RESET CIRCUIT BREAKER LOCKOUT

Lockout conditions caused by the circuit breaker condition monitoring functions can be reset according to the
condition of the Rst CB mon LO by setting found in the CB CONTROL column. There are two options; CB Close
and User interface.
If set to CB Close, a timer setting, CB mon LO RstDly, becomes visible. When the circuit breaker closes, the CB
mon LO RstDly time starts. The lockout is reset when the timer expires.
If set to User Interface then a command, CB mon LO reset, becomes visible. This command can be used to
reset the lockout from a user interface.
An Autoreclose lockout generates an Autoreclose lockout alarm. Autoreclose lockout conditions can be reset by
various commands and setting options found under the CB CONTROL column.
