Set Torque Limits; Set Zero Torque - Cole-Parmer SD Mode D'emploi

New set time will flash for five seconds, then be accepted as new time. Pressing START/
5.
PAUSE button will also accept new time. If mixer is in operation, the display stops flashing
and begins timer countdown. If mixer is in PAUSE, the display stops flashing and shows new
set time.
When the countdown of the timer is completed, the mixer stops rotation. The MIN LED will flash
and controller will beep continuously until any button on the controller is pressed. The set time is
remembered after countdown is completed.

Set Torque Limits

The TORQUE display mode is active when Ncm LED is illuminated. The digital display will show
actual torque, so if the mixer is in PAUSE the display will show 0. Torque limits can be set both
when the mixer is in operation and in PAUSE. Default limits for the High Torque is 80 Ncm, while
the Low Torque is 0 Ncm.
The TORQUE limit feature allows customizing high and low torque limits for precise monitoring
of mixing processes. This mixer can set either the High or Low Torque limit, or have both limits
simultaneously in effect for a controlled allowable range. The minimum range between High and
Low Torque limits is 5 Ncm. Attempting to set a torque limit within 5 Ncm of the other limit will result
in ER code being displayed.
When in the TORQUE display mode, press the TRQ button. Display will show H in the left of
1.
the display, and flashing digits to the right, indicating the High Torque limit can be adjusted. To
reset High Torque limit to default value, press and hold TRQ button for two seconds.
Use the INCREASE and DECREASE buttons to adjust the High Torque limit as desired. If
2.
High Torque limit is set within 5 Ncm of the Low Torque limit, "ER" flashes in the display
indicating an error. Wait three seconds for "ER" to clear or press the INCREASE button. The
allowable High Torque limit now flashes in the display.
Press TRQ button again. Display will show L in the left of the display and flashing digits to the
3.
right, indicating the Low Torque limit can be adjusted. Pressing the TRQ button repeatedly will
switch the display between High and Low limits. To reset Low Torque limit to default value,
press and hold TRQ button for two seconds.
Use the INCREASE and DECREASE buttons to adjust the Low Torque limit as desired. If Low

Torque limit is set within 5 Ncm of the High Torque limit, "ER" flashes in the display indicating
an error. Wait three seconds for "ER" to clear or press the DECREASE button. The allowable
Low Torque limit now flashes in the display.
The new set Torque limit will flash for five seconds, then both High and Low Torque limits will
5.
be accepted. Pressing START/PAUSE button will also accept new torque limits. If the mixer
is in operation, the display stops flashing and shows actual torque. If motor is in PAUSE, the
display stops flashing and shows 0.
When one of the torque limits is reached, the mixer stops rotation. The Ncm LED will flash and
controller alarm will beep continuously. The display will show an H or an L to indicate which limit has
been reached. Pressing any button on the controller will stop the alarm and LED flashing.
Regardless of the set limits, there is always a maximum torque limit check to guard against motor
overheating. If this limit is exceeded, the mixer stops rotation and alarm will beep. The digital
display will show H and the Ncm LED will flash. Pressing any button on the controller will stop alarm
beeping. This error must be corrected or the overload warning will sound again when the motor is
restarted. The mixer will remain stopped until the unit is reset by turning the POWER switch OFF
and back ON again.

Set Zero Torque

The ZERO TORQUE feature is used to zero the torque display so that the actual torque required for
the mixing process can be read directly on the display. Torque is displayed in Ncm.
While the mixer shaft is running in free air or a reference liquid, press the ZERO TRQ button.
