摘要:
A switching arrangement for returning a people-conveying device to a state of readiness comprises a plurality of light barriers which are formed by emitters and receivers and whose signals are fed to at least one electronic evaluation device, which automatically returns the people-conveying device to a state in which it is ready for use after an emergency off switch has been activated. The individual emitters and receivers are combined to form a light barrier chain and are disposed approximately opposite one another at predetermined spacings. Emitters and receivers are provided alternately on each side of the people-conveying device. The wiring between individual emitters and receivers on each side of the people-conveying device is brought about by plug-in connections without any connections to the emitters and receivers on the opposite side.
