WAIT
Used to hold back reclosing of the “low priority unit” during sequential auto reclosing. See
“Recommendation for multi-breaker arrangement” below. The signal is activated from
output WFMASTER on the second breaker auto recloser in multi-breaker arrangements.
ZONESTEP
The ZONESTEP input is used when coordination between local auto reclosers and down
stream auto reclosers is needed. When this input is activated the auto recloser increases its
actual shot number by one and enters “reclaim time” status. If a start is received during this
reclaim time the auto recloser is proceeding as usual but with the dead time for the
increased shot number. Every new increase of the shot number needs a new activation of
the ZONESTEP input. This functionality is controlled by the setting ZoneSeqCoord.
Recommendations for output signals
Please see Figure 311, Figure 312 and Figure 313 and default factory configuration for
examples.
1PT1 and 2PT1
Indicates that single-pole or two-pole auto reclosing is in progress. It is used to
temporarily block an ground-fault and/or pole disagreement function during the single-
pole or two-pole open interval.
3PT1, 3PT2, 3PT3, 3PT4 and 3PT5
Indicates that three-pole auto reclosing shots one to five are in progress. The signals can
be used as an indication of progress or for own logic.
ABORTED
The ABORTED output indicates that the auto recloser is inhibited while it is in one of the
following internal states:
• inProgress: auto recloser is started and dead time is in progress
• reclaimTimeStarted: the circuit breaker closing command has started the reclaim
timer
• wait: an auto recloser, acting as slave, is waiting for a release from the master to
proceed with its own reclosing sequence
ACTIVE
Indicates that the auto recloser is active, from start until end of reset time.
BLOCKED
Indicates that auto recloser is temporarily or permanently blocked.
