INSTALLATION IN EXPLOSIVE AND
FIRE DANGER ZONES
Micropump oers products designed and tested for installation in explosive or re
danger zones. Contact your local Micropump distributor or contact Micropump directly
to deter mine if your EagleDrive product combination can be certied for this use.
In addition to the warnings provided throughout this manual, the following must be
consid ered in any explosion or re danger zone installation:
DESCRIPTION
The EagleDrive is a brushless DC motor with integrated controller specially designed
to be electromagnetically coupled to a variety of Micropump pump heads. When
properly assembled to the pump head with sealing o-ring, this comprises a sealed
unit where the driven magnet is within a magnet cup that separates the pumped uid
from the atmosphere.
There are two EagleDrive models, the DEMSE and DEELE. The enclosed versions
are within a thermoplastic housing. The motor is capable of rotating in both
directions and has speed control input options. A tachometer signal, with a 0-5 V
square-wave output provides speed feedback. The tachometer output has 2 pulses
per revolution. The output frequency is multiplied by 30 to obtain RPM. The main
input power is 12-36 VDC from a class 2 (SELV) source.
Both EagleDrive models can be controlled using one of these options:
1. Externally applied 0-5 VDC supply
2. Externally applied PWM
(Pulse Width Modulation) signal
3. Externally applied 4-20 mA signal
(conditioned with external resistor)
4. Manually-adjusted speed
control (through use of external
potentiometer)
FUNCTION
The driven magnet is connected to the pumping parts and is sealed in the magnet
cup. This magnet forms the rotor of the brushless DC motor and is driven by the
rotating magnetic eld in the stator. Rotation of the pumping elements produces ow.
The control signal (supplied internally or externally) controls pump speed. Internal
feedback monitors the rotational speed of the pump and regulates the speed in
relation to the control voltage. The controller increases current to regulate speed
against increasing back pressure (within the operating limits of the pump and motor).
Ensure the pump head,
motor, and any mounting
adapter are suitable for
area classication.
Ensure that pumping liquid
temperature, and motor
housing temperature are
maintained within acceptable
range as specied by
Micropump Certication of
ATEX Conformity.

DOC No: PN 86880 REV A

If the pump head housing assembly and EagleDrive motor are supplied separately
they will need to be assembled prior to the installation.
Pump head should have a gasket attached to the mounting plate. If not, attach p/n
L28880-Gasket (1) to the drive side of the mounting plate. Carefully place the
gasket as concentric to the mounting plate as possible. After gasket (1) is
adhered to mounting plate (2), apply a light coating of silicone grease to the
gasket. Align the pump assembly ange (2) so that it matches with the cam locks
in EagleDrive housing (3), then rotate clockwise to lock and align with mounting
screw holes. Secure using the two screws (4) supplied with the EagleDrive.
Torque screws to 0.8 N-m (7 in-lbs).
SPACE
REQUIREMENTS
Refer to the Technical Specication
for overall dimensions and weights of
the EagleDrive and some of the most
common pump/motor combinations.
UNPACKING AND STORAGE
Inspect the magnet cup before assembly with the motor. Replace or
repair if there are signs of damage.
Loose bolts may result in pump/motor misalignment. Tighten bolts
appropriately. Pump/motor misalignment may result in weakening the
sealing of the enclosure. Drive housing seal described below is
required for IP55 rating.
Before installing the product ensure all transit packaging has been removed.
Remove the blanks from any inlet and outlet ports. If the pump is to be stored
prior to installation, re-pack the pump in its original packing, ret the blanks to
the ports and store in a dry, covered environment.
Protect the pump head from damage during unpacking and installation. Impacts
to the magnet cup can cause internal damage or result in rub between the
magnet cup and driven magnet upon assembly with the motor.

LOCATION
Pump head cannot support the weight of the motor. Ensure
the motor is adequately supported by the foundation and/or
mounting bracket.
The foundation must be capable of supporting the combined weight
of the pump and motor and provide a rigid support.
The product should be located with the inlet below or even with the liquid level of
the uid supply. The product can be mounted in any position. Ensure that there is
adequate space for operation, inspection and maintenance.
BULKHEAD MOUNTING
(DEELE MODEL)
If mounting the pump/EagleDrive assembly through a bulkhead, insert the
bulkhead o-ring (ITEM 1) into the groove in the face of the housing (ITEM 3).
Position the adaptor ange (ITEM 2) through the bulkhead hole so that it does
not interfere with the sealing of the bulkhead hole. Secure the pump/EagleDrive
assembly using four screws, nuts, and washers as needed. Tighten screws evenly
and in an alternating pattern.
ITEM 1: o-ring 2-040 described below is necessary to ensure
bulkhead is sealed.

