The first EtherCAT coupler in 1.7 VAC was broken and is replaced now. The loop is up and running again.

Cheers,

    Tobias

Dear all,

The Motion loop would be updated now in order to fix names problems with PSLITs motors. In few minutes would be reachable again.

Than you!

Dear all,

The EPS loop is running again with the last modifications concerning devices' names.

Thank you.

XTD Tunnels open until 15:00. Later XTD2 and XTD4 are closed, XTD9/10 remain open

Vacuum Loop:

Status:

• One broken Beckhoff terminal was exchanged before the weekend. This was the first failure of this type in 2 years
• After this the system ran without hickup over the Easter weekend
• The fix applied for ion pumps that avoids triggering an interlock condition when there is a communication failure on the serial output should be also applied now to other vacuum device, e. g. the turbo pumps

EPS Loop:

Status:

• Requires an update to be done asap so that N. Gerassimova can continue tests with the PBLMs afterwards

Motion Loop:

Status:

• Movement of the PBLM motors (ELMO controller) is not satisfactory yet. Motors start and stop but the movement is uneven and stops not always requested
• There is no test set up in the lab. So tests have to be done in the tunnels (XTD9)

PBLMs:

• All systems in XTD2 were tested and cameras calibrated including some at the beginning of XTD9
• Work continues on remaining systems in XTD9
• System with motor movement is still unsatisfactory (see above)

Imagers

Status:

• 2 Imagers in XTD2 have no trigger signal. Suspicion is that this might be configuration problem. P. Gessler will investigate
• One pop-in (245) in XTD9 cannot be reached with IP. Suspicion is incorrect network configuration -> K. Fillipakopoulos

SPB Tunnel components

• Signal pins of the Attenuator crate were tested. DC voltage is seen there at different levels on different pins. This looks problematic -> P. Gessler

Karabo:

Status:

• Ran stably over the weekend 

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Take equipment and junk out of tunnels
• Check trigger cabling for imagers in XTD2
• Check PBLM motor movement and continue testing in XTD9

Other topics

• Controlled access to tunnels is possible after 1500. Coordination with T. Haas and the DESY run coordination

All trigger problems in XTD2 and XTD9 solved except for one: spb_xtd9_imgpi, probably a cabling issue on the camera side.

IP address problem for camera of sa1_xd2_imgpii45 solved.

Tunnels XTD2 and XTD4 are closed, XTD9/10 remain open

Vacuum:

• Running stably
• Work continues on M3 in XTD9 and on the vacuum in XTD10 

EPS Loop:

• Input from undulator still missing. This requires  fixing a cable in balcony rooms and then testing

PBLM/Motion Loop:

• Work on the PBLM motors (ELMO controller) continues.
• It appears that the uneven movement is due to improper setting of motor parameters

Imagers

• Trigger problem reported yesterday was due to a cabling issue. Apparently during work on the relevant rack cables were unplugged and then wrongly put back
• Network issue with pop-in (245) in XTD9 solved

SPB Tunnel components

• Crate with "problem on signal pins" was brought to the lab and checked. Everything was ok. Problem was due to spurious measurement.

Karabo:

• PSLIT was tested successfully yesterday
• Behaviour of Karabo when a loop goes down needs to be made more graceful. 
• Cleanup continues

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Prepare mirror M3 installation
• Continue testing of PBLMs in XTD9
• Continue testing of SPB tunnel loop

Other topics

• None
   

 Tunnels XTD2 and XTD4 are closed, XTD9/10 remain open

Vacuum:

• PLC/Karabo Running stably
• Local tests of ion pumps in XTD9 being done by J. Eidam
• Work continues on M3 in XTD9 and on the vacuum in XTD10 
• DPS in XTD9 should be integrated into the vacuum loop. This requires a cycling of the loop. Timing should be coordinated with WP74 because of XGM in XTD2. Unfortunately nobody from WP74 attended the meeting. Hence it was decided to perform the work tomorrow morning.

EPS Loop:

• Checks for the signal from the undulators and for the fast valve will be done with DESY MPS today

PBLM/Motion Loop:

• Work on the PBLM motors (ELMO controller) continues.
• Yesterday it was possible to align the screens 
• There is a resource problem when trying to read out the cameras. For this reason an additional server needs to be set up dedicated to acquiring the images from the cameras.

SPB Tunnel components

• Crate that was checked in the lab yesterday was moved back into the tunnel
• The unstable support of the imager was fixed
• B. Weinhausen and M. Messerschmidt are testing
• All modules necessary for loops 1 & 2 were received from Poland
• Waiting for the "Freigabe" of the cables for SPB Optics

FXE

• Loops 1,2 and 4 are waiting for input from EETF
• Loops 3&5 are running
• No visible testing activity from FXE team

Karabo:

• Cleanup continues

Tasks for today:

Note: All loops should be left running and no changes to Karabo.

