Fan Cart Introduction
Introduction
The PASCO Fan Cart produces Low, Medium, High or Variable Thrust either continuously or for selectable time intervals of 1, 2, 4, or 6 seconds.
The direction of thrust can be adjusted from zero to 180 degrees to demonstrate the
vector nature of force.
The Fan Cart has a sophisticated rechargeable-battery powered electronic controller
that provides a constant voltage to the fan motor so that the Fan Cart approaches constant fan speed operation that is not dependent on the battery terminal voltage.
The Fan Cart nests on top of the PASCO Dynamics Cart or PAScar to utilize the
Dynamics Cart’s or PAScar’s plunger and bumpers.
The Fan Cart is compatible with all PASCO tracks (please see the PASCO catalog) or
can be used on a smooth surface without a track.
The Fan Cart comes with a Sail for the “Fan Cart with Sail” demonstration.
The Fan Cart has a light-emitting diode (LED) that indicates when the battery is being
charged. The LED flashes when the battery is low.
Battery
The Fan Cart’s high energy density lithium-polymer battery can run the fan continuously at medium thrust for about 1.5 hours before the ‘low-battery’ LED begins to
flash. Since the battery recharges quickly (typically in one hour), even short periords
(10 - 20 minutes) with the charger plugged in will recharge the battery sufficiently to
continue.
• Partial charging and recharging will not adversely affect the battery life.
• The replaceable battery pack is designed to last at least five years in normal
application.
• Unlike nickel-cadmium batteries, for maximum battery life, the lithium-polymer
battery pack should not be run down completely before recharging.
• The battery pack can be left in a partially charged state for long periods without
damage.
• Maximum battery life can be attained by charging the battery after each use.
• The charger may be left connected indefinitely because it shuts off automatically
after the battery reaches full charge.

Operation
The control section of the Fan Cart has eleven light-emitting diodes (LEDs), a
VARIABLE THRUST knob, and three selector switches: THRUST, PULSE TIME,
and FAN ON, STANDBY. The CHARGING LED flashes when the battery needs to
be recharged and stays lit while the Fan Cart is charging.

selector switch
FAN ON, STANDBY, and OFF
To turn on the Fan Cart, press the FAN ON, STANDBY selector switch. The LEDs
will light momentarily, and then the green LED next to STANDBY will remain lit.
To turn on the fan, press the FAN ON, STANDBY selector switch again. The fan
will turn on and the yellow LED next to FAN ON will remain lit. The default setting
is continuous blowing at LOW THRUST.
To turn off the fan, press the FAN ON, STANDBY selector switch again. The fan
will turn off and the green LED next to STANDBY will remain lit.
To turn off the Fan Cart, press-and-hold the FAN ON, STANDBY selector switch
for one or two seconds. The green LED next to STANDBY will stop shining.
THRUST Settings
To change the THRUST setting from the default value (LOW), press the THRUST
selector switch once to select MEDIUM. Press the selector switch again to select
HIGH, and press the selector switch again to select VARIABLE. Press the selector
switch once again to return the THRUST setting to the default value.
When the THRUST setting is set to VARIABLE, turn the VARIABLE THRUST
knob clockwise to increase the thrust or counterclockwise to decrease the thrust.
CAUTION!
Keep fingers and other
objects away from the moving
fan blade.
NOTE: The Fan Cart turns
itself off if is not used for ten
minutes.
You can change the THRUST setting while the fan is in STANDBY, or while the fan
is on.
PULSE TIME Settings
You can change PULSE TIME settings only while the fan is in STANDBY.
Press the PULSE TIME selector switch once to select 1 s (one second). Press the
switch again to select 2 s (two seconds). Press the switch again to select 4 s (four seconds), and press the switch again to select 6 s (six seconds).
