Monitoring device
First Claim
1. A monitoring device for a protected area of a machinery installation, the protected area being accessible through at least one access opening which can be closed off by a movable element which is movable between an open position and a closed position, the monitoring device comprising a safety switch having:
- a housing arranged adjacent to the movable element, the housing defining a receiving space;
an evaluation device disposed within the housing;
an actuator mounted on the movable element, the actuator being pivotally movable in a pivoting direction between a locking position and an unlocking position, having an end portion received within the receiving space of the housing when the actuator is in the locking position, and defining a groove which extends in the pivoting direction;
handle means for moving the actuator between the locking and unlocking positions;
a coded release mechanism mounted on the end portion of the actuator;
read head means positioned within the housing for reading data stored in the coded release mechanism when the actuator is in the locking position; and
a locking pin arranged in the receiving space of the housing;
wherein the groove of the actuator receives the locking pin when the actuator is in the locking position.

Abstract
A monitoring device for a protected area of a machinery installation, the area being accessible through at least one access opening which can be closed off by an element, such as a door, shutter, or the like, which is movable between an open position and a closed position. The monitoring device being arranged adjacent to the movable element and comprising a safety switch having a housing, an evaluation device, a movable element positionable between a closed and an open position, a coded release mechanism located on the movable element, and a read head for reading the coded release mechanism when the movable element is in the closed position. The safety switch being further provided with an actuator bearing a release mechanism, and which, in a locking position in the housing, locks the movable element in its closed position. The housing having a receiving space for the actuator such that the release mechanism is located adjacent to the read head when the actuator is in the locking position in the housing. The actuator being movable in relation to the movable element by coupling to a handle provided on the movable element.
