(84) under Rule 4.17: Declarations of inventorship (Rule 4.17(iv)) — 1-1 ,_ 1 (54) Title: METHOD FOR IDENTIFYING SNORING 1-1 in (57) : The invention relates to a method for stopping a submersible pump when the pump is snoring, wherein the pump GP is operatively connected to a control unit. The method is characterized by the steps of regulating, by means of the control unit, the ON operational speed of the pump in order to direct an average power of the pump towards a predetermined set level, determining whether 1-1 ---.. the instantaneous power of the pump is outside a predetermined range, by monitoring at least one of the parameters: power [P], current L ---- [I] and power factor [cosy], determining whether the operational speed of the pump is increasing, and stopping the pump due to snoring, 1:::: ) by means of the control unit, when the instantaneous power of the pump is determined as being outside the predetermined range at the N same time the operational speed of the pump is determined as increasing.
