The vacuum loop is up and running again, with the version 1.11.4.

Denis Finze will connect the shutter signals of the XS3 shutter to the vacuum loop in rack 1.7.

From now on the PLC OCD contact person will have always the phone number:

  9 8040

 Dear all,

The OCD number for tonight (15/05) for the CAS group is 98053.

thanks

 CAS on call service for the night 98057

In case of any problems, please, call the CAS personnel on 9-6443, 9-5630, or 9-6840.

Have a nice week-end, Sandor

Dear All,

During the afternoon CAS has a group activity. Any support can be requested via my phone number: 9-6776.

See you,

Sandor 

just for reference ... here are pictures and schematics of the racks which are involved in the current commissioning.

please find the new (extended) components list under the old link given in the minutes http://tinyurl.com/zn7otsa ,

and check whether all components are included and charakterized by the correct data.

The VCTF-components-list  has been updated. Labels on components, as far as visible, are in accordance with names in list.

... please, check for consistency, when naming and labeling XGM components!

Table updated with status of SPB/SFX devices at end of XTD9 in preparation for SASE1 readiness meeting on 03.02.17

 The interlock definition for complete isolation of the whole section based on high pressure signal has been successfully tested. 

DPS (Upstream and Downstream) are now fully "controlled" by Karabo.

XGM has been reported by J. Grünert that it will be re-integrated during the evening.

Still some problems to call the remote operation of the turbopumps from Karabo, but it doesn´t compromise any of the interlock definitions (only is troublesome if the one needs to work with the pump, for instance after the interlock has been triggered).

 The Fast Valve test has been positively tested. 

It has been consider that the signal on the EPS to open again, should be also available in the vacuum loop. Still this need to be further discussed.

 The Interlock conditions for these two components has been positively tested but not exhaustively done:

The triggering of both via the actuation on the Fast Valve----------------->DONE and OK

Their triggering via HV down of each of the 6 ion pumps------------------>Partially DONE and OK: Partially means that only one of the pumps randomly chosen has been deactivated. The agreement is that the other remaining 5 can be done later, also from the office since the correspondence between the devices and the physical components has been confirmed. 

Also, the individual actuation of both, Beam Stopper and V0 valve has been proof showing a consistent behaviour regarding the interlock definition.

Finally the XFEL Vacuum OK signal is available but AE is currently improving it. By the moment is not automatically sent to DESY, but instead it needs to be activated manually. According to AE feedback this should be corrected in the following days.

 Due to problems and lack of support of CAS for accessing the devices in XTD9 tunnel through KARABO we couldn´t run the test. The system has been returned to manual operation and will remain like that until next notice.

As soon we received the request we worked on that one.  After analysing the issue proper response was sent.

​​​​​Hi Rahul,

we checked all the devices that are in error. The issue is realted with hardware.

Error description is mentioned below:

0x1001 FlagCtrl Error flag from controller

Regards,

Wajid Ehsan 

Here is the list of devices that are in error:
 

SA1_XTD9_VAC/VALVE/V11090A  Error 3 -> valve stayed between open and closed for too long time (3s set on the valve) (the reset command is sent to the PLC and it cannot clear the error)
SA1_XTD9_VAC/VALVE/V11100A  Error 3 -> valve stayed between open and closed for too long time (3s set on the valve)
SA1_XTD9_VAC/VALVE/V11110A  Error 3 -> valve stayed between open and closed for too long time (3s set on the valve)
SA1_XTD9_VAC/TPUMP/P11220T Error 0x1001 -> err_FlagCtrl -> Error flag from controller (need manual reset on the controller) after reset error is now cleared.
SA1_XTD9_VAC/TPUMP/P11280T Error 0x1001 -> err_FlagCtrl -> Error flag from controller (need manual reset on the controller) after reset error is now cleared.
SA1_XTD9_VAC/VALVE/V11210G Error 0x10001 ->  _err_InterlockDevNotFound  -> Interlock device not found. (the valves depends from a SA1_XTD9_VAC/SWITCH/DP_XGM_DP_ERROR which does not exist. a SA1_XTD9_VAC/SWITCH/DP_XGM_DP_OK is present in the list though, likely a PLC configuration error).
SA1_XTD9_VAC/VALVE/V11220G Error 0x10001 -> _err_InterlockDevNotFound -> Interlock device not found.
 

For the last 2 errors, which are the only one that have a clear PLC problem, I created a bug report in the redmine project of AE.

 After some minor issues, the first test has been done today and the interlock wasn´t triggered despite the conditions were met (also visible in Karabo).

This requires intervention and revision from AE

The next try-out should be done as soon as possible during this week.

Regards.

Raúl, Benoit and Valerii
