P8 cryogenic PLC problems on 25.05.2011 LHC operation daily meeting 27.05.2011 Krzysztof Brodzinski, Serge Claudet_TE-CRG-OA

History P8: 25.05.2011 11:00 - PLC problem of Cold Compressor Station (1.8 K unit) - diagnostic + PLC replacement 13:00 - Restart of Cold Compressors and cryo recovery 15:30 - Cryo operation problem (lost of ~ 1 hour) 16:30 - Restart of Cold Compressors and cryo recovery 18:00 - PLC problem on Main Warm Compressor Station (ref. 4.5 K) - diagnostic +PLC replacement 19:00 – Complete restart and cryo recovery For information: Estimated recovery time after stop of Cold Compressor  10 hours +/- 10% Estimated recovery time after stop of Warm Compressor Station  24 hours +/- 10% (Both estimations are applicable in case of one cryo plant supplying two sectors, applicable if immediate restart applied) TE-CRG-OA_K.Brodzinski_27.05.2011

Localization QSCB PLC problem on 13.05.2011 – not replaced Radiation problem NOT possible QSCB PLC problem on 25.05.2011 – replaced Radiation problem NOT possible QURCB PLC problem on 19.04.2011 – replaced Radiation problem possible QURCB PLC problem on 25.05.2011 – replaced Radiation problem possible Equipment not in operation – one cryo plant supplies two LHC sectors Detailed explanation of the problems origin should be given by EN/ICE experts TE-CRG-OA_K.Brodzinski_27.05.2011
