Safety Precautions

Preface

SAFETY

PRECAUTIONS

DANGER: High voltages exist and are accessible. Use extreme caution when
servicing internal components.

WARNINGS: Tubing breakage may result in fluid being sprayed from pump. Use

!

appropriate measures to protect operator and equipment.

Turn drive off before removing or installing tubing. Fingers or loose clothing
could get caught in drive mechanism.

WARNINGS: Do not operate the pump drive in a manner not specified in the
documentation. Misuse of the pump drive may result in a hazard and may
compromise the safety protection built into the pump drive. If the pump drive is
damaged, turn it off and not use it until service-trained personnel can check
its safety.

Single-Phase Only. Not to be used with Split-Phase lines.

The Power switch on the Back Panel is not the main disconnect. Main
disconnect is accomplished by disconnecting the detachable power supply
cord at the appliance coupler or at the main plug. Ensure the power cord is
easily accessible and removable, in the event of an emergency, which requires
immediate disconnection.

The operator should check the detachable power supply cord condition. The
equipment should not be operated if the power supply cord is cracked or
broken. Any obvious damage to the enclosure (from a drop or fall) should be
checked by service personnel for loose or damaged parts inside.

CAUTIONS: Power must be turned off before connecting the external remote

!

control cable to prevent damage to the drive.

Do not contaminate the lubricant in the container, on the shaft or on the seal
with foreign material. Failure to observe this precaution may result in damage
to the seal and premature failure of the seal.

No foreign matter should be allowed under the gasket on the back of the front
plate or under the heads of the screws. Failure to observe this precaution may
result in leakage during wash down of the drive.

Do not block the rear panel of the pump drive. The power switch must always
be easy to access. The power cord must always be easy to disconnect.

Replace the power cord only with one of the same type and rating. The
minimum power ratings are stated on the rear panel.

The 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.

When using hazardous chemical and biological agents, take all suitable
protective measures, such as wearing protective glasses and gloves resistant
to the substances used. Follow local and/or national regulations for safe
operation and maintenance of the system.

Section 1

Introduction

General Description

e MASTERFLEX Digital Peristaltic Pump Drives offer flow rate
capacities from 0.001 mL/min to 19 L/min using MASTERFLEX Stan-

dard, EASY-LOAD® or High-Performance Pump Heads. Even lower flow
rates can be achieved with our multichannel and cartridge Pump Heads.
Features include a small footprint, plus non-stainless steel drives that are
stackable.

e MASTERFLEX digital pump provides a motor speed repeatability of
+/-0.1 percent to maximize productivity in precision liquid dosing, batch
dispensing and filling applications. A turndown ratio up to 6500-to-1,
bidirectional flow and self-priming capabilities allow for smooth, seamless
operation and an extremely broad flow range within one tubing size.

In addition to high accuracy, precision, repeatability and resolution of
speed (or flow rate), the MASTERFLEX drive features a multi-language,
intuitive, man/machine interface with a four-line graphical LCD display
providing direct readout of pump speed (rpm), flow rate (user-selected
units), number of dispenses, and menu options.

e easy-to-use keypad eliminates setpoint overshoot and provides easy
navigation through menu options that include a number of on-screen
programming features.

ese drives use high precision, no-maintenance brushless motors for
improved reliability. is, combined with its high turndown, superior
accuracy, and intuitive interface make the MASTERFLEX drives ideally
suited where ultra-precise, repeatable flow control is required. e pump
accommodates a variety of product fill volumes and batch dispensing pro­files, and fluid only contacts the tubing, providing for contamination-free
pumping.

MASTERFLEX pumps are self-priming, can operate dry without damage,
are suitable for most chemicals and contain no valves or seals. See Pump
Head and Tubing Guides within this CD.

Section 2 Installation and Setup

• e drive should be mounted on a flat horizontal surface, and no more
than two (2) Pump Heads should be added for 600 rpm drives or four
(4) pump Heads for 100 rpm drives.

• e ambient air temperature should not exceed 104° F (40° C) and
adequate air flow should be provided for.

CAUTION: Do not block the rear panel of the pump drive. The power
switch must always be easy to access. The power cord must
always be easy to disconnect.

• Tubing should be clean and routed so that bend radii are at a
minimum four (4) times the tube diameter and as short as possible.

WARNING: Turn drive off before removing or installing tubing. Fingers
or loose clothing could get caught in drive mechanism.

• Use a tube size of appropriate diameter for the flow rate and viscosity
required.

• To maintain the best accuracy of flow rates, re-calibrate tubing regularly.
See Tubing Calibration Section of this manual.

• For tubing selection and compatibility, see Tubing Selection Guide within
this CD.

• For Pump Head information, see Pump Head information within this CD.

• When cleaning or performing maintenance, please remove power from

field will be highlighted. Press the ENTER key and adjust the CAL
VOLUME to the measured quantity. Use the LEFT/RIGHT keys to
select digit to be changed, use the UP/DOWN keys to adjust the value,
and press ENTER to SAVE setting and EXIT the field.

A lower case “c” should now be displayed when the calibrated tubing
size is selected. e volume units will depend on the flow rate units. e
flow rate unit mL/min will result in a volume unit of mL; oz/min will
result in a volume unit of oz.

Tubing Calibration Notes

• If the drive is stopped during calibration, empty the container and re­start the procedure.

• Calibration time at maximum allowable flow rate (default max flow
rate) is 5-10 seconds and at minimum allowable flow rate (approxi­mately 4% of the maximum flow rate) is 4 minutes. Select the
CUSTOM tube size for other tubing sizes or lower flow rates.

• Minimum and maximum flow rates will change after a tubing cali­bration due to a re-calculation of the vol/rev.

• Optimum results are best obtained after tubing has been broken in by
running in pump for at least 10 minutes. Steps 8-10 can be repeated
as necessary to optimize the accuracy of the tubing cal.

CAL RUN TIME FORMULA

60 / (flow rate [mL/min] / cal volume [mL]) = cal run time (seconds)

INVALID CAL RUN TIME EXAMPLE

• tube size 13 flow rate range is 0.006 mL/min – 36.0 mL/min

• at flow rate of 1 mL/min, cal run time calculation is as follows:
60 / (1 mL/min / 6 mL) = 360 seconds 360 seconds exceed the max

run time of 4 minutes (240 seconds)
