    keyword=BB chamber HV alarm

    around 23:30 BB wire chamber HV tripped without any alarm. Later Yi find the problem from online replay. Then we found the error shown in the gui. Before it had an alarm to notice shift worker. Now we don't why the alarm doesn't work. I'm sure the audio was on. So please look at the HV gui periodly and ask the shift work keep eye on that.
