Fig. 5.1.4.12.-1 An example of calculating the checksum of a SG_ selector switchgroup
When the checksum, calculated according to the example above, equals the
checksum of the relay, the switches in the switchgroup have been properly set.
The factory default settings of the switches and the corresponding checksums are
presented in the tables below.
SGF1...SGF5
Switchgroups SGF1...SGF5 are used for configuring the desired function as follows:
Table 5.1.4.12.-2 SGF1
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 0
*
When the switch is in position 0 and the measuring signal
which caused the trip falls below the set pickup 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 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 0
*
0=80 ms
