6. Control

RET620 integrates functionality for the control of circuit
breakers, disconnectors and earth switches via the front
panel HMI or by means of remote controls. The IED includes
two circuit breaker control blocks. In addition to the circuit
breaker control, the IED features four disconnector control
blocks intended for the motor-operated control of
disconnectors or circuit breaker truck. Furthermore, the IED
offers two control blocks intended for the motor-operated
control of earthing switch. On top of that, the IED includes
additional four disconnector position indication blocks and
two earth switch position indication blocks usable with
manually-only controlled disconnectors and earth switches.
Two physical binary inputs and two physical binary outputs
are needed in the IED for each controllable primary device
taken into use. Depending on the chosen hardware
configuration of the IED, the number of binary inputs and
binary outputs varies. In case the amount of available binary
inputs or outputs of the chosen hardware configuration is not

sufficient, connecting an external input or output module, for
example RIO600, to the IED can extend binary inputs and
outputs utilizable in the IED configuration. The binary inputs
and outputs of the external I/O module can be used for the
less time-critical binary signals of the application. The
integration enables releasing of some initially reserved binary
inputs and outputs of the IED.
The suitability of the binary outputs of the IED which have
been selected for the controlling of primary devices should be
carefully verified, for example, the make and carry as well as
the breaking capacity. 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 graphical LCD of the IED's HMI includes a single-line
diagram (SLD) with position indication for the relevant primary
devices. Interlocking schemes required by the application are
configured using the Signal Matrix or the Application
Configuration tools in PCM600.
