13.4 Generator electrical fault
In case of a generator electrical fault, the generator breaker is opened and the alternator is de-excited (if
wired) during a certain time [E1265]. If the fault is still present after this time has elapsed, a hard shutdown
occurs. Otherwise GENSYS 2.0 will try to re-synchronize. Associated parameters are listed in the table
below.

NOTE:
Never use “No start on fault” in conjunction with "open mains on fault" in permanent mode
or no break change over mode.
Always use “No start on fault” when "generator breaker" or "both breakers" to open is
selected.
