COUNTAR
Indicates the total number of auto reclosing shots made.
INHIBOUT
INHIBIT input is activated it is reported on the INHIBOUT output.
If the
INPROGR
Indicates that an auto recloser sequence is in progress, from start until circuit breaker close
command.
MODE
When a valid integer is connected to the
invalid and the
integer on the
corresponding
PERMIT1P
Permit single-phase trip is the inverse of
for connection to external protection or trip relays. In case of a total loss of auxiliary power,
the output relay drops and does not allow single-phase trip.
PREP3P
Prepare three-phase trip is usually connected to the trip block to force a coming trip to be a
three-phase one. If the auto recloser cannot make a single-phase or two-phase auto reclosing,
the tripping should be three-phase.
READY
Indicates that the auto recloser is ready for a new and complete auto reclosing sequence. It
can be connected to the zone extension if a line protection should have extended zone reach
before auto reclosing.
SETON
Indicates that auto recloser is switched on and operative.
SUCCL
If the circuit breaker closing command is given and the circuit breaker is closed within the set
time interval
SYNCFAIL
SYNCFAIL output indicates that the auto recloser is inhibited because the synchrocheck or
The
energizing check condition has not been fulfilled within the set time interval, tSync. Also
ABORTED output will be activated.
UNSUCCL
Indicates unsuccessful reclosing.
WFMASTER
Wait from master is used in high priority units to hold back auto reclosing of the low priority
unit during sequential auto reclosing. Refer to the recommendation for multi-breaker
arrangements in Figure 136.
Busbar protection REB670

MODEINT input value will be used instead. The selected mode is reported as an
MODE output. The six possible modes are described in Table
MODEINT integer value.
tUnsucCl , the SUCCL output is activated after the set time interval tSuccessful .
MODEINT input, the selected ARMode setting will be
