Functionality

The protection relay supports six setting groups. Each setting group contains parameters
categorized as group settings inside application functions. The customer can change the
active setting group at run time.
The active setting group can be changed by a parameter or via binary inputs depending on
the mode selected with the Configuration/Setting Group/SG operation mode setting.
The default value of all inputs is FALSE, which makes it possible to use only the required
number of inputs and leave the rest disconnected. The setting group selection is not
dependent on the SG_x_ACT outputs.
Table 36: Optional operation modes for setting group selection
SG operation mode
Operator (Default)
Logic mode 1
Logic mode 2
For example, six setting groups can be controlled with three binary inputs. The SG
operation mode is set to "Logic mode 2" and inputs BI_SG_2 and BI_SG_5 are
connected together the same way as inputs BI_SG_3 and BI_SG_6.

Description
Setting group can be changed with the setting
Settings/Setting group/Active group.
Setting group can be changed with binary inputs
(BI_SG_2...BI_SG_6). The highest TRUE binary
input defines the active setting group.
Setting group can be changed with binary inputs
where BI_SG_4 is used for selecting setting groups
1-3 or 4-6.
When binary input BI_SG_4 is FALSE, setting
groups 1-3 are selected with binary inputs BI_SG_2
and BI_SG_3. When binary input BI_SG_4 is TRUE,
setting groups 4-6 are selected with binary inputs
BI_SG_5 and BI_SG_6.
