Set Rotation Direction; Resume; Overload Indicator - Cole-Parmer SD Mode D'emploi

If TORQUE display mode is active, the torque value in the digital display will be 0 and four
decimal points will be flashing.
The mixer shaft is then placed into the solution being mixed. The reading on the display
2.
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 ZERO TORQUE feature is engaged, the maximum torque limit that can be set is adjusted
so that the absolute torque does not exceed the torque of the mixer. Example: The High Torque
limit is set at 65 Ncm, and the mixer is running with an actual torque reading of 20 Ncm. When the
ZERO TRQ button is pressed, the maximum High Torque limit that can be set would be 60 Ncm
(80-20). This limit will be displayed when operator is in Torque Limit set mode.

Set Rotation Direction

By default, the shaft will rotate in a clockwise direction when viewed from the motor down the mixing
shaft. To reverse the direction of rotation to counter-clockwise, press the REV button. The REV
LED will illuminate, indicating reverse rotation is engaged. Rotation direction can be changed when
the mixer is in operation and in PAUSE.

Resume

This mixer includes an optional Resume feature. When set, the mixer will resume mixing after a
power failure or when the power has been removed by control equipment (i.e., PLC) or when the
AC power has been cut (i.e. mixer unplugged).
When power is restored, all previous settings are remembered. If there was time remaining on the
countdown, the timer will reset to set value. The digital display will flash the set speed five times,
then the display returns to the display mode (RPM, TIMER, TORQUE) before power was removed,
indicated by the illuminated LED. If the mixer was in operation before power was disconnected,
the set speed will flash five times and then the mixer will automatically ramp up to the set speed to
resume mixing. If countdown timer was set it will restart countdown, and any other set parameters
will be in effect (torque limits, ZERO TORQUE, direction of rotation). The mixer ships from the
factory with Resume disabled.
To turn on Resume, ensure the motor is connected to the controller, the controller is plugged
1.
in and the POWER switch is ON. Mixer is in PAUSE, not rotating.
Press and hold the INCREASE button. Then press the START/PAUSE button. The Resume
2.
LED will illuminate, indicating Resume is active.
To disable Resume, ensure the motor is connected to the controller and controller is plugged
3.
in with POWER switch ON. Mixer is in PAUSE mode.
Press and hold the DECREASE button. Then press the START/PAUSE button. The Resume
4.
LED will turn off, indicating Resume is disabled.

Overload Indicator

Motor overload can result from too much load (torque) on the mixer, a locked motor condition, or
operating conditions causing overheating in the motor or controller. When the mixer is approaching
an overload condition, the speed of the motor may automatically slow in order to reduce the load.
If the overload situation continues, the mixer will stop rotation. Display will show H, the Ncm LED
will flash, and controller alarm will beep continuously. Pressing any button on the controller will stop
the alarm.
Resolve the condition causing too much load or a locked motor. This error must be corrected or the
over-limit warning will sound again when the mixer is restarted.
The mixer will remain stopped until the unit is reset by turning the POWER switch OFF and back ON
again. If the shutdown occurred due to overheating, the mixer will not turn back on until sufficient
time has passed for the mixer to cool. Turn mixer off, wait approximately 30 minutes, then turn
