Premier U50C Diesel Engine Operating Instructions
Tips on Using FYS
• You can terminate FYS at anytime by turning off power to the
track for 15 seconds.
• You do not have to be in Forward to use FYS. 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 FYS even if you are double-heading with another
engine. If the second engine is not equipped with FYS at all, you
must remember not to leave the throttle at a high voltage level once
you have stopped the engine to run the FYS. Otherwise, the engine
without FYS will begin vibrating on the track as its motors strain to
move the train, since they cannot be automatically disabled during
the FYS cycle. If the second engine is an original Proto-Sound
engine equipped with FYS, you may choose to disable it when used
in double-heading operations, so you will not experience
competing FYS sounds. To disable FYS in an original
Proto-Sound engine, see the operating instructions for that engine.
• FYS can be triggered from Neutral. It will operate the same as if
triggered while in motion except that, at the conclusion of the FYS,
the engine will depart in the next direction of travel, as opposed to
the direction it was traveling before entering Neutral.
