Activation of setting group
Basic
REx 5xx protection, monitoring and control terminals have four built-in
independent groups (sets) of setting parameters, which can be activated at
any time on five different ways:
1. Locally by means of built-in man-machine interface (MMI)
2. Locally by means of front-connected personal computer (PC)
3. Remotely through the Station Monitoring System (SMS), when
remote communication option is built into the terminal.
4. Remotely through the Station Control System (SCS), when remote
communication option is built into the terminal.
5. Locally by means of up to four, programmable binary inputs.
In Local man-machine communication (1MRK 580 156-XEN) the proce-
dure is described, necessary for changing the active setting group by the
built-in MMI. Operating procedures for the PC aided methods of chang-
ing the active setting groups are described in the corresponding SMS doc-
uments and instructions for the operators within the SCS documents. This
document deals with the option to change the active setting group by
means of the control signals connected to the programmable binary inputs
of a terminal.
Different conditions in networks of different voltage levels require high
adaptability of the used protection and control schemes, to best provide
for dependability, security, and selectivity requirements. Protection
schemes especially operate with higher degree of availability, if the set-
ting values of their parameters are continuously optimised regarding the
conditions in power system.
The operational departments can plan different operating conditions for
the primary equipment. The protection engineer can prepare in advance
for the necessary optimised and pre-tested settings for different protection
functions. Four different groups of setting parameters are available in
REx 5xx terminals. Any of them can be activated automatically through
up to four different programmable binary inputs by means of external
control signals.
This function has four built-in input signals, as shown on Fig. 1. Each is
configurable to any of the binary inputs built into the terminal. Configura-
tion must be performed under the menu:

The number of the signals configured must correspond to the number of
the setting groups to be controlled by the external signals (contacts).
