Safety Notes; Important Notes; Functions; Multi-Protocol Operation - LGB F7A Série Mode D'emploi

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.
• The LEDs in this item correspond to Laser Class 1 according to Standard EN 60825-1.
• 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).
• Factory-installed multiple protocol decoder (DC, DCC, mfx).
• The model is programmed with locomotive address 03 for use with the LGB Multi
Train System (DCC). The locomotive is automatically recognized in operation with
mfx.
• Mfx technology for the Mobile Station/Central Station.
Name set at the factory: F7A 5571
• Volume can be changed for the sound effects
• The operating sounds are on in analog operation.
• The functions can be activated only in parallel. Serial activation of the functions is
not possible (Please note here the instructions for your controller).

Preparation

The rear brake cylinders on the front truck are not mounted on the model in order to
guarantee trouble-free operation of this locomotive. The brake cylinders are included
with the model. If the locomotive is only going to be used for display, then the brake
cylinders can be installed. First, loosen the two screws on the side frame of the truck
and remove the side frames. Then push the cylinders into the correct position. Put the
side frames back on the model.
Mode of Operation Switch
The model has a three-position mode of operation switch on the back wall (Figure 1):
Pos. 0 locomotive stored without current
Pos. 1 everything on
Pos. 2 same as Pos. 1
Connection to the B Unit
On the back of the locomotive is a socket for connecting a B unit with a speaker. Only
the 20588 B unit can be connected here. Connecting older B units or other cars will
lead to damage.
Important during Digital Operation!
If an A unit pointed in the opposite direction (example: the classic A-B-A locomotive
combination) is coupled to this locomotive, then the direction of the second locomo-
tive must be reprogrammed. Otherwise, the locomotives will run opposite to each
other rather than in the same direction. To do this, program the register for CV 29 to
Function Value 5 on the decoder built into the model at the factory (Please note here
the instructions for your controller).
Sound
The bell and horn can be activated with the LGB sound activation magnet (17050) in-
cluded with the locomotive. The activation magnet can be clipped into place between
the ties of most LGB track sections.
The magnet is positioned to the side under the LGB logo cast into the plastic cover.
Place the magnet on one side to activate the horn when the locomotive passes over
this spot. The bell will sound when the magnet is placed on the other side.

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
