2. Safety instructions
Mechanical hazards
Cut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the PCB.
Visibly damaged parts can cause unpredictable danger. Do not use
damaged parts: recycle and replace them with new ones.
Electrical hazards
Touching powered, live components,
touching conducting components which are live due to malfunction,
short circuits and connecting the circuit to another voltage than
specified,
impermissibly high humidity and condensation build up
can cause serious injury due to electrical shock. Take the following
precautions to prevent this danger:
Never perform wiring on a powered module.
Assembling and mounting the kit should only be done in closed,
clean, dry rooms. Beware of humidity.
Only use low power for this module as described in this manual and
only use certified transformers.
Connect transformers and soldering irons only in approved mains
sockets installed by an authorised electrician.
Observe cable diameter requirements.
After condensation build up, allow a minimum of 2 hours for
dispersion.
Use only original spare parts if you have to repair the kit or the
ready-built module.

English LED-Control
Fire risk
Touching flammable material with a hot soldering iron can cause fire,
which can result in injury or death through burns or suffocation.
Connect your soldering iron or soldering station only when actually
needed. Always keep the soldering iron away from inflammable
materials. Use a suitable soldering iron stand. Never leave a hot
soldering iron or station unattended.
Thermal danger
A hot soldering iron or liquid solder accidentally touching your skin can
cause skin burns. As a precaution:
use a heat-resistant mat during soldering,
always put the hot soldering iron in the soldering iron stand,
point the soldering iron tip carefully when soldering, and
remove liquid solder with a thick wet rag or wet sponge from the
soldering tip.
Dangerous environments
A working area that is too small or cramped is unsuitable and can cause
accidents, fires and injury. Prevent this by working in a clean, dry room
with enough freedom of movement.

Other dangers
Children can cause any of the accidents mentioned above because they
are inattentive and not responsible enough. Children under the age of
14 should not be allowed to work with this kit or the ready-built
module.
Caution: Little children can swallow small components with
sharp edges, with fatal results! Do not allow components to reach
small children.
In schools, training centres, clubs and workshops, assembly must be
supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.

3. Safe and correct soldering
Caution: Incorrect soldering can cause dangers through fires
and heat. Avoid these dangers by reading and following the directions
given in the chapter Safety instructions.
Use a small soldering iron with max. 30 Watt. Keep the soldering tip
clean so the heat of the soldering iron is applied to the solder point
effectively.
Only use electronic tin solder with flux.
When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
Solder quickly: holding the iron on the joints longer than necessary can
destroy components and can damage copper tracks or soldering eyes.
Apply the soldering tip to the soldering spot in such a way that the
wire and the soldering eye are heated at the same time.
Simultaneously add solder (not too much). As soon as the solder
becomes liquid take it away. Hold the soldering tip at the spot for a
few seconds so that the solder flows into the joint, then remove the
soldering iron.
The joint should be held still for about 5 seconds after soldering.
To make a good soldering joint you should use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece of
cloth, a damp sponge or a piece of silicon cloth.
After soldering check (preferably with a magnifying glass) tracks for
accidental solder bridges and short circuits. This would cause faulty
operation or, in the worst case, permanent damage. You can remove
excess solder by putting a clean soldering tip on the spot. The solder
will become liquid again and flow from the soldering spot to the
soldering tip.

4. Operation overview
LED Control
Basic
On the PCB are integrated a constant current source, a rectifier and
connecting points for a bridging capacitor.
Constant current source: A transistor ensures, that during operation a
constant current of approximately 20 mA is available. This allows LEDs
to be connected directly without series resistors. They have a constant
brightness after reaching the required minimum voltage, independent
from the voltage supplied. The minimum voltage for blue and white
LEDs is approx. 4 V, for different-coloured LEDs approx. 3 V.
Rectifier: When connecting the PCB to analogue a.c. voltage or digital
voltage (so the function output of a vehicle decoder) the integrated
rectifier brings the LEDs to light in both directions of travel. When
connecting the PCB to analogue d.c. voltage an additional bridge
rectifier is required, when required that the LEDs light in both directions
of travel.
Connecting points for a bridging capacitor: Connecting a bridging
capacitor prevents the connected LEDs from flickering at short current
interruptions (e.g. when passing points). With an adequate
dimensioning of the capacitor the LEDs can also be supplied in longer
currentless sections.
Connecting LEDs
You can connect one LED or several LEDs in series to one LED
Control
Basic
. The maximum number of LEDs to be connected depends
on the voltage supplied and the fluorescent colour of the LEDs.

