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.
\nAdditional advantages of the ABC technology:
\n\uf0b7 All locomotive functions (e.g. front lighting) can still be switched while the locomotive stops in front of the signal.
\n\uf0b7 Programming in operational mode (POM) possible.
\n\uf0b7 The locomotive can reverse away again from the signal!
\n\uf0b7 A locomotive can pass in the opposite direction, even if the signal is at “Stop”.
\n\uf0b7 Shunting is possible, even if the signal is at “Stop”. Simply activate the shunting mode!
\n\uf0b7 No short-circuits when crossing section points between the driving and stopping sections.<\/p>\n
BM1: How does the BM1 work?
\nWith 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.
\nTechnically, 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
\ndecoders. 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.
\nIf 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.<\/p>\n
Compared to the simple BM1, the BM2 module has the following advantages:
\n\uf0b7 In addition to signal stopping, “Slow approach” (HP2) is also possible.
\n\uf0b7 Easy control of the module using light signals and semaphore signals fitted with
\nswitches.
\n\uf0b7 Even rear-powered (pushed) trains (push-pull trains, commuter trains, motor coaches) stop at the right spot.
\nDepending on the signal setting, you can use the BM2 module to direct locomotives to stop (for
\nHP0), to pass (for HP1) or to slowly approach (for HP2). Of course, you can set the speed for
\nthe slow approach in the locomotive decoder.
\nThe BM2 has two control inputs. Depending on which one is active, the BM2 sends the information “STOP or “SLOW APPROACH” to the decoder.
\nRear-powered trains (pushed) and push-pull (commuter) trains? \u2013 no problem!<\/p>\n
Divide the section in front of the signal into a driving (A) and a braking section (B).
\nWhen the rear-powered (pushed) train in the driving section reaches the braking section, the
\nBM2 switches the driving and braking sections to asymmetrical digital voltage. As the pushing
\nlocomotive is already located in the driving section at that time, the decoder recognises this
\nasymmetry and switches to \u201cStop” or “Slow approach\u201d, depending on the signal setting.
\nThe length of the driving section must be calculated so as to fully accommodate the longest
\ntrains passing this section. The length of the braking section depends on the braking delay
\nand\/or distance set in the locomotive decoder.
\nTrains passing in the opposite direction do not initiate a braking procedure.
\nThe above procedure requires that the leading coach of the rear-powered (pushed) train
\nis fitted with a power consumer, e.g. interior lighting.
\nUsing the BM2 at the end of a block section
\nYou can use the BM2 module to complete a block section of BM3 modules. In a typical case,
\nthe entry signal to a station would be at the end of a block section. By setting the entry signal,
\nyou, as the conductor, determine whether an arriving train may or may not enter the station.
\nThe BM2 has a control output designed for this purpose. Connect this output to the BM3 control
\ninput that controls the previous block.
\nMaximum continuous current-carrying capacity 3.0 A
\nVoltage at signal input (AC or DC) DC: 11…24 V, AC: 8…24 V
