5.12.2.1 MENU CONTROL OF INDIVIDUAL PHASE.
To independently adjust voltage/current phase angles:
1. Under menu control in the SETTINGS MODES PHASE INDIVIDUAL-ADJ-MODE ENABLE menu,
select either “Individual-voltage” or “Individual-current” phase adjust mode. The difference between
these two selections will be explained in 5.12.2.2. The two are equivalent under menu control.
2. Next, enter the SETTINGS MODES PHASE INDIVIDUAL-ADJ-MODE ADJUST menu. Then select
the desired state in which you wish to change the phase (PREFAULT, FAULT or POSTFAULT).
After this step, the menus will vary depending on the current mode.
5.12.2.1.1 Individual phase adjustment in I1-LOW & I1-HIGH current modes
In these current modes, after PREFAULT, FAULT or POSTFAULT is selected, a display, similar to the one
below, will appear, showing the present settings for that particular fault state.
Note that these numbers are settings--and not actual measured values--in contrast to the [VALUE
DISPLAY]. In addition, these are absolute values, not relative values as shown on the [VALUE DISPLAY].
To change a particular setting, turn the [MODIFY] knob to move the cursor to the desired quantity. Press
[SELECT], and the cursor will move to the first digit of the phase value to be modified. An example is
shown below for VB.
Turn [MODIFY] knob to the desired value, and then press [SELECT]. The cursor will move back to the first
letter of the quantity, as in the example displayed below:
Repeat this, as desired, for all phases, and for each of the prefault, fault and postfault states.
The individual phase adjustment menu tree for I1-LOW and I1-HIGH current modes is summarized in the
following figure:
