Regular checks
Check safety devices regularly, every year at the very least, to ensure they function correctly. Refer to EN 12453:2000.
Safety devices that are sensitive to pressure (e.g. safety switch unit) should be checked every four weeks to ensure they function correctly,
see EN 60335-2-95:11-2005.
