Nos of self-reclosing operation before lockout.
Trip safe contact is actiavated by the recloser when the trip
safe contact de-activated due to leakage fault.
Fault detected immediately after the trip safe contact is
actiavted by recloser.
Time required by the recloser to reset back to reset shot
count.
Time required for unlock and reset the self-reclosing
module during lockout state. The unlock operation is carry
out when no operators attended the relay during lockout
state.
When the number of self-reclosing operations match the
number of shots setting, further fault trip will perform the
lockout
Relay lockout when the tripping is initiated by the
persistent fault.
