Switch Function
SGF1/5 Latching function for the alarm signal of earth fault stage I
When SGF1/5=0, the alarm signal returns to its initial state, i.e. the
output relay drops off, when the signal causing the operation falls
below the starting level.
When SGF1/5=1, the alarm signal remains on, i.e. the output relay
remains operated although the measured signal falls below the
starting level.
Then the alarm signal of the earth fault stage I
pressing the RESET and PROGRAM push-buttons simultaneously
or using command V101. When the display is off the signals can also
be reset by pressing only the PROGRAM push button.
SGF1/6 Latching function for the alarm signal of unbalance stage ∆I>.
When SGF1/6=0, the alarm signal returns to its initial state, i.e. the
output relay drops off, when the signal causing the operation falls
below the starting level.
When SGF1/6=1, the alarm signal remains on, i.e. the output relay
remains operated although the measured signal falls below the
starting level.
Then the alarm signal of the unbalance stage ∆I> must be reset by
pressing the RESET and PROGRAM push-buttons simultaneously
or by using command V101. When the display is off the signals can
also be reset by pressing only the PROGRAM push button.
SGF1/7 The earth fault stage can be set out of operation by means of
this switch.
SGF1/8 The unbalance stage can be set out of operation by means of
this switch.
SGF2/1 Switches SGF2/1...3 are used for selecting the mode of operation
SGF2/2 of the start indicators of the different stages and the LEDs for the
SGF2/3 measured currents. When the switches are in position 0 the start
indicators are all automatically reset when the fault is cleared.
In order to get a hand reset start indication for the stages, their
respective switches have to be in position 1. When the switches are
in position 0 the LEDs for the measured currents are not affected by
a start, and when the switches are in position 1 it is possible to get
information of which phase activated a start.
When SGF2/1=1, the start indicator of the overcurrent stage I> has
to be manually reset.
When SGF2/2=1, the start indicator of the earth fault stage I
to be manually reset.
When SGF2/3=1, the start indicator of the unbalance stage ∆I> has
to be manually reset.
