General Announcement:
- It had been a cooling water issue with SA1 and SA3 PPLs on Saturday. Other groups are encouraged to check their components for eventual damage. Cooling water is back 
again.
- Change on definition of a critical work: everything that leads to operation is from now on considered a critical work (official communication will be send by e-mail).
- Tomasz J. says interlock tests in SA1 tripped the laser interlock due to the Seeder connection to the interlock. 
Andreas G. says there are care been taken to prevent this in future. More discussion will follow.

CTRL:
- Updates were done on the time servers and data loggers.
- GUI servers will be done this week as there was no access to GITLab. Current suggestion is next Wednesday morning before 08:00AM. 
Each topic will take a few minutes only. XPD is fine with the proposed day/time.

DA:

EEE:
- Issue during weekend: signals to the absorber. EEE and PRC (Maurizio V.) will coordinate when it is the best time for applying the final fix. 
EEE needs to mask it for proceeding with the work.

VAC:
- VAC OCD was involved in the absorber EPS issue.
- Today around lunchtime the XTD6 and XTD9 will be closed.

XPD:
- EPS issues: any component driven to the beam was not protected by many bunches operation. The EPS was thinking the PNACT was closing but in reality, it was opened.
PRC/EEE/VAC/XPD OCDs solved by manually telling the system it is closed.
- Wrong bunch number sent to XGM: SA3 toroid was moved to a different position and the old name was not valid anymore. 
Info from this toroid was not received and the consequence XGM was receiving wrong bunch numbers. This makes impossible for the XGM to calculate correctly the number of 
bunches. 
Doocs servers were not updated (these programs would need to be informed of new naming).

are related to MC2 motors. 
CTRL will get in touch with EEE in an offline discussion. Issue has a different nature compared to the HED problems with motors.

- EEE received report last Monday from SPB with issues on motor cables from Beckhoff controllers. Electrical current could go very high but not enough to trigger the 
fuses and consequently overheats and has a fire risk. 
EEE is looking implementations to take place this week in crates. Ordered parts shall arrive beginning of this week. 
It is a large intervention to introduce 1-2 fuses in the modules/terminals of all crates in tunnels and experimental Hall. 
- Steve A. adds that the changes are piece cases, each crate will be touched; if 50% of the crates are changed during this maintenance, one reduces 50% the chances for 
fire. 
P. Gessler comments that one has to limit the current of the 24V terminals, by introduction the additional fuse. All crates will be touched but it is a linear change.

General Announcement:
- We would like to remind groups that the deadline for submitting to XO the feedback on the planned activities for the Summer/21 maintenance time is on April 30rd. 
In case of questions please contact XO via xo-planning@xfel.eu

CTRL:
- Updates announced on last XO Int. meeting will take place next Monday (unless if a group protests). This means a short downtime on data loggers in tunnels. An e-mail 
with a reminder will be sent.
- Upgrade for the bunch pattern statistics devices to take place (also will be offline for few minutes).
- Issues with MC2 motors: the workaround is to shutdown device and click/instantiate device. A fix will be deployed.

DA:
- DA involved and continuing with "Moonshot" coordination meeting.

EEE:
- Nothing to add.

VAC:
- Nothing to report.

XPD:

DET:

ITDM: 
- Announcement with respect to Maxwell cluster: ITDM will change partition schemes in the next Summer maintenance. 
Three new partitions will be introduced, for calibrations and a special one for reservations for beamtime (UPEX related); 
A new feature is that if Maxwell is full of jobs, one can pre-empty it by killing jobs and putting back in the queue.

XRO:
- Yesterday beam going to HED: some problems were found regarding parameter configurations. 
XRO reminds SA2 instruments to be careful and check devices positions and parameters are they may be changed in relation to April 1st due to the issue with PLCs during 
Easter Sunday. 
- Zunaira A. says there were problems with CRLs arms configurations. Some devices had to be restored but worked normally.

LAS:
- All lasers are fine. 
- Shutters in SA1 PP-Laser were in maintenance mode - without defined reason.
- SA2 PP-laser is fine. 
- SA3 PP-laser has degradation due to the cleaning. XO will address the issue with LAS.

UNSYS:
- All fine.

SPB:
- Running user experiment. Low photon energy yesterday (0.8mJ) and drop intensity over the full 352 bunch train but today it got better.

FXE:
- Nothing to add.

MID:
- All fine.

HED:
- All motors lost positions, e.g. mono, screens being driven (some in and not supposed to be in). CRL1 issue the position was lost at the axis; motors not being homed; 
Zuzana K. will summarize main issues and forward to XO.
- Steffen H asks for a summary of encoders and Zunaira A. also asks on the use of interlocks and CRLs/shutter to evaluate if all is fine. Zuzana K. says HED did not work 
yet on the CRL2 but will communicate as soon as experience is get.

SCS:
- Question to CTRL on the workaround of MC2 motors. Steffen H. says to shutdown device, check configuration and instantiate it again. An instruction e-mail will be sent 
to readiness list.
