Position change
The three binary inputs used for this must have sequential numbers, such as BI 1, BI
2, and BI 3.
User Defined Meas-
ured Values (MVU)
and Limit Values
(LVU)
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 5-15).
Figure 5-15
Information properties example for information type “Limit Value User Defined”
(LVU)
If, for example, a low current reporter should be established using the CFC logic, and
the percentage of the measured current should be matched to a certain amp value,
the following values are entered in window according to Figure 5-15:
The
'LPHQVLRQ
is A (amps). The
&RQYHUVLRQ)DFWRU
is 150: 150 A corresponds
to 100 % input current. The limit value upon start-up is set for 120 A.
Metered Values
For metered values, the determination of the polarity (+/–) is determined by the direc-
tion of power flow (Figure 5-16). The user may also define the units for pulsed metered
values (
309
), the conversion factor, and the number of significant digits following the
decimal point (Figure 5-16). If the event pulse option is selected, each individual im-
pulse 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 ex-
ample, 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.
