3.2.2 Wiring diagram
Figures and 9 show the general wiring layout for
LokSoundXL decoders:
The left terminal strip (No. 1) contains all connections
required for running and sound. The right terminal
strip (No. 2) is solely for auxiliary function outputs.
Please make sure you do not confuse the
terminals. Wrong wiring may cause damage or
destruction of the decoder – despite the
protective circuitry!
Connect the right wheel pick-up to terminal 1-1 and
the left one to terminal 1-2. Terminals 1-3, 1-4 and 1-
6 are reserved for the motor. For DC and coreless
motors only terminals 1-3 and 1-6 are used. Details
are described in chapter 3.2.3.1 and 3.2.3.2
A wheel sensor can be wired to terminals 1-4 and 1-
5. Details are explained in chapter 3.2.6.1
The speaker is to be connected to terminals 1-8 and
1-9. Installation of the speaker is explained in chapter
3.2.4. Terminal strip 2 serves for the wiring of
headlights and auxiliary functions only.
Please note, that the common of all outputs is
terminal 2-9 (positive voltage). Details are
explained in chapter 3.2.5.2 and 3.2.5.3.
3.2.3.1 Connecting a DC- or coreless motor
According to the general wiring diagram on page 11.
Please note, that any suppression chokes should remain
in the motor leads. The parameters for load control
vary depending on the type of motor (Bühler, Mabuchi,
Faulhaber) and have to be adjusted accordingly. Also
refer to chapter 5.2.1
When wiring the motor, please note that terminals 1-
3 and 1-6 are used (the ones in between remain
disconnected)!
3.2.3.2 Connecting an alternating current
(with field coils)
To simplify the modification of older I gauge models
with universal motors (with field coils) the motor can
be wired straight to the LokSoundXL decoder:
The field coil is wired to the terminals 1-3 and 1-6.
Swapping the terminals results in change of direction.
The suppressor choke remains with one contact on
the motor terminal. The other lead is wired to termi-
nal 1-4 of the decoder. As soon as a universal motor
is connected to LokSoundXL, load control is
automatically switched off. Universal motors are not
suitable for load control.
3.2.4 Installing the speaker
You may only use the specially adapted speakers (1
Watt, 32 Ohm) provided by ESU electronic solutions
ulm GmbH & Co. KG for LokSoundXL decoders.
Other speakers will distort the sound and may cause
damage or destruction of the decoder.
We cannot recommend the use of speakers designed
for HO decoders either.
The appropriate location within the model is crucial
for excellent sound reproduction. A speaker without
the sound chamber will never generate excellent
sound. Therefor carefully select the space for the
speaker and the sound chamber within the model.
The speaker must be installed in such a way that the
sound waves are not unduly blocked.
