Important safety instructions
The function decoder LF101XF is to be used only with Lenz
DIGITAL plus or other standard digital controls with an NMRA-
conformance seal. If in doubt, ask the system supplier.
The maximum current-carrying capacity of the decoder outputs
must not be exceeded as this will destroy the decoder! The parts
of the decoder must not be allowed to touch the metal
components of the chassis or the body of the locomotive as this
will cause a short-circuit within the decoder resulting in its
destruction.
Never wrap the decoder in insulating tape as this prevents the
necessary air circulation around the decoder. Instead, use
insulating tape or something similar around the metal
components of the vehicle to avoid unintentional short-circuits
without depriving the decoder of air. Use double-sided adhesive
tape to affix the decoder.
Technical data:
Total current-carrying capacity: 0.4 A
Current-carrying capacity of the outputs: 200 mA each
Settable locomotive addresses: 1 - 9999
By default, the decoder is set as follows
(Of course, these default settings can be changed as desired):
Locomotive address: 3
Speed-step mode: 28 steps
Outputs A and B: controlled by F0, polarity-dependent
Output C: controlled by Function 3
Output D: controlled by Function 4
Output E: controlled by Function 5
Output F: controlled by Function 6

Features of the function decoder LF101XF
The LF101XF is a DCC function decoder used to control functions
in locomotives or coaches. (In analogue mode, the decoder
functions are inactive). A total of six outputs are available.
A typical application is the switching of coach lights or the
direction-dependent front light of control cars. The LF101XF has a
special drive for diode-equipped control cars. The LF101XF also
supports numerous lighting effects:
Dimming:
Setting the brightness of
bulbs or luminous diodes.
Flashing:
Individual outputs or
alternating flashing with two
outputs (ditch light). The
flashing frequency is
settable.
Marslight:
Rising and dimming of the
light, 1x:
Gyrolight:
Rising and dimming of the
light, 2x:
Strobe: Flash of light
Double strobe: Double
flash of light
The individual outputs A, B, C, D, E and F can be configured
individually have individual effects and to be controlled by various
functions of the Digital System. This allocation is carried out by
programming the CVs

Basic connection of functions
The individual functions are all connected in accordance with the
same principle: From the decoder output to one function pole, and
from the other function pole to the blue decoder wire. Alternatively,
the blue wire can be substituted by a connection to a track
connection (red or black wire).
If a track connection is used instead of the blue wire for
Outputs A and B, then CV49 must be set to polarity-
independent lighting (CV 49 = 0)!
Please note that LEDs are polarity dependent. If a function output
is to be connected to an LED, note that the function output is
negative and that the blue wire is the positive. If you want to
connect LEDs to the LF101XF, do not forget voltage limiting
resistors as the Blue wire is one volt less then full track voltage.
You can install several LF101XFs in the same vehicle or you can
use the LF101XF in the same locomotive as a locomotive
decoder. If you install multiple decoders in the same locomotive,
make sure that you program the decoders separately; before
installation.

The figure above shows the basic connection of the
functions to the LF101XF. Here, all functions are
connected to the blue wire (positive pole).
In this figure above the C and D functions outputs are connected
to the black track connection:
Installation in a control car with polarity-dependent lighting
Control cars with direction-dependent light changes are normally
designed so that in analogue mode the direction-dependent
switching of the lighting (white/red) is done automatically via the
track polarity. Depending on the track voltage polarity, the white or
red light is activated: In the forward direction the positive pole is
located on the right rail and the white light is activated. In the
reverse direction, the red light is activated.
To facilitate conversion of these types of control cars, outputs A
and B of the LF101XF are designed so that you can simply insert
the LF101XF between the wheels and the electronics of the
control car. Outputs C, D, E and F are then available for other
functions, e.g. the internal lighting of the coach. CV49 = 1 (the
default) is used to set this mode of operation.

Programming the locomotive address and the
function settings of the LF101XF
The locomotive address and all other settings of the locomotive
decoder can be changed as often as desired by PROGRAMMING.
The settings of the function decoder are ‘stored’ permanently in
several ‘storage’ locations even when the operational voltage is
switched off. In DCC parlance these locations are called
‘Configuration Variables’ or simply ‘CV’. The writing/reading of
values is done electronically; therefore it is not necessary to
reopen the locomotive after the decoder has been installed. Some
features are activated/deactivated by entering a decimal value,
others simply by setting or deleting bits in a CV. The table below
lists the meanings of bits wherever features are changed by
setting or deleting individual bits.
To program the locomotive decoder you need a command
station such as a LZ100/LZV100 with a handheld such as a
LH100, a LH90 or a computer Interface. For detailed
information on programming, please refer to the operating
manuals of the respective devices.
Resetting the decoder
If you wish to reset all the decoder CVs to the factory default
setting, enter value 33 or a value of 8 in CV 8.

Function mapping for function outputs:
To allocate a function of the Digital System to a
function output, look for the section where the
row of the desired function intersects with the
column of the desired function output. Write the
number found into the relevant CV. For
clarification, the table shows the default settings
in bold print.
Example ‘Function output C is to be activated
with function 3”. Where row CV37/Function 3
intersects with column Function output C, you
will find number 32.

If a function is to have an effect on several
function outputs, the values found at the
intersections must be added up and the result
written into the CV.
Example: Function outputs C and D are to be
switched with function 1. You must add up the
two values found at the intersections of row
CV35/Function 1 and the columns Function
output D and C and enter the result in CV35:
32+64=96.
49 Bit Polarity-dependent lighting for
outputs A and B
1 (0) 1 Outputs A and B change their polarity
depending on the direction of motion. In the
forward direction, output A is the negative
pole, in the backward direction, output B is
the negative pole.
0 Outputs A and B do not change their polarity
and act as normal functions activated by the
values in CVs 33-42.

Dimming values for function outputs A to D. An
individual value can be set for each output.
Value 255 corresponds to maximum brightness.
Technically, the brightness is set via a so-called
pulse-width control, i.e. the voltage at the
output is not reduced. This is why setting the
brightness is no adequate way of adapting to
low-volt bulbs!

Function mapping for dimming:
If value 10 is entered in the CV (no bit set), the
corresponding output is permanently dimmed. If
an allocation is entered (value greater than 0, at
least one bit set), the dimming can be
activated/deactivated with the selected function.
Each bit of the CV stands for a function of the
Digital System: Bit 1(0) for function 1, Bit 2(1) for
function 2 and so on up to Bit 8(7) for function 8.
If you want to allocate a function to the dimming,
the respective bit must be set.
