3.2.2. Event menu
The event menu (Main menu\Measured values\Events) contains the
function block name and the event in the same manner as the indication messages
(see “Indication messages” on page 22). The first view of the event menu shows the
amount of events (maximum 50). The most recent event is stored on top of the list.
When a certain event is selected, date and time of the event in question can be read
by moving one step right with the [
→ ] button. If the event in question is a trip event
and its data in the recorded data menu (Main menu\Protection\…\
Recorded data1\…3\) has not been overwritten, it is possible to move directly
to the associated recorded data by moving right [
→ ] again in the date and time view.
Return to the event view with the [C] button or with the [
← ] button, like in normal
menu navigation. When viewing recorded data, the return is directed to the event
summary view (Main menu\Measured values\Events) if
• the recorded data is overwritten, or
• the original event is overwritten in the event list, or
• the event list is cleared.
These events are stored in the non-volatile memory, which means that they can alse
be seen after a disconnection of the power supply. When displayed, the event list can
be cleared by pressing the [C] button for 2 seconds.
