Abstract
A safety locking device for a movable guard serves to safeguard a machine. The safety locking device is configured to communicate with a safety control apparatus. The safety locking device comprises at least a first radio module for contactless communication with a portable operating unit. The safety locking device is configured to contactlessly receive a selected command from the portable operating unit and to transmit it to the safety control apparatus.
Claims14
A safety locking device for a movable guard for safeguarding a machine,
- wherein the safety locking device is configured to communicate with a safety control apparatus and wherein the safety locking device comprises at least a first radio module for contactless communication with a portable operating unit,
- wherein the safety locking device is configured to contactlessly receive a command selected by a user on the portable operating unit from a plurality of selectable commands from the portable operating unit and to transmit it to the safety control apparatus,
- wherein the safety locking device is configured to communicate with the safety control apparatus and wherein the safety locking device comprises at least a first radio module for contactless communication with a portable operating unit,
- wherein the safety locking device is configured to contactlessly receive the selected command from the portable operating unit and to transmit it to the safety control apparatus,
- wherein the safety control apparatus is configured to receive and to execute the selected command,
- and wherein the safety control apparatus is further configured to transmit at least one currently executable command to the safety locking device in dependence on the executed command, with the safety locking device being configured to contactlessly transmit this further currently executable command to the portable operating unit.

An assembly comprising a safety locking device and a safety control apparatus,
- wherein the safety locking device is configured to communicate with the safety control apparatus and wherein the safety locking device comprises at least a first radio module for contactless communication with a portable operating unit, wherein the safety locking device is configured to contactlessly receive a command selected on the portable operating unit from a plurality of selectable commands from the portable operating unit and to transmit it to the safety control apparatus, wherein the safety control apparatus is configured to receive and to execute the selected command, and wherein the safety control apparatus is further configured to transmit at least one currently executable command to the safety locking device in dependence on the executed command, with the safety locking device being configured to contactlessly transmit this further currently executable command to the portable operating unit,
- wherein the safety locking device is configured to communicate with the safety control apparatus and wherein the safety locking device comprises at least a first radio module for contactless communication with a portable operating unit,
- wherein the safety locking device is configured to contactlessly receive the selected command from the portable operating unit and to transmit it to the safety control apparatus,
- wherein the safety control apparatus is configured to receive and to execute the selected command,
- and wherein the safety control apparatus is further configured to transmit at least one currently executable command to the safety locking device in dependence on the executed command, with the safety locking device being configured to contactlessly transmit this further currently executable command to the portable operating unit.
2 more elements
A method for safeguarding a machine by means of a movable guard, the method comprising the following steps:
- coupling a portable operating unit to a safety locking device or to a door system comprising a safety locking device;
- transmitting possible executable commands to the portable operating unit;
- receiving a user selection made by a user on the portable operating unit from a plurality of selectable commands;
- transmitting the command selected by a user on the portable operating unit to the safety locking device or to the door system comprising the safety locking device;
- transmitting the selected command from the safety locking device or from the door system comprising the safety locking device to a safety control apparatus;
- and
- executing the selected command by the safety control apparatus,
- wherein the safety locking device is configured to communicate with the safety control apparatus and wherein the safety locking device comprises at least a first radio module for contactless communication with a portable operating unit,
- wherein the safety locking device is configured to contactlessly receive the selected command from the portable operating unit and to transmit it to the safety control apparatus, wherein the safety control apparatus is configured to receive and to execute the selected command,
- and wherein the safety control apparatus is further configured to transmit at least one currently executable command to the safety locking device in dependence on the executed command, with the safety locking device being configured to contactlessly transmit this further currently executable command to the portable operating unit.
