    Overview The High Pressure CO2 Controller I/O The High Pressure CO2 controller (P/N 818-9010) application is a standalone controller that operates the Points High Pressure Valve (HPV) and the Bypass Gas Valve (BGV) in a Booster Transcritical CO2 system. The board has 6 analog inputs and 11 digital in-...

  • Page 8: Independent System Control

    Independent System Control The High Pressure CO2 controller can control the HPV and BGV in a refrigeration Booster Transcritical CO2 System. However, the High Pressure CO2 con- troller is designed to interface with an E2. Network- ing the High Pressure CO2 controller to a central controller also allows you to view status on E2 and UltraSite32 Site Manager status screens, report alarms, and log point values.

To ensure there is a smooth transition between the subcrit- ical PID and the Transcritical PID, there is a linear-ratio transition algorithm between the two PID's output. This linear-ratio algorithm transition will keep the valve open and allow the Transcritical PID to ramp up and take over.
