Switch Function Default setting
SGF1/1 Selection of the latching feature for PO1 0
SGF1/2 Selection of the latching feature for PO2 0
SGF1/3 Selection of the latching feature for PO3
*
When the switch is in position 0 and the measuring signal which caused the trip falls below
the set pickup value, the output contact returns to its initial state.
*
When the switch is in position 1, the output contact remains active although the measuring
signal which caused the trip falls below the set pickup value.
A latched output contact can be unlatched either via the HMI, a digital input or the serial bus.
0
SGF1/4 Minimum pulse length for SO1 and SO2 and optional SO3, SO4 and SO5
*
0 = 80 ms
*
1 = 40 ms
0
SGF1/5 Minimum pulse length for PO1, PO2 and PO3
*
0 = 80 ms

SGF1/6
CBFAIL
*
0 = CBFAIL is not in use

1 = the signal to PO1 pickups a timer which generates a delayed signal to PO2, provided that
the fault is not cleared before the CBFAIL operate time has elapsed
0
SGF1/7 Trip lockout function
*
0 = the trip lockout function is not in use. PO3 works as a normal power output relay.
