ACTIVATING AND TRIGGERING PASSENGER
STATION ANNOUNCEMENTS
Before PFA can be heard the feature must be activated first. Activation is
accomplished by holding down the bell button for three or more seconds as
described in the Activating and Triggering The Passenger Station Sounds
section found earlier on page 8.
Once the feature is activated, PFA will be played the next time the engine
enters the neutral position. In order for PFA to begin, power must remain
on once the engine enters the neutral position. At this point ProtoSounds
has taken over control of your engine and disabled the bell and whistle
buttons from any further operator functions. In addition, ProtoSounds has
reconfigured the way the DCRU reverse unit functions by disabling the
reverse unit state during operation of the PFA feature. This forces the
engine to leave your station in the same direction it arrived. The following
operator controlled “events” control PFA’s actions and sounds.
Event 1 (Forward)
While the locomotive is running in forward (or
reverse) PFA is activated by the operator pushing and holding the bell
button down for three or more seconds. The locomotive bell begins
chiming and can be left on or turned off without disabling PFA.
Event 2 (Neutral Before Reverse)
The operator now interrupts the
transformer throttle to stop the engine and put it into neutral. If the throttle
setting was at 14 volts or higher, ProtoSounds will play the sound of
squealing brakes as the engine comes to a stop.
I. Upon stopping of the engine, the operator must immediately turns
the throttle back on as the engine sits in
neutral. If the bell was not turned off
after activating PFA, it now turns off
automatically.
Note:
Failure to turn the throttle
back on within 3 seconds of leaving the
forward phase will disable PFA and
shutdown ProtoSounds. The next time you turn power back on your
engine will be in the RESET position. See page 6 for more
information.
