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 pre set brake momentum.

Front Headlight Dimming Control:
If CV51.1=1, the value in CV52 is used for
front headlight dimming with the dimming
controlled as follows:
CV51atlas.2=0: If CV51.0=0 (Dimming and
directional headlights both active), function
F1 dims front headlight.
CV51.2=1: If CV51.0=1 (Dimming and
Rule17 both active), function F4 dims front
headlight.

Rear Headlight Dimming Control:
If CV51.1=1, the value in CV52 is used for
rear headlight dimming with the dimming
controlled as follows:
CV51.3=0: If CV51.0=0 (Dimming and
directional headlights both active), function
F1 dims rear headlight.
CV51.3=1: If CV51.0=1 (Dimming and Rule
17 both active), function F4 dims rear
headlight.
