Lock-out
Solution
I can't get the engine to run after I power up
the transformer. It sits still with the diesel and
compressor sounds running.The engine won't
lock into forward, neutral, or reverse.
The engine maybe locked into the neutral
position. Follow the procedure in the "Lock into
a Direction" section to unlock the engine's direc
-
tion. Engine speed must be below 10 scale mph
(approx. 10 volts or less in conventional mode).
Volume
Solution
The sounds seem distorted, especially when the
Horn or bell is activated.
Proto-Sound® 3.0 volume is set too high. Turn
the volume control knob on the bottom of the
chassis counter-clockwise to reduce the volume.
No Sound
Volume is set too low, adjust volume control
knob on the bottom of the chassis clockwise
to increase the volume or check connector to
speaker.
PFA
Solution
Once in PFA, the engine doesn’t go into reverse. So that PFA effects can be as realistic as pos
-
sible, Proto-Sound® 3.0 disables the reversing
unit whenever PFA is enabled. This way the
engine remains still at its stop as the operator
cycles through the PFA sequences.
When the PFA enters its last sequence the bell
automatically comes on
PFA is programmed to start ringing the bell at
that point. After approximately 12 seconds, it
will automatically turn off.
When PFA is enabled, pressing the whistle and
bell has no effect
Because PFA must control various effects in
each sequence, Proto-Sound® 3.0 takes control
of these sound effects until you exit PFA
I push the direction button but the next sound
clip in the sequence does not play or the engine
does not come out of PFA after fourth press of
the direction button.
Each PFA clip must play for aprox. 30 seconds
before PFA will advance to the next step in the
PFA cycle. Wait at least 30 seconds in each
PFA sound clip before pressing the direction
button.
