The 2019 North American Elevator Safety Code (ANSI A17.1-2019 / CSA B44-19) defines new and clarifies existing requirements for the means of detecting persons or objects between the doors (2D) or approaching the elevator (3D). CEDES CabSafe™ system, consisting of a Controller, a 2D light curtain and a 3D TOF sensor, can fulfill all these code requirements and more.
The iDiscovery is a powerful SIL 3 and EN 81-20/50 compliant safety supervisor unit. In conjunction with CEDES’ APS (Absolute Positioning System), it takes over safety-relevant functions of the elevator, including enhanced inspection functions for elevators with reduced headroom or pit (EN 81-21). The system features a pure electronic overspeed governor
to trip an electrically activated safety gear.
The latest version of the cegard/Mini-CC light curtain meets every requirement under EN 81-20. Its criss-cross beams, which remain active up to complete elevator door closure, offer a major increase in elevator door safeguarding.
The Universal Power Supply (UPS) offers a 24 V power supply for sensors, e.g. cegard/Mini. Input voltages ranging from 20 to 265 VAC or 20 to 375 VDC can be converted. The sensor’s semiconductor output will also be converted to a potential-free relay contact.
The power line converter offers a 24 V power supply for sensors, e.g. cegard/Mini. Input voltages ranging from 85 to 265 VAC can be converted. The sensor’s semiconductor output is also converted to a potential-free relay contact.
