Changing flow rate:
To change flow rates, simply go to the main screen select P-Flow SP. Enter the new flow rate on
the pup-up menu. Press Yes to accept current PV and PRV values or press Default to accept
default PV and PRV values. Default is recommended when entering new flow rates. Follow
similar procedures to change E-Flow SP. It is recommended to STOP the controller prior to
change of flow rate. Following the change, re-START the controller. It will start with the
diaphragm in the fully exhausted position.
Filtrate or Harvest:
Start the Filtrate (or Harvest) pump only after XCell™ ATF System flow has stabilized. Stop the
Filtrate / Harvest pump when stopping the XCell™ ATF System flow; accordingly, the C410v4B
controller provides relay outputs on the E-BOX for activating or deactivating a filtrate / harvest
pump.
