Question: Model:'coupling_loss_CH1', all time normal: [ NAME_1, NAME_2], all time abnormal:[], normal to abnormal:[]
Answer: CH1 coupling loss values on NAME_1 and NAME_2 are normal for both the time ranges. On the rest of FBN NAME_3 machines CH1 coupling loss values went from abnormal to normal for time range one to time range 2. [EOS]
Question: Model:’da_power', all time normal: [ FLA], all time abnormal:[FLA01, FLA02, FLA03, FLA05], normal to abnormal:[]
Answer: DA power values on all FBN FLA machines in production and online are not in normal operating condition for both time ranges. This highlights some serious common root cause underlying. [EOS]
Question: Model:'blt_da', all time normal: [ ], all time abnormal:[], normal to abnormal:[]
Answer: BLT DA values on all FBN FLA machines in production and online were deviant from normal operating conditions for first time range, but restored to normal conditions for second time range[EOS]
