Controlling A Locomotive; Changing Speed - Märklin Central Station Bedienungsanleitung

1 = Global Settings
At present only the Motorola decoder type is available and is thus
preset.
2 = Special Options
In this menu you can set other properties on some types of decoders.
These properties relate to the handling of operating data. Here too
we recommend that you keep the values set on the decoder at the
factory. On some versions of decoders there is also a field with the
designation „RESET". If you touch this field, the decoder is reset
to the factory default settings. This also includes the locomotive
address for locomotives without mfx technology! In extreme cases it
may happen that after you have reset the decoder, the address in the
locomotive list no longer agrees with the address set in the locomo-
tive decoder.
Important! Do not confuse the reset for a locomotive decoder with
the reset for the entire Central Station. In the one situation
the locomotive decoder is reset to the factory default set-
tings. In the other situation the entire Central Station is reset
to the factory default settings.
3 = Analog Settings
In this instance the following parameters can be set for certain
decoders:
Analog mode activated: determining whether the locomotive can be
operated with analog controls.
Starting voltage: Determining the speed at minimum operating
voltage.
Maximum speed: determining the maximum speed at the maximum
running voltage
4 = Locomotive Running Characteristics Settings
In this instance the following parameters can be set for certain
decoders:
Reverse operation: Forward and reverse for the locomotive, inclu-
ding the headlights, are swapped.
Vmax: Setting the maximum speed in the highest speed level.
Vmin: Setting the speed in the lowest speed level.
Acceleration time: Setting for the acceleration delay.
Braking time: Setting for the braking delay.
Forward trim and reverse trim: Setting from a factor of 0.01 to 1.0
(1.0 = 100%), referring to the maximum speed that has been set.
This allows you to set the forward speed differently from the speed
in reverse. Example: Locomotives with tenders run much more
slowly with the tender up front (i.e. in reverse) then with the smoke
stack up front (i.e. forward). Hence, the forward trim can be set at
1.0 and the reverse trim can be set at 0.7.
5 = Motor Settings
In this instance the following parameters can be set for certain
decoders:
Motor Pulse Width Modulation (can motors with iron-free cores)
frequency: Setting for the frequency used to control the motor.
2 alternatives for setting the frequency (low or high frequency).
Tip: The high frequency is preferred for most motors.
Settings for load compensation:
Control reference: Adjustment for agreement with the feedback
values sent back from the motor.
Control parameter K: Determining the degree of control.
Control parameter I: Setting to the motor's inertia. High inertia
(motor with a large flywheel) requires a low value.
Control influence: Determines the degree of effectiveness of the
control.
Steady state characteristic for speed: Determines the distribution of
the individual speed levels (progressive, linear, regressive, etc.). The
different variations are shown in the settings menu as graphics and
they indicate the resulting speed at different speed levels. This se-
lection menu appears when you touch the arrow behind the symbol
currently shown on the screen.
Note: A locomotive should not be changed whose decoder has
been coordinated with it at the factory. This possibility for
making settings is a very complex area in which individual
parameters depend on each other in many ways. As a rule a
layperson will make the running characteristics for a locomo-
tive worse by attempting to reprogram these characteristics.
6 = Function Assignment / Mapping
This control area can be used to determine on certain decoders
which functions are active and which function buttons will be used to
control them.
7 = Sound Settings
Different parameters can be set here for particular decoders with a
built-in sound module. The most interesting setting is that for volume.
On certain decoders you can also adjust the operating sounds to the
running properties of the locomotive.
Operation Notes for the Settings Fields in the "Expanded"
Submenu
As already indicated, the individual settings fields in the submenus
depend on the different types of decoders (mfx decoders, digital
decoders with coding switches, digital decoders with external pro-
gramming, etc. Which parameter is being set can be reconstructed
easily as a rule from the text on the screen. The particular status in
for a parameter can be changed by touching the corresponding field
on the screen. Such a characteristic is either activated or deactivated
by entering or deleting a check mark, or in the case of variable set-
tings a cursor bar will appear, which can be changed with the arrow
buttons located on the left and right.
Changes involving the programming of a locomotive without mfx
technology are only registered by this locomotive when it is on a
programming track. The Central Station does not check whether the
locomotive has registered the change correctly.
If there is no contact with an mfx locomotive, this will be indicated by
an error message. No changes can then be made to the parameters.

3.3.3 Controlling a Locomotive

After a locomotive has been set up in the locomotive list, it is then
called up actively in the locomotive controller part of the Central
Station.

Changing Speed

Locomotives are controlled with the
red control knobs in the upper left (left
locomotive controller) and upper right
(right locomotive controller) corners of the
Central Station.
Turning the control knob to the right
– The locomotive runs faster
Turning the control knob to the left
– The locomotive runs slower
The current speed set for the locomo-
tive is shown on the display screen.
The number of speed levels depends
on the type of decoder used in the
locomotive.
Turning the control knob further to
the right after you have reached the
maximum speed will not change the
speed any more. The same holds true
when you turn the control knob to the
left, and you have already reached
speed level 0.
