1. etting started

The instructions will help you step by step with the safe and proper installation and use of

your brake module. Before you start to put the brake module into operation, read this manual

completely, especially the safety instructions and the section on possible errors and their

elimination. You will then know what you have to pay attention to and thus avoid errors that

sometimes can only be rectified with a lot of effort.

Keep the instructions in a safe place so that you can restore functionality later in the event of

any malfunctions. If you pass the brake module on to another person, also give the

instructions with it.

1.1. Contents of the package

Turnout decoder WD-34:

1 brake module ABC-1 (item no. 49-03106-01)

1 plastic spacer

1.2. Accessories

Connection cables

The use of stranded wire is recommended for making the connections. Stranded wires consist

of several thin individual wires and are therefore more flexible than rigid wires with the same

copper cross-section. Recommended cross-sections:

for all connections: > 0.25 mm²

1.3. Intended use

The brake module is intended for use in model construction, especially in model railway

layouts, according to the specifications in the manual. 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. The brake module is not

intended to be used by children under the age of 14.

1.4. Safety instructions

Improper use and non-observance of the instructions can lead to incalculable hazards. Prevent

these dangers by carrying out the following measures:

Only use the brake module in closed, clean and dry rooms. Avoid moisture and splash water

in the environment. After condensation has formed, wait two hours for acclimatisation

before use.

Disconnect the brake module from the power supply before carrying out wiring work.

Supply the brake module only with extra-low voltage as specified in the technical data. Use

only tested and approved transformers.

Only plug the mains plugs of transformers into properly installed and fused earthed sockets.

When making electrical connections, ensure that the cable cross-section is sufficient.

Heating of the brake module during operation is normal and harmless.

Do not expose the brake module to high ambient temperatures or direct sunlight. Observe

the information on the maximum operating temperature in the technical data.

Regularly check the operational safety of the brake module, e.g. for damage to the

connection cables.

If you notice damage or if malfunctions occur, disconnect the connection to the power

supply immediately. Send the brake module in for inspection.

2. Operation overview

The ABC (Automatic Break Control) method is based on the fact that

the ABC brake module reduces either the positive or the negative part of the digital voltage

for the braking section and thus generates an asymmetrical track voltage and

the locomotive decoders detect this asymmetrical track voltage when entering an ABC

braking section and thereupon automatically reduce the driving speed with the set braking

deceleration or the set braking distance. By setting a constant braking distance, an exact

(signal) stop can be realised for all locomotives, regardless of the speed level with which

the locomotives enter the braking section.

The normally symmetrical

digital voltage is reduced on

one side in the braking

section by the ABC brake

module, by default on the

right rail as seen in the

direction of travel.

Symmetrical track voltage

at the normal section

Asymmetrical track voltage

at the ABC braking section

In principle, the braking section is only effective for one direction of travel at a time. When

travelling in the opposite direction, the locomotive does not react to the braking section.

While the locomotive is in the braking section,

the functions can be switched,

the CVs of the decoder can be changed by means of main track programming (PoM),

the direction of travel of the locomotive can be changed and thus the locomotive can be

shunted or driven out of the braking section in the opposite direction.

As soon as the braking distance is released or the locomotive leaves the braking section, it

accelerates with the set starting deceleration up to the set speed level. No short-circuits occur

when driving over the separation point between the normal section and the ABC braking

section.

In order to be able to use the ABC braking method, the booster must provide an output

voltage at the track output that is as symmetrical as possible. When using boosters that do not

provide a symmetrical voltage at the output due to their design, the locomotive decoders may

not brake reliably when entering the braking section.

3. Connections

The brake module is equipped with modular terminal blocks into which you plug and screw

the cables for connection to the rails and the switch (or a comparable circuit).

1 Normal track in front of

the braking section

(track output of the

booster

2 Switch

3 Switch

4 Braking section

Settin up the brake section

When determining the length of the braking section, take into account that the longest train

must come to a stop within the section. Cut the right rail as seen in the direction of travel at

both ends of the brake section.

Connections to the rails

Connect connections 1 and 4 of the brake module according to the illustration to the right rail

of the normal track in front of the braking section and to the right rail in the braking section

as seen in the direction of travel.

Connectin a switch

The brake module is bridged with a switch

to trigger the continuation of a train after it has stopped, or

to let a train pass without stopping.

As a switch you can use

a separate switch, if you want to (de-)activate the brake module manually

the switching output of a separate circuit (e.g. to control a signal with double coil drive).

If you want to switch the brake module together with a light signal, you must connect a relay

parallel to the green lamp / LED. With the make contact of the relay, you bridge (deactivate)

the brake module when the signal is in the "green" position.

Note:

The entire current for the train in the braking section must be transmitted via the connecting

cables to the rails and to the switch. Therefore, make sure that the cable cross-section is

sufficient and that the connecting cables to the rails and to the switch are as short as

possible in order to avoid a high voltage drop.

If you need long connection cables for the switch, the use of a remote switch (e.g. a switch

decoder) is recommended.

Fixin the brake modul

A spacer is included in the scope of delivery, which is mounted between the underside of the

brake module and the base. It prevents the diodes on the underside of the circuit board from

being accidentally damaged when the module is screwed on.

4. Checklist for troubleshooting and error correction

Warnin :

If you notice a strong heat development, immediately switch off the power supply for the

layout. Fire hazard!

Possible causes:

One or more connections are faulty. à Check the connections.

The module is defective. à Send the module in for inspection.

No reaction of the locomotive when enterin the brakin section

Possible causes:

The seperation points for the braking section are on the left rail instead of the right rail

(seen in direction of travel) or are not continuous. à Check the seperation points.

The CV-settings of the locomotive decoder are not correct. à Check the CV-settings if the

ABC-braking method is active and if the ABC-detection is inverted.

The output voltage of the booster is not symmetrical. à If possible, change the ABC

sensitivity of the decoder in the CV settings. Boosters that do not produce a symmetrical

output voltage due to their design may not be suitable for the use of the ABC braking

method.
