If the auto-reclose function has generated the definite trip alarm signal, the text
DEF. TRIP ALARM will appear on the display to indicate that the CB has been
left in the open position and that no more auto-reclosures are being generated.
If a pickup or trip target for the element that initiated an ongoing auto-reclose shot
is cleared, the text Shot Due will appear on the display to indicate that a shot is
ongoing and that the CB will be closed after expiration of the dead time.
In case the CB reclosing failed or it is disabled, this will be indicated on the display
with the text RECLOSING FAILED.
If the auto-reclose function has generated the lockout signal, the text LOCKOUT will
appear on the display to indicate that the whole auto-reclose function is temporarily
disabled.
