Safety Notes

• This model may only be used with the operating system designed for it.
• Use only switched mode power supply units and transformers that are designed
for your local power system.
• This locomotive must never be supplied with power from more than one power
pack.
• Pay close attention to the safety notes in the instructions for your operating sys-
tem.
• Not for children under the age of 15.
• WARNING! Sharp edges and points required for operation.

Important Notes

• The operating instructions are a component part of the product and must therefore
be kept in a safe place as well as included with the product, if the latter is given to
someone else.
• The warranty card included with this product specifies the warranty conditions.
• Please see your authorized LGB dealer for repairs or spare parts.
• Disposing: www.maerklin.com/en/imprint.html

Functions

• This model is designed for operation on LGB two-rail DC systems with conventio-
nal LGB DC train controllers or power packs (DC, 0 - 24 volts).
• Power cannot be supplied via catenary.
Note: A locomotive controller with more than 3 amps of track current is required for
this model.
Buffer Beam
The buffer beam on the locomotive can be replaced by the buffer beam for a center
buffer that is included with the locomotive (Fig. 1).
• Loosen the 2 screws used to mount the buffer beam.
• Replace the buffer beam and fix in place with the 2 screws.

Multi-Protocol Operation

Analog Operation
This decoder can also be operated on analog layouts or areas of track that are
analog. The decoder recognizes alternating current (DC) and automatically adapts
to the analog track voltage. All functions that were set under mfx or DCC for analog
operation are active (see Digital Operation).
Digital Operation
The decoders are multi-protocol decoders. These decoders can be used under the
following digital protocols: mfx or DCC.
The digital protocol with the most possibilities is the highest order digital protocol.
The sequence of digital protocols in descending order is:
Priority 1: mfx; Priority 2: DCC; Priority 3: DC
Note: Digital protocols can influence each other. For trouble-free operation, we re-
commend deactivating those digital protocols not needed by using CV 50. Deactivate
unneeded digital protocols at this CV if your controller supports this function.
If two or more digital protocols are recognized in the track, the decoder automatically
takes on the highest order digital protocol, example: mfx/DCC; the decoder takes on
the mfx digital protocol (see previous table).
Note: Please note that not all functions are possible in all digital protocols. Several
settings for functions, which are supposed to be active in analog operation, can be
done under mfx and DCC.
Notes on digital operation
• The operating instructions for your central unit will give you exact procedures for
setting the different parameters.
• The values set at the factory have been selected for mfx in order to guarantee the
best possible running characteristics.
Adjustments may have to be made for other operating systems.
• The setting done at the factory does not permit operation with opposite polarity
DC power in the braking block. If you want this characteristic, you must do without
conventional DC power operation (CV 29/Bit 2 = 0).
