Metal Bolt
According to EN 292-2, movable safety guards must be equipped with an interlocking device, with or without guard locking.
Here it must be ensured that:
– dangerous machine functions are stopped as soon as the safety guard is no longer in the closed position
– dangerous machine functions are not started when the movable safety guard is closed.
When the EUCHNER safety door bolts are opened intentionally, the actuator mounted on the handle is pulled out of the safety switch actuator head. The opening of the NC contacts in the safety switch fulfills the requirements of the safety standard given above and permits access to the protected space.
In addition to the standard bolts, Euchner supplies bolts with escape release as per the EU Machinery directive. These bolts facilitate opening of the locked safety guard from within the danger area to allow operating personnel to escape and prevent them being accidentally locked in the danger area.
