7.8.1 Changing ATF Flow set points
ATF Flow Set Points (SP) can be changed at any time, including while the XCell ATF® Device is
running. Pressing the white box of the ATF Flow Rate SP (Figure 17
) opens a dialog box, prompting
for the new set point. If the entered value lies within the allowable range, the new value is
immediately implemented. The theoretical Shear Rate SP is also calculated and displayed below the
ATF Flow Rate SP.
If you are unsure of what Set Point is right for your process, contact a local FAS to discuss the impact
of changing the ATF Flow rate for your process.

up window, and then press Start
Pause an
XCell ATF® Device

the hardware match the functionality of those on the software.
A Pause is typically used mid-run, for instance to change out an XCell ATF®
Device, or to adjust something momentarily before continuing as before. If you
plan to stop then restart the XCell ATF® Device within the same process, the
Pause button should be used instead of STOP. Upon pressing Start again, the
controller will resume using the settings and valve positions at the time the
process was paused.
Once device is paused, All Pause button becomes colorless and cannot be
pressed. Upon re-start, the controller starts without utilizing previous settings.

A Stop is recommended to be used only at the end of a run.
