Shunting
tango
with
automatic
coupling
and
decoupling
Changing
the
mode of operation
for
two connected
couplings
on
two
outputs:
t
.
tn
dVIZg,
always
use
the least significant
output
A1 to A7
for the
front
clutch,
so
when using
A1 and
M, use
Al for
the
front coupling
and
M
for the
rear
coupling.
lf more or
less than
2
outputs
are
defined, there
is no difference
in the
sequonce
of
the different
travel
directions
(see
automatic
decoupling
travel).
2. lf the
front coupling
is released
by means
of a function
key
and the driving
direction is
forward
at this
point
in
time, the
coupling
is
swiiched
off when
the driving
direction
is reversed
in the automatic
maneuvering
sequence
(coupling
proqe-
Ouri;.
Ftne rear
clutch
is released
and [he
direction
of travel
is backwards
at this
point
in time,
the coupling
process
is
alsoiriggered
now.
ln the opposite
direction
of travel,
the coupling
is controlled
according
to
the setting
of the
automatic
decoupling
movement.
3.
The entire duration
of
the
coupling
control
must be adapted
to the times of
the maneuvering
tango

CVs

and
137 via CVs

-
(CV125
+
CV126
+
CV127)
applies,
it
is
biggerthan
CV136
+
CV137.
Here, encores
may have
to
be
made on
the
right side of the
inequality, because
in
the
maneuvering
tango the
decoder
only
reverses the
direction
of travel
when
it realizes
that the motor
is really
stopped.
Servo
Control
Deployment
of
a serve
on the decoder
requires
expert
knowledge
in
electronics.
ln CVi66,
it
is
specified
via which
output
a servo
is to be
controlled. lf
the corresponding
bit
is
set,
a control.signal
for a
model
building
servo is
output at
the desired output
(A6
and/or
A7, or
SUSI).
The
following assig.nment
applies
to the con'
nection
pins
oi
the
SUSI
inierface:
Servol
=
CLK,
Servo2
=
Data. The
wiring of
the_ outputs can
be
found in the FAQ
PIKO
in the

operating
a servo

Braking
Behavior

The

(brakes
with analogue

on the
track)
when CV29
bit 2 and
CV27

are
set
to 1
(factory

Brakes
lf
the
decoder
detects
a
lower
amplitude
of
the digital
voltage on one side
of the
track, a braking
process
begins.
0n
which side
of the
rail the digital
voltage should be
more
positive
in
order
to activate
the braking
process
can
be
set
via
CV27:
CY27
=
1, brake when
right
rail is more
positive
CY27
=
2, brake
when
left rail is
more
positive
CY27
=
3,
brake
inespective of
which
rail
is more
positive
The
voltage
differenci
can be set
in
CV97.
The
desired
difference conesponds
to
th9
CV
value
*
0.12V.
lf
an
ABCilow
speed
signal
is
detected
according
to a
Lenz BM2
module, the decoder
brakes
to the
intemal speed
range
(0
-
255) which can
be set
in
CV98.
