1. IBL CO 2 cooling control system development status 19.03.2013 Lukasz Zwalinski – PH/DT/DI Maciej Ostrega – PH/DT/DI Florian Corbaz – EN/CV/DC

2. Presentation overview: Hardware A) control cabinets B) accumulator local box System architecture Electrical connections Cabling Control system development status: Fixed control rack position Prepared first version of control documents: -ATLAS IBL CO2 Cooling Station Functional Analysis For Continuous Process Control (CPC) EDMS 12334621233462 -Specification of control interface between cooling control system and ATLAS Detector Control System EDMS 12334641233464 IBL CO2 cooling control system development

3. Status: Control/electrical rack layout design completed Electrical schematics nearly completed by Florian 95% of control hardware components ordered and delivered Assembly by EN/CV already started Control cabinets Lukasz Zwalinski IBL 18 th March 2013 IBL A IBL B Layout prepared by S.Berry

4. Intermediate control box for maintenance operation Lukasz Zwalinski IBL 18 th March 2013 What does it serves for? local maintenance manipulation independent from control racks! Status: Rack layout design completed Electrical schematics completed by Maciej Assembly in PH/DT started Still minor components to be ordered Front panel to be graved with P&ID by NIKHEF Characteristics -Individual 24V DC hot swappable power supplies -Separate 230V power -Local valve position indicators (LED + signal send to both PLCs) -Local valve manipulation panel -Local vacuum pressure indicator -Local vacuum pump start/stop with protection -Emergency switch

5. System architecture OWS Premium CPU IBL plant B Local MODBUS TCP/IP Pneumatic lines FESTO WAGO I/Os EN/CV Terminal server Detector Control System ATLAS DSS Local Touch Screen Hardware signals DIP Central Control Room IBL plant A Local MODBUS TCP/IP Pneumatic lines FESTO WAGO I/Os Local Touch Screen Critical data tunnel from PLC to DCS Premium CPU Lukasz Zwalinski IBL 18 th March 2013

6. System architecture Lukasz Zwalinski IBL 18 th March 2013 System architecture conclusions: 1.PVSS server location agreed with ATLAS ID and DCS to be in CCC 2.Server is already installed in CCC 3.The data base for long data storage has to be selected! (ATLAS vs LHC TIMBER) 4.PLC will send ~20 most critical signals with direct MODBUS protocol to the DCS 5.Rest of the signals will be send to DCS using the DIP protocol 6.The UNICOS library extended for WAGO Ethernet IP modules 7.There will be common accesses from Detector Cooling CCM IBL A IBL B

7. Status: Architecture, power requirements and electrical hardware discussed with Wieslaw Iwanski & EN/EL James Devine EN/EL with an agreement of the EN/CV will provide us ASAP Information about the staring point Florian will make TRACIEL calculations to verify protection sizing and guarantee correct selectivity Wieslaw agreed to supply all IBL control system from UPS UPS feeder will be decided depending on whether or not IBL system shall be – and if so in which part – interlocked with DSS ??? Electricity, system powering – ATLAS UPS Lukasz Zwalinski IBL 18 th March 2013

8. Status: Cable schedule with patching details completed (cable size, pinouts, wire colours NIKHEF is informed and terminals are send to them with patching details Signal cables installation between USA15 and UX15 already started by S. Malyukov Power cable for dummy load still need to be pulled once the TRACIEL calculations are completed Thermocouple type K halogen free cable for dummy load protection has to be purchased and pulled DSS and Bake-out cables has to be pulled whenever we know the destination racks Input file to print out ATLAS DB cable labels ready for Irina Malyukova The communication with Bake-out system has to be defined (we send 24V or Bake-out system sends 24V?)
