Setting Notes

To enter these group-specific general protection data (P.System Data 2), select in
General
the SETTINGS menu theGroup A (Parameter group A), and in it P.System Data
2. The other setting group is accessible under Group B.
At addresses 1101 U PRIMARY OP. and 1102 I PRIMARY OP., the primary refer-
Rated Values of the
System ence voltage and reference current of the protected motor is entered. These values
are important for pickup settings. The allow the device to calculate operational values
as percentage values. For example, if a CT ratio of 500/1 is selected and the rated
current of the generator is 483 A, a value of 500 A should be entered at address 211
and a value of 483 A under I PRIMARY OP.. 483 amps are now displayed as 100%
in the percentage metering display.
Address 1108 ACTIVE POWER is used to specify the active power direction in the
Active Power Direc-
tion normal mode (Generator = output or Motor = input) or to adapt it to the power
system conditions without device recabling.
