Table 30: Optional operation modes for setting group selection
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 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
.
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 time
of installation and commissioning and not change it throughout the
protection relay's service. Changing the
SG operation mode setting from
"Logic mode 1" to "Logic mode 2" or from "Logic mode 2" to "Logic
mode 1" does not affect the setting group (SG).
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
.
