Booster B-4 English
1. Why Boosters?
The three essential functions of boosters are:
1. Supplying the power needed for the operation of digital controlled
locomotives and points and other digital consumers.
2. Bringing the voltage to the rails, in order to make sure that all
vehicle and accessory decoders receive the digital switching and
control commands.
3. Making sure the current is switched off in case of a short-circuit on
the layout (e.g. when a vehicle derails), in order to prevent
damages at rails and vehicles.
In layouts monitored by RailCom the booster also provides the so-called
RailCom-cutout needed to transfer RailCom-feedback data.
You can measure the power consumption as follows:
1 locomotive gauge N 600 mA
1 locomotive gauge H0 800 mA
1 locomotive gauge 0 1.000 mA
wagon light 50 - 200 mA
another consumer
(such as a sound module) 100 - 300 mA
reserve for points 10% of the calculated sum of
power consumption
The Booster B-4 can provide 2 to 5 A current depending on the
settings. If your overall power demand exceeds the capacity of one
booster you have to connect additional boosters according to the
special requirements of your layout.

2. Getting started
How to use this manual
This manual gives step-by-step instructions for safe and correct
connecting of the booster, and operation. Before you start, we advise
you to read the whole manual, particularly the chapter on safety
instructions and the checklist for trouble shooting. You will then know
where to take care and how to prevent mistakes which take a lot of
effort to correct.
Keep this manual safely so that you can solve problems in the future. If
you pass the booster on to another person, please pass on the manual
with it.
Intended use
The booster B-4 is designed to be operated according to the
instructions in this manual in model building, especially in digital model
railroad layouts. Any other use is inappropriate and invalidates any
guarantees.
The booster B-4 should not be mounted by children under the age of
14.
Reading, understanding and following the instructions in this manual
are mandatory for the user.

Required materials
In order to connect the booster you need:
Wire. Recommended diameter:
for the connection to the transformer and the rails: > 1,5 mm²
for the connection to the digital control unit: > 0,25 mm²
A transformer. The recommended voltage and the minimum power
of the transformer depend on the desired settings.
Determining the transformer´s voltage
Desired track voltage Recommended transformer´s voltage
AC voltage DC voltage
10 – 12 V 12 V
desired track voltage
+ 2 V
12 – 15 V 15 V
15 – 18 V 16 V
18 – 22 V 18 V
> 22 V 20 V
Determining the transformer´s minimum power
desired track voltage x desired interrupting current
= minimum transformer´s power
Example: 18 V x 3 A = 54 VA
Please note:
Use a transformer with a nominal voltage not much higher than the
desired track voltage. The power resulting has to be dissipated as heat
by the booster otherwise. When this power is too high, the booster
overheats and switches off.

3. Safety instructions
Risk of fire
The booster is cooled by a ventilating fan to prevent overheating. Thus
be careful to allow the air to flow unhindered through the ventilation
slits at the booster´s top and back surface. If the vents are blocked
components can overheat and catch fire.
Risk of electric shock
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:
Only operate indoors in a dry environment.
Wiring should only be carried out when the booster is disconnected.
Only use low power for this device as described in this manual and
only use certified transformers.
Only connect the transformer in an authorised manner to the house
power supply.
Use adequetly thick cable for all wiring. Too thin a cable can
overheat.
If the layout is exposed to condensation, allow at least two hours for
drying out.

Data formats and ports
The B-4 is a multi protocol booster and capable of amplifying data sent
in the Motorola or the DCC format. It transmits control commands in
mfx-format as well, but no mfx feedback signals.
It can be connected either to a DCC-conforming booster port or to the
rail output of the control unit.
RailCom
The booster B-4 can provide the so-called RailCom-cutout needed to
transfer RailCom-feedback data in RailCom-monitored sections.
When using the B-4 with control units sending a DCC signal but not
compatible to RailCom, providing the RailCom-cutout can cause
malfunction. Some older DCC vehicle decoders and current decoders
(especially of US American manufacturers) which are not designed for
use with Railcom, do not react to driving commands properly with the
RailCom cutout activated. With sound decoders not compatible to
RailCom interferences in the sound playback can occur.
Thus with the B-4 it is possible to switch RailCom on or off (at delivery
RailCom is switched on). With pure Motorola control units, malfunction
due to sending the RailCom-cutout is impossible on principle.

