Conventional AC Operation
When using conventional AC power, the engine will respond to changes in track
voltage. An increase in track voltage will increase the locomotive speed and a
reduction in track voltage will reduce the engine speed.
A short interruption (approximately 1 to 2 seconds) in the track voltage will cause the
engine to cycle in the sequence for each track voltage interruption (neutral – forward –
neutral – reverse) 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
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 8 (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.
