8. Central DCS General Guideline • As a general guideline all variables controlled and monitored by central DCS should be GREEN • If not green, a corresponding alarm will be raised and will appear in the central DCS Alarm Screen; • Therefore it is very important to monitor the alarm screen during your shift and have prompt action in case of any alarm; • In the next transparencies, the central DCS shifter tasks will be visited one by one, keeping in mind this general guideline.

9. DCS entral Main DCS Tasks • What to do when a DCSalarm occur during the Shift (Concerned Screen : DCS Alarm Panel ) • What to do when a DSS alarm occur during the Shift (Concerned Screen : DSS Alarm Panels) • Monitoring Operation: • Services (Racks and Cooling) • Underground Cavern Access Management • DCS Elog : (When and How use it)

10. DCS Alarm Screen • This screenshouldbe : • Checkedregularly • Empty Each time an important problemoccurs (subdetectors, services, etc…) an alarm (togetherwith an audible alert) shouldappear on thisscreen

11. DCS Alarm Screen On the first line of the page youcanseewhichsubdetectorisaffected by the problem : the alarmwill continue blinkinguntilhandled by the DCS shifter Belowyoufind a rowwherethere are several information regarding the alarm : select and right click on it and a pop up windowwillappear • Read Instructions to correctly handle the alert : • In case you don’t know how to solve it call the responsible • If there is no instruction send an email to us

12. DCS Alarm Screen SUBDETECTORS MAIN LINE: Colors meaning list : LIGHT BLUE : No errors RED: Fatal alert ORANGE: Error YELLOW: Warning GREY: Alert acknowledgeable Time stamp (when shifter has clicked on Alarm Help) Direction box : CAME : The condition which triggered the alarm is still present WENT : The condition which triggered the alarm has disappeared

Follow the instructions Rack Power Status per underground area S1-S4 = Service Cavern X0-X5 = Exp. Cavern Color code: Grey – Not used Green – OK ------------------------ Blue – OFF -> Red – ERROR -> requires intervention! If you click on 1 rack you get details on it

16. Cooling Panel Service Screens (Cooling) TOP PART OF THE SCHEME Color code: Green – OK -------------------------- Yellow – warning Orange – Error Red – FATAL ERROR Blinking Values requires intervention! Outside working hours: TOP PART of the screen: ORANGE, write on DCS e-log, RED - Call CCC 72201 BOTTOM PART of the screen (flow & tank levels) : ORANGE : 17h30/24h00 call 165000 24h00/7h00 ignore, RED, call 165000 During working hours (8h30/17h30) no matter which doubt or change of color: CMS cooling support, 163021 BOTTOM PART OF THE SCHEME Rack circuit leak Warning: 2 l/h > 60 min Alarm: 6 l/h >30 min min or 8 l/h >1 min Copper circuit leak Warning: 1 l/h > 60 min Alarm: 4 l/h >30 min or 8 l/h >1 min Aluminum circuit leak Warning: 1 l/h > 60 min Alarm: 4 l/h >30 min min or 8 l/h >1 min

17. Service Screens (Cooling) • Blinking values • If a value isblinking: • youshouldverifyathttp://dipg.cern.ch/dipg if there are invalid CMS cooling values. In case the bullet corresponding to CMS Coolingisred, itisverylikely to be a problem on the CCC side. • You should call the CCC (72201) to informthemthereis a problemwiththeir publications and point to themwhatyouseefrom the linkabove. • If there are no invalid values in the link above, call the central DCS expert and inform about the problem. • The interface from above is slow, soyoushouldwait about 10 minutes to make sure itisupdating, beforereporting the problem.

18. DSS :Detector Safety System Right-click on the alarm and select ‘Show’ to obtain more information. If the alarm’s “Triggered” state is red, it cannot be acknowledged. Front End warning light : should be always green. If not, call Alain Meynet, between 7:00 and 22:00. If red during the night, call Alain Meynet in following the morning. If there is a DSS Alarm with Siren and light, the DCS shifter should immediately call the Technical coordination number 165000 To acknowledgeanalarm: click on the ALARM column, on the DSS ALARMS list; Then click on the ACTIONS column of the DSS ACTIONS list. DSS Alive. Should blink. User should always be set to ‘user’. If not, click on Logout. The panel will restart automatically. Stop Siren button:stops the siren in the DSS hardware panel when there is an alarm. Only works from the DSS USC55 panel!

19. DSS :Detector Safety System • In case of alarms: • read the alarm description and contact the responsibleperson (e.g. Magnet, subdetectors, etc.); • In case the alarm description is not clear: • duringworkinghours: call DSS expert, Alain Meynet: 163146; • out of workinghours: call Christoph Schaefer: 160202 or Wolfram Zeuner: 162541 and at last 165000 (in case the othernumbersfailed). • Check the DSS display is Alive: • Thesebuttons shouldblink. If not, restart the panel (instructions in the DSS binder). If restart does not work, call : 162082

21. Underground Cavern Access • Every person going underground (Service and Experimental caverns) is required to fill in the paper version of the 'Access to Experimental and Service Caverns' list that can be found in a binder by the Shift Leader's desk; • The central DCS shifter has to check that the person fills this form when he/she goes into the cavern and when he/she returns; • The person has to have a mobile phone; • If after some time the person is not back in the control room, call him/her to check everything is ok. You can find detailed information on underground access in the cDCStwiki: https://twiki.cern.ch/twiki/pub/CMS/OnlineWBCentralDCSInstructions/DCScavernAccess1.3.pdf

23. Underground Cavern Access • Each person that wants to access the experimental cavern has to be properly registered in a WP; • The Access management software Work Packages (WP) is reachable from the CMS Online Page ( clicking on ACT ) or directly from this url : http://cmsonline.cern.ch/portal/page/portal/CMS%20online%20system/ACT

Underground Cavern Access • Once the authorized person has received his dosimeter (s)he can finally access to the cavern, and in the two displays here below the DCS Shifter can check all the cameras pointing at the different doors in the cavern : When the person reach the entrance (21) there are still few steps to be execute … 21

32. Underground Cavern Access • … he needs to pass his badge over the card reader in the yellow underground cabinet (22) : Then on the DCS screen his name will appear in the dedicated window (23 and the DCS Shifter has first to select the line and then click the button “Give the Key” (24) in order to let the drawer in the underground rack opening (25) and delivering the access key to him. The name will appear here …. 23 22 25 24 Once selected the name the button will became clickable