Booster B-4 English
Using the ABC-braking method
The booster amplifies the track signal completely symmetrically. This
allows the ABC-braking method to be used in DCC-controlled layouts.
The DCC-input of the booster B-4 is isolated through an opto-coupler.
Balanced track voltage
The booster B-4 provides a regulated track voltage, which can be set to
a value between 10 and 24 V in 1 V-steps. At delivery the track voltage
is set to 18 V.
Regulating the track voltage to a constant value prevents changes in
locomotive speeds and lighting brightness, resulting from voltage
variations.
Rated size Recommended track
voltage
Value in state of delivery
Z 12 V
N and TT 14 V
H0 18 V 18 V
0, I and II 20 - 24 V
Short-circuit protection
The Booster B-4 provides an intergrated short circuit breaking in shape
of an integrated current limitation. This causes the booster to switch off
automatically when a short circuit occurs at the track output and thus
prevents damages to the booster, the tracks and the vehicles.
When the short circuit feedback line is connected to the booster port of
the control unit, the B-4 sends a feedback to the DCC control unit when
a short circuit occurs and then the control unit switches off the booster.
The short circuit sensitivity or the interrupting current, can be set to 2,
3, 4 or 5 A. In order to prevent damage effectively when a short circuit
occurs, the short circuit sensitivity should not be set too high.

Please note:
The set short circuit sensitivity should not exceed the maximum
transformer´s current. In case the maximum interrupting current is
higher than the maximum transformer´s current, the booster cannot
detect an overcurrent and thus does not switch off the current to
protect electronic components, vehicles and the tracks from damage.
Risk of fire !
Automatic switching on after a short circuit
After a short circuit the B-4 switches on automatically after 4 to 10
seconds (adjustable). If the short circuit is still there, it switches off
again immediately.
In state of delivery, the automatic switching on will be interrupted for
one minute after the booster has been switched on and off five times.
This autostarting time can be set individually:
to the set autostarting time after a short circuit (4 to 10 seconds) or
to an individual autostarting time between 0 and 90 seconds
(adjustable in 10 sec.-steps).
Page 10
tams elektronik
Booster B-4 English
Short circuit warning
As a basis for a PC controlled booster management the B-4 can send a
short circuit warning when a limiting value underneath the set
interrupting current is exceeded. The PC control can switch off carriage
lighting in an overloaded booster section then, for example, when a
short circuit due to overload is imminent.
The limiting value for the short circuit warning can be set from a value
0 to 1.0 A below the set interrupting current. The short circuit warning
is sent as in form of a second pulse periodical switching on and off in
the short circuit feedback line.
Switching off at overtemperature
When overheating the booster switches off automatically for safety
reasons. Possible causes:
Hindrance to the flow of air through the ventilation slits at the
booster´s top and back surface.
Significantly higher rated voltage of the transformer than the set
track voltage in combination with a high current consumption.
Watchdog function
With this function the control unit (usually controlled by a PC software)
sends in intervalls of 5 seconds a DCC points switching command to an
address assigned to the B-4. As soon as the B-4 does not receive these
commands any longer, it switches off automatically.
After switching on the booster the watchdog function is initially inactive.
It will be activated by sending a switching command to the assigned
points address. This allows you to run the layout without a PC control
and without deactivating the watchdog function.

5. Splitting your model railway layout
Split your model railway layout in several track sections electrically
isolating them from each other. Every section has to be supplied by a
booster of its’ own. In each section a maximum of three to five
locomotives should run at the same time. The following divisions are
useful:
station
engine sheds
the main lines (if necessary in several sections)
the branch lines (if necessary in several sections)
Make sure that section borders are not crossed too often.
Isolate the borders between the booster sections as follows:
With 2-rail systems: one rail. Be sure to isolate in all booster sections
on the same rail ("left" or "right"). In large confusing layouts it is
recommended to isolate both rails.
With 3-rail systems: the middle conductor.

Booster B-4 English
In order to connect the cables to the booster use the enclosed
connectors which are designed to screw on the cables.
Please note:
Do not block the flow of air through the ventilation slits at the booster
´s top and back surface, otherwise the booster can overheat. Risk of
fire! You should never cover the ventilation slits. When connecting the
booster be sure to keep sufficient distance to other devices, walls, and
the like.
Connecting the control unit
You can connect the connection "A" of the booster either to
the control unit´s track output (connections C and D only) or
the control unit´s DCC booster connection.
Check that the pin assignment of the control unit´s booster interface
corresponds to that of the booster.
If you want the control unit to switch off the booster when a short
circuit occurs, you have to connect the short circuit feedback line. If
you do not connect the short circuit feedback line, the booster will be
switched off automatically when a short circuit occurs and automatically
on again after a set time.
Connecting an additional booster
In order to connect another booster connect an additional cable to each
of the three connections of "A" .
Hint: Only use boosters of one type and made by one manufacturer to
avoid problems such as:
Problems with data transfer to the decoders.
Current leakage that make locomotives move by themselves when
other locomotives cross the borders between two track sections.
Short circuits when crossing sections.

