Your new locomotive is pre-programmed at the
factory
to use Regulated Throttle
Control
(RTC)
in Analog (DC powered) operation. RTC makes your
locomotive operate as
though it has the mass and inertia of a prototype
locomotive.
As
a result,
your engine will resist starting up too quickly
if
at rest and will resist changes in speed once moving
(see
Standard Throttle Control™
(STC™) and
Regulated Throttle Control™
(RTC™) on
page
4).
It takes a little practice
to learn to
move
the
throttle slowly and wait until the locomotive responds
.
If you prefer that your
locomotive
respond almost
immediately
to throttle movements on your DC power pack,
it
may be reprogrammed to use Standard Throttle Control
(STC).
The
example
at the bottom of page
6
in the Owners Manual explains how to program your locomotive to use
STC.

Continue
4
to
turn
up the throttle
voltage
until the
locomotive
starts
to
move
Forward
(this
voltage
is called
V-Start
5
).
The
diesel motor(s) sounds will rev up with labored
sounds proportional to
the engine's
acceleration
and loading
(see
OSI Sound of
Power™ on page
4) and
the
locomotive
will slowly start to move
.
The
Headlight will
switch on bright
and
the optional Mars light will begin to pulse.
•
As you
slow
the engine down by gradually
reducing
the throttle
to a little
below V-start,
the diesel motor(s) rev and
labored
sounds volume decreases
,
while squealing brake
sounds occur
as
the diesel locomotive comes to
a
slow stop
6
•
If you need to turn your throttle up quite high to start your diesel
locomotive,
V-Start
can
be
adjusted for operation with your particular
DC
power pack
(see
Analog Programming on pages 6-
8). For
recommended
power packs, consult the
Quantum Analog Reference Manual
(Version
3)
available at
www.walthers.com.
Doppler Effect
This effect changes the horn pitch and engine sounds as
the
locomotive passes.
•
While the engine is moving toward the observer, flip the direction switch to turn on the
horn
.
•
Wait
at
least
one second while the horn is blowing.
•
Flip the direction switch back and forth quickly
so
the horn does not shut off
.
You will
hear the horn and other diesel locomotive
engine sounds shift
in pitch
as the
locomotive
passes by.
•
Either flip the direction switch back to shut off the horn, or continue with
long
or
short
horn operations. When you are finished blowing the horn
,
the engine
sounds
will
automatically
return to
normal
after a few seconds. If the bell was
on, it
will
shut
off just
before the sounds
return
to normal.
Note:
The faster the engine is moving, the greater the Doppler shift. Below 15 smph
,
there
is
no Doppler
shift.
Neutral
In
Neutral,
the locomotive
will continue to make prototypical sounds appropriate
to
its resting
state.
•
Enter neutral by
turning the throttle down below V-Start but not off and wait tor
the locomotive to stop
7
.
The Headlight
or
Mars
light switches
to
a
steady dim and
the Reverse
Light
will
turn
off if entering
Neutral
From Reverse (NFR).
•
You
will
hear a
short
air release when the engine
stops
moving and
enters
neutral, and
a
longer
air release about three seconds later followed by air pumps and other
background
sounds.
In
addition to the pumps,
cooling
fans and
vents
will
come
on
at
random time intervals
in
neutral. After ten
seconds
the cooling fans
shut
off if they were
on when you
entered
neutral.
•
If the diesel locomotive is left
in
Neutral
From
Reverse,
special
Low Idle
state
marked
by subdued throbbing motor sounds will automatically
come
on after 30 seconds
(see
description of Low Idle in
the
section on Quantum System Sounds on page 15)
.
The
diesel
locomotive
will
return
to normal diesel motor
sounds
when the throttle is turned
up.
•
After
the pumps
start,
you
can
also
use the direction
switch
to blow the horn
or
turn on
or
off
the bell
8
.
If
you cannot enter
neutral,
or have difficulties
with
any of the operations, you
may
need to
program your
locomotive for
optimal
use with
your
particular power pack
(see
Analog
Programming
in
next
section).
'It
is
not
necessary
to
wait for
the
engine
start
up to
finish
before
entering
forward.
If
you
tum
up the
throttle,
the
start
up
sounds
terminate
and
the diesel
locomotive will immediately
gointo
normal forward
operation.
