• QB9_OP = 1
• QB9_CL = 0
• QC9_OP = 1
• QC9_CL = 0
If, in this case, line voltage supervision is added, then rather than setting QB9 to
open state, specify the state of the voltage supervision:
• QB9_OP = VOLT_OFF
• QB9_CL = VOLT_ON
If there is no voltage supervision, then set the corresponding inputs as follows:
• VOLT_OFF = 1
• VOLT_ON = 0

SEMOD114927-4 v7
The logic rotating switch for function selection and LHMI presentation function
(SLGAPC) (or the selector switch function block, as it is also known) is used to get
a selector switch functionality similar with the one provided by a hardware multi-
position selector switch. Hardware selector switches are used extensively by
utilities, in order to have different functions operating on pre-set values. Hardware
switches are however sources for maintenance issues, lower system reliability and
extended purchase portfolio. The virtual selector switches eliminate all these
problems.
SLGAPC function block has two operating inputs (UP and DOWN), one blocking
input (BLOCK) and one operator position input (PSTO).
SLGAPC can be activated both from the local HMI and from external sources
(switches) via the IED binary inputs. It also allows the operation from remote (like
