SAFE SHAFT COPYING SYSTEM LES, Fulfills EN81-20/21/50 Requirements
Absolute position measurement. LES is an extremely robust, compact and contactless SIL3 certified measuring system. Elevator car absolute position values are measured slip-free with a resolution of 1 mm and a traverse speed of 5 m/s. Additional components such as magnetic switches are no longer needed. Especially the easy mounting reduces installation time, thus contributing to overall costs reduction.
Applications
In conjunction with a safe elevator control / evaluation unit, this SIL3 certified measuring system for safe elevator car position determination allows realizing numerous safety functions required by standard EN81-20/21/50. The absolute position measurement allows doing without many additional components such as magnetic switches.Installation work is therefore reduced contributing, in addition to the drop in costs for additional components, to overall costs reduction. In addition, the SIL3 certification simplifies the certification of the complete elevator.
