Frequently asked questions (FAQ)

6. Frequently asked questions (FAQ)

There could be many reasons if the LokSoundXL

decoder does not work properly after installation.

Frequently there is no defect, only the various settings

do not correspond with the respective locomotive.

We list some symptoms and how to solve them:

„Lighting / sound / read and write CVs works, but

the locomotive does not move.“

•A short circuit in the motor or a high current draw

has released the overload protection of LokSoundXL

decoder.

•The motor may not be isolated from the chassis. In

this case remove the motor but do not disconnect

it and test the LokSoundXL decoder.

•Set the motor takt frequency from 22 kHz to 87

Hz when using universal motors (see CV 9).

„The locomotive jerks and does not run smoothly at

low speed when Back EMF control is activated.“

•Check if the symptoms persist when you deactivate

Back EMF control (see chapter 5.2.1). If so, adjust

the motor control parameters (see 5.2.1)

•Possibly the motor has not been isolated against

the chassis. To eliminate this particular problem first

remove the motor and then test it. If it works you

have identified the cause of the problem.

Make sure there is no electrical contact between

the motor and chassis when you reinstall the motor.

This is particularly important with older motors from

Märklin® (ie: class 78).

„The locomotive runs, but there are no sounds.“

•Check the wiring to the speaker.

•The F1 key works only with the new Motorola

format when using Märklin® 6021 (see chapter

4.2.1). If this is ok, there may be damage to the

speaker.

„I would like to reset the LokSoundXL decoder to

factory settings. How does it work?“

•This is not an easy task because the factory settings

vary depending on the purchased sound version.

However, for most CV’s, a default value is given in

• The LokSoundXL decoder changes again to

to modify.

•Exit the programming mode by selecting register

"80" or switch the track voltage off and on (press

"stop"-key and then "go"-key on 6021).

the table found in chapter 7.1

•A decoder-reset is easily possible with a PC and the

LokProgrammer software.

„After installing the LokSoundXL decoder the

locomotive moves in one direction at max speed

while it remains stationary in the opposite direction!?“

•This is caused by an incorrect motor connection.

Please refer to Fig. 2 and 4. Has the motor been

connected to the right terminals? They are not

located adjacent to each other, there may be inputs

or outputs in between.

I have installed LokSoundXL decoders in my LGB

locomotives. Why do functions F2 and higher not

respond when activated with the LGB-Lokhandy?

•This problem is typical for the LGB command station

and is not related to our decoder. If you press F5

for instance, then the Lokhandy transmits five times

F1 on, F1 off, F1 on, etc. The LGB decoders count

these pulses and subsequently switch the required

function output.

•LokSoundXL decoders can „count“ these pulses,

but you need to enable this function first. See

section 4.2.2 for further details.

„I have studied the manual, but there are still

problems. What can I do?“

•If you have further questions don't hesitate to

contact our service department. Contact details are

listed in chapter 8, on the last page of this manual.

•If you have studied this manual but feel you don't

want to proceed with the installation, esu electronic

solutions ulm GmbH can offer professional help:

Enquire at your local hobby store for the LokSound

service pack: we install the decoder for you.

of the implications. Wrong settings may damage
