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

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 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.

CAUTION: To avoid electrical shock, the power cord protective
grounding conductor must be connected to ground. Not for
operation in wet locations as defined by EN61010-1.

CAUTIONS: Keep fingers away from magnetic coupling while pump

Introduction

The Masterflex Digital Gear Pump Drive provides the ability to mount a
Masterflex Gear Pump Head to achieve the features of a digital dispensing
and metering pump system. Features include a small footprint, plus drives
that are stackable.

The Masterflex Digital Drive 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 100-to-1,
bidirectional flow and self-priming capabilities allow for smooth, seamless
operation and an extremely broad flow range.

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.

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

This Masterflex Drive with its high turndown, superior accuracy, and
intuitive interface make it ideally suited where precise and repeatable flow
control is required. The pump accommodates a variety of product fill
volumes and batch dispensing profiles.

NAVIGATION: From the Main Menu or SETUP Menu select REMOTE
CONTROL and ENTER.

LOCAL: When this is selected the drive is controlled by the front panel
keypad, Start/Stop Input, Directional Input or Prime Input.

CURRENT INPUT: When this is selected, the drive is in remote control.
This allows the user to input a current signal to control the flow. The user has
an option to adjust the minimum, maximum and middle set points for
current and flow. By default the minimum (MIN) current is set to 4.2 mA
and the flow is set to 0. The maximum (MAX) is set to 20 mA and the flow is
set to maximum. The middle (MID) is auto calculated for a current and flow
that is centered between the MIN and the MAX. The MID can be adjusted if
other profiles are needed. The scaling can be inverted if necessary. To confirm
CURRENT INPUT MODE is selected, select EXIT after returning to the
Remote Control Menu, then select CONTINUOUS PUMP MODE. To
deselect Remote Current Input Mode select LOCAL and ENTER.

NOTE: When Current Input is selected the drive will not start until the
REMOTE CONTROL MODE is exited and CONTINUOUS PUMP
MODE is selected.

CURRENT OUTPUT: This allows the user to adjust the current output for a
given flow. The user has an option to adjust the minimum, maximum and
middle setpoints for current and flow. By default the minimum (MIN) flow is set
to 0.00 and the current is set to 4.0 mA. The maximum (MAX) is set to
maximum flow and the current is set to 20.0 mA. The middle (MID) is auto
calculated for a current and flow that is centered between the MIN and the MAX.
The MID can be adjusted if other profiles are needed. This allows for a three­point calibration of the current output. The flow is linear between these points.
The scaling can be inverted if necessary. NOTE: Selecting Current Output will not
put user into REMOTE CONTROL MODE. Only selecting VOLTAGE
INPUT or CURRENT INPUT will put the user into Remote Control Mode, as
indicated by the empty house icon (see position G, Figure 3-2). NOTE: The
Current Output indicates the Running Command Speed. Use the Motor

is set to 00.00 and the voltage is set to 00.0V DC. The maximum (MAX) is
set to maximum flow and the voltage is set to 10.0V DC. The middle (MID)
is auto calculated for a voltage and flow that is centered between the MIN and
the MAX. The MID can be adjusted if other profiles are needed. This allows
for a three point calibration of the voltage output. The flow is linear between
these points. The scaling can be inverted if necessary. NOTE: Selecting Voltage
Output will not put the user into Remote Control Mode. Only selecting
Voltage Input or Current Input will put the user into Remote Control Mode,
as indicated by the empty house icon (see position G, Figure 3-2). NOTE: The
Voltage Output indicates the Running Command Speed. Use the Motor
Running outputs to indicate if pump is running.

START/STOP: The START/STOP input can be configured to be OFF
(factory default), or ON for the drive to run.

With the OFF selected (factory default), use of the START/STOP input is
optional. When the START/STOP input is open, the drive can still be started
using the START/STOP key, PRIME key, or PRIME input. In remote modes
the drive will also run if there is sufficient current or voltage at the input.

Closing the START/STOP input will cause the drive to run until the
START/STOP input opens or the START/STOP key is pressed. In Time
dispense, Copy dispense, and Volume dispense mode, only a momentary
START/STOP closure is needed to start the drive. If the drive is already
running in one of the dispense modes, a momentary START/STOP
closure will stop the drive. In SET COPY MODE, the START/STOP
input functions the same as in CONTINUOUS MODE; closing it will
cause the drive to run until it opens.

to the Remote Start/Stop input causes the drive to run, while a continuous
active low to the Remote CW/CCW input causes the drive to run CCW.
The motor is brought to a controlled stop before reversing direction. A
continuous active low to the Remote Prime input causes the drive to run
at full rated speed.

Section 3

Operation

Some remote outputs on this drive (Tachometer, Local/Remote, and
Alarm) are “open collector” type outputs and cannot be wired in the same
manner as relay outputs. An open collector output is not isolated and
must be configured differently than a relay output.When the open
collector output is active, the output is effectively switched to earth ground
and if improperly terminated could result in damage to the drive and/or
external equipment.

Recommendation

When connecting to open collector outputs, the output should be
connected to a current limiting resistor and then to a positive supply
source which is less than 28V DC. Typically this would be connected to a
24V PLC input (see Figure 3-14).

NOTE: when using the 24V supply on the interface connector, current
draw must be limited to 150 mA.

NOTE: DO NOT connect 120V supply lines to open collector outputs!

WARNINGS: 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: 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.
