Application manual
MODE
When a valid integer is connected to the MODEINT input, the selected ARMode setting
will be invalid and the MODEINT input value will be used instead. The selected mode
is reported as an integer on the MODE output. The six possible modes are described in
Table 32 with their corresponding MODEINT integer value.
PERMIT1P
Permit single-pole trip is the inverse of PREP3P. It can be connected to a binary output
relay 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-pole trip.
PREP3P
Prepare three-pole trip is usually connected to the trip block to force a coming trip to
be a three-pole one. If the auto recloser cannot make a single-pole or two-pole auto
reclosing, the tripping should be three-pole.
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 tUnsucCl, the SUCCL output is activated after the set time interval
tSuccessful.
SYNCFAIL
The SYNCFAIL output indicates that the auto recloser is inhibited because the
synchrocheck or 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 119.
