QSI Quantum 1 System Operation Manual page 12

Pressing the F7 key when the locomotive is moving at any speed will manually activate Squealing Brake sounds, and repeated
pressings while the Squealing Brake sounds are occurring will continue the sounds uninterrupted.
Note: If you slow the engine too quickly, the brake sounds will terminate abruptly when the locomotive stops and enters Neutral.
Note: If you lower your throttle to speed step 0 on a moving locomotive, the F7 key will apply Air Brakes to slow the locomotive. See next section.
Air Brakes (F7)
If you have selected any non-zero deceleration inertia or momentum value in CV 4 and/or CV 24, the F7 key can be used to apply Air
Brakes to stop the locomotive more quickly than it would normally stop from the inertia settings
Turn the throttle down to speed step 0 on a moving locomotive; this enables the F7 key to act as a brake.
Press the F7 key. Hear a brief brake squeal sound and air being released from the brake lines continually. The longer the air is
released the greater the braking action.
Press the F7 key again to stop the air release. The train will continue to slow at the last braking value.
If you want to apply more braking, press the F7 key again to release more air. When you reach the desired amount of braking, press
F7 again to stop the air release.
Note: If you continue to release air (for over 24 seconds total), all the pressure will be released and brakes will be on full; you will hear no further air
release sounds.
Turn up the throttle to any value above 0 to release the brakes; this action resets the locomotive's deceleration to a value determined
by the sum of CV 4 and CV 24.
If the locomotive is in Neutral when the F7 key is pressed, a Long Air Let-off sound simulates setting the brakes. However, no braking
effect is activated 48
Note: If the throttle is set to any speed step except 0, Air Brakes are not enabled; instead the F7 key will now manually activate Squealing Brake/Flange
sounds but will not affect the locomotive's deceleration.
Automatic Features with "Take Control" Operation
The Quantum System allows the operator to take control of certain automatic features by using their associated function key or keys. Once
you "Take Control", the features will no longer have automatic operation and you will control their operation and their state with function
key commands. Automatic and Take Control operations are described in the table below.
Electric Locomotive "Take Control" Operation
Forward
Vents & Cooling Non-operating
Fans
Number Board On
Lights
Cab Lights Off after 15 seconds
Example: Take Control of Automatic Cooling Fans
Take Control of Automatic Cooling Fans with the F4 key to stop Automatic Control and select whether the Cooling Fans are on or off.
Regardless of the state of the automatic Cooling Fans (on or off), if you press the F4 key, the Cooling Fans will be set to on if the F4 key is
"1" and off if the F4 key is "0" and Automatic Control will be disabled. Thereafter, the fans will respond only to the state of the F4 function.
Automatic Control will be restored if the power is shut down and reapplied or if the F6 Start Up key is double pressed in Neutral (see the
description of Start Up on the following page).
Three Stages of Electric Locomotive Shut Down: 1. Disconnect, 2. Standby, 3. Total Shut Down (F9)
Locomotive Shut Down has three distinct stages that you can control. Each stage is entered by double pressing the F9 key
Stage One: Disconnect
Double press the F9 key in Neutral to enter Disconnect. You will hear a Long Air Let-off.
47 C4 and C24 determine the deceleration rate. Applying the brakes increases the deceleration rate temporarily.
48 If the brakes are set in Neutral, turning up the throttle automatically releases the brakes.
49 Double pressing ensures that Shut Down stages are not entered or exited accidentally. Double pressing is defined as two F9 commands sent within two seconds. Note that the
F9 key may have to be pressed three times, due to the DCC command station and locomotive having different initial states for F9.
