Page 5: Getting Started
Distribution of the booster current In order to utilise the current of 5 A that the B-4 can provide, even with smaller nominal sizes, a power splitter** can be used. The power splitter distributes the current, e.g. to two booster sections with 2 A each. -

Page 7: Intended Use
Booster B-4 1.3. Intended use The booster B-4 is intended for use in digital model railway layouts as specified in the instructions. Any other use is not in accordance with the intended use and will result in the loss of the warranty claim. Intended use also includes reading, understanding and following all parts of the instructions. -

2.1. Track voltage The Booster B-4 can provide 2 to 5 A of current at the track output, depending on the setting. The maximum output current set for the booster is identical to the cut-off current, when reached, the layout is switched off for safety reasons (e.g. -
Page 9: Anzeigen Und Bedienung
In addition, the current CV settings of the booster can be read and shown on the display. Switching on and off with a DCC turnout command The track voltage at the output of the B-4 can be switched on and off via DCC turnout setting commands sent to an assigned turnout address. -

→Background information: Selecting the power supply on page 6 Track connection The B-4 provides a regulated, symmetrical track voltage that can be adjusted in 1 V steps to a value between 10 and 24 V. This makes it ideal for use with layouts of different nominal sizes. -
Page 11: Background Information: Output Signal
The Booster B-4 is multi-protocol capable, it can transmit data (via both the DCC compliant and LocoNet interfaces) in the following formats: Motorola I and II m³ and mfx: The B-4 transmits control commands in m³ and mfx format, but no mfx feedback. Your B-4 | 11... -
Page 12: Railcom
With non-RailCom-capable DCC sound decoders, the sound reproduction can be disturbed. Therefore, the B-4 offers the possibility to switch RailCom on or off (RailCom is switched on in the delivery state). In the case of pure Motorola central units, interference with data transmission through the RailCom cutout is excluded due to the principle. -
Page 13: Switching Off In Case Of Overtemperature
Short-circuit warning The B-4 can send a short-circuit warning when a limit value below the set cut-off current is exceeded. This can be used as the basis for a PC-controlled booster management system. If there is a risk of a short circuit due to overloading, the PC control system can then switch off the carriage lighting in the overloaded booster circuit, for example. -
Page 14: Conception Of The Digital Layout
Booster B-4 tams elektronik 3. Conception of the digital layout 3.1. Dividing the layout Divide your layout into individual, electrically separate sections (booster circuits), each supplied with its own booster. A maximum of three to five locomotives should run in each booster circuit at the same time. -
Page 15: Supply With Several Boosters
Booster B-4 Cut the transitions between the booster circuits. Make sure that the sectioning points are permanently isolated! For 2-conductor layouts: one rail. Make sure that you cut the same rail (‘left’ or ‘right’) in all booster circuits. In larger, unclear systems, it is recommended to cut both rails. - Page 16 Booster B-4 tams elektronik Equalising currents and double track voltage When crossing the separation points, equalising currents occur between the (briefly differently polarised) booster circuits, even when using identical boosters from the same manufacturer. These currents are harmless for rails and vehicles and do not affect the operation.
-
Page 17: Tip: Detecting Equalising Currents
Booster B-4 Tip: Detecting equalising currents The question of whether or not dangerous equalising currents occur at a booster separation point can be detected relatively easily with the help of a model railway incandescent lamp connected to the rails or the centre conductors across the separation point. -

5.1. Programming on main (POM) 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. -

Maximum track current (cut-off current in case of short circuit) The idea of using the current of 5 A, which the Booster B-4 can provide, to supply large sections or even the complete layout is obvious. This solution, which at first glance appears to be cost-effective, promises minimised installation effort and avoids problems that can arise when crossing separation points between booster circuits. -

LED lighting up red continuously. After a short circuit, the B-4 automatically switches back on after 4 to 10 seconds. If the short circuit is still present, it switches off immediately. In the delivery state, the automatic switch- on is interrupted for one minute after the booster has switched on and off five times. -
Page 30: Reset
To reset all CV settings to the factory settings (default values), you must perform a reset using main track programming (POM) (→ Section 5.1., input value for CV 7: 8). Please note: After a reset, the ‘LocoNet’ version of the B-4 also sets the default values and not the LocoNet settings. -
