Manual Control
Install a resistor (sized according to your voltage supply input) across the red Power
In and black Common lead wires. The potentiometer wiper is connected to the yellow
Speed Input lead wire. To increase speed, rotate the potentiometer to increase voltage to
the control line. To decrease speed, rotate the potentiometer to decrease voltage to the
control line.

Maintenance
Excessive wear to the pump can result in driven magnet rub on the
magnet cup. This can generate high surface temperatures or degrade the
capability of the pressure boundary. Remove the pump from service and
replace or repair if pump performance degrades signi
fi
cantly or the pump
becomes noisy.
Ensure that heavy deposits of dust are not allowed to accumulate. Clean
the pump periodically.
The pump cannot be drained completely, a certain amount of liquid will
remain in the magnet cup area. Ensure that the pump is either
fl
ushed
with a suitable
fl
ushing agent or precautions are taken against the effect
of any remaining liquid during servicing. When the pump has been
handling
fl
ammable, toxic or hazardous
fl
uid, the pump internals must
be properly decontaminated by suitably quali
fi
ed personnel. The Material
Safety Data Sheet for the pumped liquid must be referred to for correct
procedures and precautions to be followed when handling the liquid.
Micropump EagleDrive motors are designed to be maintenance free and require no
adjustments. To ensure the motor or pump/motor assembly retains optimum performance
maintain the
fl
uid circuit to keep
fi
lters clean and prevent abrasive solids from passing
through the pump.
A program that includes periodic monitoring of your Micropump product is
recommended to provide timely detection and assessment of any problem.
NOTE
Magnet Decoupling
The EagleDrive pump/motor combinations do not decouple. If pump load becomes
excessive, current limiting in the controller prevents motor overload. Additional protection
is provided by a thermal sensor which shuts down the drive if the internal temperature
exceeds a preset value.
