Method for checking functionality of vibrating conveyor device

The invention relates to a method for checking the functionality of a vibrating conveyor device (1) by means of a state analysis, which is carried out before or during the operation of the vibrating conveyor device (1), in which A) the method to be carried out before the operation comprises the following steps: A1) applying a drive pulse to a drive device (2); a2) detecting an impulse response caused by the vibrating conveyor device (1); a3) sending the detected impulse response to a computer (6) by means of the signal evaluation unit (5); a4) comparing the detected impulse response with a reference impulse response by means of the computer (6); and A5) determining by means of the computer (6): a) whether a start-up program for operating the vibrating conveyor device (1) with reduced start-up drive power should be activated or b) a start-up program for operating the vibrating conveyor device (1) without a reduction in start-up drive power should be activated or c) operation should be interrupted; b) the metho
