 Hallo allerseits

Imager Status, 12.4.17

-          All imagers tested, motors and cameras, motion loop, EPS loop, for 3 imagers XTD2, and 3 imagers XTD9.

-          All blocking issues concerning tunnel closure solved.

-          Remaining issues:

o   Camera trigger, tbd. for 4 imagers.

o   Camera driver for SR imager, Photonic Science, tbd.

o   Camera of sa1-xtd9-imgpii45-cam-beamview not reachable via IP address, tbd..

o   Camera display is now at around 2 Hz, not yet full speed.

o   Store image function, tbd.

o   Firmware update to operate braking switches for homing procedure, tbd.

After the update of the PLC firmware, the imagers are in following status:

SR: auto gain off seems to work, correct image, screens are out. Beamview just crashed, I asked Alessandro and Dennis to have a look.

Pop-In: Everything fine.

FEL: strange image. We had this before, no idea what the reason is. I will keep trying.

Another update of the motion loop is planned later. Contact Nerea for details.

-

XTD2, FEL imager with Wajid

Screen, motor, switches - ok, minor braking switch issue.

LED, camera power – ok.

Filter, motor, parameter issue, should be solved now, to be tested again today.

EPS tests and SR imager tests, to be done.

XTD9 cameras, no power, will check today with Bernard.

Dear collogues,

all loops are up and running after deploying the hotfix.

Have a nice weekend,

 Confirmed from Karabo side.

Dear collogues,

we have added a hotfix to the framework, to make sure, that no motor can be moved if the feedback signals are missing. This update will be done due to the mentioned issue in the readiness meeting this morning.

We will update the loops again after the weekend, with a proper solution.

The hotfix will send all devices of a loop into error if the feedback of a terminal in the loop is missing.

I will write a new entire in the Logbook, if we are done with the updates.

Cheers,

    Tobias

 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.

The GUI server has been redeployed and a second one has been added.

In order to access those:

please log out of the gateway and log in again using the usual command

ssh desyusername@exflgateway -L 44444:sa1-br-sys-con-gui1:44444

or

ssh desyusername@exflgateway -L 44444:sa1-br-sys-con-gui2:44444

Dear all,

Tomorrow in the morning is needed to add some fuses in the PLCs crate, therefore Vacuum and Motion would be down for more or less one hour from 9am. I will notify you when the PLCs are available to work again.

Thank you,

FYI

Date: 13th of December 2017 between 09:00 a.m. and 11:00 a.m.


You don’t need to exit the building while the alarm occurs.

 

 ACTEMIUM has delivered the handover document for the phase II cables installed in D,02 and D.13. The beckhoff crates can be connected to the cables in these areas of SASE1.

Dear all,

the problem with the fast valves XTD9 tripping randomly is still not fully understood but we exchanged the controllers for both valves and they now seem to be stable. The valves are set back to active mode again with 1*10^-6 mbar trigger level while vacuum pressure at the sensors is around 1*10^-8 mbar.
