•
Use a Slow or Quick operation of the direction switch to enter this option. You will hear “V-Start equals X” where “X” is the track
voltage value currently set for leaving Neutral.
•
Use a Slow or Quick operation of the direction switch to activate this option. Hear the message “Set throttle to V-Start.” After three
seconds, the voltage will be announced. If you move the throttle, the new track voltage value is announced a few seconds later.
•
Once throttle is set, use a Slow or Quick operation of the direction switch to start the V-Start voltage setting procedure. The locomotive
will move at a slow speed and the Bell will ring continually for about 25 seconds, indicating the correct value is being calculated. If you
chose a very low voltage setting, be patient. If the locomotive does not move during this procedure, return to the beginning of this
option or start over
17
and then chose a slightly higher throttle setting.
•
At the end of the process, the locomotive will stop moving and the Whistle will hoot, signifying the end of the operation, and you will
hear the message “V-Start = X” where “X” is the new setting.
•
To leave Programming, turn the throttle off, and then power up for normal locomotive operation.
•
Or continue to V-Max by moving the direction switch and waiting for the next Programming Option to be announced.
Example 3: Setting V-Max (Program Option # 9)
V-Max is set in the same manner as V-Start except after entering this Program Option, you will hear “Set throttle to V-Max” which is the
throttle position where you want the full track voltage to be applied to the motor (usually about 80% of full throttle)
18
. Then do a Quick or
Slow operation to start the V-Max setting procedure. Like V-Start, the bell will ring continually until the voltage is set followed by a Whistle
hoot to indicate the procedure is finished. Setting V-Max is much quicker than V-Start.
Note: During the V-Max setting, the locomotive will not move as it does under V-Start.

17 See section above: Moving on to Other Program Options or Leaving Programming.
18 V-Max should not be set too low when using RTC. For most MRC™ power packs, the best choice for V-Max is about 1.5 volts below the highest throttle setting as determined by
the Quantum built-in Voltmeter.
