Properties of the F-Switch PROFIsafe Electronic Module
Behavior in Case of Supply Voltage Failure
Failure of sensor supplies Vs1 and Vs2 is indicated by the SF LED, the VsF LED, and the
LEDs of the relevant channel group on the F-module. This information is also provided on
the F-module (diagnostic entry). All channels of the F-module are passivated.
Diagnostic Functions
The following table shows an overview of the diagnostic functions of the F-Switch PROFIsafe
electronic module. The diagnostic functions are assigned either to one channel or to the
entire module.
