Configuration
switches
The switches SGF1...7, SGB1...6 and SGR1...9
are used for selecting additional functions re-
quired for a specific application. The numbers
of the switches, 1…8, and the positions, 0 and
1, are indicated on the display during the set-
ting procedure. In normal service, only the
checksums of the switchgroups are indicated on
the display. The checksums are found in the
main menu of the relay modules, see "Menu
chart". The tables also show the factory settings
of the switches and the checksum ∑ of the fac-
tory setting. The calculation of the checksum is
described in the end of this paragraph.

SGF1...4/1 Frequency function alone is used 1
SGF1...4/2 Both frequency and df/dt function in use 0
SGF1...4/3 The df/dt function alone is used 0
SGF1...4/4 Operation mode for the start indicating codes of the separate 0
protection stages.
When the switch is in position 0, the start indicating operation
code is automatically reset when the fault disappears.
When the switch is in position 1, the code remains lit, even
though the fault disappears.

Switchgroup SGF5
(modified 97-01)
The switches of switchgroup SGF5 are used for
selecting the operation mode of the output sig-
nals SS1...SS4 and TS1...TS4. When the switch
is in the position 1, a control signal is continu-
ously applied to the output. This means that
the output is active as long as the stage that con-
trols it is active. When, on the other hand, the
switch is in position 0, the output is active only
as long as the preset pulse is present. When the
pulse disappears, the output resets, even though
the stage that controls it remains active.
