ACTIVATING AND TRIGGERING FREIGHT YARD SOUNDS
Before FYS 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 Squeaking Brake Sounds
section found earlier.
Once the feature is activated, FYS will be played the
next time the engine enters the neutral position. In order for FYS 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 reverse unit functions by
disabling the reverse unit state during operation of the FYS feature. This
forces the engine to leave your freight yard in the same direction it arrived
in. The following operator controlled “events” control FYS’s actions and
sounds.
Event 1 (Forward) While the locomotive is running in forward (or
reverse) FYS 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 FYS.
Event 2 (Neural 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
squeaking brake sounds as the engine comes to a halt.
A. Upon stopping of the engine, the operator must immediately turn
the throttle back on to keep the engine in the Neutral position. If the
bell was not turned off after activating FYS, it now turns off
automatically.
Note:
Failure to turn the throttle back on within
3 seconds of leaving the Forward phase will
disable FYS and shutdown ProtoSounds®. The
next time you turn power back on your engine will
be in the RESET position. See page 4 for more
information on RESET.
