When the LOCKED output is active, the AR function is in lockout. This means that new sequences cannot be initialized, because AR is insensitive to initiation commands. It can be released from the lockout state in the following ways.
- The function is reset through communication with the RecRs parameter. The same functionality can also be found in the Clear menu (DARREC reset).
- The lockout is automatically reset after the reclaim time, if the Auto lockout reset setting is in use.
Note: If the Auto lockout reset setting is not in use, the lockout can be released only with the RecRs parameter.
The AR function can go to lockout for many reasons.
- The INHIBIT_RECL input is active.
- All shots have been executed and a new initiation is made (final trip).
- The time set with the Auto wait time parameter expires and the automatic sequence initiation is not allowed because of a synchronization failure.
- The time set with the Wait close time parameter expires, that is, the circuit breaker does not close or the automatic sequence initiation is not allowed due to a closing failure of the circuit breaker.
- A new shot is initiated during the discrimination time.
- The time set with the Max wait time parameter expires, that is, the master unit does not release the slave unit.
- The frequent operation counter limit is reached and new sequence is initiated. The lockout is released when the recovery timer elapses.
- The protection trip signal has been active longer than the time set with the Max wait time parameter since the shot initiation.
- The circuit breaker is closed manually during an autoreclosing sequence and the manual close mode is FALSE.
