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 2FUNCTION 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 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.
