MTH SD70MAC Operating Instructions
The FYS feature does not begin even after stopping
the engine and hearing the brake sounds.
The power was not turned back on once the engine
enter the neutral state thus disabling FYS.The
transformer throttle was interrupted too quickly in
neutral thus disabling FYS. Leave the throttle on in
neutral until after the FYS arrival message plays.
The FYS sound effects occasionally repeat
themselves.
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 FYS event, it is probable that a
sound can occasionally be repeated one or more
times.
Once in FYS, the engine never goes in reverse.
So that the freight yard sound effects and operation is
as realistic as possible, Proto-Sound disables the
reverse unit state whenever FYS is enabled. This way
the engine never goes into reverse as the operator
cycles through the various FYS events.
When the engine enters FYS event 5, the bell
automatically comes on.
FYS 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.
Whenever FYS is enabled, pressing the whistle and
bell buttons has no affect.
Because FYS must control various effects in each FYS
event, the bell and whistle functions are disabled until
either the FYS events have been completed, or the
engine is shut down for 3 or more seconds.
