Figure 11: Screen after a circuit breaker trip�
After an automatic reclosing sequence, the partial reclosing meters restart after 15
or 30 minutes after the last reclose, according to the value configured (see “
6.2.1.-
SDR: EARTH LEAKAGE RECLOSING SEQUENCE”
and
“6.2.2.- SRM: CIRCUIT BREAKER
RECLOSING SEQUENCE”
)
4�10�2�- AUTOMATIC RECLOSING IS NOT POSSIBLE
Automatic reclosing may not be possible for one of the following reasons:
1�- Reclosing has been disabled when programming the device. The display will show the cause
of the trip without the REC symbol.
The reset is only possible by modifying the Configuration of the device, see
“6.2.1.- SDR: EARTH
LEAKAGE RECLOSING SEQUENCE”
AND
“6.2.2.- SRM: CIRCUIT BREAKER RECLOSING SEQUENCE”
2�- The number of reclosing attempts has been exhausted. The display will show the cause of
the trip without the REC symbol.
In this case, the reset is only possible by pressing the
RESET
key or by an external order of the
EXT input.
Reclosing the device with the
RESET
key or the
EXT
input restarts the partial reclosing meters.
3�- The device was tripped manually by pressing the TEST key. The display will show the “ TEST ”
text, see
“5.2.3.- TRIPPING WITH THE TEST KEY”
�
In this case, the reset is only possible by pressing the TEST key again.
4�- The trip was caused by the EXT remote control input. The display will show the “ EXT ” text,
see
“5.2.4.- TRIP DUE TO EXT ON/OFF INPUT”
In this case, reclosing is only possible with another external order of the
EXT
remote control
input.
