Abstract
The invention relates to a modular safety switching device system for switching actuators fail-safely off. The system comprises at least one input module for fail-safely evaluating a safety transmitter and for generating an output signal. It further comprises at least one output module for fail-safely actuating the actuator in response to the output signal from the input module. At least the input module can be operated in different selectable operating modes. A control module is provided for individually setting the operating mode of the input module and, if applicable, of the output module. A display is provided for fail-safely displaying the operating modes set.
Claims21
A modular safety switching device system for actuating actuators in a fail-safe manner, said system comprising:
- a plurality of safety transmitters, each for generating a safety switching event;
- a plurality of input modules for fail-safely evaluating said safety switching events and for generating output signals;
- a plurality of output modules for fail-safely actuating an actuator in response to the output signals;
- and
- a control module and a display;
- wherein said input modules are configured to be operated in a number of different predefined operating modes;
- wherein said control module is adapted for setting a desired operating mode for each input module;
- and
- wherein said display is adapted for fail-safely displaying the operating modes set by the control module.
A modular safety switching device system for actuating an actuator in a fail-safe manner in response to a safety switching event received from a safety transmitter, said system comprising:
- at least one input module for fail-safely evaluating said safety switching event and for generating an output signal;
- at least one output module for fail-safely actuating said actuator in response to said output signal;
- a control module and a display;
- wherein said input module is configured to be operated in a number of first different operating modes;
- wherein said control module is designed for setting a desired operating mode selectable from said number of different predefined operating modes;
- and
- wherein said display is adapted for fail-safely displaying said operating mode set.
