Steam Q1a Operation Manual Rev 4.1.2

•
Locate the reed switch area on the tender as shown in the
Steam Model Specifications sheet that came with the locomotive.
•
Turn off the power.
•
Place the Magnetic Wand over the reed switch area and apply power and leave the wand there until you hear the word “Reset”. Your
locomotive is now reset to original factory defaults including all DCC and Analog values.
High Voltage Circuit Breaker (Analog and DCC)
Your Quantum equipped locomotive is designed to operate on normal HO track voltage supplied by most HO power packs. If track voltage
gets too high
50
, the motor drive circuit will automatically shut down, and the locomotive will coast to a stop. The Quantum System will alert
you to the problem through a continuous series of Whistle hoots. This built in safety feature protects Quantum electronics and the electric
motor from excessive voltage
51
.
•
To restart your locomotive, reduce the track voltage until the hooting stops and the motors re-engage.
Note: Later Quantum equipped locomotives use a different motor control design, which will operate at a higher voltage.
Reasons why your Locomotive is Silent or will not Start (Analog and DCC)
In case your locomotive remains silent after power up and turning the power off and back on does not return it to normal operation, try the
following suggestions to bring your locomotive back to normal sound operation.
•
Make sure the locomotive has not been Muted with the DCC F8 key or Quantum Engineer Mute Key.
•
Check to see if your Manual Volume Control or Programmed Digital Volume has been turned all the way down.
•
You may have shut down your locomotive in DCC using the F9 key, or in Analog using the Quantum Engineer Shut Down key. Use the
F6 key in DCC or the Quantum Engineer Start Up key in Analog or use the Magnetic Wand in Analog, which both selects and starts the
locomotive.
Note: The Magnetic Wand will not start your locomotive in DCC if it is in a Shut Down state. To start in DCC, you must first select the locomotive with
its ID number and then use the F6 key. It will take a couple of seconds after you double press the F6 key before you will hear the pump sounds
start.
Note: It does not make any difference whether you start your locomotive in DCC or DC. Once started, you can return to either DC or DCC operation.
•
If the above methods do not start your locomotive, use the magnetic wand to reset your locomotive to factory default values as
described above.
Upgrading to New Sounds and Features
The Q1a Upgrade Chip contains software that will allow it to reprogram itself using a PC and the QSI Programmer module, which in turn is
wired to a program track. Using this method, the Q1a chip can be upgraded to new software, enhanced with new features, and new or
different sounds. New software and sounds sets will be available through the QSI website at http://www.qsindustries.com. Refer to the
operating instructions and documentation supplied with the Quantum Programmer.
50 The High Voltage Circuit Breaker is set to trip at 21.5 peak volts.
51 The high-voltage circuit breaker will sometimes activate if the Load (inertia or momentum) feature is used and the throttle is turned up too quickly to full power.
