Appendix A MN-DT4500A
A–17
A.7.2.7 Auto Fault Recovery
The converter output is muted automatically 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. 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.
