DOC No: 7936 REV D
Installation in Explosive and Fire Danger Zones
The I-Drive motor is not designed or intended for use in explosive or re danger zones.
Contact your local Micropump distributor or contact Micropump directly to determine a
pump/motor assembly that can be certied for this use.
The I-Drive cannot be certied for use in potentially explosive
atmospheres.
Description
The I-Drive 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 compromises a sealed unit where
the driven magnet is within a magnet cup that separates the pumped uid from the
atmosphere.
The brushless DC motor is enclosed by an anodized aluminum housing and a
polypropylene cover. The motor is capable of rotating in both directions and has 0-5 V,
4-20 mA or manual speed control input. 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 24 VDC
from a class 2 (SELV) source.
There are two I-Drive models, the IMS and IEG. Both models are available in 24 VDC
versions only, with speed control and power supply as separate functions. Each model
has 0-5 V square wave tachometer feedback and FWD/REV capability.
Both I-Drive models can be controlled using one of three options:
1. Externally applied 0-5 VDC supply
2. Externally applied 4-20 mA signal
3. Adjustable manual speed control located at the rear of the unit
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 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 maintains the speed in relation
to the control voltage. The closed loop controller increases current to maintain speed
against increasing back pressure (within the operating limits of the pump and motor).

DOC No: 7936 REV D
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.
Inspect the magnet cup, hub, or adaptor (if present) before assembly
with the motor. Replace or repair if there are signs of damage.
If the pump head housing assembly and I-Drive motor are supplied separately they will
need to be assembled prior to the installation.
Insert the sealing o-ring (1) into the groove in the face of the I-Drive (3). Align the adaptor
ange (2) so that it ts into the matching recessed on the I-Drive housing. Secure
using the three screws (4) supplied with the I-Drive. Tighten screws evenly and in an
alternating pattern. Torque screws to 0.8 N-m (7 in-lbs).

Loose bolts may result in pump/motor misalignment. Tighten bolts
appropriately. Pump/motor misalignment may result in weakening the
sealing of the enclosure. O-Ring 2-070 described below is required for
IP55 rating.
Assembly
Unpacking and Storage
Proper assembly is required to prevent magnet rub due to misalignment.
Space Requirements
Refer to the Technical Specication for overall dimensions and weights of the I-Drive and
some of the most common pump/motor combinations.

DOC No: 7936 REV D
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.
Location
Pump head or adaptor 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.
Bulkhead Mounting (IEG Model Only)
If mounting the pump/I-Drive assembly through a bulkhead, insert the bulkhead o-ring (1)
into the groove in the face of the I-Drive (3). Position the adaptor ange (2) through the
bulkhead hole so that it does not interfere with the sealing of the bulkhead hole. Secure
the pump/I-Drive assembly using four screws, nuts, and washers as needed. Tighten
screws evenly and in an alternating pattern.
EMC Compliance
To maintain EMC compliance, the shield (bare wire) is connected internally to the motor
housing through a 220nF capacitor.
NOTE
Compliance with EMC Directive 89/336/EC and subsequent amending
directives is only applicable when the drive is used with the power lead that
has been supplied. Use of another power lead may result in non-compliance.
O-Ring 2-033 described below is necessary to ensure bulkhead is
sealed.

DOC No: 7936 REV D
Pumping ammable uids without a proper earthing connection may
cause spontaneous ignition.
I-Drive Electrical Connection
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.
Before starting any electrical installation work ensure that the main
electrical supply is adequately isolated.
Electrical installation must be carried out by qualied personnel who are
conversant with local electricity installation regulations.
Ensure that the voltage and frequency of the supply are correct for the
motor being connected, and that the source is Class 2 or a Limited
Power Source.
CAUTION
Ensure that all electrical connections use a common earth ground to
avoid hazardous ground loops.
Ensure that only power supplies having SELV specication are
connected to the I-Drive.
CAUTION
Ensure that all associated equipment has a form of overcurrent
protection. If a fuse is used see table below for recommendations.
CAUTION
The I-Drive does not have reverse-polarity protection. If the common
(black) lead is connected to the positive terminal of the power supply the
motor will be irreparably damaged.
CAUTION
Power In
The main input power is 14 to 30 VDC from a Class 2 (SELV) source applied across the
power in and common ground leads. This voltage must be maintained within the specied
limits as the motor is loaded to its maximum current of 1.8A (Model - IMS) or 2.9A
(Model - IEG.)
Ensure that the power supply voltage ripple is maintained below 5% peak
to peak.

