2.10 EVENTS (AVAILABLE IN OPTION 1 AND OPTION 2 MODELS)
2.10 EVENTS (AVAILABLE IN OPTION 1 AND OPTION 2 MODELS)
MIFII stores an historical record with the last 32 events. Each event contains the event description, date and time (4 ms
accuracy), the current values in phases and ground at that moment, and a summary of the status signals that can produce
events, and whether they were active or not in that moment.
In EnerVista MII SETUP there is an "EVENTS" menu, where the user can check how many events have been produced
since the last time the Events were deleted. If the number of events produced is higher than 32 (maximum number of
events stored), this means that only the last 32 will be stored.

This event record is stored in a capacitor backed up RAM memory. Events functionality in MIFII is performed via the
EnerVista MII SETUP software.
Inside the ADVANCED SETTINGS group, there is a sub-group called EVENT MASKS, from where the different causes that
can produce events can be masked. They are detailed in the SETPOINT – SETPOINT – ADVANCED SETTINGS – EVENT
MASK section. The following table shows a list of all possible events.
MIFII relay with option C stores an historical record with the last 100 events. Each register contains the event description,
date and time (4ms accuracy), the current values in phases and ground at that moment and a summary of the status
signals tha can produce events and whether they were active or not in that moment.
