MTH SD40-2 Diesel Operating Manual
ProtoSounds® has been programmed to sound the horn in neutral). Turn
the throttle off and then on again to “Lock-In" your selection. Now,
whenever you are in neutral, you can blow the horn with the transformer
whistle button. To reset ProtoSounds® to its original factory setting of no
horn in neutral, repeat the above procedure but keep pressing the whistle
button in Feature 25 until ProtoSounds® only dings once instead of twice.
Note: When Whistle In Neutral" is set, the bell will only operate with a separate bell button
and the horn will not sound in neutral if the transformer throttle setting is over 11 volts. At 11
volts or higher, ProtoSounds® may arm the coil coupler for operation whenever the whistle
button is pressed and the engine is in neutral.
PROGRAMMING FOR PROTOCOUPLER OPERATION
ProtoSounds® comes with
a RESET feature that allows
the operator to remotely turn
off the ProtoCoupler™
functions. This is especially
useful when double or triple-
heading ProtoSound®
equipped engines since every
engine equipped with a
ProtoCoupler™ will fire
when prompted to by the
operator. By turning off the ProtoCoupler™ operation on certain engines,
you can fire the couplers open on the other engines without uncoupling the
engines from each other. To turn the ProtoCoupler™ function off, enter
RESET and go to Feature 10. (See the section on Using RESET To
Program ProtoSounds® on page 18.) Once in Feature 10, press the
transformer whistle button and wait for ProtoSound® to sound a bell
ding(s). Continue pressing the whistle button until ProtoSounds® sounds
two bell dings (signifying that the ProtoCoupler™ option has been turned
off). Simply turn the transformer throttle off and then on again to lock in
the new setting.
PROGRAMMING FOR SQUEAKING BRAKES AND
FYS OPERATION
ProtoSounds® is equipped with a RESET setting to turn off the Freight
Yard Proto-Effects (FYS) features. This is especially useful if you are
double-heading engines that are both equipped with FYS. You may not
