Switch Function
SGF2/1 Switches SGF2/1...4 are used for selecting the operation characteristic of the start
SGF2/2 indicators of the different stages. When the switches are in position 0 the start signals
SGF2/3 are all automatically reset when the fault is cleared. To give the indicator of a stage the
SGF2/4 hand reset mode of operation, the corresponding switch is set in position 1:
SGF2/1 = 1 equals manual reset mode for the start indication of stage I>
SGF2/2 = 1 equals manual reset mode for the start indication of stage I>>
SGF2/3 = 1 equals manual reset mode for the start indication of stage I
0
>
SGF2/4 = 1 equals manual reset mode for the start indication of stage I
0
>>
SGF2/5 Operation of the high-set phase overcurrent stage I>>.
When SGF2/5 = 0 the high-set stage I>> is alerted
When SGF2/5 = 1 the high-set stage I>> is out of operation and the display shows
"- - -"
SGF2/6 Operation of the high-set earth-fault stage I
0
>>.
When SGF2/6 = 0 the high-set stage I
0
>> is alerted
When SGF2/6 = 1 the high-set stage I
0
>> is out of operation and the display shows
"- - -"
SGF2/7 Start signal of the high-set stage I>> to the auto-reclose signal output AR1.
When SGF2/7 = 1, the start signal of the I>> stage is routed to output AR1.
Note! Outputs AR1 and SS3 are interconnected and they always carry the same signal.
Therefore, if AR1 is used for starting auto-reclose functions, SS3 cannot be used for
any other purpose.
When SGF2/7 =0, the start signal of the I>> stage is not routed to output AR1 nor
SS3. Thus the signal output SS3 is available for other purposes.
SGF2/8 Start signal of the low-set stage I
0
> or high-set stage I
0
>> to auto-reclose signal output
AR3.
When SGF2/8 = 0 the start signal from the I
0
> stage is routed to output AR3
When SGF2/8 = 1 the start signal from the I
0
>> stage is routed to output AR3
When the relay is delivered from the factory the
SGF2 switches are set at zero, i.e. the checksum
for SGF2 is 0.
