Additional functions required by individual applications are selected by means of the switchgroups SGF, SGB
and SGR indicated on the front panel. The numbering of the switches, 1...8, and the switch positions 0 and
1 are indicated when setting the switchgroups. In normal service only the checksums are shown. The
switchgroups SGF2, SGR2 and SGR3 are found in the submenus of the switchgroups SGF and SGR.
Functional switchgroups SGF1 and SGF2
Switch Function
SGF1/1 Switches SGF1/1...3 are used for selecting the operation characteristic of the low-set
SGF1/2 overcurrent stage I>, i.e. definite time mode of operation or inverse definite minimum time
SGF1/3 (I.D.M.T.) mode of operation. At inverse definite minimum time mode of operation the
switches are, further, used for selecting the current/time characteristic of the module.
SGF1/1 - 2 - 3 Mode of operation Characteristics
0 0 0 Definite time 0.05...300 s
1 0 0 I.D.M.T Extremely inverse
0 1 0 " Very inverse
1 1 0 " Normal inverse
0 0 1 " Long-time inverse
1 0 1 " RI-characteristic
0 1 1 " RXIDG-characteristic
1 1 1 " Not in use (long-time inverse)
SGF1/4 Selection of the circuit breaker failure protection.
When SGF1/4 =1 the trip signal TS2 will start a timer which will produce a
0.1…1 s delayed trip signal via TS1, if the fault has not been cleared before.
With switch SGF1/4 = 0 only the normal trip signal TS2 is activated.
SGF1/5 Selection of automatic doubling of the setting value of the
high-set overcurrent stage when the protected object
is energized.
When SGF1/5 = 0, no doubling of the setting value I>> is obtained.
When SGF1/5 = 1, the setting value of the I>> stage doubles automatically.
This makes it possible to give the high-set current stage a setting value below the
connection inrush current level.
SGF1/6 High-set stage of the earth-fault protection inhibited by starting of the low-set stage of
the overcurrent unit
When SGF1/6 = 0, the operation of the high-set earth-fault protection is operating under all
phase current conditions
When SGF1/6 =1, the earth-fault protection is inhibited if the low-set stage of the overcurrent
unit has started
