and Connectors
Figure 1-1. Controls, Indicators and Connectors
A. POWER (ON/OFF) SWITCH: Turns the unit ON or OFF.
B. SPEED KEYS: Sets the speed of the pump. The higher the number, the
faster the speed of the pump. When the speed key is depressed the
smallest speed units change first followed by an increasing rate of change.
C. FLOW DIRECTION KEY: Sets the direction of pump rotation
Clockwise/Counterclockwise. An LED annunciator indicates the
active direction. The motor is brought to a controlled stop before

Section 2 Installation and Setup
• The drive should be mounted on a flat horizontal surface. Up to a
maximum of two (2) Pump Heads can be added for 600 rpm drives or
four (4) Pump Heads for 100 rpm drives.
• The ambient air temperature should not exceed 104° F (40° C) and
adequate air flow should be provided for.
• The drives are provided with a grounded plug. If used in a GFCI
protected circuit, nuisance tripping may occur.
• 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.
• For tubing selection and compatibility, see Tubing Selection Guide
within this flash drive or on the web.
• For Pump Head information, see Pump Head datasheets within
this flash drive or on the web.
• Before cleaning or conducting maintenance on unit remove power
from the drive.
DANGER: High voltages exist and are accessible. Use extreme
caution when servicing internal components.
Mount Pump Head and load tubing (See Pump Head datasheets within
this flash drive or on the web). Check to ensure that rollers are clean and
free of defects.

Inserting Tubing
Section 3 Operation
WARNINGS: Tubing breakage may result in fluid being
sprayed from pump. Use appropriate measures to protect
operator and equipment.
Turn Pump System off before removing or installing tubing. Fingers or
loose clothing could be caught in the pump mechanism.
CAUTION: To avoid electrical shock, the power cord protec-
tive grounding conductor must be connected to ground. Not
for operation in wet locations as defined by EN61010-1.
If the product is not used in a manner specified in the
instructions, the protection provided by the equipment
may be impaired.
Tubing should be inspected periodically for tears, cracks, cut marks,
abrasions, inability to hold pressure, bubbles in the flow stream and
reduction or loss of flow.
Tubing life may be extended by periodically moving the worn tubing inside the
occlusion bed of the pump to the outside of the occlusion bed to the suction
side of the pump. This will avoid excessive tubing wear at any specific point.
Always move the worn tubing to the suction side of the pump.
CAUTION: When changing flow direction, allow the pump
to come to a complete stop before starting again. Failure to
do so could cause permanent damage to the motor.
1. Make sure the speed is set to the minimum setting.
2. Turn the power switch ON. Increase the speed to start the pump
action. The higher the rpm setting, the faster the speed of the pump.
3. The L/S Precision Variable-Speed Modular Drives are self-priming. The L/S
Precision Variable-Speed Console Drives are self-priming. To begin pumping,
select a flow direction with the flow direction button, insert the intake and
output tubing into a reservoir, and turn the unit ON. Prime the tubing for at
least 5 minutes. If accurate flow control is important, allow the pump to
prime for approximately 20 minutes for more stable flow conditions.
NOTE: When in INTernal mode, pump will start automatically after
brownout, powerout or if drive was turned off using the power switch
while pump was running.

L/S Precision Variable-Speed Modular Drives Operating Manual 3-3Masterflex
Section 3
Operation
The front INT/EXT key enables external functions. Switching to INT on
the display disables the external functions, allowing the front panel
controls to operate the pump.
When the INT/EXT key is in the EXT position, starting and stopping
thepump is controlled by an external contact closure between pins 6 and 7
(Jumper B) (pins 4 and 8 for NEMA 4X models), and the pump speed
isdetermined by an externally supplied 0–10V or 4–20 mA source.
Connection must be made between pins 6 and 7 (pins 4 and 8 for NEMA
4X models) to Start/Stop the drive and a control voltage greater than 0V
between pins 1 and 3 (pins 1 and 5 for NEMA 4X models) or a control
current greater than 4 mA between pins 2 and 3 (pins 3 and 5 for NEMA
4X models) must be applied for the pump to run.
If setting the speed from the front panel is desired with external Start/Stop
contact operation, the INT/EXT key must again be in the EXT position. In
addition, Jumper A should be in place. Jumper A connects pin 4 (pin 14
for NEMA 4X models) of the “D” shell connector (Local/Remote) to pin 5
(pin 10 for NEMA 4X models) (Local/Remote Reference). Start/Stop will
then be controlled from the rear panel (Jumper B), and the pump speed
will be controlled from the front panel.
NOTE: The signal common for the speed control voltage and current
inputs is not referenced to earth ground.
The START/STOP, CW/CCW and Local/Remote are digital inputs. They
are internally pulled up to +5 V with respect to earth ground via pins 5
and 6 (pins 8 and 10 for NEMA 4X models). They can alternately be
driven with open collector logic. For increased noise immunity, use of
contact closures is recommended.
WARNING: A contactor or other device that routinely disconnects
and reapplies the AC line to the drive to start and stop the motor
can cause drive hardware damage. The drive is designed to use
control input signals that will start and stop the motor.
