EN 1088:1995+A2:2008. The interlocking guards shall be designed and positioned so that opening one of them stops the movement of any dangerous part of machinery before any part of a person enters the danger zone. This can be achieved e.g. by the following: 1) movable guards being equipped with at least one position switch acting on the main switching device of the power circuit (e.g. valve, contactor) via the control circuit. The position switches shall either have mechanically actuated positive opening contacts and comply with EN 60947-5-1:2004, Annex K or they shall be proximity switches that are in accordance with EN 60947-5-3. As soon as the guard is opened, the position switch shall be positively and directly actuated by the guard and the control signal for the dangerous movement shall be positively interrupted; 2) using a trapped key interlocking device that is in accordance with EN 1088:1995+A2:2008, Annex E. There shall be sufficient keys to allow the removal of every guard within the system.
