0
Raising or lowering the speed to the next internal step
occurs only if the preceding step is almost reached. The
tolerance for reaching the preceding step can be defined
by this CV (the smaller this value the smoother the accel-
eration/deceleration).
Value 0 = no adaptive accel. or decel.
Tens digit: 0 - 9 for acceleration (1 = strong effect)
Ones digit: 0 -
9 for deceleration
= 11: strongest effect;

ATTENTION
:
Bits 2, 3, 4, 6 (i.e.
selection for shunt-
ing key functions)
are only valid if CVs
#155 and #156 = 0
(These allow ex-
tended selection and
are preferred for
new projects).
Shunt key functions:
Half-speed, acceler-
ation deactivation
Bits 0,1
(i.e. type of
acceleration deacti-
vation) are always
valid, also together
with CVs #155,
#156.

Selection of a shunting key to activate the HALF SPEED:
Bit 4 = 1 (and bit 3 = 0): F3 as half-speed key
Bit 3 = 1 (and bit 4 = 0): F7 as half-speed key
Selection of a marshalling key for deactivation of ACCEL-
ERATION TIMES:
Bit 2 = 0 (and bit 6 = 0): MN key as acceler. deact.
Bit 2 = 1 (and bit 6 = 0): F4 as acceleration deactivation
Bit 6 = 1 (bit 2 irrelevant): F3 as acceleration deact.
Type (range of action) of key (MN, F3 or F4) for deac-
tivating acceleration times:
Bits 1,0 = 00: no influence on acceleration times
= 10: reduces acceleration/deceleration time
to ¼ of the values according to CVs #3, #4.
= 11: deactivates acceleration/deceleration time
completely.
EXAMPLES:
F3 as half speed key, if CV #124 = 16
F3 as half speed key and
F4 to completely disable acceleration/deceleration time,
if bits 0, 1, 2, 4 = 1, so CV #124 = 23
F3 as half-speed key and for Accel. deact.
if bits 0, 1, 4, 6 = 1, i.e. CV #124 = 83
Bit 7 = 0: SUSI interface active (or servos,
if defined in CVs #181, #182, ...
= 1: Logic level activated instead of SUSI.

ATTENTION
in case of CV #125 and #126: change CVs

NOTE
: The fan operation is also determined by the

NOTE
: Large-scale decoders do have special outputs
and additional configuration possibilities for smoke fans!

This is valid, if in one of the CVs #127 - #132 has set on
of the function effects “smoke generation” (i.e. “72” or
“80”): The values in CVs #137 – #139 define a character-
istic for the function outputs (FO1 - FO8; referred to be-
low as FOx).
