Introduction/Safety instruction:
You have purchased the Light-Signal Decoder
LS-DEC-NMBS
for your
model railway as a kit or as finished module.
We are wishing you having a good time using this product.
The Light-Signal Decoder
LS-DEC
of the
Digital-Professional-Series
can be easily operated on your digital model railway.
By using a
connector plug bridge
you can
select
if you want to connect
the decoder to a
Märklin-Motorola
system or to a digital system with
DCC
standard.
The finished module comes with
24 month warranty
.
•
Please read the following instructions carefully. Warranty will expire
due to damages caused by disregarding the operating instructions.
LDT
will also not be liable for any consequential damages caused by
improper use or installation.
•
Also, note that electronic semiconductors are very sensitive to
electrostatic discharges and can be destroyed by them. Therefore,
discharge yourself before touching the modules on a grounded metal
surface (e.g. heater, water pipe or protective earth connection) or work
on a grounded electrostatic protection mat or with a wrist strap for
electrostatic protection.
•
We designed our devices for indoor use only.
Connecting the decoder to your digital model railway
layout:
•
Attention: Before starting the installation-work switch off the
layout voltage supply (switch-off the transformers or disconnect
the main supply).
The Light-Signal Decoder
LS-DEC
is suitable for the
DCC
data format
as used e.g. by
Lenz-Digital Plus
,
Roco-Digital
(switching via
Keyboard
or
multiMAUS
only; switching via
Lokmaus 2®
and
R3®
is
not possible),
Zimo,
LGB-Digital, Intellibox, TWIN-CENTER,
DiCoStation, ECoS, EasyControl, KeyCom-DC
and
Arnold-Digital /
Märklin-Digital=
whenever
no connector plug bridge
is inserted in
position
J2.
The decoder is suitable for
Märklin-Digital~ / Märklin Systems
or
Märklin-Motorola
layout (e.g.
Control-Unit, Central Station, Intellibox,
DiCoStation, ECoS, EasyControl, KeyCom-MM
) if you insert a
connector plug bridge on J2
.
The decoder receives the
digital information
via the
clamp
KL2
.
Connect the clamp with a rail or even better connect the
clamp to an own
digital main ring supply assuring the supply of digital information free from
any interference.
Please attend to the marking on clamp
KL2
. The colors
'red'
and
'brown'
next to the clamp are usually used by
Märklin-Motorola
systems
(e.g.
Märklin-Digital~ / Märklin Systems / Intellibox DiCoStation /
EasyControl)
.
Lenz-Digital systems
are using the letters
'J'
and
'K'
.
In case you assemble the decoder to an
Arnold-Digital (old)-
or
Märklin-Digital=
system, you have to connect
'black'
to
'K'
and
'red'
to
'J'
.
The decoder receives the
power supply
via the two poles clamp
KL1
.
The voltage shall be in a range of 14...18V~ (alternate voltage output of
a model rail road transformer).
If you do
not
want to supply voltage
separately from a transformer
to
the
LS-DEC decoder
you can
shorten
the clamp
KL1 and KL2
with two
wires. In this case the decoder will get the power supply
completely
from
the
digital network.
Connecting the signals:
General:
Up to
4 signals
can be connected to the
Light-Signal Decoder LS-DEC
.
Two signals per each 11poles clamp block
. The build-up of the two
clamps is identical. The following description refers mainly to one clamp
only. As you can see on the identical marking the description is also valid
for the second clamp.
Common connection:
All LED-signals of any manufacturer are designed in accordance to the
same principle. One wire of all light emitting diodes of a signal will be
generally connected to a common cable. Depending if all anodes or all
cathodes are connected together the signals will be called as
common
anodes-
respectively
common cathodes-signal.
If you use signals with
common anodes
(e.g. supplied from Viessmann
or alphamodell) you have to clamp the cable to the connection marked
'+'
. In addition you shall
not insert
the
connection plug bridge in J1
in
this case.
If you use signals with
common cathodes
you have to clamp this cable
to the connection marked
'-'
. In addition you shall
insert
the
connection
plug bridge in J1
in this case.
The second connection of each light diode is separated and mostly color
marked at the end and contains a series resistor.
Series resistor:
Light diodes
have
always
to be
operated
with a suitable
series
resistor
to prevent
that they will be destroyed. For this prevention
all
outputs
have already a
series resistor
of
330 Ohm
integrated
on the
printed circuit board of the
Light-Signal Decoder LS-DEC.
Is there no
further external resistor the diode-current will be about 10 mA.
This provides
sufficient brightness
.
For assigning the
single cables
of the light diodes
to the
correct
clamp
connection
please attend to the below
signal images
. The
marks
next to
signal light diodes
are not corresponding to the actual
light color but to the marking of the
connection at the Light-Signal
Decoder LS-DEC.
If you do not know the correct allocation of the single wires to the light
emitting diodes you can
test
the function by connecting the wires to
clamp RT1
. This output is
active
because the decoder switches
all
signals to red after switching on
.
