Table 5.1.4.7.-5 SGF4 (Continued)
Switch Function
SGF4/7 Start and trip criteria for stage U<
0 = stage operates when one of the phase-to-phase voltages falls below the set start value.
*
1 = stage operates when all the phase-to-phase voltages fall below the set value.
*
SGF4/8 Start and trip criteria for stage U<<
0 = stage operates when one of the phase-to-phase voltages falls below the set start value.
*
1 = stage operates when all the phase-to-phase voltages fall below the set value.
*
SGF4/9 U< Alarm mode selection
0 = normal operation of stage U<, used for tripping purposes
*
1 = stage U< operates as U< Alarm.
*
The alarm signal is routed to stage U trip in relay matrix, and the start signal of stage U< is
inhibited. When the alarm signal is active, the start LED is lit.
SGF4/10 Internal blocking of start and trip of stage U
voltages falls below 0.15 × U
0 = internal blocking of start and trip of stage U
*
1 = no internal blocking of start and trip of stage U
*
ΣSGF4
a)
If the switch SGF4/1 is set to 1, the switches SGF4/5...8 are overridden. Thereby all the stages use only phase U
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.
