System Functionality
8.2.7 Ctrl Mode
Ctrl Mode is used when no Aux Pump 1 is available and additional buffer or sample is pulled into the
sealed process reservoir by vacuum. Please refer to section 8.2.2 how to setup the reservoir to pull
the vacuum. This is called "Control Mode" because the user can tell the KF Comm software when the
concentration ends and diafiltration begins instead of being done in auto mode. Please see section
below for further explanation.
In Control Mode, the user can manually tell the pump when their flowpath is routed
to run in a Concentration or Diafiltration configuration. The Data Collection and
calculations on KF Comm will reflect which of the two functions is running until
either the “Permeate Weight Stop” set-point is reached or the user presses “Stop”
on the Pump or Pump Control. Control Mode can only be accessed properly using KF
Comm on a computer.