I-Drive Electrical Connection (Continued)
Control Signal In
For motors having 0 to 5 VDC or 4 to 20 mA speed control, when the lead is connected
to a supply within the range the motor speed is proportional to the input. If the lead is
connected to a greater input, the motor will run at its maximum speed. If the lead is
connected to a lesser (or reverse polarity) input, the motor will stop.
Common Ground
The input voltage, the 0 to 5 VDC control input, and the tachometer output all use a
common ground. It is possible that ground potential differences between the power
supply, control voltage source and the frequency counter (if used) will be forced to the
same ground reference when connected to the I-Drive. While not typical, in some cases
large current ows can result or undesirable currents can ow through these devices’
ground wires if more than one device is connected to earth ground. Ensure only one
earth ground is used.
Isolated Ground
The motor common (black) wire is isolated from the motor housing. There is an internal
connection between the motor housing and the cable shield (bare wire) which is a
capacitive coupling (220nF, 63V) with the common (black) wire. If the black lead is
connected to the shield, EMC will not be affected. This can be done at the customer
input end of the cable.
Using The 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. The
frequency range is 0-200Hz. To convert the tachometer output to rpm, multiply the
frequency 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.
CAUTION
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.
CAUTION
NOTE
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.

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.
Starting or running the pump with the discharge valve closed will
overload the motor resulting in overpressure in the discharge pipe.
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.
Operation
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 4mA or turn the
manual control fully anti-clockwise.)
2. Set the power supply (24 VDC to max 30 VDC) to ON. With the control input set to
0 VDC, 4mA or the manual control turned fully anti-clockwise, the pump will show a
nominal 40mA to 70mA 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.
Shut-down Procedure
Switch off the I-Drive by rst setting the external control signal input to the minimum
value, then switch off the power supply. Check that the unit runs down in a steady
manner. 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.
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.
CAUTION
Ensure the pump head temperature does not exceed the ash point
temperature of the uid or area.
Two-wire mode is available on the 0 to 5 VDC control models. To run the
motor in two-wire mode, the control (white) wire can be connected to the
positive supply (red) wire. The motor will run at its maximum speed. The
speed control will not be damaged if the applied voltage is within +/-30 VDC of
the common (black) wire, though maximum speed is achieved at +5 VDC or
higher, and the motor will stop if 0 VDC or lower is applied.
NOTE

DOC No: 7936 REV D
The drive enclosure is rated to IP55. The enclosure rating is maintained
by using the manual control cover screw and seal. After adjustment,
these components must be replaced and secured to the proper torque
in order to maintain the enclosure rating and protection of internal drive
controller.
Manual Control Adjustment
Manual Control Adjustment
If your drive is equipped with the manual control option, the speed of the drive is
controlled by local adjustment of an internal potentiometer. To adjust the speed set point:
1. Remove and retain the M3 cover screw (1) using a small screwdriver.
2. Remove and retain the screw seal (2).
3. Insert a small screwdriver (3) into the access hole and engage the potentiometer
adjustment screw. To increase speed, rotate the adjustment clock-wise. To decrease
speed, rotate the adjustment counter-clockwise. The potentiometer is equipped with
a slip coupling which will allow the user to continue to turn the adjustment screw after
maximum and minimum speed is reached.
4. When adjustment is complete, replace the screw seal (2) and (1) the cover screw.
Tighten the cover screw to 6 in-lb (678 mNm).
CAUTION

DOC No: 7936 REV D
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 effect
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 I-Drive motors are designed to be maintenance free and, apart from manual
speed control models, 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.
NOTE
Magnet Decoupling
The I-Drive 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 housing temperature exceeds
80°C (176°F).
