Problem: Beam operation in SASE2 is prohibited by SEPS / MPS
Origin of problem: HED-CRL3
(this was already an issue during the past weekend) |

SASE3 peration issue - SOLVED
Controls issue, the machine cannot make beam in SASE3.
From
BKR / DOOCS the problem description is: Big Brother is blocking SASE3 beam due to an EPS power limit of 0 Watt.
Looking into the SASE3 karabo topic, many devices are not instantiated, ATT #1.
The state of the PREABS preabsorber is not known |

SASE1 blocked to 1 bunch/train by EPS interlock (sic, not 2 but 1) --- PARTIALLY RESOLVED
Several issues:
1) MODEM device is broken, in state UNKNOWN, see ATT#1 and ATT#2. Fixed with deinstatiating and then using BECKHOFF_ASSISTANT to re-instantiate. |

ZZ Access on 24th January (19:30h) - Replacement of Motor on SASE2 Undulator - Cell 17 Phase Shifter, posted by Raśl Villanueva-Guerrero on 25 Jan 2023, 08:44

Dear all,
last evening Suren Karabekyan and myself did a short notice ZZ access to XTD1. The reason is that machine operators detected the lack of response
on the Cell 17 Phase Shifter. The intervention was successful and around 20:30 we left the tunnel. |

15:15 SCS called and reported an issue with one of the motors of the SCS exit slit. DOC already looked at the problem and could not make the motor
move. XRO (Maurizio) is now informed and looks at the problem
