Changing direction
The locomotive's direction is reversed by turning the speed
control knob to the left past the "0" setting.
4. Short Circuit or Overload on a Transformer
A built-in thermal switch protects the Transformer from
damage in case of an overload or a short circuit. Locomo-
tives on the layout will come to a stop, accessories cannot
be operated and all lamps connected to the Transformer will
go out.
The following procedure is recommended:
1. Unplug the power cords for all transformers from their
outlets.
2. Look for the cause of the short circuit on the layout and
correct it.
3. After about 1 minute the thermal switch will go back to
being on. After this amount of time has passed, all Trans-
formers can be placed in operation again.
If the Transformer should shut off again and you are unable
to locate a short circuit, then the Transformer is overloaded.
In this case the number of users connected to the Transfor-
mer must be reduced.
Other Information
All Märklin products as delivered conform to the relevant
regulations on preventing interference with radio and televi-
sion reception. Worn out materials and/or faulty mainte-

with the instructions can lead to increased interference with
radio and television reception. An information sheet on this
subject is available on request.
The wiring diagrams that apply to the different turnouts or
signals can be found in the instructions the come with these
products.
Checking the Polarity
When two or more train control transformers for different
track circuits are used on a layout, it may happen that
different polarities for the transformers may cause a strong
spark on the pickup shoe of a locomotive passing over the
separation point between two track circuits. In this instance
the plug on the power cord for one of the transformers must
be removed from its outlet, turned 180° and plugged back
into the outlet.
