3.6. Other configuration settings
Only accessible by keyboard/display, on “CHANGE
SETTINGS”, “PROG. TABLE 0”, “DEFINE PROTECT.”. They are the
following:
3.6.1. Frequency
It can be 50 Hz or 60 Hz. It is a fundamental protection
setting. If it is not the correct one, the measurements and,
therefore, the protection operation will be wrong.
3.6.2. Language
It can be English or Spanish. It relates to the texts shown
ondisplay.
3.6.3. Phase order
It can be A, B, C or C, B, A. It aects only to the protection
functions of broken conductor and unbalance (currents and
voltages). To verify that the order corresponds to the wiring,
check in “measurements” that the ratio of the inverse/direct
component is close to 0 %, when introducing 3 balanced
currents of about 1 A.
3.6.4. Neutral Parameter
If it is “by transformer” indicates that an input transformer
exists to measure the zero sequence voltage; if it is “measured”
indicates that it must be calculated as a vectorial sum of the
simple phase to ground voltages.
3.6.5. Calibration
This menu position is exclusively to be used by the
Ormazabal's technical-commercial department, according
to a certain procedure. It should not be used by the user.
3.6.6. Test mode
The test mode is to be used by Ormazabal’s technical–
commercial department exclusively, following a specic
procedure. It must not be used by the user.
