Table 5.1.4.7.-5 SGF4 (Continued)
Switch Function
SGF4/7 Start and trip criteria for element 27P-1
0 = element operates when one of the phase-to-phase voltages falls below the set pickup
*
value.
1 = element operates when all the phase-to-phase voltages fall below the set value.
*
SGF4/8 Start and trip criteria for element 27P-2
0 = element operates when one of the phase-to-phase voltages falls below the set pickup
*
value.
1 = element operates when all the phase-to-phase voltages fall below the set value.
*
SGF4/9 27P-1 Alarm mode selection
0 = normal operation of element 27P-1, used for tripping purposes
*
1 = element 27P-1 operates as 27P-1 Alarm.
*
The alarm signal is routed to element 27P-1 trip in relay matrix, and the pickup signal of
element 27P-1 is inhibited. When the alarm signal is active, the pickup LED is lit.
SGF4/10 Internal blocking of pickup and trip of element 47 when one of the measured phase-to-phase
voltages falls below 0.15 × U
0 = internal blocking of pickup and trip of element 47
*
1 = no internal blocking of pickup and trip of element 47
*
ΣSGF4
a)
If the switch SGF4/1 is set to 1, the switches SGF4/5...8 are overridden. Thereby all the elements use only phaseU
other phases are not checked or used.

Switch Function
SGF5/1 Selection of the latching feature for programmable LED1
SGF5/2 Selection of the latching feature for programmable LED2
SGF5/3 Selection of the latching feature for programmable LED3
SGF5/4 Selection of the latching feature for programmable LED4
SGF5/5 Selection of the latching feature for programmable LED5
SGF5/6 Selection of the latching feature for programmable LED6
SGF5/7 Selection of the latching feature for programmable LED7
SGF5/8
Selection of the latching feature for programmable LED8
When the switch is in position 0 and the signal routed to the LED is reset, the programmable
*
LED is cleared.
When the switch is in position 1, the programmable LED remains lit although the signal
*
routed to the LED is reset.
A latched programmable LED can be cleared either via the HMI, a digital input or the serial bus.
