摘要: An interlocking device for locking a movable safety guard has a locking unit, an electric mover, an additional release unit, a sensor device and an evaluation unit. The locking unit is movable between a locking position for interlocking the movable safety guard and a release position for releasing the movable safety guard and the mover is configured to move the locking unit between the locking position and the release position. The additional release unit is movable from a neutral position into an additional release position to move the locking unit from the locking position into the release position. The sensor device is configured to detect a position of the locking unit and a position of the additional release unit. The evaluation unit is configured to output a locking signal, a normal release signal, and an additional release signal.
