reached and remains in this condition for a timeframe equal to or exceeding the alarm minimum time (DAL #
parameter).Itisrestoredinnormalconditionswhentheweightvalueisdropped

sum ofthe thresholdvalue and the configured hysteresis value (DB# parameter) and remains in this condition for a