Connecting train rear lanterns
When using the LED Control
Basic
with the train rear lighting (ZSB-2) it is
recommended to connect each LED (train rear lantern) via a PCB to the
carriage´s back board. It is possible as well to connect several train
rear lanterns or one train rear lantern and further LEDs in series to one
LED Control
Basic
.
Driver´s cab lighting
The driver´s cab lighting is designed like the LED Control
Basic
, but is
equipped additionally with a SMD-LED. Like the LED Control
Basic
there is
integrated a LED constant current source and it is possible to connect a
bridging capacitor and an additional rectifier. It is not possible to
connect further LEDs.
The LEDs shine in the following colours:
FB-11: yellow
FB-12: pure white
FB-13: warm white

6. Connections
Preliminary work
Before mounting the PCB into the vehicle you should carry out all
required soldering:
wires for the connection to the power supply;
if required: connecting wires for external LEDs;
if required: additional bridging capacitor;
if required: additional rectifier.
While soldering avoid heating plastic parts of locomotives and
carriages. Parts might go out of shape!
Connection diagram
Connection to (analogue) a.c. voltage
When connecting the PCB to (analogue) a.c. voltage, the connections´
polarity is not relevant. The LEDs shine independently of the direction
of travel.
Page 12
tams elektronik
LED-Control English
Connection to (analogue) d.c. voltage
When connecting the PCB to (analogue) d.c. voltage, you have to
observe the connections´ polarity. The LEDs shine in one direction of
travel only when connected to (analogue) d.c. voltage. If they have to
work in both directions of travel, mount an additional bridge rectifier
(e.g. item no. 83-19100-10, not included in delivery) according to the
connection diagram.
Connection to a decoder output
Connect the connecting point X4 on the PCB to the appropriate output
of the locomotive or function decoder. Connect the connecting point X3
to the return conductor of the output or the return conductor for all
outputs.
Alternatively you can connect the connecting point X3 to the vehicle´s
housing ground. Please note that in this case the LEDs flicker due to
principle when the decoder is controlled in Motorola format.
Info: Light emitting diodes (LEDs)
When operated in the forward direction the LEDs light. They are
available in several different versions (differing in colour, size, form,
luminosity, maximum current, voltage limits). The longer lead of wired
LEDs (not with LEDs for ZSB-2) is normally the anode (positive pole).
With SMD-LEDs the cathode normally is shown by a mark on the
housing.
When using LEDs you always have to limit the current conduction (e.g.
by mounting a series resistor), otherwise they will be damaged after a
short operating duration. The LED Control
Basic
has an integrated
constant current source limiting the current at the output to 20 mA.
Thus it is possible to connect LEDs directly (without series resistor).

Connecting LEDs
You can connect one LED or several LEDs in series directly (without
series resistor) to one LED Control
Basic
. The maximum number of LEDs
you can connect to one PCB depends on the voltage supplied and the
fluorescent colour of the LEDs.
Notice: It is not possible to connect external LEDs to a driver´s cab
lighting.
Caution: The legs of a LED should not be mounted crosswise to
avoid short circuits!

The forward voltage of white and blue LEDs is approx. 4 V, differing coloured LEDs approx.
2 V.

Nominal voltage and operating voltage: The operating voltage with a.c. transformers is
approx. 1,4 times the nominal voltage given on the transformer. With d.c. power packs the
operating voltage corresponds to the given nominal voltage.

Tolerance and / or voltage fluctuations in practice often cause the calculated operating
voltage not being available. For that reason it is recommended to connect one LED less than
possible in theory.

Connect the LED(s) according
to the connection diagramm to
the connecting points X1 and
X2.
Connecting train rear lanterns:
Caution:
The LEDs shaped like train
rear lanterns have to be
mounted according to the
connection diagram! The
longer lead is not in general
the anode (+)!
Mounting the train rear lanterns
In order to fix a LED shaped like a train rear lantern safely, it is
recommended to use a PCB of its own for each LED.
Fix the PCB on the inside of the carriage´s board beside the holes
needed to feed through the legs of the LED. Take care to mount the
connecting points for the LED directly beside the holes. Bend the legs of
the LED in direction of the PCB, when fed through the hole. Shorten the
legs so that they end directly above the connecting points and then
solder them.
Page 15
tams elektronik
English LED-Control
Note: The LED should be mounted with a small distance to the back of
the carriage like in reality. Use a match as a spacer while mounting the
LED.
Info: Electrolytic capacitors
Electrolytic capacitors are often used to store energy. One of the two
leads is marked with a minus sign which indicates the mounting
orientation. The value is given on the casing.
Electrolytic capacitors are available with different voltage sustaining
capabilities and capacities. The maximum capacity only depends on the
space available for mounting the capacitor (the higher the capacity the
bigger the capacitor). Using an electrolytic capacitor with a voltage
sustaining capability higher than required is always possible.
Connecting a bridging capacitor
In order to supply the LEDs in currentless parts you can mount an
additional capacitor to the PCB. It is recommended to choose a
capacitor with a capacity as high as possible. The minimum voltage
sustaining capability of the capacitor depends on the power supply:
Power supply Voltage sustaining capability of the bridging
capacitor
< 18 V > 16 V
> 18 V > 25 V
Please note: When connecting the PCB to a decoder output intended to
be dimmed, you should not mount a bridging capacitor.
