Transformer operations
Your locomotive’s Odyssey™ System speed control
You can lock your locomotive into speed
control mode (ideal for low speed opera-
tion) so it will automatically compensate for
grades and heavy loads, always maintaining
a specific speed setting. To turn on the
speed control, get your locomotive mov-
ing at the desired speed, in forward or
reverse. Let it run at the desired speed for at
least 5 seconds. Press and hold the
horn/whistle button on your transformer for
2-3 seconds as you increase the throttle by at
least 3 volts. Your locomotive will accelerate
briefly and will then return to your set speed.
You can then release the horn/whistle but-
ton. As long as the throttle position is main-
tained at a higher setting than the initial
level, your locomotive will maintain a con-
stant speed. If the throttle is turned below the
original level, your locomotive will slow
down as the voltage decreases below the “set”
level. To check if the speed control setting
has been “accepted,” turn up the throttle.
You will see the lights brighten, but the speed
will remain constant. For best results, adjust
the track voltage about 3-4 volts above the
“set” point. This will provide enough spare
voltage to compensate for uphill grades, etc.,
but will prevent excessive voltage to the
lamps and smoke unit. (In conventional
mode, these features operate at track voltage,
and excessive voltage may lead to premature
bulb burn-out.)
• If you wish to change the speed control
setting, you must deactivate the speed
control, then reactivate at the new
setting.
To turn speed control off, get your
locomotive into neutral for at least 5 seconds,
then increase the track voltage to full power
with the throttle on your transformer. This
will give you more “room” to lower the volt-
age. Press the horn/whistle button on your
transformer for 2-3seconds while lowering the
throttle voltage to 1/4 of full power, or at least
three volts. The speed control deactivates
when it sees a 3 volt change with the
horn/whistle button pressed, regardless of
initial voltage level. Do not turn the throttle
off, or speed control may not deactivate.
Note! Speed control settings are retained in memory even if power is turned off.
They will remain present until deactivated.
