Default Description
#27
Position-dependent
Stopping
(“before a red signal”)
or driving slowly
by
“asymmetrical DCC sig-
nal“ (“Lenz ABC“)
See chapter
“Stop in front of a red
signal and driving
slowly... “
Or
“ZIMO HLU”
or
DC brake section
(“Märklin brake section”)
see chapter
“DC Brake Sections”
0 =
ABC not
active,
HLU
active,
other
brake
sections
not active
Bit 0 and Bit 1 = 0: ABC not activated; no stopping
Bit 0 = 1: Stops are initiated if the voltage in the right
rail (in direction of travel) is higher than in the left rail.
This (CV #27 = 1) is the usual ABC application)
Bit 1 = 1: ABC stops are initiated if the voltage in the left
rail (in direction of travel) is higher than in the right rail.
If bit 0 or bit 1 =1 (only one of the two bits is set):
Stopping is directional, i.e. only in direction of travel to
the signal, travelling in opposite direction has no effect.
Bit 0 and Bit 1 = 1: Stops are independent of direction
of travel. See chapter “stop in front… (Lenz ABC)”
Bit 2 = 0: HLU train protection system (H, UH,…) active
= 1: Effect (halt, limit) of HLU deactivated
ZIMO HLU is active by default,
in contrast to the other brake modes!
Bit 4 - DC braking section, if polarity is reversed
0 = disabled 1 = enabled
Bit 5 - DC braking section, if polarity
is equal to direction of travel
0 = disabled 1 = enabled
Bit 4 and bit 5 = 1 (CV #27 = 48): stopping when
DC voltage (e.g. by a diode) independent
of the polarity (“Märklin brake section”)

Acceleration
0 - 255
0
ZIMO signal-controlled speed influence method (HLU)
using MX9 or StEin:
or
with the “asymmetrical DCC signal” stopping method:
The value multiplied by 0.4 equals acceleration time in
seconds from stop to full speed.

0
ZIMO signal-controlled speed influence (HLU) with
ZIMO MX9 track section module or StEin
or
when using the “asymmetrical DCC signal” stopping
method:
The value multiplied by 0.4 equals deceleration time in
seconds from full speed to stop.

method (Lenz ABC):

ceiving a higher signal-controlled speed limit command.
