Hello,
I have fitted some of my locos with the Hornby 8249 Decoder and now want to upgrade them by installing a remote decoupler.
This device from Märklin works fine with the LENZ standard V2 on F1 (green wire).
Having connected the uncoupler to green and blue wire on the 8249, I was able to activate it on F1 key but can't cut off power, although having deactivated F1 on the control.
I had to hit the emergency stop button to power down the main. After restoring power, the function out of the decoder was off. I could activate it hitting F1 but again was unable to turn it off.
I changed the decoder by a new one out of the box, but the problem appeared again.
Also with a LED hooked parallel to the dcoupler, the same effect.
Any ideas?
