Abstract (en)
[origin: EP0751088A1] The device consists of transducers (10,11) arranged near the door of the lift cabin (1) and actuation elements (12) near the doors (8) of the shaft (4) which activate the transducers according to the position of the lift cabin in the shaft. Optoelectronic transducers are used. A transmitter bar (10) extending above the cabin door height which produces a light curtain (9) contains light sources arranged one above the other. A receiver bar (11) extending above the door height contains light receivers arranged one above the other which convert the light beams from the sources into electrical signals. Individual light beams are interrupted by cover plates mounted near the shaft doors and protruding into the light curtain.
