I've run across a baffling issue. Some time ago I installed a DR5013 as a reverse loop in current sensing mode, not short circuit. It has worked without issue until I installed a new Hornby TXS bluetooth sound decoder in a new locomotive.?
I have run many of my locomotives, sound equipped and not, through the reverse loop. I even added a layed up Hornby locomotive with TTS sound (an early Hornby sound decoder for those who may not be familiar). The issue occurrs only with the Hornby sound decoders, and only when the sound is turned on. What happens is the DR5013 goes into a short circuit condition and cuts the power to the loop. The red LED next to the reset button flashes until it's reset. If the locomotive is still present, the short will happen again as soon as throttle is applied.
I'm using a Roco Z21 base station and double booster - one booster is providing track power to the DR5013, and the 5013 is linked to the Z21 via Loconet. The 5013's short condition was sending a stop command to the Z21, which cut power to the whole layout, however I've fixed that by turning off the short forwarding from the 5013 to the Z21 via loconet (that's to Iain Morrison's suggestion on another forum). My next action will be to increase the short circuit delay in the 5013 and see if that helps.
I'm wondering if anyone else has encountered a similar problem, and if so, how they fixed it? My likely long term solution is to replace the 5013 with something better (maybe wait until the Yamorc version comes out - hopefully this year).?
