SAFETY PRECAUTIONS
•High voltages exist and are accessible in the controller.
Contact Cole-Parmer for servicing.
•Do not operate mixers where explosive vapors or flammable
materials exist. Death or serious injury could result. Check
NEC and local codes before installing.
-- 2 --
•Never clean the controller or mixer head while power is
applied to the system.
•Use only those mixer shafts that are properly sized for the
mixer head being used. Refer to mixer head specifications for
the proper shaft diameter or range to be used. Sizes other than
those specified can cause injury to personnel or damage to
equipment.
•Disconnect the AC power input line cord before connecting the
mixer head cable.
•Exercise extreme care when adjusting mixer height and/or
position to avoid personal injury. Never make these
adjustments while the mixer shaft is rotating.
•Never insert or remove the mixer shaft/impeller while the mixer
shaft is rotating.
•Be sure speed control is fully counterclockwise before the
POWER switch is placed in the FWD or REV positions. (50007-
00 Controller)
•Check that all cords are clear of any moving parts and not
subject to splashes or spills.
•Use care when setting the operating speed of the mixer.
Operation at high speeds in small mixing vessels could result
in hazardous splashing on the operator and equipment.
•When running at full speed and load at higher ambient
temperatures, the mixer head may get very hot to the touch.
•Use of mixing shafts and impellers larger than those
recommended could result in poor product performance and
shortened service life.
•Mixer shafts must be inserted into high-speed through-shaft
mixers at least 3 inches (8 mm) and the collet hand-tightened
firmly to ensure adequate shaft retention. Keep mixer shafts as
short as possible to reduce resonant vibrations caused by the
shaft flexing at higher speeds.
•The mixer head is to be used only for mixing. It is not intended
for any other purpose.

CONTROL
Figure 1a: Display and Controls
The controller ensures accurate, dependable motor speed (mixing) control, with “soft-start” and smooth, gradual
adjustment to the speed setting. Constant speed with a 100:1 adjustment range is maintained electronically via
automatic compensation for changes in load torque demands at both high and low speeds. Built-in motor current
compensation minimizes speed drift with changes in load. Motor current limiting protects the system in case of a
locked rotor condition. Output circuit protection protects against inadvertent output shorting. Mixer rotation is
reversible.

50007-00 STIR-PAK CONTROLLER OPERATION
FWD-OFF-REV Switch
In the FWD position, the shaft will rotate in a
counterclockwise direction when viewed from
the impeller.
The center or OFF position removes power from
both the controller and mixer head.
In the REV position, the shaft will rotate in a
clockwise direction when viewed from the
impeller.
POWER Indicator
The green LED indicator illuminates whenever
the FWD-OFF-REV switch is in either the FWD
or REV position.
SPEED Control
The SPEED control precisely sets the output speed of the shaft. The controller has a range of 100:1
depending on the model; shaft speed can be as low as 2RPM or as high as 6000RPM.
Slowly adjust the SPEED Control from the 0 position to a setting that provides the desired mixing speed.
Always return the speed control to the 0 position when mixing is complete.
Note: With new mixing heads, allow approximately 20 minutes run-in time to allow warm-up drift to
become minimal.

Regardless of the set torque limit, there is always a maximum torque limit check to guard
against motor overheating. If this limit is exceeded, the motor stops, the alarm sounds and the
in-oz LED flashes. Pressing any key causes the display to return to what was previously
displayed before the alarm. The error must be corrected or the over-limit warning will sound
again when the motor is restarted.
Set Torque Zero
The TORQUE ZERO button is used to zero the torque display so that the actual torque necessary
to mix something can be read directly on the display. To use this feature, the TORQUE ZERO
button is pressed while the mixer head shaft is running in free air; the display will zero. The mixer
shaft is then placed into the solution being mixed, the reading on the display will now indicate the
torque necessary to mix the solution. This number can now be used to determine the proper shut
off or torque limit when mixing several batches of the same consistency.
When the TORQUE ZERO button is operated, the maximum torque limit that can be set is
adjusted so that the absolute torque does not exceed the continuous torque of the mixer head
being used.
Example: The operator has set a high torque limit of 50 oz-in for a motor rated for 65. The motor
set limit of 50 is above this, it will automatically be changed to 35. The operator will see
