rating systems with pulse duration control are therefore
unsuitable.
Notes on digital operation:
• 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 „55“
Number of speed levels that
have been set: 28.
• Correct programming with the 66920 Mobile Station is
possible starting with version number 034.
• 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
