LVPS Trip monitoring in 2015

Current trip status is given on trip monitoring chart. All manual interventions are removed based on the table shown below.

Module Trip time Symptom, problem found DCS image
EBC10 2015.07.05 06:19.16 trip? https://atlasop.cern.ch/elisa/display/267540

<fc #FF0000>EBC26</fc> 2015-04-04 15:10:21 REAL trip https://atlasop.cern.ch/elisa/display/256790
LBC03 2015-04-09 06:07:10 NOT a real trip, power cycles requested by DAQ FSM
LBC31 2015-04-03 10:01:31 NOT a real trip, the module was due to discarding events and auto power-cycled many time. It was off at ~0:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256633 and was switched on again ~13:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256669. The problem was fixed by using 2nd readout fiber https://atlasop.cern.ch/elisa/display/256668
LBC31 2015-04-03 02:00:00 NOT a real trip, the module was due to discarding events and auto power-cycled many time. It was off on ~0:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256633 and was switched on again ~13:00 on April 3, 2015 https://atlasop.cern.ch/elisa/display/256669. The problem was fixed by using 2nd readout fiber https://atlasop.cern.ch/elisa/display/256668
