SPB_XTD9_IMGPII45 lost steps - REPAIRED |
|
|
REPAIRED / FIXED
Problem: The imager SPB_XTD9_IMGPII45 insertion motor lost steps and kept the machine to maximum 2 bunches per train.
Mitigation by DOC/EEE/PRC on 8 April 2023: made sure that screen seems actually out of beam and took imager out of interlock condition.
"Repair" by XPD on 10 April 2023 02h15:
a) recalibrated OUT position.
b) verified that EPS-OUT switch shows green when moving to OUT position in MDL.
c) put back the imager into the interlock conditions.
d) communication with BKR before and after the intervention (SPB and FXE didn't use the beam).
