Technical Reference Manual
SGF1...SGF3
Switchgroups SGF1...SGF3 are used for configuring the desired function as follows:
Table 4.1.3.3-2 SGF1
Switch
Function
SGF1/1
Selection of the latching feature for output PO1.
SGF1/2
Selection of the latching feature for output PO2.
When the switch is in position 0 and the measuring signal
that caused an operation falls below the set start level, the
output contact returns to its initial state.
When the switch is in position 1, the output contact
remains active although the measuring signal that caused
an operation falls below the set start level.
The latching feature selected, the output contact is reset
with the push-button on the front panel, via the external
binary input or the serial bus.
SGF1/3
Minimum pulse length for signal outputs SO1 and SO2.
- 0 = 80 ms
- 1 = 40 ms
SGF1/4
Minimum pulse length for power outputs PO1 and PO2.
- 0 = 80 ms
- 1 = 40 ms
Note!
The latching function of PO1 and PO2 will overrun this
function.
SGF1/5
Circuit-breaker failure protection (CBFP).
When the switch is in position 1, the signal on output PO1
starts a timer which will generate a delayed signal to the
output PO2 if the fault is not cleared before the operate
time elapses.
When the switch is in position 0 the circuit-breaker failure
protection is out of operation.
SGF1/6
Not in use.
SGF1/7
Not in use.
SGF1/8
