24. 24 Gas in Error 29-Sept-2009Operation of CSC DCS24  CSCs are designed to run for 24 hours without fresh gas while beam is off.  If gas goes out during the Morning shift or Afternoon shift, wait an hour and then call the CSC Field Manager (165509) if gas is still in error.  If gas goes out during the Owl shift, inform the morning shifters of the problem and have them call (165509) at 8 am if the gas is still in error. Back

25. 25 Cooling in Error 29-Sept-2009Operation of CSC DCS25  Our Cooling is only indicative as to whether it is safe to turn on.  If Cooling is in error while the system is off and wants to be turned on, call the CSC Field Manager (165509) before turning on.  If the Cooling goes into error while CSC system is on, monitor chamber and rack temperatures.  If 36 or more chambers are red (T > 32 °C), turn off entire system and call 165509 We would like to request that an SMS be sent to 165509 in the event of a cooling error. Currently it only sends to A. Lanaro Back
