TripLockout: Sets the scheme for lockout. Off only activates the circuit breaker lockout output when
the input SETLKOUT is activated. On activates the circuit breaker lockout output and latches the
output TRIP when the input SETLKOUT is activated. The normal selection is Off.
AutoLock: Sets the scheme for lockout. Off only activates lockout through the input SETLKOUT. On
additionally allows activation of lockout from the trip function itself. The normal selection is Off.
tTripMin: Sets the required minimum duration of the trip pulse. It should be set to ensure that the
circuit breaker is opened correctly. Normal setting is 0.150 s.
