Abstract: Techniques operate a safety processing installation. Such techniques involve remote operation using a radio remote control unit and a controller assigned to the safety processing installation. A distance monitoring unit determines a distance between the radio remote control unit and the controller. Such components are able to communicate with each other to derive an enable signal for a safety processing procedure from the distance D transmitted from the radio remote control unit or the distance monitoring unit to the controller or the radio remote control unit or a signal corresponding to the distance D and a predetermined safety distance D min, and accordingly to transmit the enable signal to the controller. The controller is additionally configured to trigger a safety processing procedure on the basis of the presence of a user-induced start signal and the enable signal in the controller.
