Sorting Out Decoder Difficulties
If you have any difficulties operating your Tsunami2 Digital Sound Decoder, refer to this section
first before doing anything else. We find that most problems are caused by errant CV values
and can be easily corrected. If you are unable to locate the CV that is causing the problem, try
resetting the CV values back to their defaults. Refer to “Resetting CVs and Starting Over” in the
“Introduction to Programming” section for more information.
The locomotive was running, but isn’t anymore
The decoder’s address has been accidentally changed.
CV 19 (Consist Address) has been inadvertently set.
CV 29 (Configuration Data 1) has been programmed to select other address.
CV 3 (Baseline Acceleration Rate) and/or CV 4 (Baseline Deceleration Rate) have been
set to values that are too high.
Broken motor wire or track pickup wire.
Tip: Check the decoder’s pilot light to confirm that track power is present.
The locomotive isn’t running, and never has
Refer to the information above.
The decoder has been wired incorrectly.
The locomotive is running, but isn’t producing sound
The mute function (F8 by default) is turned on.
Another function has been remapped to the mute function.
Volume control CVs (CVs 128-160) have been set to zero.
The speaker wire is broken.
The speaker is burned-out.
The locomotive is running in a consist, but without sound and lighting
The consist functions are disabled. Refer to “Consist Function Enable” under the section
“Configuring for Advanced Consist Operation” to set functions for consist operation.
The lights are flickering on and off
The decoder is set to 14 speed-step mode, while the command station is set to 28 or
128 speed-step mode.
The lights aren’t working
The decoder is set to 28 or 128 speed-step mode, while the command station is set to
14 speed-step mode.
The function mapping CVs have been improperly configured.
Lightbulbs are burned-out.
If you’re using 1.5 volt micro-bulbs, the resistor value is too large.
The lamp wires are broken.
