S.MonteilPS/SPD COMMISSIONING1 OUTLINE 1)Overview of the system. 2)Discriminating errors. 3)Tricks. RUNNING PRS AND SPD – FIRST DRAFT TUTORIAL

S.MonteilPS/SPD COMMISSIONING2 1) RUNNING PRS AND SPD

S.MonteilPS/SPD COMMISSIONING3 1) RUNNING PRS AND SPD To operate PRS and SPD, you need to have: VFE power supply ON : INFDAI project. HV on the tubes ON : PRSHV projects (- see corresponding tutorial). but not only : LV and MV hardware have to be settled up. FE Electronics Crates ON : INFDAI project. Whenever an error occurs at the configuration of FE electronics, it is most likely related to one of the three preceding items. This is the first things to be checked.

S.MonteilPS/SPD COMMISSIONING4 PSFEB project improved with glue resets included. CROC project improved with specs master resets included. SPD CB project improved with checks of registers. Configuration time is an issue on C-side (more than one minute). Bottomline: it’s robust. 1) RUNNING PRS AND SPD

S.MonteilPS/SPD COMMISSIONING5 1) RUNNING PRS AND SPD The hierarchy of the projects: TOP LEVEL : PRS : CONTAINS PRSDAQC AND PRSDAQA.

S.MonteilPS/SPD COMMISSIONING6 1) RUNNING PRS AND SPD The hierarchy of the projects: SECOND LEVEL : PRSDAQX1 : CONTAINS FOUR CRATES PRS_X, PRS_LEDTSB, PRS_TELL1. For the time being, PRS_LEDTSB is configured independently.

S.MonteilPS/SPD COMMISSIONING7 1) RUNNING PRS AND SPD The hierarchy of the projects: THIRD LEVEL 1 : PRS_TELL1 (See Tell1 tutorial). The trick : if a Tell1 board goes into error, RECONFIGURE. If at the fourth reconfiguration, it still fails : CALL the experts.

S.MonteilPS/SPD COMMISSIONING8 1) RUNNING PRS AND SPD The hierarchy of the projects: THIRD LEVEL 1 : PRS_X : Contains 1 CROC, 14 (8) PSFEB, 2 SPDCB.

S.MonteilPS/SPD COMMISSIONING9 2) Discriminating errors The Shift Leader job is to configure all the relevant electronics at the start of the run: SCENARIO 1 : Everything goes fine (shall be the dominant state). SCENARIO 2 : PRS felt in ERROR (shall occur). The first thing to do is to enter the ECS hierarchy and diagnose which element is on ERROR. CASE 1 : ALL 1/ Check the crate power supply (see appendix 0.0). 2/ Check the SpecsMaster. Restart/Reset (see appendix 2). 3/ Call Expert.

S.MonteilPS/SPD COMMISSIONING10 2) Discriminating errors CASE 2 : SPDCB 1/ ERROR : Check the VFE power supply status. 2/ STUCK into CONFIGURING : GO to FAKE_READY and state somewhere that the board is not configured. 3/ Anything else : call the expert. CASE 3 : PSFEB 1/ Check the log of the project (see Appendix 0). 2/ If it is a unique Delay_Chip, you’ll have to change through the Hardware Tool all the bits and then reconfigure from top (see Appendix 2). 3/ If all delay_chips, you have to launch a CAT project (see Appendix 3). 4/ Any other problem requires an expert. CASE 3 : CROC 1/ Check the SpecsMaster: Restart/Reset (see Appendix 1). 2/ If it fails, call the expert.

S.MonteilPS/SPD COMMISSIONING11 3) APPENDIX : The How To tricks Appendix 0.0 : Checking the power supply status. INFDAI project form the Calo PVSS shortcuts. See ECS tutorial. Stuck today. No printscreen. Address: /group/calo/pvss/INFDAI_UI_DEN Suppose it is stuck (as it is right now), you have an alternative solution: Go to /group/calo/spd/snmp And check the html interfaces MonitorPrsxxx.

S.MonteilPS/SPD COMMISSIONING12 3) APPENDIX : The How To tricks Appendix 0 : Checking the Log Viewer Once you have diagnosed where the configuration error occured in the ECS hierarchy, START PVSS on the relevant machine (see Twiki). Start the console ( see ECS tutorial). Start the Log Viewer ( each of the 2 latter operations is single click). Recover the error, reconfigure and get the faulty datapoint.

S.MonteilPS/SPD COMMISSIONING13 3) APPENDIX : The How To tricks Appendix 1 : Reset the SpecsMaster through the SpecClient Shortcut: Select the PC Select the Specs Master of the corresponding crate LHCbTwiki - LHCbCalo - LHCbECS Click on Reset Master (Hard).

S.MonteilPS/SPD COMMISSIONING14 3) APPENDIX : The How To tricks Appendix 2 : Changing one register in the Hw Tool (DelayChip example). 1. Open the HW tool 2. Select PSFEB 3. Goto Hardware 4. Select PSFEBxx 5. Select DelayChip_xx 6. Then View Recipe 7. Change the number: FFFFFF then Reconfigure form main panel. 9. If it fails, call …

S.MonteilPS/SPD COMMISSIONING15 3) APPENDIX : The How To tricks Appendix 3 : Launching a CAT process (DelayChip example). 1. Open a command window 2. Cdir : C:/Applications/CAT_ _CAT/CATLPC 3. Setup_controlroom.bat 4. Launch the CAT for the relevant crate goPRSx.bat 5. In the application window, select the process Shake FEB delays. 6. Execute it with the upper button. 7. Reconfigure form main panel.
