Messages displayed Explanation
Priming
The first series of cycles performed to prime the ATF
pump and remove most or all of the air in the XCell
ATF® Device and tubing.
Zeroing FT
The controller stops the ATF pump and waits until there
is no flow in the A2B line and then zeros the flow
sensor.
N/A
Waiting
Shown rarely in dual mode during the initialization
stage, for example, if the system is waiting for liquid
flow to stop in the second ATF before zeroing the
sensors.
Detecting MinPress
The controller runs an automated algorithm to
determine the minimum driving pressure required to
move the diaphragm.
Stopped
A Stop button has been pressed on the HMI.
Paused
A blue Pause button has been pressed, either on the
HMI or on the side of the controller.
Pressurizing
The controller is performing the P-stroke, i.e.
pressurizing the diaphragm and moving it up displacing
liquid into the vessel.
Exhausting
The controller is performing the E-stroke, i.e.
exhausting the diaphragm and moving it down
displacing liquid into the ATF pump.

XCell ATF®
D
and
D-P
controller models can run two XCell ATF® Devices at the same time. If the
devices are same size and connected to a single bioreactor, they may be run in one of three
synchonized modes (
). To switch from the single to dual mode, open the settings > ATF
configuration sub-menu (
) and select an XCell ATF® Device for the B channel then
bioreactor configuration and select a configuration (
) the ATF Flow Pop-Up and select the
Note:
Modes can be switched even while the devices are running; it takes one to two full cycles
before the new mode goes into full effect.
