Positioning and control systems
APS
The APS is a contactless absolute positioning system for elevators. It supports speeds of up to 20 m/s and distances of up to 1,500 m. As SIL 3 rated, it can be used for safety-relevant functions.
The contactless, SIL 3-rated, twin IR-camera system on the elevator car continuously reads the APS code tape mounted along the elevator shaft. The position and velocity information of the elevator car is then transmitted to the elevator controller through customer specific interfaces such as CAN. Because the APS code tape can be mounted on guide rails, C-profiles, landing door operators or landing door sills, the APS fits into every elevator configuration, including modernization and retrofitting projects.
