ABC technology: A Lenz patent that enables the train to slow down in front of a signal and stop with all its functions active. To use the ABC technology, the used locomotive decoder MUST support the protocol and of course, be activated.
Additional advantages of the ABC technology:
All locomotive functions (e.g. front lighting) can still be switched while the locomotive stops in front of the signal.
Programming in operational mode (POM) possible.
The locomotive can reverse away again from the signal!
A locomotive can pass in the opposite direction, even if the signal is at “Stop”.
Shunting is possible, even if the signal is at “Stop”. Simply activate the shunting mode!
No short-circuits when crossing section points between the driving and stopping sections.
How does the BM1 work?
With little effort, ABC manages to accomplish just what model railway enthusiasts crave: Exact stopping in front of red signals and free passage in the opposite direction. By means of simple modules which supply the braking section in front of a signal, the locomotive decoder receives the signal status nformation: if the signal is “red”, the train will slow down and stop, if the signal is “green”, the train will continue unimpeded.
Technically, this is realised as follows: if the signal is “red”, the BM1 module creates in the braking section an asymmetry in the otherwise symmetrical digital track voltage. This is spotted by
decoders. The result is a gentle braking of the train until it comes to a halt, optionally with the set braking delay or set braking distance.
If the train is not to stop, but to continue unimpeded or to start moving again after the stopping time has elapsed, the BM1 will simply be bridged with a switch.
