Safety
1. Read instructions before operating the unit.
2. Observe safety precautions at all times, especially when pumping
dangerous liquids.
3. If the pump runs unusually noisy or if bunching of the tubing in the
pump can be observed, make sure the tubing is clamped down tightly
and/or replace it with a new piece of tubing.
4. The L/S Precision Variable-Speed Console Drives must be wellgrounded at all times.
5. The L/S Precision Variable-Speed Console Drives are equipped with a
current-limiting circuit that will shut the motor down if any of the
following conditions exist:
a. Tubing that is too hard is loaded in the pump.
b. Incorrect tubing size or wall thickness is loaded in the pump.
c. Tubing is improperly loaded into the Pump Head.
6. The unit is fused and grounded to protect the operator in the event of
short circuits that could be caused by liquid entering the case.
CAUTION: Replace the fuse only with one of the same type
and rating. The fuse rating and type are stated on the
rear panel.
7. The L/S Precision Variable-Speed Console Drives should not be used
in outdoor or hazardous locations.

•
Low shearing for handling the most shear sensitive of fluids such as
latex or fire fighting foam.
•
Capable of running dry and pumping fluids with high quantities of
entrained air, such as black liquor soap.
•
High volumetric efficiency allows operation in metering or dosing
applications where high accuracy is required.
•

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
reversing direction.
D. INTERNAL/EXTERNAL KEY: Changes the drive operation mode.
Internal (Local) operation from the front panel keypad is designated
by INT, external (Remote) operation is designated by EXT. In INT
mode, START/STOP, FLOW DIRECTION, and SPEED keys on the
front panel determine operating state. Depression and release of keys
enables toggling between the two operating states.
E. START/STOP KEY: Upon depression, key toggles the motor
ON/OFF during INT mode. This key will not start the drive if in
EXT mode. If pressed while operating in EXT mode (stop desired),
the button will always stop the drive and a toggle of the EXT
Start/Stop is required to restart the drive.
F. EXTERNAL/REMOTE CONNECTOR: Utilized to connect wiring
for remote control operation with a DB9 connector.
G. IEC Power Entry Module/Line Cord: Utilized to connect line cord to
drive. See page 4-1 for alternative cords.

Before Starting Drive
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 300 rpm and 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 CD.
•
For Pump Head information, see Pump Head datasheets within
this CD.
•
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.
Mounting the
Pump Head
Cole-Parmer
Mount Pump Head and load tubing (See Pump Head datasheets within
this CD). Check to ensure that rollers are clean and free of defects.

Section 3
Inserting Tubing
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 protective 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 Inspection and
Replacement
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.
Pump Controls
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 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.

External Operation
Press and hold the INT/EXT key. After five (5) seconds, display will
change to all dashes. Release INT/EXT key and press UP ARROW key (▲)
five (5) times. Repeat this process to unlock the keypad. When the keypad
is locked out, display will change to display all dashes (- - - - -) when a key
is depressed.
Models are equipped with inputs that can be controlled by external signals
connected at the rear panel 9-pin “D” shell connector. The external inputs
permit control of the pump by remote equipment or accessories. Figure 3-1
indicates the signal locations in the connector.

Section 3
Operation
External Inputs
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 the
pump is controlled by an external contact closure between pins 6 and 7
(Jumper B), and the pump speed is determined by an externally supplied
0–10V or 4–20 mA source. Connection must be made between pins 6 and
7 to Start/Stop the drive and a control voltage greater than 0V between
pins 1 and 3 or a control current greater than 4 mA between pins 2 and 3
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 of the
“D” shell connector (Local/Remote) to pin 5 (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. The accessory
Footswitch (part no. 77595-35) and Handheld Remote Controller
(part no. 07528-80) are connected internally in this way.
NOTE: The signal common for the speed control voltage and current
inputs is not referenced to earth ground.
The START/STOP (pin 7), CW/CCW (pin 8) and Local/Remote (pin 4)
are digital inputs. They are internally pulled up to +5 V with respect to
earth ground via pins 5 and 6. They can alternately be driven with open
collector logic. For increased noise immunity, use of contact closures is
recommended.