• Prepare mirror M3 installation
• Continue testing of PBLMs in XTD9
• Continue local tests of ion pumps in XTD9
• Continue testing of SPB tunnel loop

Tasks for tomorrow:

• Cycle vacuum loop for inclusion of DPS in XTD9

Other topics

• Weekly SASE1 Readiness meeting tomorrow at 09:00 in XHQ 1.173
• L. Samoylova requests access to XTD2 to install another webcam
• Magnet current tests will likely continue through Wednesday in XTD2. Maintenance day to be shifted accordingly probably to Thursday/Friday. More information later

 In KW17 there will be NO maintenance day on Tuesday (25.04.) 

 
On Monday (24.04.) morning up to about 11:00 we will have the TÜV approval of CS8. During that time 
 NO access of "other people" to the XTL tunnel is possible. After the TÜV approval 
 up to 13:00 there will be the possibility for URGENT access to the XTL. Access requests 
 have to written to the logbook/access requests entry. 
 
The tunnel XTL/XTIN will stay in interlock, access will be possible by ZZ only. 
 
The northern branch XTD2->XS3->XTD4->XDU2 will stay closed, in order not to interrupt the 
 magnet commissioning.

XGM status 21.4.2017

During Easter break, the two XGMs in the control system (XTD2+9) had no issues.
XGM@XTD10 however had an issue: tuesday morning it was found that all pumps had stopped. The scroll pump showed an error. UPS apparently had excess load sunday evening 19h30 but couldn't send email (network error). Possibly vented with tunnel air up to 10mbar since that time. Investigation is ongoing.

Thursday enabled DOOCS pressure reading of XGM in XTD10, UPS rechecked

System surveillance on coming weekend: Jan and Theo 1 day

Other remarks:
- WP74 staff have received their dosimeters for ZZ access if required
- some automatic monitoring and info system is needed soon, e.g. karabo to NAGIOS connection

exflplcgwSA1 seems not reachable. This inhibits support for the PLC systems.

Dear all,

The service of On-call Duty will be available from AE group during weekend in this number: 6442

Please make a post with the OCD numbers from CAS, WP74 and WP73.

Thank you and bests.

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

Have a nice week-end, Sandor

XTDs Info:

Tunnel XTD2 will be accessible this Thursday, 27.04. between 9 and 12. Dosimeter and General radiation training required. Access requests should go to T.Haas.

XTD10 will be closed starting from this Thursday, 27.04. at 12:00

Provided that the authorities give the "go ahead", DESY plans to put beam in XTD2 on Thursday's evening.

Karabo:

• System running  but performance of the GUI still sluggish
• There appears to be a resource leak. Second server will be set up tomorrow as workaround. Experts are working on it.
• In parallel experts are working on a definitive solution
• Deployment today on a new beckhoff device for the decodification of PLC error messages.

Vacuum:

• Systematic tests of ion pumps started again

PBLM/Motion Loop: 

• There is a resource problem when trying to read out the cameras. This problem will be reconsidered once the general issue with the GUI server is solved.
• ASilenzi will ask Natalia for acceptance test definition for PBLM
• Motion loop will be down until 10:30 for update. An entry will be written when the loop is again up. 

SPB Tunnel components

• The Renishaw encoders can be read and positions are reliable. An error message is coming from the encoder and is probably due to a wrong voltage level delivered to the encoder. The encoders can be operated in this condition.
• T. Freyermuth is in contact with the encoder company tu understand the problem and work on a fix
• The same problem also affects FXE components
• The cameras operated at 1Hz deliver delayed images. 1/3 Hz operation (almost live mode) is OK - probably related to GUI memory issues

FXE

• Encoders of Loop1 have the same error message as SPB - the encoder positions are reliable - local components test can go on (e.g. OGT1)
• Encoders of loop2 are not powered - AE to investigate

Tasks for today:

• Identify a fix/workaround for the GUI server resource problem
• Deployment of a beckhoff device for the decodification of the error messages.
• Find a solution for the Renishaw encoder problem SPB Tunnel/ FXE Loop1
• Investigation of the FXE Loop2 encoders power
• Continue testing of ion pumps in XTD9
• Test of gas section interlock in XTD9

Tasks for tomorrow:

• Setup of the second server for karabo GUI

Dear all.

Motion loop is running again.

Thank you

Dear all,

We have to make some changes again into the Motion loop. Therefore I will do an update at 14.45h.

I will keep you inform when it is running again.

Thanks!

Dear all,

We need to update the Vacuum loop in order to correct and add some configuration to the interlock conditions.

It would be running in few minutes again.

Thank you!

Vacuum is running again and Motion also, yesterday I forgot to update you about the Motion PLC.

Sorry and best regards,

Dear all,

I will do an update of the motion loop so the PBLM could be tested. I will do it know and the PLC will be again available in few minutes.

Thank you!
