Figure 153: Configurable operating sectors
Table 295: Momentary per phase direction value for monitored data view
Criterion for per phase direction information The value for DIR_A/_B/_C
The ANGLE_X is not in any of the defined sectors, or the direc-
tion cannot be defined due too low amplitude
0 = unknown
The ANGLE_X is in the forward sector 1 = forward
The ANGLE_X is in the reverse sector 2 = backward
The ANGLE_X is in both forward and reverse sectors, that is,
when the sectors are overlapping
3 = both
Table 296: Momentary phase combined direction value for monitored data view
Criterion for phase combined direction information The value for DIRECTION
The direction information (DIR_X) for all phases is unknown 0 = unknown
The direction information (DIR_X) for at least one phase is
forward, none being in reverse
1 = forward
The direction information (DIR_X) for at least one phase is
reverse, none being in forward
2 = backward
The direction information (DIR_X) for some phase is forward
and for some phase is reverse
3 = both
FAULT_DIR gives the detected direction of the fault during fault situations, that is,
when the START output is active.
