Control
MODEINT
The auto reclosing mode is selected with the
the mode can be selected by connecting an integer, for example from function block B16I, to
MODEINT input. The six possible modes are described in table 6 with their corresponding
the
MODEINT integer value. When a valid integer is connected to the input MODEINT 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
ON and OFF
These inputs can be connected to binary inputs or to a communication interface block for
external control.
PLCLOST
This is intended for line protection permissive signal channel lost (fail) for example, PLC=
Power Line Carrier failure. It can be connected, when it is required to prolong the auto
reclosing dead time when communication is not working, that is, one line end might trip with a
zone2 delay. If this is used the auto recloser must also be started from zone2 time delayed trip.
RESET
Used to reset the auto recloser to start conditions. Possible hold by thermal overload
protection will be reset. Circuit breaker position will be checked and time settings will be
restarted with their set times.
RSTCOUNT
There is a counter for each type of auto reclosing and one for the total number of circuit
breaker close commands issued. All counters are reset with the
IEC 61850 command.
SKIPHS
The high-speed auto reclosing sequence can be skipped and be replaced by normal auto
reclosing sequence by activating
activated. The replacement is done for the 1st shot.
START
START input should be connected to the trip function (SMPPTRC) output, which starts the
The
auto recloser for 1/2/3-phase operation. It can also be connected to a binary input for start
from an external contact. A logical OR-gate can be used to combine the number of start
sources.
STARTHS, Start high-speed auto reclosing
It may be used when one wants to use two different dead times in different protection trip
operations. This input starts the dead time
this input is without a synchronization check.
SYNC
This input is connected to the internal synchrocheck function when required or to an external
device for synchronism. If neither internal nor external synchronism or energizing check is
required, it can be connected to a permanently high source, TRUE. The signal is required for
three-phase shots 1-5 to proceed (Note! Not the high-speed step).
