A guard door monitoring system comprising a guard door monitoring module for monitoring a state of a guard door to a safety area. The guard door monitoring system also comprises a control unit, configured to analyze a guard door signal generated by interaction between an actuator and a sensor, and to control a machine or system located in the safety area depending on the guard door signal. A locking device with a main body and a locking lever arranged on the main body is additionally provided. The locking lever can be moved relative to the main body from a release position into a blocking position in which the locking lever prevents the interaction between the actuator and the sensor, wherein the locking device comprises a receptacle for a lockable securing part, which, when introduced into the receptacle, keeps the locking lever in the blocking position.

1. A guard door monitoring system, comprising: a guard door as an entrance to a safety area,a guard door monitoring module for monitoring a state of the guard door, having an actuator and a sensor, which can be brought into interaction with one another in an electrically contactless manner and thereby generate a guard door signal,a control unit, which is configured to analyze the guard door signal and to control a machine or system located in the safety area depending on the guard door signal, anda locking device with a main body and a locking lever arranged on the main body, wherein the locking lever is mechanically pivotable relative to the main body about a pivot axis from a release position into a blocking position in which the locking lever prevents the electrically contactless interaction between the actuator and the sensor, wherein the locking lever is coupled to the main body via a spring element which is arranged along the pivot axis, wherein a first and a second recess are provided on the main body, wherein the first recess is delimited laterally by at least one first sidewall and the second recess is delimited laterally by at least one second sidewall, wherein, when the locking lever is in the release position, the locking lever is arranged in the first recess, the at least one first sidewall prevents the locking lever from pivoting about the pivot axis, and the spring element exerts a spring force that pushes the locking lever against the main body, wherein, when the locking lever is in the blocking position, the locking lever is arranged in the second recess, the at least one second sidewall prevents the locking lever from pivoting about the pivot axis, and the spring element exerts the spring force that pushes the locking lever against the main body, wherein the locking lever must first be moved in a direction of said pivot axis against the spring force of the spring element to free said locking lever from said first recess and said second recess, and thereby enable pivotable movement of said locking lever from said release position and from said blocking position, respectively, and wherein the locking device comprises a receptacle for a lockable securing part, which, when introduced into the receptacle, keeps the locking lever in the blocking position. 2. The guard door monitoring system as claimed in claim 1, wherein the guard door monitoring module further comprises an electromagnet for a magnetic locking of the guard door. 3. The guard door monitoring system as claimed in claim 1, wherein the locking lever, when in the blocking position, prevents the electrically contactless interaction between the actuator and the sensor by mechanically distancing the actuator and the sensor from one another. 4. The guard door monitoring system as claimed in claim 1, wherein the guard door is a first or second part of a guard door system, wherein the sensor is arranged on the first part of the guard door system and the actuator is arranged on the second part of the guard door system, wherein the two parts of the guard door system are separated from one another when the guard door is opened. 5. The guard door monitoring system as claimed in claim 4, wherein the locking device is arranged on the first part of the guard door system. 6. The guard door monitoring system as claimed in claim 4, wherein the locking device is arranged on the second part of the guard door system. 7. The guard door monitoring system as claimed in claim 1, wherein a holding grip is provided on the locking lever for pivoting the locking lever by hand, said holding grip running substantially along the pivot axis. 8. The guard door monitoring system as claimed in claim 1, wherein the receptacle for the lockable securing part is formed as a bore in the locking lever. 9. The guard door monitoring system as claimed in claim 8, wherein a third recess is provided on the main body, wherein said third recess, when the locking lever is in the blocking position, is at least partially aligned with the bore provided in the locking lever. 10. The guard door monitoring system as claimed in claim 1, wherein two bores are provided in the locking lever each as the receptacle for the lockable securing part, and two additional recesses are provided on the main body, said additional recesses, when the locking lever is in the blocking position, are at least partially aligned with the bores provided in the locking lever.
