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.

SG operation mode
Description
Operator (Default)
Setting group can be changed with the setting Settings > Setting
group > Active group.
Value of the
SG_LOGIC_SEL
output is FALSE.
Logic mode 1
Setting group can be changed with binary inputs
(
BI_SG_2...BI_SG_6
). The highest
TRUE
binary input defines the
active setting group.
Value of the
SG_LOGIC_SEL
output is TRUE.
Logic mode 2
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 selec-
ted 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
.
Value of the
SG_LOGIC_SEL
output is TRUE.
The setting group (SG) is changed whenever switching the
SG operation
mode setting from "Operator" to either "Logic mode 1" or "Logic mode 2."
Thus, it is recommended to select the preferred operation mode at the
