Technical Reference Manual
SGF1...SGF5
Switchgroups SGF1...SGF5 are used for configuring the desired function as follows:
Table 4.1.4.10-2 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 start value, the output
contact will return to its initial state.
• When the switch is in position 1, the output contact will remain
active although the measuring signal which caused the trip
falls below the set start 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
Note!
The latching feature being selected for PO1, PO2 and PO3 will
override this function.
SGF1/6 CBFP
• 0 = CBFP is not in use
• 1 = the signal to PO1 will start a timer which will generate a
delayed signal to PO2, provided that the fault is not cleared
before the CBFP operate time has elapsed.
SGF1/7 Trip lockout function
• 0 = the trip lockout function is not in use.
• 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.
