using the NCE Powercab 'Horn' button seems to set loco's running of at speed sometimes. My solution is not to use the horn button. My main range 31 (D5511 - dates from around 2010 I think) was initially juddery with TTS . It is a lot smoother with CV150 set to 1 but my current discovery is that having set CV150 back to 0 via POM it now is smooth at default settings. I have no idea whether this has changed another CV or whether this improvement is permanent (remember I said TTS is temperamental but then so is the Powercab!) but at the moment D5511 is a fine runner.

with the 31 if I remember rightly I set 151 to 255 and 152 to 1 and it worked fine.

 

Hornby were helpful but didn’t give me any information that I hadn’t already seen on here

Yes I've removed the fan assembly (in order to get the spkr in). Will possibly give this a try.

Some months ago I fitted a TTS to my Hornby "full fat" (not Railroad) 31 110. Fan removed.

 

It took a lot of experimenting to get the CVs just right, but I found it really worth the time and effort.  I can honestly say that the motor control I'm getting is now every bit as good as my Zimos. And at £36 each I'm happy to fit a few more 31's 47's and 60's to boost the fleet.

 

With NCE Powercab, I ended up with the following on the 31:

 

CV3 = 100

CV4 = 20

CV10 = 128

CV150 = 0

CV151 = 20

CV152 = 0

CV153 = 80

CV154 = 20

 

I'm now fitting TTS to a Bachmann 47, and have also got it super smooth, but you do need patience (and a nice long program track!). I also found it benificial not to have the sound on while tweaking the CV's. That way you can actually hear any very slight motor juddering or buzzing so you can then fine tune even better.

 

One problem I am still having with TTS though is that I find them too loud!  Even turning down CV182 to 1 (minimum volume) it's too much for my small layout room. I like a "scale" sound!  I've resorted to laying a bit of tissue over the speake!  Needless to say this bodge is not ideal!

 

Could anyone advise if a quieter speaker is availabe - if there is such a thing - please?

I found that CV151 and 152 which both should have been 8 were not right out of the box.  The Lenz 100 would not reliably reprogram them.  However, the gaugemaster loco doctor that i now have programs them a treat

Brave man!  I think this is the first account of TTS in a Heljan that i have read.  The motor output on the chip is protected, so in theory, keeping the lights off should stop it going pop

Hi,

Did you use the same CV changes on the Bachmann 47 as you did on the CL31?

Only purchased decoder at the weekend and stll tweaking the 47 Bill - the CV's are different,  I'll post values when I have it perfect  But it's running super smooth.  I just need to get accelleration and decellerations just right.

Perhaps i have this wrong, but from what i read in the instructions, there were two motor profiles, switchable on CV150.  With CV150 at 0 (default), CV 151 and 152 controlled the motor and were set to 8.  With CV 150 at 1, the other motor profile is used, controllable on CV's 153 and 154.  I think!

Yet, that's what I read too. But will give these values a go, can't do any harm.

In case it helps anyone - I found the only way to get my Hornby Class 60 to run smoothly was to go to motor controls CV 150 at 1 and then to shut off the Back EMF on CV10 completely.

Interesting. This is the only TTS chip I have so far starts both sound and movement at speed step 1 - all the others in my possession (classes 31, 40 and 47) start at step 2. As I said above I fitted the class 60 chip in a Heljan Kestral and I find it is the best straight from the box. My theory was that the cv settings of the 60 chip were factory set to match the finer mechanism and greater weight of the Hornby 60 model - hence the good running obtained with the Heljan model. Your experience suggest that this isnt the case.
