FAULT RESPONSE WINDOW
The
Fault Response
window programs the fault response for all
the voltage, current, temperature, and GPIO faults, 22 in total.
Each fault has a configuration with a programmable debounce
time, and the response to the fault followed by the delay time
between consecutive soft starts if the PSU is shutdown as a
result of the fault action.

Figure 37. Current Fault Response Monitoring
The first fault ID (FFID) that caused the PSU to shutdown is
displayed in a monitoring window.
A complete description of the fault response can be found in the
data sheet.
