Trix BR 798 Bedienungsanleitung Seite 7

Function
• Built-in electronic circuit for operation with a conventio-
nal DC power pack (max. ±12 volts), Trix Systems, Trix
Selectrix or NMRA DCC digital systems.
• Automatic system recognition between digital and
analog operation.
• No automatic system recognition between Selectrix (SX)
and DCC.
• The full range of functions is only available under Trix
Systems and under DCC.
• Headlights for the locomotive change over with the
direction of travel. They can be turned on and off in
digital operation.
Notes on operation with direct current
• A filtered direct voltage is required for operation.Ope-
rating systems with pulse duration control are therefore
unsuitable.
Notes on digital operation:
• The first time the locomotive is used in a digital system
(Selectrix or DCC), the decoder must be set for this di-
gital system. To do this, the decoder must be program-
med once in this digital system (Example: changing an
address).
• The operating instructions for your central unit will give
you exact procedures for setting the different param-
eters.
• The values set at the factory were selected to guarantee
the best possible running characteristics.
• This locomotive comes from the factory programmed
for the digital address „01" (Selectrix) / „03" (DCC)
Number of speed levels that have been set: 28 (DCC)
and 31 (Selectrix).
• Correct programming with the 66920 Mobile Station is
possible starting with version number 034.
• Information about DCC Operation:
The setting done at the factory does not permit opera-
tion with opposite polarity DC power in the braking
block. If you want this characteristic, you must do with-
out conventional DC power operation (CV29 / Bit 2 = 0).
Safety Information
• This locomotive is only to be used with the operating
system it is designed for.
• This locomotive must not be supplied with power simul-
taneously by more than one power source.
