CV Description Range Default
Value
**
50 Bit 2
Brake momentum on DC operation.
Used to achieve prototypical braking at red
signal indications if conventional DC control
is disabled. (CV29.2 = 0*)
0 = locomotive proceeds with track-voltage-
dependent speed inside the conventional DC
section.
1 = locomotive brakes in the conventional DC
section with preset brake momentum.

Bit 0
Directional or Independent Headlights:
0 = Headlights are directional.

Bit 1 Front Headlight Dimming Control:
If CV51.2=1, the value in CV52 is used for
front headlight dimming with the dimming
controlled as follows:
CV51.1=0: Front headlight always dimmed
CV51.1=1: If CV51.0=0, function F1 dims
front headlight; if CV51.0=1, function F4 dims
front headlight.
