CHAPTER 5: STATUS AUTORECLOSE
850 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 5–17
Autoreclose
Path: Status > Autoreclose 1(X)
The present shot number which the Autoreclose scheme is using is displayed in the SHOT
NUMBER IN EFFECT value. If the scheme has reached Lockout, the display is the shot
number after which a Trip caused Lockout.
The SHOTS REMAINING value displays the number of reclose shots that can still be
performed. 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 or by user setting (AR1 Reduce Maximum to 1, 2 or 3).
The number of reclosures in the past hour is shown in the SHOT RATE PER HOUR value. The
TOTAL SHOT COUNT value shows the total number of reclosures since the SHOT CNT LAST
RST D/T.
It must be noted that the TOTAL SHOT COUNT and SHOT CNT LAST RST D/T are stored in
non-volatile memory, which can be restored after reboot. All statuses can be cleared by
the command in RECORDS \CLEAR RECORDS \AUTORECLOSE 1.
