1 User guide for Muon shifter part 2 : control of LV, HV, TELL1 Preliminary version 9-July-08 (to be checked by Michela) I have simply put together the instructions (written by Michela Lenzi) in the Muon Twiki page : ssioningHrdw ssioningHrdw to have everything in ppt format

2 LV control For any problem: contact M. Lenzi/G.Passaleva To control LV you should: Log on into lbts.cern.ch PC (online interface to the rest of the world) From lbts you make a remote desktop connection to computer UI01 On UI01 you should look into 'MyComputer' going trough G: -> online -> ecs -> muon -> Shortcuts Then you click on the shortcut of the pvss project you need (LV side A or C, depending on what you want to do).

3 LV control PVSS project Developer: M. Lenzi To start/stop pvss project please read the instructions at The PVSS project has its FSM and to control anything you need, first of all, to 'take' privileges.... Then you can navigate the panels trough the Quadrant and stations that you need to work on.

4 Maraton issues Experts: M. Lenzi, P. Ciambrone. For any hardware problem please contact P.Ciambrone. Sometimes the Maraton goes into a funny state: it shows errors that are unlikely to be real hardware failures. In those cases you should carefully check : - that the OPC server is running correctly and the RCM is talking communicating correctly - that the communication btw the RCM and the Maraton is correct OPC server restart can be done only with administrator privileges (ask M. Lenzi) To exit from real funny situation the following chain of actions has proved to help: turn off PVSS and OPC server Reboot RCM crate Restart PVSS and OPC server Poer cycle the Maraton After each step you need to check that the communication is going as expected. Latest maraton known problem: last november! Since then everything is running smoothly.

5 How to start/stop pvss projects for HV, LV and Tell1 All the projects have been configured as services, so that they will start automatically (included the FSM) after a reboot of the machine. If you want to start/stop manually: (N.B. all projects run as muon_oper and all the muon group has the permissions to start/stop projects, so you can do from your account, you don't need to use my account) for windows projects (MULVA01, MULVC01, MUHVA02, MUHVC02): 1) login using your account on the machine where the project runs 2) open the service+ tool panel 3) - to start the project: start the service ProjectName (e.g. MUHVA02) - to stop the project: start the service ProjectName-Stop (e.g. MUHVA02- Stop). Please, do not stop the project by stopping the service ProjectName (use ProjectName-Stop to stop it cleanly). 4) log off from the machine and take the control of the project using the shortcut to the project from the machine UI01

6 New instructions to start/stop pvss projects for HV, LV and Tell1 for linux projects (MUDAQL1): 1) login using your account on the machine where the project runs 2) to start the project: type the command sudo /sbin/service pvss_mp start - to stop the project: type the command sudo /sbin/service pvss_mp stop 3) log off from the machine and take the control of the project using the shortcut to the project from the machine UI01 for linux HV PNPI projects (MUHVA01, MUHVC01): a special script has to be used to start/stop the PNPI system, included the hvcard driver and Dim server: 1) login using your account on the machine where the project runs and go in the directory /localhost/pvss 2) to start: execute the script./startPNPI to start the hostcard driver, the dim server and the pvss project or execute the script./startDimPVSS to start only dim server and pvss project. - wait and be patience for a few minutes until you get the message "PNPI system initialization finished" - to stop: execute the script./stopPNPI to stop the hostcard driver, the dim server and the pvss project or execute the script./stopDimPVSS to stop only dim server and pvss project. 3) log off from the machine and take the control of the project from UI01 see and for more detailed instructions.

8 UF/PNPI system operation (M. Lenzi) Four recipes have been stored in the Configuration DB and can be applied sending FSM commands: Go_STANDBY1, Go_STANDBY2, Go_READY, Reset: COMMANDV0Set (RDB) (V) V0Set (Master) (V) Go_STANDBY Go_STANDBY Go_READY Reset00 Ramp Up = 3V/s Ramp Dw = 50V/s Trip time = 1s I0Set: - 200uA (master channels) - 1uA (gap channels) - 3uA (4 gaps channels) Contact me if you want to change these settings!

9 1.Login on UI01 (windows) machine in the LHCb online cluster 2.Go to folder G:\online\ecs\Shortcuts\MUON and click on MUHVC01_UI_FSM The panel in Figure will appear 3.Right-click on MUONPC_HV First instructions to start learning how to operate the UF/PNPI system using PVSS project:

10 Note: red locks mean that somebody else has the control: you can monitor the status but you cannot operate the system Please remember to release the control (ReleaseAll) when you don’t need it anymore 4. Take the control of the project

11 5. Switch on masters with the command Go_STANDBY1 For experts only (please contact me before using)

12 Master operational panel:

13 6. wait until the state of PNPI_MASTERS is STANDBY1 7. send the command Go_STANDBY1 to one quadrant, e.g. Q3

14 Quadrant monitoring panel:

15 Station monitoring panel:

16 8. Wait until the state of Quadrant Q3 is STANDBY1

17 9. Send the command Go_STANDBY1 to the next quadrant, e.g. Q4:

Wait until Q4 is in state STANDBY1 11. Repeat the procedure from step 5 to step 10 for the commands Go_STANDBY2 and then Go_READY

19 Region monitoring panel:

20 Chamber monitoring panel: Vmon and IMon are stored in PVSS archive DB

21 General remarks: - Operate the system from UI01 machine: do not login on muhvc01 machine, do not start pvss, dim server, dns, etc. from your account - Remember to release the control of the project before leaving - Be patient: when you send a command, wait until the command has been executed (and the FSM states have changed accordingly) before sending further commands - If you want to do more sophisticated operations, i.e. change recipe settings, change archive DB settings, run auto-detection procedure for masters, save/load master Id from Configuration DB, etc. please ask me: do not try to do it by yourself before learning how to do it. - If you see some problems please contact me so that I can investigate immediately (it is hard to reproduce and understand a problem the day after..)

22 Switch On/Off all boards - If you are not able to switch on channels, most of the times is because the boards are off (solution: click on “Switch on all modules”)

23 HV control (CAEN) CAEN & PNPI controls will be unified in a single control structure. Michela is working on this and will update the instruction file when this integration will be completed.
