Unloading correct information from the recorder requires that M80 and M83 have
been set. Unloading is done by using a PC application. The uploaded recorder data
is stored in separate files defined by the comtrade® format.

Event code of the disturbance recorder

The disturbance recorder generates an event code on triggering (E31) and clearing
(E32) the recorder. The event mask is determined using SPA parameter V155.

Recorded data of the last events

The relay records up to five events. This enables the user to analyze the last five
fault conditions in the electrical power network. Each event includes the measured
currents, start durations and time stamp, for instance. Additionally, information on
the number of starts of the stages, trips and auto-reclose shots is provided.
Recorded data is non-volatile by default, provided that the battery has been inserted
and is charged. A master reset, that is, clearing of indications and memorized values
and unlatching of output contacts, erases the contents of the stored events and the
number of starts of the stages.
The number of trips and auto-reclose shots is stored in the non-volatile
memory (EEPROM) and is thereby not cleared when performing a
master reset. The number of trips can be erased by entering the value 1
and the number of auto-reclose shots by entering the value 2 into
parameter V166.
The relay collects data during fault conditions. When all start or thermal alarm
signals have been reset or a stage trips, the collected data and time stamp is stored as
EVENT1 and the previously stored events move one step forward. When a sixth
event is stored, the oldest event is cleared.
