Setting the dimming function: The dimming function is set via the
speed knob. Speed level 0 stands for minimal voltage (if lamps are
connected minimal brightness) at the output to be set and speed level
14 (250 on Märklin* Control Unit 6021) maximal voltage. Confirm your
setting by switching the function key „function“ on and off once.
Repeat the assignment of the function keys and the setting of the
dimming function for the other two function outputs. You can skip the
programming of an output that is not occuppied by switching on and off
the function key „function“ two times.
As soon as all functions are set the the lamps connected to the outputs
X4 to X6 flash flash several times. You automatically proceed to the
menu point „Setting the driving characteristics“. If you want to close
the programming mode you just disconnect the locomotive.
Setting the driving characteristics
1. Setting the driving characteristics - step 1
You get to this menu point automatically from the menu point „Setting
the address and the functions“ or by pushing the function key F3 when
entering the top menu level.
Setting the driving characteristic: First select the velocity
characteristic you want to set:
Characteristic 1: Function F4 off.
Characteristic 2: Function F4 on.
Definition of the direction of travel: Operate the speed knob and
check the actual direction of travel. Check if the direction of travel of
the locomotive corresponds to the direction of travel set at the central
unit. If the actual and the set direction do not correspond operate the
function key „F2“.
Choosing the PWM period: Next determine the PWM period
(= motor control frequency).
PWM period = 125 Hz: function F1 off.
PWM period = 1800 Hz: function F1 on.
