I’m trying to program the start, top, Acc, and dEc votlage for my Bachmann Loco, but I don’t know the range of variables. No info came with the loco other than the address. Can anyone help??
Also, the loco hums on initial throttle up and it’s running (what I consider to be) slow. Full throttle on this new loco and track system is way slower than my old basic DC loco and oval track system. Any suggestion would be greatly appreciated. Thanks!!
Maybe there IS no decoder in that engine? If it says “DCC ready” on the box, it means the engine is wired for an easy installation of a decoder.
The information you seek to modify CVs is in the Prodigy Express manual, not in the loco manual, as you suggest…which also leads me to conclude that it was a logical ommission when there is no decoder in the engine.
If there actually is a decoder, then you must have the throttle set for the address of the loco, or on “03” if the loco address set by the factory has not been altered by you.
Another matter might be the mode of programming. Can you loco be programmed on the main in Ops Mode? Maybe you need a programming track…and a booster?
In any event, suppose there is really a decoder. Set the address for the loco, as I describe above, and then enter programming mode of your choice. Dial in CV 2 and add a value, probably around 38. Exit programming and turn the throttle to 1. Will the loco move? If not, enter programming and set CV 2 to 44, and try it again. At some point, the loco will move off at a setting of 1 on the throttle. That is your Start Voltage.
Do the same for CVs 3 and 4 to get the acceleration time-lag and deceleration time-lag that you desire.
My BLI locos all come with CV value information, but the process for modifying those values is found in my Digitrax manual.
The Bachmann locos that come with decoders use an absolutely bargain basement Lenz decoder that has very few features. They don’t even have any form of silent drive, so they may buzz a bit. I believe it’s the LE1000, you can probably find information on it on the Lenz site.
