Function Mapping

The functions F0 – F16 can be mapped freely be means of
CV 33 – 50
(PAR 061 – 078).
When doing this, note the table on Page 19.
Examples for function mapping:
AUX2 is to be controlled at F5
-> Program CV 39 (PAR 067) to Value 1
LR, LV and the switching range are to be controlled at F7
-> Program CV 41 (PAR 069) to the value (64 + 32 + 16) = 112

Braking Section (CV 27)

The following possibilities can be set for activating braking
sections:
Bit 0: Braking with asymmetrical digital voltage in the left rail
Bit 1: Braking with asymmetrical digital voltage in the right
rail
Bit 4: Braking with opposed polarity DC voltage
Bit 5: Braking with equal polarity DC voltage
Bit 6: Braking with a diode in the right rail
Bit 7: Braking with a diode in the left rail
Additional adjustments to a braking section can be program-
med with CV 121 (PAR 021), CV 122 (PAR 022), and CV 123 (AR
023). When doing this, note the CV table starting on Page 16.

Error Memory

The decoder recognizes too high a current consumption or
too high temperatures and archives a corresponding value
in CV 30 / PAR 030. The decoder shows this with blinking
headlights until the error memory is overwritten by any
value. An error thus becomes visible if it occurs in a part of
the layout not visible.
Bit 0 Value 1 Excess temperature
Bit 1 Value 2 Excess current, motor
Bit 2 Value 4 Excess current, function outputs
Bit 3 Value 8 Short circuit of motor versus track
Bit 7 Value 128 Misc. motor errors (ex. blockage)

Temperature Sensor

The built-in temperature sensor works in a measurement
range of 0° – 85° C / 32° - 185° F. The sensor must be calibra-
ted once in order to enable correct function. To do this, let
the locomotive with the decoder stand for about 20 minutes
until the decoder has accepted the environment tempera-
ture and has set the current surrounding temperature in °C
in conjunction with CV137 (PAR 117).
When overwriting the temperature set in CV 118 (PAR 138),
the locomotive will come to a halt and will not go further
with the speed set until it has cooled off accordingly. In
addition, Value 1 will be set in the error memory in Bit 0.
