4.3.2.1 GENERAL SETTINGS
General settings describe and activate the electric system settings where the relay is going to operate. Some of these
settings will be used with measure values presentation purposes; however, some of them are directly applied during the
sampling and analogical-numerical conversion process (nominal frequency setting). Therefore, these settings need to be
altered so they fit with the system settings.
4.3.2.2 GROUP 1- GROUP 2 FUNCTION SETTINGS
The M family relays provide two independent setting groups. Group 1 is available in the Main Settings group, while Group
2 can be accessed in the Advanced Settings group. The setting groups can be selected by digital input, through a
communications command or from the EnerVista MII SETUP, or simply selecting it with the relay keypad. The setting that
shows the active group can be found in General Advanced Settings.
4.3.3.1 ADVANCED GENERAL SETTINGS
Advanced General Settings enables configuration of the active setting group as well as the minimum time the trip contact
will remain closed, to let the circuit breaker open the circuit so as the contact does not get burnt.
4.3.3.2 OTHER ADVANCED SETTINGS
Besides the Flex Curve values, the user may configure the mask of events that will generate an event report and the events
that will generate an oscillography.

(only two choices). For Boolean settings, the two possible options are shown so as the
user can select which one is the appropriate, clicking with the mouse on the option
desired.
For Numerical settings, a number must be entered. The program shows the minimum
and maximum value for each setting, and it will not accept any value out of the
corresponding range.
Select the appropriate one clicking on it.
A text box is shown.
