Tips on Using PSA
• You can terminate PSA at anytime by turning off power to the
track for 15 seconds.
• You do not have to be in Forward to use PSA. At the
conclusion of the full sequence, the train will pull away from the
station in whatever direction you were going when you activated
the feature.
• You can use PSA even if you are double-heading with another
engine. If the second engine is not equipped with PSA at all, you
must remember not to leave the throttle at a high voltage level
once you have stopped the engine to run the PSA. Otherwise, the
engine without PSA will begin vibrating on the track as its
motors strain to move the train, since they cannot be
automatically disabled during the PSA cycle. If the second
engine is an original Proto-Sound engine equipped with PSA,
you may choose to disable it when used in double-heading
operations, so you will not experience competing PSA sounds.
To disable PSA in an original Proto-Sound engine, see the
operating instructions for that engine.
• PSA can be triggered from Neutral. It will operate the same as
if triggered while in motion except that, at the conclusion of the
PSA, the engine will depart in the next direction of travel, as
opposed to the direction it was traveling before entering Neutral.
