Central DCS General Guideline
D
C
entral
S
 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.

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 Management
6. 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

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
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

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.

(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:

 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:
