Abstract
A control device controls an elevator system in inspection mode, the elevator system having a safety circuit with at least one safety contact that is open in inspection mode and an inspection path for bridging the safety contact. The control device includes first and second operating elements for controlling the inspection mode and first and second switching units connected in parallel and each having a contact associated with a delay means. The switching units close and open their contacts in response to actuation and release of the first and second operating elements respectively. The contacts are series connected in the inspection path. The first and second delay means delay opening of the associated contacts by defined delay times after the release of the first and operating element respectively.
