Stage Two: Standby
•
Double press the F9 key while in Disconnect to enter Standby. You will hear a Long Air Let-off followed by a special “Idle” state where
Directional Lighting and optional Ditch Lights or Mars Light will shut down.
Note: The motor will remain disconnected, while the Blowers shut down; Automatic Number Board Lights and Cab Lights will continue to operate. In
Standby, the locomotive will not respond to throttle or function keys
30
. The three exceptions are the F6 Start Up Key, the F8 Mute Key
(described below) and the F10 Status Key (described below).
•
To leave Standby, either double press the F6 Start Up Key, as described in the Start Up section, or double press the F9 key again to
reach the final stage of Shut Down: Total Shut Down.
Note: Standby is ideal for leaving your locomotive in an idle state on a siding. Besides hearing occasional Air Pump sounds, the locomotive will not
respond to accidentally changing the throttle setting or pressing the function keys.
Stage Three: Total Shut Down
Total Shut Down allows the operator to take the locomotive “off line” (turn off sounds, lights, ignore throttle settings and function
commands) independent of the operating session: the locomotive will still be “off line” when power is reapplied for the next operating
session, regardless of whether the next session is Analog (conventional DC) or DCC.
•
Double press the F9 in Standby to enter Total Shut Down. You will hear a Long Air Let-off. The Air Pumps will turn off, followed later by
the sounds of Pop-Off operating for about ten seconds followed by hiss that gradually trails off to silence. The Number Boards (if so
equipped) will turn off and finally, the Cab Lights (if so equipped) will turn off.
Note: In Total Shut Down, the locomotive will not respond to throttle or function keys. The two exceptions are the F6 Start Up Key (described below)
and the F10 Status Key (described below).
•
To leave Total Shut Down, double press the F6 key.
Note: If power is turned off at any stage of Shut Down (Disconnect, Standby or Total Shut Down) or during a Shut Down procedure, the locomotive will
remember the last Shut Down stage it was at during power down, and the locomotive will power up in the same stage. If Start Up is initiated during
any of the above Shut Down procedures, Shut Down is aborted, and locomotive will return to normal operation.
Dynamic Brakes (F5)
Prototype steam locomotives do not have dynamic brakes. However, the Dynamic Brake function has been included to make the Quantum
steam locomotive consistent with other Quantum equipped locomotives in consists.
•
Pressing the F5 key in Forward or Reverse will reduce steam exhaust Sound-of-Power to the lowest setting allowing the steam labored
sounds to be consistent
31
with other locomotives that do have Dynamic Brake sounds in multiple unit consists.
•
Pressing the F5 key in Neutral will have no Dynamic Brake effect.
Dynamic Brakes automatically turn off when entering or leaving Neutral, when locomotive speed drops below 7 smph (11 skph)
32
, or when
the throttle is turned up. Dynamic Brakes cannot be turned on in Forward or Reverse unless the locomotive speed is over 8 smph (13 skph).
Note: In contrast to Air Brakes (F7), Dynamic Brakes do not increase the deceleration rate specified by CV 4 and CV 24.
Start Up (F6)
If your Quantum equipped steam locomotive is in any stage of Shut Down, you can return it to normal operation by double pressing
33
the F6
key. Start Up will be different for each stage of Shut Down, but all will start up with a Long Air Let-off and will enter normal operation.
Start Up from Disconnect: If you double press the F6 key in Disconnect, the steam locomotive will produce a Long Air Let-off, and the
locomotive will enter normal operation.
Start Up from Standby: If you double press the F6 key in Standby, the steam locomotive will produce a Long Air Let-off, Directional Lighting
will turn on, and the locomotive will enter normal operation.
Start Up from Total Shut Down: If you double press the F6 key in Total Shut Down, the steam locomotive will produce a Long Air Let-off, the
Dynamo revs up and the Directional Lighting turns on, Cab Lights come on (if so equipped), Number Boards come on (if so equipped),
followed by Air Pumps starting up, the steam Blower turning on and the locomotive entering normal operation.
Note: During the Start Up procedure, none of the DCC function keys are active. However, if the throttle is turned up from zero during any of the above Start
Up procedures, the Start Up procedure will abort and the locomotive will enter normal operation.
30 Pressing a function key will only produce a Short Air Let-off.
31 It would be inconsistent for a steam locomotive to be working at full Sound-of-Power while Dynamic Brakes are being applied to other locomotives within the same consist.
32 Dynamic Brakes on prototype locomotives are less effective and are seldom used at low speeds.
33 Double pressing is defined as two F6 commands sent within two seconds. Note that the F6 key may have to be pressed three times, due to the DCC command station and
locomotive having different initial states for F6. Double pressing ensures that Start Up is not entered accidentally.