English Booster B-4
Connecting the tracks
Connect the booster´s track port to both rails (with 2-rail systems) or to
one rail and the middle conductor (with 3-rail systems). These
connections should be repeated every 2-3 meters, because the
resistance at the connection points of the tracks is quite high. When
choosing too high intervals, problems with the short circuit indication or
the power supply of the vehicles may occur.
Please note:
The connection order of the rails (or the rail and the middle conductor)
to the two poles of the track port is not significant, if you haven’t
already connected a booster to your layout. If you have then please
note:
The left pole of the second booster´s track port has to be connected
to the same rail as the left pole of the booster already connected. The
same goes of course for the right pole of the boosters´track ports. In
case the connections are mixed up short circuits will occur when
vehicles cross the boundries of the track sections.
Connecting the power supply
Connect the transformer to the booster´s transformer port. The
required voltage and the minimum power of the booster depend on the
desired track voltage and the desired interrupting current. See section
"Determining the necessary transformer´s voltage" on page 5.
Please note:
You must not interchange the connections to the tracks and to the
transformer. Interchanging these connections normally causes
damages at the booster, in the worst case beyond repair.

7.1. Programming the B-4
The booster B-4 is set by programming on main (POM). This is possible
only with control units supporting this programming mode.
In order to start programming the booster, input the value "62" for
CV#7 of any DCC locomotive address. Proceed as described in the
manual of your control unit. This input has no effect on a decoder with
the chosen address, as locomotive decoders do not allow setting a
value for CV#7 (= version).
After having started the programming mode (input the value "62" for
CV#7), the LED flashes quickly with a yellow light. You can now alter
the booster´s settings by choosing CV#7 again and inputting a value
from the following list.
If you do not input a value for CV#7 within 30 seconds, the
programming mode will be switched off. After setting the value the
programming mode is ended automatically. If you want to alter further
settings, you have to start the programming mode again by inputting
the value "62" for CV#7.

9. Check list for troubleshooting
The booster is getting very hot and/or starts to smoke.
Disconnect the system from the mains immediately!
Possible reason: The connections to the track and the power supply
have been mixed up. à Alter the connections. Possibly the booster
has been damaged.
The LED at the booster does not light and the locomotives cannot be
driven.
Possible reason: The power supply has been interrupted. à Check
the connections to the power supply (transformer).
The LED flashes slowly in the colour yellow.
Possible reason: The control unit has been switched off or the
connection to the control unit has been interrupted. à Check the
control unit and the connections.
The booster switches off, the LED flashes quickly in the colour red.
Possible reason: The booster is poorly ventilated. à Ensure the
ventilation slits at the booster´s top and back surface allow the air to
flow unhindered.
Possible reason: The nominal voltage is a lot higher than the set
track voltage. The power resulting from the difference between the
real transformer´s voltage and the desired track voltage and the
taken current has to be dissipated as heat by the booster. If this
power is too high, the booster overheats and switches off due to
overtemperature. à Use a transformer with a nominal voltage
minimally higher than the set track voltage.
The LED on the booster lights alternatively red and yellow, then red
for appr. 1 minute, then alternatively red and yellow again.
Possible reason: There is a short circuit at the track output.
Therefore the booster switches off automatically and after the set
Page 25
tams elektronik
English Booster B-4
autostarting time automatically on again. In case the short circuit is
still there after autostarting, the booster switches off immediately.
This procedure is repeated five times, followed by a one minute
break. à Eliminate the short circuit.
The watchdog function is not active after switching on the booster
although it has been set active.
Possible reason: The watchdog function will only be activated after a
switching command has been sent to the assigned points address.
à Enter a switching command for the points address.
After a points switching command the booster has been switched off,
the LED flashes yellow.
Possible reason: The points address in question has been assigned to
the function "switching off by a DCC switching command". à Set
the function inactive or avoid to use the points address in question.
After a points switching command the booster has been switched off,
the LED flashes red.
Possible reason: The points address in question has been assigned to
the watchdog function, but there is no PC Control with this function
in use. à Set the function inactive or avoid to use the points
address in question.
