Auxiliary Function Outputs - Esu LokSound User Manual

Connecting the speaker / headlights / auxiliary functions
Please handle speakers with extreme care: don't
apply pressure or touch the membrane! The
speaker's magnets are very powerful! Keep all
metal items away and secure the speaker firmly
when soldering.
Connect the speaker to the
terminals 1-8 and 1-9 of the
LokSoundXL module. Make
sure that you use a small solde-
ring iron (max. 20 W) and only
heat the marked spots as
shown in the figure (close to
the edge of the small contact
plate). Polarity
important. Make sure no solder drips on
the membrane.

Feed the speaker wires through a small hole in the
sound chamber.

3.2.5.1 Auxiliary function outputs

LokSoundXL has 8 (!) function outputs, two of which
are reserved for headlights. The remaining 6 (AUX 1
through AUX 6) can be used for lighting, smoke
generators, couplers, etc.
However, before you can use these outputs you have
to activate them as described in chapter 5.2.3.
The brightness of the outputs can be adjusted
individually in 15 steps for each output. Each function
output can also be programmed to provide certain
lighting effects (blinking, etc.).

is not
An optimal sound effect is
achieved by putting the
speaker into a sound chamber,
which is supplied with the
speaker. This will increase the
sound pressure and channel the
direction of sound. Without
sound chamber the sound
effect may be unsatisfactory.
3.2.5.2 Connecting headlights
Headlights and back-up lights are to be wired to ter-
minal block 2 as per figure 3.
Generally the outputs will have the full track voltage
(between 14 and 25 Volts, depending on the power
supply). Therefor you should equip your engine with
lamps suitable for that voltage. In older models the
lamps may be connected to the chassis (e.g. Märklin).
In this case you may not wire the return from the
lamp to the terminal 2-9. Thus the lamp works against
the common return (chassis).
In many models LEDs or 1.5 Volt lamps are used. They
can also be operated with LokSoundXL decoders, but
not without some preparation: use a 100 Ohm / 0.5
Watt resistor in series with each LED or 1.5 Volt lamp.
You also have to reduce the output voltage to 1,5 V
by setting the appropriate CV as per chapter 5.2.3.
When using 1.5 Volt lamps it is not sufficient to reduce
the brightness (dimming level) via the CV. Due to the
PWM-mechanism the full voltage will be applied for
short intervals. The lamps have to be replaced by others
that are suitable for 19 Volts.
3.2.5.3 Connecting auxiliary functions
The function outputs AUX 1 to AUX 6 can be used
for many different purposes, such as switching a
smoke generator, interior lights, automatic change of
headlights according to the rules of the Swiss Railways
(SBB), etc. Please note, that the outputs are intended
for resistive loads such as lamps, smoke generators,
relays, etc. The direct connection of a motor is not
recommended due to its inductive peaks. Use a relay
to switch the motor.
Each output can be wired against terminal 2-9 or
against the common return (chassis).
