mode. Refer to Section 16.3 for programming instructions. Additional informa-
tion about programming CV29 is available in your Digitrax Decoder Manual.
If you have a Digitrax Series 3 decoder and you can control the lights but not
the motor, check for a motor short circuit. These decoders are designed to shut-
down motor operation when a short is detected to prevent damage to the
decoder.

Did you select the locomotive’s actual address?
If you don’t know the
address of the locomotive on the track, you can read it back in programming
mode or you can reprogram it to a new address. See Section 16.6
Is the loco on powered track?
Make sure the
Track Power Indicator
on the DCS51 is on, press the
pOWer
key to turn on track power. See Section 7.2
Use the “Quarter Trick” to test for track power at several locations around the
layout. If there is not track power, check your layout wiring. See Section 27.2.1
Can you select the loco on your throttle?
Is the loco in use by another throttle did the throttle display
“
StLo
”
. If it did,
then dispatch the loco from the other throttle.
If the loco is part of an MU, the
MU Indicator Dot
will light up when you
select it. you can control the functions, but not speed and direction.
Do the settings in CV29, the configuration register, match the command
station output?
If your decoder is a 14 step decoder running on any Digitrax
system using factory settings, status editing will be needed for that decoder.
Have you reset any CVs since the last time you ran the loco?
It is possible to set acceleration so high that it will take 10 minutes for the loco
to start moving. Try resetting the CV values to their factory settings and then
running the locomotive. Remember, Digitrax uses address 03 for the factory
setting for all decoders. Check your decoder manual for factory settings and
instructions on resetting the values.
Was the loco running normally just before it stopped?
Check to make sure the decoder has not heated up and gone into a thermal
shutdown. If it is warm, remove the loco from the track, let it cool off and then
see if it starts again. Also check for localized track problems.
Are there burn marks on the decoder?
You’ll need to send it in for repair!
If all else fails, reprogram the decoder address and reset CVs to factory original
values. See your decoder manual for factory settings and reset instructions.
Does your throttle say “FuLL” ?
This means that the Zephyr Xtra system’s capacity to handle operating locos is
full. The DCS51 can run up to 20 addresses at the same time. This includes all
decoder/locomotive addresses in use on the system, whether they are being run
individually or as part of an MU. If you have the “FuLL” message, be sure that
all locos that are not running are released from throttles. If you run into this
