Abstract

The present invention is directed toward a method for operating a vacuum generator using pressure fluid to generate the vacuum. The vacuum generator has a pressure port for pressure fluid supply, and a suction point. During a work cycle, the pressure fluid supply is activated at least once and then deactivated again at least once. An active period is measured during which the pressure fluid supply is activated during the work cycle.
