Automatic Features
Automatic Quantum Features depend on the directional state of the locomotive. Automatic Control can be enabled or disabled by their
indicated function keys. The state of each Automatic feature in each direction is shown in the table below.

When an indicated function key enables an “automatic” feature, it operates according to the states shown in the table. For instance,
enabling the Automatic Mars Light in Neutral will not cause the Mars Light to strobe since their automatic behavior would have them at a
steady-on setting in that directional state; however, it you then entered Forward, the Mars Light would begin to strobe. When an indicated
function key disables an “automatic” feature, that feature is off. For instance, disabling the “Automatic Mars Light” will immediately shut
off the Mars Light in any direction and they will not turn on again until the automatic feature is enabled.
Note: Use CV 55 to change the behavior of lights from what is shown in the above table and description.
Note: Lights and other features can be assigned to function keys and configured to different kinds of operation and initial conditions in CV 53 (Output
Feature Assignment) and CV 55 (QSI Feature Configuration). See the Quantum DCC Reference Manual, version 4.
Note: Cylinder Cocks can also be armed in Neutral with either the F7 key or the F6 Start Up key without having to wait for the 25 time out period.
Coupler and Coupler Crash Sounds (F3)
There are two ways to use the F3 key.
•
As your locomotive is about to couple up to a string of cars, press the F3 key to trigger the crashing sound of locomotive coupling. Use
the F3 key again as the locomotive moves out to trigger the same sound as the slack is taken up in the cars.
•
Use the F3 key in Neutral to produce uncoupling sounds as you disconnect cars over uncoupler magnets. Press the F3 key once to
produce the sound of the lift bar and coupling pin being raised. This first press also arms the uncoupling sound effect. Press the F3 key
again while moving or in Neutral to trigger the sound of the coupler knuckle opening and air-lines parting.
Sound-of-Power™
If CV 3, or CV 23 and CV 4, or CV 24 has been set to non-zero positive values, your steam locomotive will produce additional labored
Chuffing sounds under acceleration and lighter Chuffing sounds under deceleration. The level of labored sounds is proportional to the
values for these four CV’s, and how much the throttle is increased or decreased.
Note: When starting out after an extended period in Neutral (over 25 seconds), the Cylinder Cocks will vent 16 times or until speed exceeds 12 smph.
Whistle and Bell Buttons (F2, F1)
Some DCC controllers have separate whistle and bell buttons along with function keys assigned to whistle and bell operation. The bell is
usually assigned to F1 and the whistle is usually assigned to F2. The F2 key behaves differently than using the whistle button.
•
Pressing the F2 key and releasing it will cause the whistle command to come on and stay on, until you press F2 again.
•
Pressing the whistle button will send the whistle command only as long as you hold the button down.
Pressing the F1 key and releasing it will cause the Bell to come on and stay on, until you press F1 again. There is no difference in operation
between the bell button and its corresponding function key.
23 Not all features may be available in your locomotive model.
24 If your locomotive has the Mars Light, the Headlight will be off (instead of “Dim”) in all states except Forward where it will be Bright.
25 Most Quantum 1 and Q1a Reverse Lights cannot be dimmed; they only have bright and off settings.
In these cases, “Dim” is equivalent to “Off”.
26 Cylinder Cocks arming after Start Up and/or after 25 seconds in Neutral can be enabled/disabled in DCC using CV 51.2, which applies to both Analog and DCC operation.
