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.

• 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 and 50007-05 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.

50007-00, -05 STIR-PAK CONTROLLER

The variable-speed controller, Figure 1a and 1b, is used to set the speed of the mixer heads and provides a 100:1 adjustment range.

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, -05 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.

• To stop the mixer head in an emergency, place the FWD-OFF-REV switch in the OFF position or remove the power plug.

• Be sure the SPEED control is fully counterclockwise before the POWER switch is placed in the FWD or REV positions.

• 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.

• Never insert or remove the mixer shaft/impeller while the mixer shaft is rotating.

50008-00 SERVODYNE CONTROLLER OPERATION Power On

An EEPROM permits storage of all previously set parameters including speed, torque, time and calibration constant. Turning the rear-panel mounted ON/OFF switch to the “ON” position energizes the display without running the motor. The display will come up in the last mode operated. Depressing the START button causes the mixer motor shaft to rotate at the previously programmed speed. Depressing the STOP button stops the motor. Changing Display Modes (TIME, RPM, TORQUE) is accomplished by pressing the desired mode button once. Additional operation of the mode button advances operation to the set mode.

Set Run Time The use of the TIME button in conjunction with the INC/DEC buttons permits entry of a desired mixing time. Pressing the TIME button once when already in the time display mode causes the left (minutes) digit to flash, pressing the TIME button once again causes the right two (seconds) digits to flash. During this period the time can be set with the INC/DEC buttons. Pressing the TIME button a third time starts the countdown provided the motor is running; otherwise the display shows the set time. Maximum programmable time is 99 minutes 59 seconds. A “0” programmed time results in continuous motor operation.

Set Motor Speed Depressing the RPM button when in the RPM mode causes the display to flash and read the set motor speed. Use of the INC/DEC buttons changes the desired speed.

Set Motor Torque Limit The TORQUE limit feature provides for the setting of both HI and LO torque limits. Depressing the TORQUE button when in the TORQUE mode causes the first digit of the display to read either on “H” or “L” (for High or Low limit) and the last three digits to flash and read the set limit. Pressing the INC/DEC buttons changes the set torque limit.

Pressing the Torque button once again while the digits are flashing causes the H or L to flash while the set limit digits stop flashing. It is now that the High or Low limit can be selected by pressing either the INC/DEC buttons. Pressing any button other than INC/DEC buttons returns the display to actual torque. If the motor is running while the torque limit is being modified, the previously programmed limit will be in effect until the torque limit mode is exited; then the new limit will take over.

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, the display flashes “HI” 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.

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 is then running with an actual torque reading of 30 oz-in. When the TORQUE ZERO button is pressed, the maximum torque that can be set would be 35 (65-30). Since the set limit of 50 is above this, it will automatically be changed to 35. The operator will see this when the set mode is entered, which will prevent a setting over 35.

An audible alarm will sound and the LED that corresponds to the limit that has been reached will flash when either the preset time or the torque limit is reached. Both the LED and alarm will cycle on and off until turned off by pressing any button other than the INC/DEC buttons.

Note: Before contacting Cole-Parmer or your dealer for repair, try to determine whether the fault is in the controller or mixer head. The best way is to substitute a known good unit, if available, and recheck.
