communication.
Minimum voltage value of the positive phase-sequence voltage during the

last fault conditions in the network, measured as a multiple of the rated
voltage U

and of the external trip, shown as a percentage of the set operate time, or of
the calculated operate time at IDMT characteristic. A value other than zero
indicates that the corresponding stage has started whereas a value which is
100% of the set or calculated operate time indicates that the operate time of
the stage has elapsed, that is, the stage has tripped. If the operate time of a
stage has elapsed but the stage is blocked, the value is 99% of the set or
calculated operate time.
Time stamp for the event. The time when the collected data was stored. The

time stamp is displayed in two registers, one including the date expressed as
yy-mm-dd, and the other including the time expressed as HH.MM;SS.sss.

EVENT 3 Same as EVENT 1.
EVENT 4 Same as EVENT 1.
EVENT 5 Same as EVENT 1.

When the counters reach their maximum values (65535), they roll over.

Communication ports

The relay is provided with an optical communication port (infrared) on the front
panel. Rear communication is optional and requires a communication module,
which can be provided with either a plastic fibre-optic, combined fibre-optic (plastic
