Reverse Loop Module

Help.....It's driving me crazy.
I have a layout in the garden with a loop at each end with LGB ( or are they Masson) reverse loop modules for each loop. One works perfectly, the other I cannot get to work properly . At slow speed the train crosses the isolation fish plates and then cuts out. One pick up wheel on the loop section, the other wheel on the live section. The reverse module has not kicked in. If taken at speed the module seems to work. I have not wired it any differently to the reverse loop module at the other end of the garden. At the other end, slow trains are perfectly acceptable and it whorls well.
Any bright ideas, suggestions, ideas or advice. It's taken 3 hours so far....
Many thanks
 
Yes must be the shortest thread title ever. :-) I thought it was about infra red.

You don't say whether this is DC or DCC and whether you are using the short track sensors or "short circuit" mode. If you have the model numbers of the reverse modules that will help, either from the boxes they came in or the units themselves.
 
Agree with Greg.
BTW you can change the title by clicking on Thread Tools at the top of the thread then Edit Title.
 
Thanks for advice. As you can see I have changed the title.

Its a LGB module on a DC layout
 
So Clive have you checked if they are both in short circuit or sensor mode as per Greg's post? Both from a wiring perspective and module setting.

If they are older LGB types, then they will only have short-circuit mode; only the more recent ones have the sensor mode option like the Massoth unit. The actual part number will tell which it is.
Did they come with some little (about 1") sections of rail and a set of black plastic (isioating) railclamps?

In short circuit mode, there is the possibility that the DCC power circuit breaker is tripping before the "smarts" in the autoreverser do.

The units I use from NCE have trip current settings and sensitivity settings. We use them from Z scale to G scale.

I've never had consistent great luck with the European ones, but then I'm spoiled by the NCE stuff. (And I have never seen any damage or extra wear from triggering on a short).

I have used a loop for years with my "dog bone shaped layout". Isolate each end on each loop both rails. Fit reed switches near the end of the loop. Fit a magnet to the engines. The reed switches operate as DPDT relay which feeds the power to the remainder of the layout so when the reed switch is actuated the power to the rest of the layout is reversed and the train continues seamlessly. The first loop reed energises the relay and the second loop reed de-energises it. If you want more details and circuit I can supply. I have an analogue layout for about 25 years with no problems with this arrangement.
