COMMENTS ON SETTINGS:
The factory default HMI password to change any setting is 1. See chapter 8 for details.
The ACTIVE GROUP setting, in the Advanced General Settings, selects which of the two settings groups is active at a
given time. Its default value is 1 (GROUP 1).
The procedure to set the Phase and Ground TOC (Time Delayed Overcurrent) functions (51P / 51N) is the same for both
functions: First, the pickup value must be set (PICKUP); Then, using the CURVE TYPE (current versus time tripping
characteristic curve), the type of time delay preferred is selected, either DEFINITE TIME, or any of the three inverse curves;
If the choice is any of the inverse curves (Inverse, Very Inverse or Extremely Inverse), then the relay takes into account the
TIME DIAL setting, to identify which of the curves in the family must be used (there are 195 different curves for each curve
type, depending on the Time Dial Selected); if the curve type selected is DEFINITE TIME, then the Time Dial setting is
ignored and the time delay used is the one specified in DEFINITE TIME setting.
