Recommendations for output signals
Please see figure
SETON
Indicates that Autorecloser for 1/2/3-phase operation (SMBRREC) function is switched on and
operative.
BLOCKED
Indicates that SMRREC function is temporarily or permanently blocked.
ACTIVE
Indicates that SMBRREC is active, from start until end of Reclaim time.
INPROGR
Indicates that a sequence is in progress, from start until reclosing command.
UNSUCCL
Indicates unsuccessful reclosing.
CLOSECB
Connect to a binary output for circuit-breaker closing command.
READY
Indicates that SMBRREC function is ready for a new and complete reclosing sequence. It can be
connected to the zone extension if a line protection should extended zone reach before
automatic reclosing.
1PT1 and 2PT1
Indicates that single-phase or two-phase automatic reclosing is in progress. It is used to
temporarily block an earth-fault and/or pole disagreement function during the single-phase or
two-phase open interval.
3PT1, 3PT2, 3PT3, 3PT4 and 3PT5
Indicates that three-phase automatic reclosing shots 1-5 are in progress. The signals can be
used as an indication of progress or for own logic.
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 function cannot make a single-phase or two-phase reclosing, the
tripping should be three-phase.
PERMIT1P
Permit single-phase 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-phase trip.
Other outputs
The other outputs can be connected for indication, disturbance recording, as required.
