1.2 XCell™ ATF System Control Scope and Objectives
The C410 v4 Controller provides the process control functionality of the stainless steel
XCell™ ATF 4 System, XCell™ ATF 6 System, XCell™ ATF 10 System and the XCell™ ATF 6
and 10 Single-use devices. The XCell™ ATF C410v4B controller is designed to:
1. Control ATF flow rates in both pressure and exhaust cycles
2. Provide a user interface capability for XCell™ ATF System control and monitoring
3. Set-up and select operational parameters
4. Display real-time process data and Alarms for error conditions
5. Provide “Batch control” and user hierarchy
6. Have PLC software upgrades in the field by replacing memory modules
7. Have 3 major enclosures, an Electronics Box (E-Box) a Pneumatics Box (P-Box) and a
Power Box
8. Allow the E-Box to operate an XCell™ ATF 4, 6 and 10 systems and XCell™ ATF Single-use
6 and 10 devices using custom software
9. Allow the P-Box hardware and process parameters to be specific to the size of the
particular XCell™ ATF System being controlled.
Control principles are detailed in Section 6.
