Special Operation and
Troubleshooting
For a full description, see the Troubleshooting section in the Quantum DCC Reference Manual (Version 3) at www.qsindustries.com.
With some Command Stations, using the horn button to activate the Horn, and, while this button is held down, activating the F6 Doppler
key, will cause the Horn to shut off instead of causing a Doppler shift effect.
We have experienced intermittent and independent horn signal interruption with some DCC command stations, causing unexpected
Doppler shifts. If this happens frequently, you may want to disable the Horn Triggered Doppler (CV 51.2).
Manual Volume Adjustment (Analog and DCC)
To adjust the volume by hand:
Locate the Manual Volume Control (potentiometer) on the roof of your Electric locomotive as shown in the
Electric Model
Specification sheet that was included with your model.
Use a small screwdriver to turn the potentiometer clockwise to increase volume or turn it counterclockwise to decrease the volume.
Note:
Volume can also be adjusted digitally using the programming methods described in the programming sections of this manual. However, if you turn
the volume down using the Manual Volume Control, you will not be able to increase the volume using programming above the level set by the
potentiometer.
Using the Quantum Reset Jumper to Return Your Locomotive to Factory Default Values (Analog and DCC)
In case your locomotive’s sound and control system misbehaves and turning the power off for 15 seconds does not return it to normal
operation, you can reset your locomotive to original factory values. The jumper
68
is located as shown in the
Electric Model Specification
sheet that was included with your model.
Turn off the power.
Remove the jumper by pulling it up.
Reapply power, after a few seconds your will hear the word “reset”.
Turn the power off, reinstall the jumper. The locomotive has now been returned 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
exceeds 21.5 volts peak, the motor drive circuit will automatically shut down and the locomotive will coast to a stop. The Quantum System
alerts you to the problem through a continuous series of Horn hoots. This built in safety feature protects the Quantum electronics and motor
from excessive voltage.
69
To restart your locomotive, reduce the track voltage until the hooting stops and the motors re-engage.
Program Track Operation
Your locomotive conforms to NMRA standards for program track operation. However, the Quantum System requires more current to
operate than standard DCC decoders and may not respond to the limited program track power from some command stations. If you are
unable to program in Service Mode on your program track, all CV’s in your locomotive can be programmed in Ops Mode. You can also
purchase from Tony’s Train Exchange®
70
, a simple, inexpensive power booster (PowerPak™ by DCC Specialties) that will allow you to
program on the program track with any DCC command station.
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 for 15 seconds does not return it to normal operation, try
the following suggestions to bring your locomotive back to normal sound operation.
Make sure the engine has not been Muted with the F8 key.
Check to see if your volume potentiometer or digital sound has been turned all the way down.
68
On some locomotives a slide switch was used instead of a jumper.
69
The high voltage circuit breaker will sometimes activate if the load (inertia or momentum) feature is used. Most power packs have substantial series resistance, which lowers the
track voltage when the locomotive is drawing power. However, with a load setting, the locomotive does not require much power when it first starts moving. If the throttle is turned
up all the way before the locomotive gains speed, the track voltage will be unusually high and can trigger the high voltage circuit breaker.
