Equipment quantities.

• Racks in Barracks
• 6 switchboards of 23 drawers (138 racks).
• Racks in Detector side
• 4 switchboards of 23 drawers (92 racks).
• General
• General Services switchboards (EBD) and UPS
  Distribution switchboards (EOD) not considered
  here.

4
Equipment location

• Bad Side
• Radiation level consideration
• Inaccessibility during operation
• Good Side
• No radiation constraint
• Accessible area
• LHCb validates Switchboards and PLC in Good Side
• PLC closer to switchboards to reduce cabling cost
• DIRIS measurement modules can be in switchboards

Monitoring

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

8
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
