Michael Armstrong1707820172 Posted November 30, 2017 Share Posted November 30, 2017 I am having an issue with controlling the speed of my Hornby HST fitted with class 43 TTS decoders. Direction lights and sound work fine, both the power and dummy car will play sounds at the same time regardless of direction (I assume this is normal). However I am having an issue stopping the locomotive once it goes above 20mph (it will stop at slow speeds although there is a delay). I have checked CVs which are showing as factory defaults. Currently using elink with railmaster and haven’t had any issues with other TTS locos or any other sound or none sound fitted locos. Link to comment Share on other sites More sharing options...
2e0dtoeric Posted November 30, 2017 Share Posted November 30, 2017 When the train is travelling fast, and you turn the knob to zero, does it eventually slow down and stop, or does it just keep on going for ever?Real trains don't stop dead! So perhaps the deceleration cv needs adjusting to 'speed up' the slowing down, if you follow that! Link to comment Share on other sites More sharing options...
ff2nd Posted November 30, 2017 Share Posted November 30, 2017 Hi Michael. Can you read CV7 on the power car? If so, what reading does it give you? Link to comment Share on other sites More sharing options...
Michael Armstrong1707820172 Posted November 30, 2017 Author Share Posted November 30, 2017 Thanks for the responses. CV7 is reading as 128 on the power car. Having played about with it tonight sometimes it works ok other times it seems to freeze- will not speed up or slow down and lights spot sounds etc are unresponsive where as the dummy car will response (obviously just lights and sounds). I have taken the dummy car off and the problem still happens although less frequently. Having said that even when it is working ok it seems slow to react to commands- certainly a lot slower than the other TTS locos that I own Link to comment Share on other sites More sharing options...
96RAF Posted December 1, 2017 Share Posted December 1, 2017 EriceLink doesn't have knobs, but we know what you mean. Michaelyou say all CV values are at default,but just check CV3 & 4 are set to 15. Also check DC running is off in CV29 using the right click method to bring up the sub table in the CV read facility.it is possible your decoders have a problem so if it persists contact HCC and ask them about it, as there was a problem with programming and directional issue - see Admin post at the top of this forum.Rob Link to comment Share on other sites More sharing options...
2e0dtoeric Posted December 1, 2017 Share Posted December 1, 2017 On-screen graphic representations of knobs or sliders, then! :-)(knobs is quicker and easier to type!) Link to comment Share on other sites More sharing options...
Mk 1 Posted December 1, 2017 Share Posted December 1, 2017 Had this with Sir Chris Hoy. (Javalin). Ended up having to hard wire the power car decoder to the motor to bypass the circuit board. After that, all was fine inluding the lights.Mark Link to comment Share on other sites More sharing options...
Tuliper79 Posted December 1, 2017 Share Posted December 1, 2017 Michael. I have previously experienced near identical symptoms. On one occasion it was because the wheels on the power car were grubby, and on another it was because of some dust caught between a wheel and the electrical pick up. Perhaps a spot of cleaning might resolve the problem. Good luck. Alex. Link to comment Share on other sites More sharing options...
