PFA PROBLEMS
The PFA feature does not begin even after stopping
the engine and hearing the brake sounds.
The PFA sound effects occasionally repeat
themselves.
Once in PFA, the engine never goes in reverse.
When the engine enters PFA event 5, the bell
automatically comes on.
Whenever PFA is enabled, pressing the whistle and
bell buttons has no affect.

REMEDY
The power was not turned back on once the engine
enter the neutral state thus disabling PFA.The
transformer throttle was interrupted too quickly in
neutral thus disabling PFA. Leave the throttle on in
neutral until after the PFA arrival message plays.
Proto-Sound® has a built--in random number
generator that randomly selects each sound clip to
play. Because there are only a total of 8 sound clips
available in each PFA event, it is probable that a
sound can occasionally be repeated one or more
times.
So that the passenger station sound effects and
operation is as realistic as possible, Proto-Sound®
disables the reverse unit state whenever PFA is
enabled. This way the engine never goes into reverse
as the operator cycles through the various PFA
events.
PFA has a built--in command to turn on the bell when
the system enters Event 5. After approximately 15
rings of the bell, it automatically will turn off.
Because PFA must control various effects in each PFA
event, the bell and whistle functions are disabled until
either the PFA events have been completed, or the
engine is shut down for 3 or more seconds.
