When power is first applied to the track, the locomotive will be silent for 1-20 seconds
and the headlight will be on, indicating the super capacitors are charging (The super
capacitors provide power to the sound system during direction changes or intermittent
drops in track power due to dirty track or on switches, when operating in conventional
mode). When the super capacitors are charged, all the lights will come on and the engine
sounds will start up. There should be no movement, as the engine is in neutral. Causing a
short interruption of track power by using the direction button on the transformer, or
by bringing the throttle to 0 volts and back again, will change the sequence to the
forward state. Then increasing the throttle will begin to move the engine forward, and
speed will increase as the throttle is advanced.
If there is another interruption in track power the sequence will change to the neutral
position again. The engine will remain in the neutral state until there is another
interruption in track power. The next interruption in track power will move the sequence
to the reverse state. The engine will now move in the reverse direction. If the power
interruption was accomplished by using the direction button and the throttle position
was not changed, the engine will run in the reverse direction at the same speed that it
was traveling in the forward position.
Subsequent interruptions in track power of 1-2 seconds will continue the sequence
rotation. If you happen to interrupt track power for longer than about 2 seconds, the
engine will begin its shut down sounds. If this occurs you can cycle the direction
sequence again to get back to the direction you wish to move and once the engine starts
moving its shut down sounds will stop playing. (SEE PAGE 12 (direction cycle phases)
In conventional AC operation the whistle sound, the bell sound, PFA sounds and other
operational functions can be accessed if your transformer has a horn/whistle button and
a bell button. By using combinations of button presses, different commands besides
blowing the whistle and ringing the bell can be initiated.
