The function did not operate for this forward EF now because the injected current
is below the set level.
OperationMode = Start and Trip in order to obtain the trip signal
IN>=3% (minimum value) in order not to interfere with this pickup test
IMinReverse =2.5% in order to be similar to the IN value
