12.2.3.1 Configuration
Use the PCM600 configuration tool to configure signals.
Auto recloser function parameters are set via the local HMI or Parameter Setting Tool (PST).
Parameter Setting Tool is a part of PCM600.
Recommendations for input signals
Please see Figure 134, Figure
examples.
BLKOFF
Used to unblock the auto recloser when it has been blocked due to activating
by an unsuccessful auto reclosing attempt if the
BLKON
Used to block the auto recloser, for example, when certain special service conditions arise.
When used, blocking must be reset with
CBCLOSED and CBREADY
These binary inputs should pick-up information from the circuit breaker. At three operating
gears in the circuit breaker (single pole operated circuit breakers) the connection should be
"All poles closed" (series connection of the NO contacts) or "At least one pole open" (parallel
connection of NC contacts). The
for an auto reclosing operation, either Close-Open (CO), or Open-Close-Open (OCO). If the
available signal is of type "circuit breaker not charged" or "not ready", an inverter can be
inserted in front of the
INHIBIT
To this input shall be connected signals that interrupt an auto reclosing cycle or prevent a start
from being accepted. Such signals can come from protection for a line connected shunt
reactor, from transfer trip receive, from back-up protection functions, busbar protection trip
or from breaker failure protection. When the circuit breaker open position is set to start the
auto recloser, then manual opening must also be connected here. The inhibit is often a
combination of signals from external IEDs via the I/O and internal functions. An OR-gate is
then used for the combination.
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

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
