SAFETY PRECAUTIONS
DANGER: High voltages exist in the Drive/Controller.
WARNING: Disconnect the AC power input line cord before connecting
the drive motor cable.
WARNING: No user serviceable parts are inside of this controller. Refer
servicing to your dealer.
SETUP AND DRIVE OPERATION
INTRODUCTION AND GENERAL DESCRIPTION
This controller and drive system, when coupled with a MASTERFLEX®I/P®-compatible
Pump Head, provide variable-flow fluid transfer. The motor and controller can be
mounted in separate locations for better protection or control. Select from Benchtop or
NEMA-rated controllers. The NEMA-rated motor and controller withstand wet or hostile
environments and can operate manually or remotely via a 4–20 mA input signal.
VARIETY OF PUMP HEADS ACCEPTED
Mount up to 2 MASTERFLEX®I/P®Pump Heads and all MASTERFLEX®I/P®-compatible Pump Heads (up to rated torque). See individual Pump Heads for flow rates.
SETUP AND DRIVE OPERATION
1. Unpack the drive, save packing material until proper product operation has
been verified.
2. Mount Pump Head and load tubing (see Pump Head manual).
3. Connect the drive motor cable to the cable from the controller.
4. Connect the AC power input line cord to the AC receptacle.
5. Selecting motor direction turns pump on. The LED indicator turns GREEN.
6. Adjust flow rate with speed control potentiometer.
OPTIONAL: WALL MOUNTING (7591-10, -15 only)
The NEMA controller is furnished with a 24-ft. long CONTROLLER CABLE for
convenient wall mounting away from the pumping operation.
1. Select a mounting location. The 4 brackets
(furnished) can be installed vertically or
horizontally in the enclosure slots, as shown,
to help accommodate any space limitations.
2. Use the accompanying bolts and lockwashers
to secure the brackets to the NEMA enclosure.
WARNING: PRODUCT USE LIMITATION
This product is not designed for, nor intended for use in patient
connected applications; including, but not limited to, medical and dental use,
and accordingly, has not been submitted for FDA approval.

REMOTE OPERATING PROCEDURE (7591-10, -15 only)
WARNING:
Turn off AC power before connecting the external remote
control cable.
1. Connect the remote speed control to the terminal strip on the bottom of the
controller. (See Figure 1.)
2. Set the front panel CONTROL switch to the EXTERNAL position.
NOTE: When the CONTROL switch is in the EXTERNAL position, motor speed
can be controlled only from the external source. The front panel speed
control is inoperative.
3. Set the front panel DIRECTIONAL switch for the desired direction of rotation.
4. Set the speed control on the remote control to a setting that will provide the
desired flow rate and lock the control.
5. 4–20 mA loop control:
<4 mA (stop pump)
4 mA (minimum speed)
20 mA (maximum speed)
± 3% linearity control
1.8 V DC (nom.) input voltage drop
> 250 V isolation potential
NOTE: The speed control can be adjusted at any time, either before starting the
drive or while the drive is running.

MAINTENANCE
CLEANING
Keep the drive enclosure clean with mild detergents. Never immerse or use
excessive fluid.
MOTOR BRUSH CHECK/REPLACEMENT
NOTE: Brushes should be checked every 6 months or 2000 operating hours.
1. Place the FWD-OFF-REV switch in the OFF position.
2. Disconnect the AC line cord from the AC receptacle.
3. Disconnect the motor cable from the controller.
4. Remove the two rubber caps (see Figure 2), then carefully unscrew each
brush cap on opposite sides of the motor. Withdraw the brush, and examine it
for wear.
NOTE: Replace both brushes if either brush is less than 0.300 in (7.6 mm) long
from base to point.
5. Screw brush caps into brush holder on each side of motor and replace rubber
caps.
6. Connect motor to controller.
7. Connect AC line cord to AC receptacle.
