5.3.3 Using Märklin® 6021
With the Märklin® command station you cannot
modify standard CVs as it does not comply with the
NMRA DCC standards. However, the most important
CVs of LokSound decoders may be changed with a
specific programming mode. Please note this applies
only to CVs from 1 to 79, and only for values from 1
to 79.
Programming mode for 6021:
Set the drive control knob to 0. Remove any other
engines from the track. Observe the blinking signals
of the engine! Press the „stop“- and „go“ button of
the 6021 simultaneously until a reset has been
triggered. Alternately you can remove the power plug
for a moment. Press the „stop“ button in order to
switch off the track voltage. Enter the current decoder
address (alternately: 80).
•
Confirm by activating change of direction (turning
the control knob beyond the stop position towards
the left) and hold the knob, then press the „go“
button.
•
The LokSound decoder is now in programming
mode (headlights are blinking). Now enter the
number of the parameter (CV) you want to change
(two digit number).
•
Confirm by activating change of direction (double
blinking headlights).
•
Now enter the new value for the CV (2 digits).
•
Confirm by activating change of direction
(headlights light up for about 1 second, then
continue blinking).
•
Now you can continue with other CVs in the same
manner.
•
To exit the programming mode select CV 80 or
switch off the track voltage for a moment (press
„stop“ button followed by „go“ button on 6021).
Please note that 6021 only permits entries from 01
to 80. There is no value „0“, instead always enter
80.
6. Frequently asked questions (FAQ)
Usually there is no fault in the LokSound decoder if it
does not work as desired but very likely some CVs are
set incorrectly. Here are some examples of what may
happen and how to solve them:
•
Headlights and sound work, write CVs as well, but
the engine does not move.
A short circuit on the motor terminals or a high
current draw may trigger the overload protection.
Perhaps the motor is not fully insulated against the
chassis. To eliminate this as the cause of the
malfunction remove the motor and test-run it while
outside the engine.
If load control is deactivated the starting voltage may
be too low (CV 2).
• The engine jerks and runs very uneven at low speed
with activated load control.
Deactivate load control and check if the problem
remains (refer to chapter 5.2.1). If the problem
disappears then the parameters for load control have
to be adjusted (as per 5.2.1).
•
The engine runs perfectly, but there is no sound.
Check the wires to the speaker.
With the Märklin® 6021 the new Motorola format
has to be used, otherwise the F1 button does not
work (refer to chapter 4.2.1). If the format is set
correctly, the speaker may be damaged.
•
The engine runs perfectly, but the headlights do
not work or switch on and off depending on the
speed step.
If you have an engine with DCC socket check if the
plug has been inserted in the correct position (refer
to chapter 3.2).
•
If you operate LokSound in DCC mode please refer
to chapter 4.2.2 where the solution to this problem
is described.
•
I would like to reset the LokSound decoder to the
factory settings. What do I have to do?
With the aid of a PC and the LokProgrammer
software a reset is easily achieved. If you only
want to reset the CVs write value 8 in CV 8.