REQUIRED EAGLEDRIVE
ELECTRICAL CONNECTIONS
Electrical installation must be carried out by qualied personnel
who are conversant with local electricity installation regulations.
Before starting any electrical installation work ensure that the main
electrical supply is adequately isolated.
Ensure that the pump motor is earthed. The pump may be electrically
isolated from the motor depending on the mounting conguration.
Some installations may need an earthing connection on the pump head.
Pumping ammable uids without a proper earthing connection may
cause spontaneous ignition.
Ensure that all electrical connections use a common earth ground to
avoid hazardous ground loops.
MAIN Power In
24 +/- 12Vdc (nominal), voltage ripple must be maintained below 5% peak-to-peak,
from SELV Class2 or Limited Power Source, Micropump always recommends
external overcurrent protection (MODEL MS ~2A, MODEL EL ~3A), internal
hardware-current-limit decreases motor speed to hold at current limit until rotation
stops (stall), in locked-rotor condition maximum stall current is ~1.2A.
If locked rotor operation occurs at full load current in greater
than 70°C ambient temperature conditions can result in winding
temperatures greater than UL 1004 limits. To reduce risk of
exceeding winding temperature limits Micropump recommends
always monitoring the tachometer signal and commanding stop
if the pump shows a locked rotor condition lasting more than
one minute.
Ensure that the voltage of the supply is correct for the motor being
connected, and that the source is SELV Class 2 or a Limited Power
Source. Ensure that the power supply voltage ripple is maintained
below 5% peak to peak.
Ensure that all associated equipment has a form of overcurrent
protection. If a fuse is used see table below for recommendations.

EAGLEDRIVE ELECTRICAL
CONNECTIONS (CONTINUED)
Common Ground
Main Power IN voltage, control signal inputs, and all outputs use a common
ground. It is possible that ground potential dierences between the power
supply, control voltage source and the other devices (if used) will be forced to the
same ground reference when connected to the EagleDrive. Ensure only one earth
ground is used to avoid ground loops.
Analog DC Control Signal In
-0.3 to 5.1Vdc control input, motor set to zero rpm -0.3 to +0.2V, motor set to 100%
above +5.0V as read with ADC channel on microprocessor Input impedance ~6 kohm,
input is not clamped and must remain below 5.1V max at all times Internal 100k pull
down on input provided positive stop should lead be disconnected.
Input Voltage vs RPM is proportional within a given mains voltage (i.e. % of 5.0V = %
of maximum motor speed as dened by main power in controlled by 8-bit microprocessor
signal, operating open-loop-speed with motor max output current limited.
PWM (Pulse Width Modulation) Speed Control
% Positive duty cycle within 3% to 97% at 20-100Hz frequency results in motor
speed proportional to the input (i.e. % of Positive Duty Cycle = % of maximum
motor speed at dened main power in), motor set to zero rpm 0 to 3% and 97 to
100% controlled by 8-bit microprocessor signal, operating open-loop-speed
with motor max output current limited.
Input impedance ~6 kohm, input is not clamped and must remain within -0.3 to
1.5v (Lo) and +3.5 to 5.1V (Hi) or the motor will be irreparably damaged.
To enable PWM IN the EagleDrive must read a “high” level signal (greater than
97% +Duty Cycle PWM signal) during each application of main power in (when
rmware POST is occurring) to choose PWM IN mode. The EagleDrive will
otherwise default to Analog DC Control Signal IN mode.
Example of Control Signals Necessary to Select PWM IN Mode:

4-20mA CONTROL CONFIGURATION
To maintain protection of internal drive controller, your external
resistor should be tted with appropriate protection.
4-20mA Control
Install a 250 Ohm resistor across the white Speed Input and black Common
lead wires. Applying current across this resistor will result in a commanded
proportional speed from the Eagle Drive.

