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.

bunches. 
Doocs servers were not updated (these programs would need to be informed of new naming).

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.

- Upgrade on instruments are coordinated by ICIs; Updates of Mc2 motors today.
- Z. Ansari asks if updates of MID will affect interlocks as well; Valerii B. answers this is a Karabo update and not PLCs, so no effect is expected.
- On recent days CTRL finds Karabo broker pileup and this was successfully understood; DOC was preventively monitoring it and fixed it beforehand.

DA:
- No OCD calls for DA; 
- Collaboration and preparation for supporting SPB/SFX last week and for beamtime continuation in two weeks.

EEE:
- Today 08:30 it was found SA1 tunnel racks lost power. The uTCAs were also down but not the one in room 1.14. It affected SA1 tunnels loops such as Vacuum and motion.
The guess is on a power glitch. XO will bring up to the machine side and eventually correlated with the Easter Sunday's event.

VAC:
- Recovering the SA1 tunnel loops from 08:30 downtime. All seems to be fine right now.
- VAC asks if FXE is running cryo coolers. FXE tells they were running and will check the signals for possible issues.

- Experiment last week: quite successful and not many issues.

FXE:
- Nothing to add.

MID:
- All fine.

HED:
- A Motor on the CRL HED chamber was engaged and not moving (hardware issue). It may need a ZZ. It is not related to the CRL's arms.

ZZ accesses. 
XO states the power failure was man-made caused.
- Quad mover sudden move: Lars F. from MXL does not have records on the command given for the sudden move and therefore the root cause can't be traced.

SPB:
