3 29-Sept-2009Operation of CSC DCS3  If a HV Primary Supply is in error, this is what the system will look like.  Call the field manager at  Any run in progress will continue but there will be no data from these chambers

4 Low Voltage PrimaryLost 29-Sept-2009Operation of CSC DCS4  When a Peripheral Crate Loses LV, check the Low Voltage Primaries (Labeled Maratons)  If a Maraton goes into error, double click the Maraton in error and then in the top drop- down menu select “Off”  Call the Field Manager (165509) after turning off the Maraton  This alarm will probably stop any run with a FED ERROR

5 Maraton LV  This panel shows the status for each of the Maraton LV supplies  Each Maraton supplies LV to either Two Trigger Sectors, TS, of chambers (2x9) plus a pcrate (VME)  4x ~8.0V  1x ~5.5V + 1x ~6.5V Three pcrates (VME) (3TS)  Shown!  3x ~5.5V & 3x ~7.0V  note the voltages and currents for each output channel

23 3 rd Priority  CSC_GAS  CSC_COOLONG

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 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 We would like to request that an SMS be sent to in the event of a cooling error. Currently it only sends to A. Lanaro Back

26 Standby

27 29-Sept-2009Operation of CSC DCS27 Standby State  Standby indicates that the high voltage has been lowered below data taking levels  This is currently also our Safe state  Here only one chamber is shown in standby state, standby will mostly be for all chambers or none Back

28 CommunicationLost 29-Sept-2009Operation of CSC DCS28  When a chamber has a question mark on it, that means it has lost communication with DCS  Mousing over will reveal a No Communication message  If a chamber is out of communication for over an hour, call the CSC Expert (161972) Back

39 Value Monitor  There are 4 mode options for the value monitor display Max Temperature Average Temperature Max HV Average HV  Max Maximum value over the last N? reads  Average Average value over the last N? reads

40 29-Sept-2009Operation of CSC DCS40 Temp/HV Monitor  There are 4 mode options for the value monitor display Max Temperature Average Temperature Max HV Average HV  In continuous running mode keep monitor on Average Temperature  If 36 or more chambers are red (T > 32 °C), turn off entire system and call Field Manager (165509)

41 Value Monitor  The Value Monitor shows the values in color for all chambers  Moving the cursor over a chamber brings up the summary panel for that chamber

42  This panel operates exactly as the ‘old’ version  Note that the panel is shown as locked When this happens follow the procedures to get control!  It is opened by double clicking on the Sub-Systems top button ‘Old’ Top Panel

43 How to change HV value for ME1/1  On Main DCS GUI double click CSC_HV. A smaller icon appears  In this icon change the value (3000→2900) in ME 1/1 HV (Dubna HV) and push “Enter” on the keyboard.  The color of the ME1/1 CSCs will change to blue like it is “OFF”.  1.  2.  One can see the real values moving cursor to the desirable chamber.
