Error Messages - Thermo Scientific Gibco CTS Rotea User Manual

Note:
· The valve volumes are not the same as the volume that has entered or left a bag. In the example
shown, the input bag (cells in culture) is a dual port bag connected to both valve D and G. To
calculate the volume change in or out of the input bag, add the valve volumes for valves D and G e.g.
- 54.6 + 24.9 = - 29.7mL (out of the input bag)
· The valve volume is the volume displaced by the pump and hence does not account for volume
retained in the Single-Use Kit during priming. For example, the net volume for valve A would over-
estimate the volume that has been delivered to the waste bag by the volume of the CFC Chamber
plus the kit tubing.
Note: The Pressor Sensors, P1 and P2, are at a low negative pressure meaning there is a slight
vacuum in the system. These will fluctuate during processing depending on the flow rate and pump
direction. A rapidly increasing Pressure Sensor value would indicate a flow restriction or blockage.
