A.7.2.7 Auto Fault Recovery
The converter output is automatically muted in the event of a detected fault. Auto Fault
Recovery, if enabled, will cause the output signal to go active (unmuted) if all faults clear. If
disabled, the output will remain muted even after all faults clear until a MUT_OFF command is
received (see 4.8.2.4). If Auto Fault Recovery is enabled and the converter detects the same fault
more than five times in a five minute interval (ex: multiple IFLO lock detect faults) the function
reverts to DISABLED and the converter remains muted. The default is ON.
