6. Control
REF615 integrates functionality for the control of a
circuit breaker via the front panel HMI or by means
of remote controls. In addition to the circuit
breaker control the relay features two control
blocks which are intended for motor-operated con-
trol of disconnectors or circuit breaker truck and
for their position indications. Further, the relay of-
fers one control block which is intended for mo-
tor-operated control of one earthing switch control
and its position indication.
Two physical binary inputs and two physical binary
outputs are needed in the relay for each controlla-
ble primary device taken into use. Depending on
the chosen standard configuration of the relay the
number of unused binary inputs and binary outputs
varies. Further, some standard configurations also
offer optional hardware modules that increase the
number of available binary inputs and outputs.
If the amount of available binary inputs or outputs
of the chosen standard configuration is not suffi-
cient, the standard configuration can be modified
to release some binary inputs or outputs which
have originally been configured for other purposes,
when applicable, or an external input or output
module, for example, RIO600 can be integrated to
the relay. The binary inputs and outputs of the ex-
-
ical binary signals of the application. The integra-
tion enables releasing of some initially reserved
binary inputs and outputs of the relay in the stan-
dard configuration.
The suitability of the relay's binary outputs which
have been selected for controlling of primary de-
vices should be carefully verified, for example, the
make and carry as well as the breaking capacity
should be considered. In case the requirements for
the control-circuit of the primary device are not
met, the use of external auxiliary relays should be
considered.
The large graphical LCD of the relay's local HMI in-
cludes a single-line diagram (SLD) with position in-
dication for the relevant primary devices. Interlock-
ing schemes required by the application are
configured using the signal matrix or the applica-
tion configuration functionality of PCM600. De-
pending on the standard configuration, the relay
also incorporates a synchrocheck function to en-
sure that the voltage, phase angle and frequency on
either side of an open circuit breaker satisfy the
conditions for safe interconnection of two net-
works.
