TIPS ON USING PFA FEATURES
PFA is a unique feature of Proto-Sound® that is completely controlled by the
operator. You decide how, when or if you want to utilize the feature. By
reviewing the following tips, you should find solutions or suggestions to the
various operating scenarios you might encounter when using PFA.
Tip #1:
You can escape the PFA sequence by interrupting the transformer
throttle before the man’s whistle plays in Event 1 (neutral).
Tip #2:
You can exit PFA at anytime by turning the transformer throttle Off
for 15 seconds.
Tip #3:
You do not have to be in Forward to utilize PFA. For example, if you
activate the PFA feature while in Reverse, your train will leave the station/yard
in the same direction that it arrived in.
Tip #4:
You can use PFA even if you are double-heading with another engine
regardless of whether the second engine is equipped with an PFA programmed
Proto-Sound® module. If the second engine isn’t equipped with PFA, the only
thing to remember is that you not to turn up the transformer throttle very high
when entering Reverse in Event 2. If the throttle is set too high, then the
second locomotive will begin vibrating on the track as its motors will be
turning in reverse. If your second engine is equipped with PFA, you may want
to disable the PFA when used in double-headed operations. To disable PFA,
see the section on programming RESET functions on page 20 of this manual.
Tip #5:
You can leave any of the event stages at any time by simply
interrupting the transformer throttle. Any sound effects programmed to play in
that event will simply not occur. The only exceptions are Event 1 and Event 4.
In Event 1, interrupting the throttle has no effect on PFA until after the man’s
whistle has completed and the passenger car doors have opened. In Event 4,
you cannot interrupt PFA until after the engine begins to move. Interrupting
the throttle before the engine begins to move has no effect on the locomotive’s
operation.
