TROUBLE SHOOTING
l
Locomotive was running yesterday but today it just sits there - The headlight and
other functions are controllable but it won’t run. - This sometimes happens when you
clear a consist but for some reason the decoder misses the command. Use the DEL
LOCO button to “re-delete” the locomotive. Alternatively use programming on the
main to set CV19 to 0 (same thing as clearing the consist).
l
Head Light goes on and off as I change speed - You are operating a loco with an
older 14 step decoder in the 28 step mode and the head light is ON only in the even
speed steps.
l
The programmability of the decoders gives the modeler a lot of flexibility. However,
this can lead to some unpredictable results. Here are a few tips to get you out of
some situations:
l
Loco won’t respond -
l
Check that the short/long address bit is set correctly in the CFG variable (CV 29).
l
The loco might be in a consist - Press DEL LOCO, the locomotive number
then ENTER.
l
Make sure CV3, 4, 23, 24 are set to a small enough value to allow the loco to
accelerate at a reasonable rate
l
Loco won’t run on an analog (DC) layout - Check that the DC mode bit is set in
the CFG variable (CV 29).