OTHER EAGLEDRIVE
ELECTRICAL CONNECTIONS
Tachometer Output
The tachometer output can be monitored using a frequency counter. The
tachometer output is 0-5V square wave pulse that occurs twice per pump drive
revolution. To convert the tachometer output to rpm, multiply the output
frequency (Hz) by 30.
Inadvertent connection of the tachometer output (green) wire to
ground or the supply voltage can cause damage to the drive. If the
tachometer is not used, trim and insulate the green lead.
Forward/Reverse Operation
The direction of uid ow can be changed by connecting the orange wire to
ground. For FORWARD ow, make NO CONNECTION to the orange wire. For
REVERSE ow, connect the orange wire to GROUND.
DO NOT reverse the direction of rotation of the drive until the drive
has come to a complete stop. Reversing the direction while the drive
is still turning may damage the motor.
Inadvertent grounding of the forward/reverse (orange) wire will cause
the drive to operate in reverse. If reverse operation is not required, trim
and insulate the orange lead.
Motor/Pump performance will be dierent between FWD and REV
operating modes.
Motor Current Output
The Motor Current Output is an analog signal (from 0 to 5vdc) that is proportional
to the actual motor amps. This signal is not heavily ltered so the actual motor
phase waveform will be visible in the signal. To use this most eectively rst
measure the signal with no speed input command to determine the oset value.
The actual signal will then be according to:
Motor Current Output = (0.95 x Actual Amps) + Oset for DEMSE products
Motor Current Output = (0.63 x Amps) + Oset for DEELE products.

OPERATION
Starting or running the pump with the discharge valve closed may
result in overpressure in the discharge pipe.
Extended periods of dry running may result in permanent damage to
the pump and may cause surface temperature to exceed the operating
temperature of the pump. Ensure that the pump head temperature does not
exceed the ash point temperature of the uid or area. Shut down pump for
a no uid condition. Shut down the pump for a no ow condition.
Ensure the pump head temperature does not exceed the ash point
temperature of the uid or area.
Start-up Procedure
Before starting the pump ensure that any valves in the inlet or discharge lines are
open and that any inlet lters are clean and free from obstruction.
1. Set the external control signal input to minimum value (0 VDC) or >97% PWM IN
2. Set the Main Power IN (12 VDC to 36 VDC) to ON. With the control input set to
0V or < 3% PWM IN the pump will show a nominal 25mA to 100mA current draw
and will not turn.
3. Adjust the control signal input to the required level. Current demand will rise
and fall as the pump load and speed varies.
Once started the pump should prime if it has not already been lled with uid. If
the pump fails to prime, stop the pump and ll the pump head with liquid.
Post Start-up Checks
Once the pump has started, carry out the following checks:
1. Check that the pump and motor operate smoothly and are free from vibration.
2. Check the inlet and discharge ttings are free from leaks.
Flow rate should always be adjusted by controlling motor speed where
possible. Ensure that overpressure does not occur in the discharge
pipe. NEVER throttle ow by an inlet valve.
Shut-down Procedure
Switch o the EagleDrive by:
1. Slowly decreasing the external control signal input to the minimum value.
2. Check that the unit runs down in a steady manner.
3. Switch o power supply.
Once stopped, close the inlet and discharge valves. Drain the pump if it is to be
shut-down for long periods or installed in areas where the liquid may freeze. Refer
to the Maintenance section for instruction on draining.

DOC No: PN 86880 REV A
19
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.
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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 ushed
with a suitable ushing agent or precautions are taken against the
eect of any remaining liquid during servicing. When the pump has
been handling ammable, toxic or hazardous uid, the pump internals
must be properly decontaminated by suitably quali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 uid circuit to keep 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.

DOC No: PN 86880 REV A
20
MOTOR WILL NOT OPERATE
Cause Remedy
No power to motor. Ensure proper voltage has been applied to motor power leads.
Check leads to ensure no short circuits are present.
Control Input lead is shorted. Clear and isolate Control Input lead from Tachometer Out lead.
Clear and isolate Control Input lead from Common lead.
No Control Input applied. Ensure proper control input is applied to control Input lead: for
0-5V, ensure line is not shorted. If manual control EagleDrive,
adjust potentiometer to increase control voltage. Ensure control
power supply common is connected to the common lead.
Thermal Limit is active. Turn o motor and wait for temperature to cool. NOTE: If power
voltage and control signals are present, motor will automatically
restart when temperature is reached. Reduce motor load
conditions and/or improve cooling of motor housing if persistent
limit occurs.
Motor has been damaged. Contact your Micropump Distributor or contact Micropump
directly for replacement product.
CYCLIC NOISE OR VIBRATIONS
