After jump into latched fault mode F wait
200ms A single restart attempt after delay of internal timer
Reset of failure latch in run mode after
40s Reset of failure latch by UVLO or 40 s in run mode
S = Start-up condition, N = No fault, A = Auto restart , U = Undervoltage
F = Fault with a single restart; a second F leads to a latched fault
Note: All values @ typical 50 Hz mains frequency
