DCS and DSSCuvée 2015 – RUN2

Xavier Vilasís-Cardona


DCS vs DSS

• DCS– Detector Control System– NON-RACK POWER SUPPLIES

• Low Voltage LV– VFEs– LED and HV boards

• Medium Voltage MV– AGILENT

– Temperatures (PS and SPD)• DSS

– Detector SAFETY SYSTEM• ‘If I go off, I cut the power’


DCS – How to get there

• From the top detector DEN

Click to go down into the ECAL DCS

Two types of power supplies involved

• LV – Marathon– They are the same type of the DAI Power

Supplies– See Patrick’s talk for details– RCM’s + Power Supplies

• MV – For HV and TFC status bit– Agilents



Where are the AGILENTS ?

Important

THE AGILENTS (MV) SHOULD NOT BE ON

WHEN THE LOW VOLTAGE (LV) IS OFFor in ERROR

In principle, this is protected by hardware and software, and the system logics but just check.

DCS structre PS / SPD


FSM logics protection

• A simple protection system is implemented in the FSM logics for some subsystems

• LV and MV switch on and off in the correct order.

• SPD VFE power on and off is also protected by FSM logics

• On PS and SPD when temperatures go to error, VFE power supplies are cut off.

More on Temperatures

• Similar panels exist for SPD temperatures. • See Joan presentation.

• SPD temperatures are the probe for VFE power supply problems.

• If all SPD temperatures from one side are in alarm, probably the VFE maraton is in trouble: call EXPERTs.

• SPD temperatures are read from SPECS– Only read if DAQ is configured

• PS temperatures are read from CAN bus– Read independently of DAQ


Monitoring on the Calo Screens

• A summary of the calo DCS information can be displayed on the control room Screens– HV_TOP (Anatoli)– PS Temperatures– SPD Temperatures

• We will also include information from the RACKS – Temperature on the racks– Status of the Power Supplies and Turbines– Rack Monitoring project


CALO HV TOP

• Panel summarises information on HV and DCS

• Prepared by A.Konoplyanikov

DSS

• SAFETY SYSTEM – Runs in an independent system

• PLCs

• DON’T PANIC• DSS essential behaviour

– Some sensor goes wrong • Smoke, temperature, cooling• Ours or others…

– Power is cut somewhere• One side• Somewhere else

DSS and the Calorimeter

• DSS can be triggered in the calorimeter by– Smoke or water in platform racks– Temperature too high in PS or SPD VFE

• Well above DCS alarms– PS and SPD VFE cooling system stop

• If cooling stops, the DSS alarm is not triggered immediately but a warning is sent (SMS)

• DSS cut off takes place 30 minutes later.• Calorimeter Piquet should be warned• The system can be shut down manually by

ECS. 20150421 Calo Piquet Training Session - Xvc 21


What to do if DSS goes off

• Don’t panic• Say your favourite four letter word• A DSS piquet should appear• Find out where the current was cut off and

why.

• If everything is ok for us– Follow the POWER CUT PROCEDURE

Two words on power cuts

• In case of power cut– Wait for control PCs to be ON– If the network is not stable FSMs and project

switching on may be difficult. – Recall projects start automatically– Switch ON DAI first (if not centrally done)– Switch ON DCS from the top of CALO – Remember CALO_UI_fwSystemOverview.sh– Remember

LBECSINFO_UI_FieldbusMonitor.sh



If sth was wrong…

• If DSS alarm was caused by some CALO problem– And it is not a fake alarm

• A sensor went mad
