Decoders (Quantum, Quantum Titan, or
Quantum Titan with ET)
Stage One: Disconnect
Double-press the
F9
key in
Neutral
to enter
Disconnect
. You will hear a
Long Air Let-off
. To leave
Disconnect
,
either double-press the
F6
Start Up
key, as described in
Start Up
(Section 4.1.9), or double-press the
F9
key
again to reach the next stage of
Shut Down
:
Standby
.
If you double-press the
F9
key in
Neutral
, the model’s electric motor drive will act as if it were disconnected. Once
you hear the
Long Air Let-off
, the DCC throttle can be moved up and down without the locomotive moving. As the
throttle is moved up or down, you will hear the sound of the
Prime Mover
in the locomotive rev up and down in
proportion to the throttle setting.
Note
:
You can also turn on the
Dynamic Brakes
(see description of
Dynamic Brakes
in Section 4.1.7) in the
Disconnect
state to create
Sound–of-Power
as the throttle is moved up and down. Engineers on prototype diesels
use the Dynamic Brakes to load the diesel motor-generator to test its output and efficiency while the locomotive
remains stationary.
Stage Two: Standby
While in
Disconnect
, quickly press the
F9
key twice to enter
Standby
. You will hear a
Long Air Let-off
followed by
a special
Low Idle
sound. The
Directional Lighting
system and optional
Ditch Lights
or
Mars Light
will shut down.
The model’s electric motor will remain disconnected, while the
Air Pumps
, automatic
Cooling Fan
operation,
Number Board Lights
(only if illuminated separately from the
Headlight
), and optional
Cab Lights
will continue to
operate. In
Standby
, the locomotive will not respond to the throttle or to most of the function keys
47
. The three
exceptions are the
F6
Start Up
function key (Section 4.1.9), the
F8
Mute
key (Section 4.1.12), and the
F10
Status
key (Section 4.1.15).
To leave
Standby
, either double-press the
F6
Start Up
key, as described in the Start Up section (4.1.9 ), or
double-press the
F9
key again to reach the final stage of the
Shut Down
process, which is called
Total Shut
Down
.
Note
:
Standby
is ideal for leaving your locomotive running on a siding. Besides hearing the low idle
Prime Mover
sounds, the locomotive will not respond if you accidentally change the throttle setting or press a function key.
Stage Three: Total Shut Down
If you double-press the
F9
key while you are in
Standby
, you will enter
Total Shut Down
. As the locomotive goes
into
Total Shut Down
, you will hear a
Long Air Let-off
. To leave
Total Shut Down
, double-press the
F6
key.
If you double-press the
F9
key while in
Standby
, you will hear a
Long Air Let-off
, after which the locomotive will
advance to
Total Shut Down
. The
Air Pump
will turn off, followed by the
Number Boards
turning off, the sounds of
the
Cooling Fans
shutting off, the
Louvers
closing, the
Prime Mover
shutting down, and, finally, the
Cab Lights
shutting off. A few seconds later, you will hear the engineer’s door open and then shut. In
Total Shut Down
, the
locomotive will not respond to the throttle or to the function keys. The two exceptions are the
F6
Start Up
Function
key (described in Section 4.1.9) and the
F10
Status key (described below).
Persistence of Shut Down Stage
If DCC track power is turned off at any stage of
Shut Down
(
Disconnec
t,
Standby
or
Total Shut Down
) or during a
Shut Down
procedure, the locomotive will remember the last
Shut Down
stage in which it was just prior to the
power going off, and the locomotive will power up in the same stage of
Shut Down
. If
Start Up
is initiated during
any of the above
Shut Down
procedures,
Shut Down
will be aborted, and the locomotive will return to normal
operation.
Note:
Total Shut Down
allows the operator to take the locomotive “off line” (turn off sounds, lights, ignore throttle
settings and function key commands) independent of the operating session; that is, the locomotive will still be “off
line” when power is reapplied for the next operating session.
47
Pressing function keys other than the three keys listed under the description of Stage Two will produce only a
Short Air Let-off
.
