The three binary inputs used for this must have sequential numbers, such as BI 1, BI
2, and BI 3.
For the information type "Measured Values User Defined" (098), the units, the conver-
sion factor, and the number of significant digits following the decimal point may be
specified. For the information type "Limit Values User Defined" (/98), a limit value may
be programmed (Figure 5-19).

The correlation between input current and a measured magnitude can be set as fol-
lows:
If, for example, a under current set point should be established using the CFC logic,
and the percentage of the measured current should be matched to a certain amp val-
ue, the following values are entered in window according to Figure 5-19:
The Dimension is A (amps). The Conversion Factor is 150: 150 A corresponds to
100 % input current. The limit value upon startup is set for 120 A.
For metered values, the determination of the polarity (+/–) is determined by the direc-
tion of power flow (Figures 5-20 and 5-21). The user may also define the transfer of
metered values from measured values (0909) (Figure 5-20), the units for pulsed me-
tered values (309), the conversion factor, and the number of significant digits following
the decimal point (Figure 5-21). If the event pulse option is selected, each individual
impulse increases the counter by one. If the double current pulse option is selected,
then each individual transition (positive or negative) increases the counter by one. If,
for example, MVARh is entered as the units and 1000 is entered as the conversion
factor, then 1000 impulses will result in a reading of one MVARh.
