Equipment and Disposable Description

Note: The Bowl Optics sensors ARE disabled in the manual mode and when using
the 70 mL bowl.
Fluid Sensors (See Figure 2-6)
The fluid leak sensors are mounted in the centrifuge well. These sensors stop the
pump and the centrifuge if fluid comes in contact with the fluid sensor surface in
the unlikely event of a bowl leak. One sensor is located on the side of the
centrifuge well at the level of the bowl seal and the other is located below the
bowl optics sensor, near the base of the centrifuge well.
Waste Bag Weigher (See Figure 2-7)
The waste bag weigher checks the weight of the fluid in the waste bag, alerting
the operator when it is almost full and also when it is full. In the Automatic mode,
the message “EMPTY WASTE BAG” is displayed when approximately eight liters
of fluid are in the bag. In both the Automatic or Manual modes, the message
“WASTE BAG FULL” is displayed when approximately nine liters of fluid are in
the bag. In the Manual mode the waste bag weigher can be turned off by pressing
the MODIFY key and going into the setup screen.
Clamped Line Sensor
Figure 2-7: Clamped line sensor
The clamped line sensor monitors pressure levels in the blue and red lines during
EMPTY and RETURN. If the clamp on the bag or reservoir is inadvertently closed,
the clamped line sensor will cause the pump to stop and the following message
will be displayed.
