Thanks for your thoughts, it could well be that the 50HZ 18V AC 10 amp supply to the TIU had some adverse effect on the TIU as you say cycles or even noise causing the TIU to lose its handshaking with the WIU, that might indeed be the case because it all works for the first few minutes of startup ! all I can say is that feeding the TIU directly with 18V DC has solved my problem.
( ps the input 1 and 2 are both permanently supplying power to the track hence my comment earlier that the remotes work fine, the TIU and the WIU were both powered up during the issues that I was having).
It might be worth investigating in case some other overseas users are having issues with 50HZ, and unless its a fluke on my setup then the direct DC power to the TIU might solve it.
I understand your TMCC comment, my point was that I could not reconnect them because of the " no TIU found" message, but it works now !
Once again thanks for your efforts
Cheers and a Happy Holiday to all the OGR folks
