Vacuum (M. Dommach):

• Systematic tests of ion pumps in XTD9 almost finished - ongoing
• Interface with MPS has to be tested
• Problem with the fast valve in XTD2 and 9 - it is possible to close it remotely but not possible to open it again. Checking of the cabling is ongoing by Vacuum group
• After restart of the vacuum loop many pumps in XTD 9 and 2 show an unknown error and some of them are not readble - CAS working on that.

PLC (P. Gessler, T. Freyermuth):

• Implementation of shutters in Karabo ongoing -XS3 shutter in the VAC loop now. XTD9 to do.

Karabo (A. Silenzi):

• GUI stability improved with a temporary solution. This should be enough to guarantee the proper functioning of images acquisition.
• Update of devices list ongoing
• Library for motors (base device), elmo and technosoft, being worked out.

Plans for today:

• XGM work on gas injection
• Bring back Karabo and clear XGM error codes
• Perform systematic test of DPS in XTD9

Other topics:

• No 09:30 meeting tomorrow - next meeting will be on Wednesday

WP74   OCD  for the  weekend 6.5.-7.5.2017:

Saturday: Jan, jan.gruenert@xfel.eu, 9-5777

Sunday: Theo, theophilos.maltezopoulos@xfel.eu, 9-6792

AE on call service:

    Contact person:

        9 - 5627

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.

The current slow response times in the karabo GUI are the following (some measured times for reference):

- opening a project from the project manager : 45sec (just loading, not yet touching any device or scene)
- opening a scene and receiving the status for all devices e.g. XGM@XTD2 : between 90 and 120 sec
- beyond that, it's never clear if the displayed gauge values are true/actual and must be separately read.
- reading explicitly a gauge value (with command READ in configurator) gives currently an updated value after about 10 sec (should be almost immediate when requested)
-----> working with this (getting actual work done) is practically almost impossible

- this is using the "new" gui server "sa1-br-sys-con-gui2"
- this is after 19h30 (shouldn't less traffic help the performance ?)

Dear All,

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

See you,

Sandor 

 Hallo allerseits

 Dear all,

during the test run today by our colleagues of WP74, the interlock condition inside the XGM module was met (small volume pressure burst up to 10-2 mbar range). Now we can see also the expected cut-off event of the gas injection (see attached pictured). It seems that the reason why there was any feedback from the respective shut-off valve was the solenoid actuator on the respective shut-off valve was set in manual mode.

This means that XTD9 Interlock for the whole gas section has been up and running as expected the whole time.

Best Regards.

 5th. On Thursday, there will be operation till 14:00, after 14:00 the machine will be 
 switched to standby. All the work planned will shift accordingly by one day. No ZZ before 
 Thursday 14:00. 
 
The machine will be shut down Friday moring 7:00.

or

 Dear all,

it seems that this morning was somehow a misunderstanding. The XTD9 Gas Section Interlock test was succesfully finished the last 26th of April (see e-log message nr. 179).

There´s no further activity planned for this system.

Regards.

Tunnel Status: XTD2/4/10 closed. XTD9 open. Controlled Access to 2/4/10 possible upon request

Vacuum (M. Dommach):

• Systematic tests of ion pumps in XTD9 concluded
• Tests of DPS in XTD9 should happen today with R. Villanueva
• Systematic tests of all interlock conditions in XTD9 should happen tomorrow

PBLMs (H. Sinn, P. Gessler):

• Debugging session for the ELMO controller was successful. The problem was traced to details in the parameter settings
• Proper setting of parameters is tricky and requires care and expert knowledge.
• Proper parameters now need to be programmed into the firmware. Manual setting is also possible but not favored.
• AE will set this up and deploy next week in order to maximise optimal use of resources (This week only one expert, TF, is here)

Imagers (A. Koch):

• Imagers in XTD2 and XTD9 are ready for beam
• It is important that images can be stored. This is not yet the case and will be required latest when PBS commissioning starts
• AK will be away from tomorrow until next Thursday

XGM (J. Grünert):

• Late yesterday, Karabo went into error triggering the interlock on the Vatterfly valves on both XGMs. Pressure is still low but slowly rising
• If the condition cannot be resolved remotely a local intervention is necessary. This can possibly wait until the scheduled interrupt tomorrow
• Today tests should occur with the DESY experts for gas injection
• Tests are currently hindered by the Karabo problem. AS suspects that this may have to do with the redeployment of Karabo yesterday. He is now working with high pressure on solving the problem

FXE (A. Galler):

• Currently commissioning loop 1. There is still a problem reading out encoders. It appears that this is a firmware issue. TF is working on this.

SPB (B Weinhausen):

• Fixes were deployed in the firmware for the Reinshaw encoder problem (16/32 bit issue). Still one encoder is in error. TF points out that this is a different problem. He will investigate

PLC (P. Gessler, T. Freyermuth):

• CRL in XTD2 was integrated into the PLC motion loop yesterday during the access.
• Meeting today with DESY experts to finalise the EPS logic
• Focus this week on SPB and AGIPD

Karabo (A. Silenzi):

• Karabo (Components Beckhoff-Device and Beckhoff-Com) were re-deployed yesterday.
• This maybe the origin of the problems observed in the evening 

Plans for today:

• XGM work on gas injection
• Bring back Karabo and clear XGM error codes
• Perform systematic test of DPS in XTD9

Other topics:

• No 09:30 meeting tomorrow due to access. 
• Request should be made to break the interlock in XTD10 on maintenance days in order to allow continuation of installation work

Wajid and Leonce from CAS have managed to get us the karabo controls back.
We have now put the XGM@XTD9 back into normal vacuum operation, and opened finally the vatterfly valves, this one is ok, and we checked also the entire XTD9 gas section to be ok.

However, in XGM@XTD2, both XGM turbo pumps are still in ERROR and we cannot get them out - it is an error on the PLC level ? It's something we have not seen before.
The vacuum is at a controlled level of 5E-7mbar thanks to interlock-closed vatterflys.

Request to AE: tomorrow morning, we must remotely get the two turbos out of error (PLC client ?), otherwise we have to request a ZZ access to the tunnel XTD2 for local intervention on the turbo pump controllers.

Request to the AE+CAS group leaders: apparently we need to organize OCD also during nights on weekdays.

All devices went into unknown state in the karabo XGM scenes in XTD2 and XTD9 at 19h52.

Pressures INCREASE since then (as measured/shown in DOOCS):

XTD2:  2,5E-7mbar and rising

XTD9:  7,7E-7mbar and rising

Please respond now !! We are still in but want to go home !

 This Thursday the XTDs will be accessible with ZZ procedure. Access can be requested via T. Haas. 

XTD2: All gate valves are now OK (not interlocked) after re-instantiating and re-setting the XGM_DP_OK. 

The interlock errors of some valves in XTD9 are shown in the screen shots below (Janni and Valerii starting now in XTD9 to debug some more controllers)

Hi all,

due to ongoing tests with the PBLM motor drivers I have to set the Elmo drivers in PreOp mode.

That should not affect any other terminal in the loop.

Cheers,

    Tobias

Not really official, but in emergency case you can call 96993 for vacuum group. Next week Martin is back and I think we will have official on call service.

Have a nice weekend with hopefully no problems :-)
