Radiation and Access Constraints

• ALICE
• UX25
• Radiation level consideration
• Inaccessibility during operation
• PX24
• No radiation constraint
• Accessible area
• ALICE validate PLC in UX25
• PLC closer to switchboards to reduce cabling cost
• Measurement modules in switchboards

9
Monitoring goals

• Monitoring of switchboards and drawers.
• Remote control of drawers.
• States and measurements integrated to ENS.
• Synoptic.
• Fault on electrical trips.
• Alarms on measurements levels.
• Monitoring and Control available to Experiment
  SCADA.

10
Available Signals

• Switchboards
• States
• Input breaker (Opened and Closed)
• 48VDC auxiliary (Missing)
• Measures
• Bus Bars voltages (230V and 37.07VAC nominal)
• Input currents (Ir, Is, It, In CT 1A and 7.07VAC
  nominal)
• Drawers
• States
• Contactor Position (Opened and Closed)
• Breaker Position (Opened) after drawer
  modification.
• Local/Remote switch (LOCAL and Remote)
• Over current trip (SD)
• External Interlock (Activated)
• Measures
• Earth current tore/shunt (7.5A, 7.70VAC nominal)
• Controls
• Contactor Close, Open, Reset external interlock

Conclusions

• Switchboards impose cable/connector type
• Distributed architecture to reduce cabling costs
• Best compromise is SCHNEIDER PREMIUM PLC for
  digital I/O with SOCOMEC DIRIS Ap for measures
• Cabling and system cost related to relation
  rack/drawer
• Change relation gt reduce cost.
