The data for ten faults detected by overcurrent elements is stored under headings beginning with FAULT LOCATION 0. This
information cannot be cleared; data for new events is always stored as fault 0. The data for each previous fault is shifted to
the next highest number, and Event 9 is discarded.

The present shot number which the autoreclose scheme is using to control protection settings is displayed in the AR SHOT
NUMBER IN EFFECT value. If the scheme has reached Lockout, the display is the shot number after which a trip caused lock-
out. The
AR SHOTS REMAINING value displays the number of reclose shots that can still be performed. After this point, the
reclose system will be either reset or locked-out. The value displayed is contained in the Shot Limit memory. Each time a
reclose shot is performed, in a given sequence, this Shot Limit is reduced by one. The Shot Limit can also be reduced to
any given value less than the programmed value by the current supervision function.
The number of reclosures in the past hour is shown in the
AR SHOT RATE value. This value will be cleared by a RESET AR
RATE DATA
command via the front panel or communications.
The
AR SHOT COUNT value shows the total number of reclosures since the AR SHOT COUNT LAST RESET date.
