SGF1

Switch Function
SGF1/1 Selection of the latching feature for PO1
SGF1/2 Selection of the latching feature for PO2
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.
SGF1/4 Minimum pulse length for SO1 and SO2 and optional SO3, SO4 and SO5
0 = 80 ms
*
1 = 40 ms
*
SGF1/5 Minimum pulse length for PO1, PO2 and PO3
0 = 80 ms
*
1 = 40 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
SGF1/7 Trip lockout function
0 = the trip lockout function is not in use. PO3 works as a normal power output relay.
*
1 = the trip lockout function is in use. PO3 is dedicated to this function.
*
SGF1/8 External fault warning
When the switch is in position 1, the warning signal from the trip-circuit supervision or
*
generated in case of continuous light on light sensor inputs is routed to SO2.

SGF2

Switch Function
SGF2/1 Operation mode of the pickup target of element 51P
SGF2/2 Operation mode of the pickup target of element 50P-1
SGF2/3 Operation mode of the pickup target of element 50P-2
SGF2/4 Operation mode of the pickup target of element 51N
SGF2/5 Operation mode of the pickup target of element 50N
SGF2/6 Operation mode of the trip target of element 46
SGF2/7 Operation mode of the alarm target of element 49
0 = the pickup target is automatically cleared after the fault has disappeared
*
1 = latching. The pickup target remains active although the fault has disappeared.
