24 Information SILVER 21 Decoder
The decoder still has a so-called EMF switch which makes it possible to adjust the decoder to
different motor types. Depending on the motor type used, it is possible that a digitally controlled
locomotive cannot reach an adequate maximum speed compared to a locomotive in conventional
operation. If this is the case, activate your EMF switch by setting Bit 6 in CV 50. The locomotive will
then reach a higher maximum speed while the minimum speed is also slightly increased.
4.3 Running notches
The decoder can be operated in the 14/27 or the 28/128 running-notches mode. This setting is
made in CV29.
4.4 Disabling of delay
Use function 4 (ex-works setting, can be altered in CV60) to disable the starting and braking delay
as well as the constant braking distance during operation. The delays are disabled as long as the
function is active.
4.5 Constant braking distance
Functioning: During the transition from one running notch to running notch 0 (e.g. by moving the
turning-knob of the manual control to the left limit-stop), the locomotive/train covers a settable,
defined braking distance. This braking distance does not depend on the speed of the
locomotive/train.
4.5.1 Setting the constant braking distance:
The braking distance is defined by the value set in CV52. Since the motors and gear ratios of
locomotives vary, the braking distance differs from locomotive to locomotive even if the same value
is set in CV52.
