On the one hand, defining the different Configuration Variables (#3, #4, #23, #24) offers prototypical accel-
eration and deceleration behavior, but is, on the other hand, often obstructive to quick and easy shunting.
Therefore, the momentum can temporarily be reduced or eliminated altogether with a dedicated function
key. Also, during shunting maneuvers it is sometimes helpful to to restrict the speed range of the speed
controller to a partial range (half range).
CV Denomination Range Default Description
#124
ATTENTION:
bits 2, 3, 4, 6 (i.e. selec-
tion for shunt key func-
tions) only apply when
CVs #155 and #156 = 0
(these allow extended
selection and are prefer-
entially applied to new
projects).
Shunt key functions:
Half speed, acceleration
deactivation
WHEREAS:
Bits 0,1 (i.e. TYPE of
acceleration deactiva-
tion) always apply, also
together with CVs #155,
#156.

Selection of a shunt key for
Activation of 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 shunt key for
deactivation of ACCELERATION 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 the key (MN, F3 or F4) for
Deactivation of 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 acceleration/deceleration
deact.
if bits 0, 1, 4, 6 = 1, i.e. CV #124 = 83
Bit 7 = 0: SUSI-Schnittstelle aktiv (oder Servos,

In extension of the settings of CV #124, if the selection
there (half speed on F3 or F7) is not sufficient, because
another key is wanted:
CV #155: Determination of the function key, with which
the half speed (= highest speed step results in half
speed) can be switched on.
If CV #155 > 0 (i.e. a key is set), a possible assignment
in CV #124 is ineffective.
If CV #155 =
= 0: CV #155 is not active, so CV #124 is valid.
= 1 - 28: Function key F1 - F28
= 29: Function key F0
= 30: MAN key
Bits 7, 6, 5: Modification of the "half" speed".
= 000: Speed according to speed step, multipl. by 0.625
= 001 ... 100: ... speed step, multiplied by 0.125 ...0.5

This CV overwrites the setting of the F keys in CV #124
(Bit 2&6) in case it is not satisfactory. The set range (Bit
0&1) of the acceleration behavior does not change.

If CV #156 > 0 (i.e. a key is set), any assignment in
CV
#124 is ineffective.
If CV #155 =
= 0 means CV #155 is not active, so CV #124 is valid.
= 1 - 28: Function key F1 - F28

= 30: MAN key
Bit 7 = 1: Suppression of switching the light when re-
versing direction.
The settings of CV #124 about the type of deactivation
or reduction still apply, thus:
CV #124, bit 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.
Typically, CV #124 = 3 is set to achieve full deactivation
(unless other bits in CV #124 are also set).

The MAN function (or MAN key on ZIMO controllers)
was originally designed for ZIMO applications only, in
order to cancel stop and speed limit commands applied
by the “signal-controlled speed influence” system (HLU).
This function was expanded in later software versions to
include “asymmetrical DCC signal stops” (Lenz ABC).
If ZIMO decoders are used with non-ZIMO systems
which do not have this key (rarely with HLU, usually with
ABC), a function key can now be assigned with CV #157
to cancel a signal-controlled speed limit or stop com-
mand.
