1. describe how cascade works?
2. describe how to put the secondary and primary into cascade and auto?

cascade: the primary controller is the lIC, level controller on the column overhead receiver. The secondary controller is the FIC, reflux flow controller. The range of the FIC IS 0-50GPM. The FIC is in the cascade to the LIC.
3. Is the LIC direct acting or reverse?
4. Is the FIC direct acting or reverse?
5. If the LIC OP IS 10% what is the SP of the FIC?
6. If the FIC SP IS 40 GPM, what is the OP of the LIC?

Cascade: The primary controller is the TIC, temperature controller on column tray 10. The secondary controller is the FIC net overhead flow controller. the range of the FIC is 0-20 GPM. the FIC is in cascade to the TIC.
7. Is the TIC direct acting or reverse?
8. Is the FIC direct acting or reverse?
9. If the TIC OP is 25%, what is the SP of the FIC?
10. If the FIC SP is 19 GPM, what is the OP of the TIC?
