SECTION 1: INTRODUCTION
SAFE OPERATION
e Masterex I/P MasterSense™Process Drive is designed for pumping and dispensing applications in
laboratory and process environments. Conrm that the pump drive is operated only in the manner specied
in this operating manual and that safe work practices and Good Laboratory Practice (GLP) are followed.
Misuse of the pump drive may compromise built-in safety protections and result in injury and/or damage to
equipment. Do not operate the pump drive with water on the surface of the touchscreen.
e following Safety Symbols are used in this documentation:
!CAUTION: Risk of Danger. Consult Operating Manual for nature of hazard and corrective actions.
CAUTION: Risk of crushing. Keep ngers away from the rotor while the pump is in operation.
Stop pump before loading or unloading tubing.
CAUTION: Hot Surface. Do not touch.
CAUTION: Risk of electric shock. Consult Operating Manual for nature of hazard and corrective
actions.
Please observe the following cautions and recommendations:
!CAUTION: Do not operate the pump in a way that exceeds the designed operating and environ-
mental conditions outlined in this operating manual.
!
CAUTION: e pump must not be used:
• As a medical device.
• In explosion proof chambers or in the presence of ammable gases or fumes.
CAUTION: e circuit between the mains power supply and the pump must be connected to
earth ground.
CAUTION: Turn the drive o before removing or installing tubing. Fingers or loose clothing
could get caught in the drive mechanism.
!CAUTION: Do not open or remove the housing while the pump is operating.
!CAUTION: Tubing can tear and burst during operation. It is the responsibility of the customer to
take the necessary precautions to avoid injury or damage to equipment.
!
CAUTION: It is recommended that any repairs be performed only by an authorized technician.
If service and repairs are performed by the customer or by any third party company, Masterex
denies all responsibility.
CAUTION: Sheilded cable must be used when connecting to the Ethernet port.

ABOUT THE MASTERFLEX I/P MASTERSENSE™
e Masterex I/P MasterSense™Process Drive oers precise ow control and highly accurate uid
dispensing ideal for pumping high viscous and shear-sensitive liquids. ese pumps are also ideally suited
for use where sterile conditions and purity are required. Toxic and hazardous uids can be pumped with the
proper selection of tubing since the uid contacts only the tubing and not the pump. All I/P precision drives
include a highly accurate, maintenance-free motor and an easy to navigate touchscreen that makes setup and
operation easier than ever. e I/P range features Ethernet and Wi-Fi connections for web-based monitoring
using the MasterexLive website (see www.masterex.com), and remote analog input control and monitoring
through the pump drive’s 31-Pin female connection port.
Package Contents
NOTE: Please check the package and its contents for any visible signs of damage. If any damage is found
please contact Technical Assistance immediately (see "Technical Assistance" on page 5-8).
• Pump Drive
• OHS Cable
• Quick Start Guide
• Flash Drive Containing the Operating Manual
Features
• A 7-inch multi-language touchscreen display providing easy access to user-dened operation parameters
and direct readouts of pump operation data, including pump speed, ow rates, ow direction, and batch
totals.
• Volume, Time, Continuous, and Analog Input modes for quick and easy operation.
• User selectable dispense volumes, tube diameters, ow rates, pump speeds, and run times.
• Easy user management with three levels of access: ADMIN, SUPER USER and USER.

