LC SERIES DIGITAL SOUND DECODER OWNER’S MANUAL 13
1/4W resistor is recommended for use with SoundTraxx PN 810022 or 810024 microbulbs, how-
ever, you may need to adjust the resistance value to get the desired brightness depending on the
output voltage of the command station. Lower resistance will increase the brightness of the lamp.
1. To wire the Headlight, connect one end of the bulb to the decoder’s WHITE wire. Wire
the other bulb lead to the decoder’s BLUE wire.
2. To wire the Backup light, connect one end of the bulb to the decoder’s YELLOW wire.
Wire the other bulb lead to the decoder’s BLUE wire.
Any outputs not used can be left disconnected, but you should cut off and insulate the ends of
the wires so they do not come in contact with locomotive or locomotive wiring.
Step 9. Test the Installation
Now you are ready for the test track! We recommend your test track be fused with a fast-blo fuse
appropriately rated for your decoder (i.e. 1 amp decoder, 1 amp fuse). Place the locomotive on
the track, and turn on power to the system. Set your controller for locomotive address 3.
You should be able to run the engine in both directions as well as turn the lights on and off with
the function keys. You should also hear the steam airpumps running or the diesel engine rpms
idling,
If the locomotive does not travel in the appropriate direction, you have reversed the polarity of
the motor brush connection. Turn the power off, switch the ORANGE and GRAY motor leads and
try again. If everything seems OK at this point, it is time to program the decoder’s Configuration
Variables to get the desired sound and lighting effects.
CAUTION: The DSD-LC Series of decoders are designed to work at
track voltages between 7.5 and 16 volts maximum. On most command
stations, this corresponds to a track setting of N or HO. Do NOT use
the O or G scale settings!
Operating your DSD-LC at voltages greater than 16 volts will void your
warranty, produce excessive heat and possible permanent damage to
the DSD.
