Stillstand abzubremsen. Der Stoppabschnitt dient
dazu, den Zug durch einen stromlosen Abschnitt auf
jeden Fall zum Stehen zu bringen, falls er wegen
zu hoher Geschwindigkeit oder zu lang eingestellter
Bremsverzögerung den Bremsabschnitt überfahren
hat.
Sie können den Stoppabschnitt auch gezielt einset-
zen, um Züge an einem genau festgelegten Punkt
anzuhalten. Der Nachteil ist jedoch, dass dabei die
Stirnbeleuchtung der Lok – wegen der fehlenden
Stromzuführung – erlischt.
Stellen Sie das Signal auf „Fahrt", schaltet das
Digital-Bremsmodul wieder auf die digitale Fahr-
information zurück und der Zug setzt seine Fahrt
fort.

Erkennung der Fahrzeuge

Das Digital-Bremsmodul erkennt alle Fahrzeuge, die
mindestens 3 mA Strom aufnehmen. Das entspricht
einem Widerstand von maximal 5 kOhm. Bei einem
geschobenen Zug, z. B. einem Wendezug, sollten Sie
das erste Fahrzeug mit einem Schleifer ausrüsten
und einen 4,7 kOhm-Widerstand einbauen, falls es
nicht über andere Verbraucher, wie z. B. eine Stirn-
oder Innenbeleuchtung verfügt.

Important notice!

Before installing and using this product please read
this manual carefully!
The Viessmann digital brake module is designed
for model train layouts operated with a Maerklin-
Motorola digital system and is only to be used in dry
spaces. The permitted maximum current is 2 A.
Any other use beyond the above is considered as
inappropriate. No liability is accepted for defects or
damages resulting from inappropriate use; such risk
is the full responsibility of the user.
! Please note!
Only use model railroard transformers
compliant with the regulations of VDE / EN.
Installation and electrical connection
must be carried out while the supply
voltage is disconnected!
Characteristics
The Viessmann digital brake module 5232 is
designed for use with a Maerklin-Motorola digital
system. It serves to stop trains in front of a signal
showing a "stop" aspect.
The brake section works like this: whenever the
signal shows "stop", the digital voltage is replaced
by DC, slowing down the train until it stops. The
electronic circuitry also assures that there is no
short circuit between DC and digital supply when
an engine enters the brake sector.
Important: Not all decoders for Maerklin-Motorola
detect the brake mode (e.g. the Maerklin decoder
c80). In some decoders this feature has to be acti-
vated by programming! Please refer to the manual
of your mobile decoder to ascertain if the brake
mode is supported.
Setting up the brake sector
The brake sector is a stretch of isolated track
ahead of a main signal and is in fact controlled by
the signal. One contact (opening the circuit) on the
signal is all you need such as is available on the new
Maerklin daylight-signals and semaphore signals.
The brake sector consists of two or three isolated
sectors (insulated centre contacts).
The first sector is for "normal running", after that
comes the "brake sector" and finally in front of the
signal is the "stop sector" (refer to figures 1 and 2).
Wiring the Digital Braking Module
The red and brown sockets of the brake module are
wired to the corresponding sockets of the central
unit or a booster. The socket "S" is wired to the stop
sector (figure 1) or to the signal contact for switching
the track supply (figure 2). The digital brake module
detects the signal aspect via socket "S". "F" is wired
to the normal running sector and "B" to the "brake
sector". All three sectors have to be isolated from
each other by putting some insulating tabs between
the connectors of the centre track supply (figures 1
and 2 - insulations marked by triangles).
Use paper for Maerklin M-track and the Maerklin
insulating tabs 7522 for K-track respectively 74030
for C-track.
IMPORTANT: If you operate trains with several
electrically connected centre pick-ups (e.g. ICE train
or push-pull operation), then the "running sector" has
to be long enough to assure that all centre pick-up
contacts are with the sector, before the first pick-up
contact reaches the "brake sector". Otherwise there
will be a short circuit.
If the "running sector" is shorter than the longest train
with illuminated coaches, then you have to install the
Märklin „pick-up-ski lifter" 385550 (M-track), 385580