BEFORE STARTING THE DRIVE
!CAUTION: Do not block the rear panel of the pump drive. e power switch must always
be easy to access and the power cord must always be easy to disconnect.
CAUTION: Turn the drive o before removing or installing tubing. Fingers or loose cloth-
ing could get caught in the drive mechanism.
!
CAUTION: e power cord set supplied with your pump drive meets the requirements
of the country where you purchased the pump drive. If you use the pump drive in another
country, you must use a power cord set that meets the requirements of that country.
CAUTION: To avoid electrical shock, the power cord protective grounding conductor must
be connected to ground. Not for operation in wet locations as dened by EN61010-1.
• Ensure the pump drive is mounted on a at surface.
• Ensure adequate air ow around the pump drive and ensure that the ambient air temperature does not
exceed 104° F (40° C).
• Tubing should be clean and routed so that bend radii are at a minimum of four (4) times the outside tube
diameter and are as short as possible.
• Use the appropriate tube diameter for the required ow rate and viscosity.
• Recalibrate tubing regularly to maintain the best ow rate accuracy (for further information see "Tube
Calibration" on page 2-11).
•For tubing selection and compatibility go to www.masterex.com.
•Unplug the pump drive’s power cable from the mains power outlet when cleaning or performing
maintenance on the drive.
SWITCHING ON THE DRIVE
1. Plug in and securely fasten the supplied power cable to the IEC Connector located at the rear of the drive.
2. Plug the opposite end of the power cable into a mains power outlet.
3. Switch the drive on using the power switch located at the rear of the drive. NOTE: e drive takes
approximately two minutes to complete start-up.
NOTE:
• On the initial start-up the Language Settings Screen will be displayed. A language must be selected before
pump operation (for further information see "Language Settings" on page 2-4).

Example Flow System
To prime the pump drive:
1. Insert the tubing into the pump head (refer to the pump head user manual for further information).
2. Insert the tube inlet into the supply uid.
3. Insert the tube outlet into an appropriate container.
4. Switch the drive on using the power switch located at the rear of the drive. NOTE: If Manage User
is enabled you may be prompted for a username and password (For further information see "User
Management" on page 2-8).
5. Navigate to the Continuous, Time or Volume Mode screens.
6. Press and hold PRIME until there are no bubbles visible in the tubing. Priming will stop when

TUBE CALIBRATION
To ensure accurate dispensing of uids, tube calibration should be performed whenever uids, ow rate or
tubing is changed. Tube calibration can be accessed from the Continuous Mode Run Screen or from either of
the Volume or Time Mode Edit screens.
Tube Calibration Screen
General Preparation:
• Conrm the correct tubing has been selected and is properly loaded into the pump drive (refer to the
pump head user manual for further information).
• Ensure the correct pump head and tube size have been selected (for further information see "Pump Head
Selection" on page 2-9).
• Conrm all uids and containers are ready.
To calibrate tubing:
1. Insert the tube inlet into the supply uid.
2. Insert the tube outlet into a suitable container. NOTE: e container should be placed on a scale for
increased accuracy. If using a scale, an acceptable weight to volume conversion for water is: 1 g = 1 mL.
3. Switch the drive on using the power switch located at the rear of the drive. NOTE: If User Management
is enabled you may be prompted for a username and password (For further information see "User
Management" on page 2-8).

12. Tap START to begin calibration. NOTE: Calibration progress will be displayed on the touchscreen.
13. When calibration is complete use the onscreen keypad to enter the measured volume of uid from the
tube outlet container.
14. Tap CONFIRM to complete calibration and return to the previous mode screen. Calibration
Complete should now be displayed to indicate that calibration has been completed for the current
tube size, tube volume, and ow rate.
NOTE:
• e estimated accuracy for the selected calibration settings is shown in the Calibration Strength Bar on
the Tube Calibration Screen. Calibration accuracy can be improved by using a larger calibration volume
and/or altering the ow rate.
• Calibration settings are retained and transferred to other mode screens when entering or leaving the Tube
Calibration Screen.
• If the drive is stopped during calibration the calibration will be discarded and the previous mode screen
will be displayed. Empty the container before restarting the procedure.
• Calibration time at the maximum allowable ow rate (default max ow rate) is approximately 10 seconds.
Calibration time at the minimum allowable ow rate (approximately 4% of the maximum ow rate) is 4
minutes.
• Minimum and maximum ow rates will change after calibration due to a recalculation of the volume of
uid per pump revolution.
• e best results are obtained after tubing has been run in the pump for approximately 20-30 minutes.
• Steps 9–14 can be repeated as necessary to optimize the accuracy of the tubing calibration.
