Safe Operating Mode Selection
Today's complex machines need the ability in certain situations to permit an operating mode at reduced speed or without monitoring of certain protective devices. This is now possible using so-called “safe operating mode selection.”
Bihl+Wiedemann makes it possible to easily implement safe operating mode selection up to PLe, with maximum convenience for the end user over a standard HMI. Access authorization for safe operating mode selection is supported using a normal safe key switch or an electronic key system.
Principle of the Safe Operating Mode Selection
The operating mode can be safely selected and activated using a standard HMI such as a touch panel. Access to this selection is by means of a key which is restricted to authorized persons. This can be either a mechanical or an electronic key (such as the Euchner EKS-FSA).
Full Flexibility for your Machine
- Five different operating modes with different safety functions are freely configurable
- Independent, centralized configuration of up to six different instances, e.g. for six different system parts
This way, you can set different system parts independently to different operating modes.
