Fault Status
The present fault is output as a combination of pulses. The output can be fed to
an optional output DO1 to DO7 depending on the configuration.
Depending on the selection of the pull-down menu the entry fields „WINDOW" and
„Debounce" appear. "WINDOW" has to be configured with the value for the selected
condition. "Debounce" has to be configured with the time the fault condition has to be
present before the Digital Output is set.
The last column presents the opportunity to invert the signal.
