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.

Main DCS Tasks
1. What to do when a DCS alarm occur during the Shift (Concerned Screen : DCS Alarm Panel )
3. What to do when a DSS alarm occur during the Shift (Concerned Screen : DSS Alarm Panels)
4. Monitoring Operation: Services (Racks and Cooling)
5. Underground Cavern Access Management6. DCS Elog : (When and How use it)

DCS Alarm Screen
This screen should be : Checked regularly Empty
Each time an important problem occurs (subdetectors, services, etc…) an alarm (together with an audible alert) should appear on this screen

DCS Alarm Screen
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
On the first line of the page you can see which subdetector is affected by the problem : the alarm will continue blinking until handled by the DCS shifter
Below you find a row where there are several information regarding the alarm : select and right click on it and a pop up window will appear

Blinking values
• If a value is blinking:
you should verify at http://dipg.cern.ch/dipg if there are invalid CMS cooling values. In case the bullet corresponding to CMS Cooling is red, it is very likely to be a problem on the CCC side.
You should call the CCC (72201) to inform them there is a problem with their publications and point to them what you see from the link above.
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, so you should wait about 10 minutes to make sure it is updating, before reporting the problem.

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.
Right-click on the alarm and select ‘Show’ to obtain more information. If the alarm’s “Triggered” state is red, it cannot be acknowledged.
To acknowledge an alarm:
1. click on the ALARM column, on the DSS ALARMS list;
2. Then click on the ACTIONS column of the DSS ACTIONS list.
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!
DSS Alive. Should blink.
If there is a DSS Alarm with Siren and light, the DCS shifter should
immediately call the Technical coordination number 165000

DSS :Detector Safety System
In case of alarms: read the alarm description and contact the
responsible person (e.g. Magnet, subdetectors, etc.);
In case the alarm description is not clear: during working hours: call DSS expert,
Alain Meynet: 163146; out of working hours: call Christoph
Schaefer: 160202 or Wolfram Zeuner: 162541 and at last 165000 (in case the other numbers failed).
Check the DSS display is Alive: These buttons should blink. If not, restart
the panel (instructions in the DSS binder). If restart does not work, call : 162082

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 cDCS twiki:https://twiki.cern.ch/twiki/pub/CMS/OnlineWBCentralDCSInstructions/DCScavernAccess1.3.pdf

10. Select the dosimeter number in the ‘Operational Dosimeter’ field;
11. Read the initial dose from the dosimeter and fill it in the appropriate field of the Shift Operation page;
12. Click ‘Ok’ to grant access to the person;
13. By the return of the dosimeter, fill in the final dose and click ‘Ok’;
14. Turn the dosimeter OFF (simply push the black button on top of the dosimeter, the word “CHANGE” will appear, keep on holding the black button until the word “GO OFF” shows up. Then immediately release the black button. If one waits for too long to release the black button, the dosimeter will not switch off).
