CO2 progress and issues on the control system From Łukasz CO2 PLC PVSS UNICOS project creation status: 1 – Excel specification preparation √2 – PLC hardware configuration √3 – PLC & PVSS instance generation √4 – Process logic program preparation √ 5 – Specific functions preparation√ 6 – Code compilation √7 – Loading to PLC √ 8 – PVSS Data Server configuration √ 9 – PVSS panels creation √10 – Commissioning & operation – began – all sensors values are archived Specification SCADA server InstanceGenerator SIEMENS PLC Logic Generator Jan Godlewski PH-DT-PO
CO2 progress and issues on the control system Signal-electrical installation: 1 – Control rack completed √ 2 – Plant frame equipped with cable trays √ 2 – Signals cables in place and 90% connected √3 – Power cables in place and connected √4 – All sensors ,actuators and cables labeled √ 5– All PT100 connected with additional connector to ensure in case of failure fast sensor replacement √ From Łukasz Jan Godlewski PH-DT-PO
Missing parts and things to do • Missing parts • Accumulator from NIKHEF • Hans Postema in contact with NIKHEF • We are requesting it for mid of June • Expansion valve for accumulator cooling • Should come these days • Some sensors • Valves extensions for cold running • Still to do • Installing and connecting accumulator • Installing valves extension • Insulation • Final commissioning of control system Jan Godlewski PH-DT-PO
Summary • CO2 test stand • Test stand ready for “warm” operation • We are waiting for accumulator from NIKHEF • First thing to test will be ATLAS Pixel stave (first half of June) Jan Godlewski PH-DT-PO
