Since the 1st of September 2017 all elevator controls have to meet the latest requirements of the standards EN 81-20:2014 and EN 81-50:2014.
Compared with conventional safety relay, the safety components for the use in elevators have to fullfill higher requirements with regard to e.g. creepage distances and clearances, mechanical stress (shock / vibration) as well as increased error protection.
The EN 81-20:2014 defines guidelines for the design and technical characteristics of safety components for elevators as well as the framework, which has to be observed during the installation of lifts.
Whereas the EN 81-50:2014 determines how the testing of the components and elevators has to be carried out.
For example, all elevators has to be equiped with light curtains at the doors and have to ensure an improved stopping accuracy.The new Zander safety relay SR3E is especially designed for the use as a safety component for elevators according to the latest version of the approvals EN-81-20:2014 and EN 81-50:2014 and is certified by TÜV Rheinland.
