8.6.1 Auto reclosing
– OPTION
Auto reclosing (AR -
RECL
) means that a delayed switch-on is ordered after an initial
TRIP
has been issued
by any of the Overcurrent or Earth fault Protrol protection functions. This option can be acquired for one
bay only, or for all three bays.
Activation of the function can be made at the device using a binary input, or the ACN button. It can also be
ordered by the remote control centre. The ACN button must be pressed 5 s before toggling takes place.
Indication to and order from SCADA is configured as double point / double command, see
I/O-addressing/Binary inputs/Detector m/RECL OFF/ON
and
I/O-addressing/Binary outputs/Detector m/
RECL OFF/ON,
respectively. These objects are blocked from factory.
Visual indication of AR OFF/ON can be chosen as follows:
AR for Detector 1
–
outputs 1
–
8, however, always AUX-LED
AR for Detector 2 and 3
–
outputs 1
–
8, and/or AUX-LED
After reclosure the function is always OFF. Reactivation can be done from SCADA but will always be done
automatically by Acknowledge after a preset time or by pressing the ACN button. Also, a restart of the
device inactivates AR. Manual switch-on of the circuit breaker blocks auto reclosure for 60 s.
The event log shows events for AR OFF/ON, AR startad and AR executed:
RECL OFF

RECL ON

It is strongly recommended to use the Non-directional earth fault function with activation after switch-on
to ensure safe detection of a permanent earth fault after the auto reclosure operation.
