Module
Behavior in Case of Supply Voltage Failure
Failure of sensor supplies Vs1 and Vs2 is indicated by the SF LED, VsF LED, and the LEDs
of the relevant channel group on the F-module. This information is also provided on the
module (diagnostic entry). All channels of the module are passivated.
Diagnostic Functions
The following table presents an overview of the diagnostic functions of the 4/8 F-DI/4 F-DO
DC24V/2A PROFIsafe electronic module. The diagnostic functions are assigned either to
one channel or to the entire module.
