Miscellaneous Featurescondition, back down on the throttle immediately.Important: Tsunami will work best in analog mode when using a highquality, electronically regulated power pack, preferably one that suppliessmooth, filtered DC power. Older rheostat style power packs and pulse powerpacks will result in erratic and unreliable operation and should not be usedwith the Tsunami sound decoder. If your power pack provides a Pulse powerswitch, leave it in the ‘Off’ position.Depending on the quality of the power pack’s track voltage, some automaticsound functions such as the grade crossing whistle may require a highersensitivity setting than needed for DCC operation to avoid continual triggeringof the sound effect.Analog Mode OptionsIn addition to CV 12 and CV 29 discussed earlier, there are four other CVsrelated to analog mode operation:Analog Function EnablesCV 13, Analog Function Enable 1CV 14, Analog Function Enable 2These CVs allow you to force a function input to the ON state wheneverTsunami switches over to analog mode. This is most useful for turning onlighting effects when running on a DC powered layout. Sound functionsmay be turned on in analog mode as well but this is less useful as they willeither run continuously or sound just once when the decoder is powered up- instead, use automatic sound functions discussed earlier to generate soundeffects.To enable any of Functions F1 thru F8, refer to Table N below and circle thenumbers corresponding to the function inputs you want to enable. Then addup the circled numbers and program this value into CV 13.Table K. Analog Function Enable 1CV#F1F2F3F4F5F6F7F8131248163264 128Similarly, to enable Function F9 thru F8 or F0, refer to Table O below andcircle the numbers corresponding to the function inputs you want turned on.Then add up the circled numbers and program this value into CV 14.Table L.

Miscellaneous FeaturesNote that when you enable a particular function input for analog modeoperation, it has the same effect as pressing the equivalent function key onyour DCC cab. Tsunami’s function mapping settings will ultimately determinewhich output or sound effect is activated by the enabled function. Assumingyou have not changed the default function mapping, then enabling the F0(f)function in analog mode will not only turn on the headlight, but the dynamosound as well.Analog Mode Motor Control ParametersCV 63, Analog Mode Motor Start VoltageCV 63 allows you to increase the voltage difference between when thedecoder first powers up and when the locomotive starts to move.Normally, Tsunami will power up in Analog mode around 5 volts or so andthe engine will begin moving around 7.5 volts. Under certain circumstancesyou may experience a condition where the decoder cycles back and forthbetween start up sounds and locomotive movement. The problem is usuallydue to a poorly regulated power pack output. The sudden increase in loaddue to the motor starting causes the track voltage to droop which in turnresets the sound decoder. By increasing the setting of CV 63, you canadjust the decoder so that when the motor starts, the track voltage will besufficiently high so that any droop that occurs will not turn off or reset thedecoder.CV 63 may be set to any value between 0 and 255 corresponding to tenths ofa volt. Thus, a setting of 23 adds 2.3 volts to Tsunami’s default start voltageof 7.5 volts.CV 64, Analog Mode Maximum Motor VoltageCV 64 allows you to set the maximum average voltage that will be appliedto the motor when operating in analog mode. This is useful for limiting alocomotive’s top speed as well as providing some margin of safety againstburning out a motor whose voltage rating may be lower than your powerpack’s maximum outputCV 64 may be set to any value between 0 and 255 corresponding to tenthsof a volt. A setting of 180 therefore sets the maximum average motor to 18.0volts.Caution: Tsunami only limits the average voltage to the motor. The peakvoltage applied to the motor will still be the same as the track voltage.OEM Steam Sound User’s Guide Page 52Return to Main User's GuideReturn to Table of Contents
