Important: All of the Märklin central
units with the Motorola transmission
format can be used to run this loco-
motive. The full range of functions is
only available with the 6021 Control
Unit 6021. Functions f1 through f4
cannot be activated if you are using
the earlier Central Unit 6020 or a
similar version. The indicator for
direction of travel is also not present
on these units.
The coding switches on the back of
the 6021 Control Unit must be set as
follows for trouble free operation:

Operating the locomotive with the
6021 Control Unit:
Entering the locomotive address.
Turning the speed control knob to
the right to the stop increases the
locomotive’s speed. Turning the
speed control knob to the left to the
"0” setting decreases the locomoti-
ve’s speed.
Important: There will be a delay in the
locomotive’s reaction to each change
in speed, depending on how you have
set the acceleration/braking delay.
Turning the speed control knob to
the left past the “0” setting: Reverses
the locomotive’s direction of travel.
Important: On the 6021 Control Unit
two arrows to the right of the
address display indicate the direction
of travel for the locomotive.
Arrow pointing up:
Locomotive runs forward.
Arrow pointing down:
Locomotive runs in reverse.
Pressing the “function” button:
Turns the headlights on.
Pressing the “off” button:
Turns the headlights off.
Pressing button: “f4”:
The TELEX couplers front and rear
are turned on. Pressing button “f4”
again turns the TELEX couplers off.
Important:
The TELEX couplers should not be
left on continuously because there is
a danger of overheating the coupler
solenoids. For that reason they are
protected with a circuit against being
on too long. Please accustom your-
self to turning the TELEX couplers on
only as long as necessary.
