6.7 ABC = simple signal stop and slow approach
You can carry out a particularly simple signal stop using the ABC braking module. Depending on the
E
signal position, this module creates an asymmetric track voltage in the braking section in front of the
signal. The decoder reacts to this. Combined with the constant braking distance, precise on-the-
spot stopping in front of red signals is not a problem. Of course, passage in the opposite direction is
also possible. The signal indication "slow approach/caution" does not pose a problem; the
respective maximum-speed can be set in CV53.
You can operate all functions during the signal stop or slow approach – you can even reverse away
again from the red signal! These special ABC modules can be used to assemble a very simple
block section. Activate the ABC module by setting Bit 2 (1) in CV51.
The ABC feature is not active whenever the shunting speed is switched on or the delay is disabled.
6.8 Push-pull train control
A push-pull train control can be set if the ABC braking module is used. There are two different
options: push-pull operation with and without intermediate stops. The latter also takes slow-
approach sections into account.
The push-pull train control is activated in CV51, Bit 4 (3) and Bit 5 (4). The stopping time at the end
of the track is set in CV54 (1 to 255 sec).
6.9 Allocating function outputs to the functions of the digital system (mapping)
Here you can define which function of the digital system is used to switch the function outputs on or
off. The outputs can be allocated to functions F0 and F1 (direction-dependent) or functions F2 to
F28 as desired. This is allocated in CVs 33 to 47 and in CV129 to 144.
