High Voltage Circuit Breaker; Program Track Operation; Using The Reset Jumper Block To Return Your Locomotive To Factory Default Values - Lionel HO Veranda Owner's Manual

Special Operation and Troubleshooting

High voltage circuit breaker

Y our 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, while the Quantum system
alerts you to the problem through a continuous series of horn blasts. This built-in safety feature
protects the Quantum system and motor from excessive voltage. To restart your locomotive,
reduce the track voltage until the horn blasts stop and the motor re-engages.

Program track operation

Y our locomotive conforms to NMRA standards for program track operation. However, the
Quantum Sound system requires more power to operate than many standard decoders
provide, limiting your locomotive's response to the program track power from many command
stations. If your program track will not respond properly, all CV's in your Challenger can be
programmed in Ops mode.
Using the reset jumper block to return your locomotive to factory
default values
I f you experience abnormal sound and control system operations, simply turn off the power for
15 seconds. If operation does not return to normal, follow these steps to reset your locomotive to
original factory settings. The switch is located under the roof-top hatch on the locomotive.
1. Turn off track power.
2. Remove the roof-top hatch and
pull up the reset jumper using a
pair of needle-nose pliers.
3. Place the tender on the track
and restore power. After a few
seconds, the horn will respond
with a series of three blasts.
4. Turn off track power and
replace the jumper and roof-top
hatch
