The present disclosure relates to a method for controlling at least one proximity sensor of a wind turbine, the wind turbine comprising a rotor shaft, the at least one proximity sensor being adapted to measure a radial displacement of the rotor shaft; the method includes: providing at least one reference value, detecting an output of the at least one proximity sensor, the output depending on a measured distance by the respective proximity sensor; comparing the detected output of the proximity sensor with at least one reference value. Further, the present relates to a control arrangement for a wind turbine, the wind turbine comprising a wind rotor shaft; wherein the control arrangement comprises at least one proximity sensor being adapted to measure a radial displacement of the rotor shaft, wherein the at least one proximity sensor is adapted to generate an output signal depending on a measured distance by the respective proximity sensor; wherein the control arrangement further comprises a control device, the control device being adapted to receive the output signal of the at least one proximity sensor, wherein the control device is adapted to compare the output signal with at least one reference value. Finally, the present disclosure relates to a wind turbine comprising a control arrangement.
