Chrissaf Posted November 27, 2018 Share Posted November 27, 2018 Which controller were you using when they started playing up and if possible the revision state of the firmware at the time. There is a correlation between a certain controller and accessory decoder failures in my files somewhere, which will take some digging out and as I am prepping to fly to UK soon, I may not get to dig it out. I have spoken to it before on the forum so a search may find it. If all else fails call HCC and tell them about the (old) problem and which controller it was.

Chrissaf Posted November 27, 2018 Share Posted November 27, 2018 Can the R8247 and R8216 ancillary controllers be repaired as I have four which do not want to be programmed or say they haveno error messages I have had them at least a coupleof yearsthankyoubob J Link to comment Share on other sites More sharing options...
Chrissaf Posted November 27, 2018 Share Posted November 27, 2018 You can try to write 8 to CV8 and reset the R8247 decoder to factory default. But you can't do that with a Select controller. You need a controller capable of writing to CVs such as an Elite or eLink. Link to comment Share on other sites More sharing options...
96RAF Posted November 27, 2018 Share Posted November 27, 2018 I found it - it was a fault generated in a specific configuration only. A Select bug and R8247 Port 1. More info available when the OP reports back. The answer to the first question is yes they can generally be repaired.Rob Link to comment Share on other sites More sharing options...
robert_jarrett Posted November 29, 2018 Share Posted November 29, 2018 Many thanks for your replies,I have found the answer to try 8 on cv8 on a previous post thank you all once again. Bob jarrett Link to comment Share on other sites More sharing options...
Fishmanoz Posted November 30, 2018 Share Posted November 30, 2018 So have you solved the problem by writing 8 to CV8 Robert? Link to comment Share on other sites More sharing options...
robert_jarrett Posted December 2, 2018 Share Posted December 2, 2018 Just to let you know that two which I reset would not work after only port after programmingone had two ports only workingone working on three portsI have ordered a new onecan you possibly let me know wher I can get the snubbers from as it does all point to shotsI am using elink and have been on it for at least two to three yearsmany thanks bob jarret Link to comment Share on other sites More sharing options...
Chrissaf Posted December 2, 2018 Share Posted December 2, 2018 ...can you possibly let me know where I can get the snubbers from as it does all point to shorts..Make your own. For each snubber you need just two components. A 100 Ohm 2 Watt resistor and a 0.1uF [0.1 micro-Farad] Ceramic capacitor rated at 50 or 100 volts. Far far cheaper than buying a ready made one./media/tinymce_upload/518f4adea7d1a7869cb5ed55f5f63fb7.jpgI had a R8247 that was damaged by 'shorts'. I fitted my home made DIY snubber about 5 years ago and have not had a single R8247 issue since.. Link to comment Share on other sites More sharing options...
96RAF Posted December 3, 2018 Share Posted December 3, 2018 R8247...one had two ports only workingone working on three ports Not applicable to your situation as you are using eLink, but if the dead port was number 1 then that was symptomatic of the Select induced failure mode. The bug in v1.1 (only - all other versions are OK) caused a latent operation of R8247 port 1 until it failed. The fix was to simply update the Select firmware as just resetting or even replacing the R8247 and connecting it back to the Select would fail the new one, ad infinitum. If your Select is at v1.1 then you are advised to have it updated before using it to operate R8247 accessory decoders. Rob Link to comment Share on other sites More sharing options...
robert_jarrett Posted May 14, 2019 Share Posted May 14, 2019 Hi RAF96sorry it has been so long in coming back to you.never enough hours in the dayIn refeference to you snubber diagram,it doesn’t taker much to confuse memy controller elink to a connector and wire to the track I understand but wire sto th R8247 I do not as I have eight R8247 can you put me rightmany thanks bob jarrett Link to comment Share on other sites More sharing options...
Chrissaf Posted May 14, 2019 Share Posted May 14, 2019 In reference to your snubber diagram, it doesn’t take much to confuse me. My eLink controller to the snubber connector and onward wiring to the track I understand, but wires to the R8247 I do not understand, as I have eight R8247. Can you put me right?.It was my snubber drawing not Rob's..My drawing said "To R8247(s)" as in plural. So your eight x R8247's A&B DCC input terminals are just wired in parallel across the wires. With that many R8247's.....if you haven't done so already....I would recommend upgrading your eLink 1 Amp PSU to the 4 Amp one [Hornby P9300]../media/tinymce_upload/98051d616b9f4223b180547e332c0960.jpg.Since you have updated a later post to indicate that you have an eLink, then you can use RailMaster & eLink to perform a factory reset of the errant R8247s..'How To' is explained in this previous post of mine [4th post down on the page]..https://www.hornby.com/uk-en/forum/post/view/topic_id/9065/?p=2.Remember that any 'programming & resetting' of any of the eight R8247s requires that particular R8247 to be disconnected from the above wiring and terminated directly to the 'Prog A&B' terminals on the eLink via a pair of dedicated temporary wires..

robert_jarrett Posted May 15, 2019 Share Posted May 15, 2019 Hi ChrissefSorry I picked the wrong name,also for not realising connecting all R8247s, I’m afraid you get like that at my age.so now I have a lot of wiring to domany thanks fo you helpBob Jarrett Link to comment Share on other sites More sharing options...
