will travel a settable, pre-defined braking distance. This braking distance
does not depend on the speed of the locomotive/train.
Enable the constant braking distance function (this requires setting Bit
0(1) in CV51. If this bit is not set, the decoder will use the normal speed-
dependent braking delay).
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.
Use a short test section to measure how long your locomotive’s braking
distance will be with a given value set in CV52. Start with the default value
(100) in CV52.
Accelerate your locomotive until it has reached average speed.
At a chosen point in time, set the speed to 0. This requires moving the
speed control to the stop position, if you are using the LH100, keep
pressing the < key until the speed is set to 0 or until the locomotive
address is displayed (if using the LH100, do not press key
! This result
in a locomotive-specific emergency stop and the delays in the locomotive
decoder will not be enabled!).
Measure the covered braking distance.
Increase or decrease the value in CV52, e.g. in steps of 10, and carry out
another measurement. You will thus create a table which will indicate the
braking distances in relation to the values set in CV52.
Important advice: The constant braking distance is only effective if the
speed is changed to 0. If the speed is decreased from e.g. 28 to 10, the
speed-dependent delay from CV4 becomes effective.
The constant braking distance is disabled while the switching speed
function is switched on (default setting F3), or if the function to disable
acceleration/deceleration is activated (default setting F4). Either of these
two features can also be used if you wish to interrupt a constant braking
process prematurely.
The constant braking distance does not function in analogue DC mode.
Function for disabling of acceleration and deceleration delay
Use function F4 (function assignment can be altered in CV59) to disable
the acceleration and braking delay as well as the constant braking
distance during operation. The delays are disabled as long as the function
is active.
Mapping function outputs
Using function mapping you can define which functions of the digital
system are used to control the A, B, C, D, and E function outputs. CVs
33-47 are used for Functions 0-12 while 129-144 are used for Functions
13-28
