Parameter Setting
Alarm 2 Set 100 operations
With these settings, Alarm 1 is issued when the cumulative interruption counter for any of the three
phases dips below the set 1000 remaining operations ("Alarm 1 Set"). Similarly, when any of the
counters dips below 100 remaining operations, Alarm 2 is issued.
Events and registers
The circuit breaker wear function (abbreviated "CBW" in event block names) generates events and
registers from the status changes in Triggered, Alarm 1 and Alarm 2 signals as well as in internal pick-
up comparators. The user can select which event messages are stored in the main event buffer: ON,
OFF, or both.
The events triggered by the function are recorded with a time stamp and with process data values.

Event number Event channel Event block name Event code Description
3712 58 CBW1 0 CBWEAR1 Triggered
3713 58 CBW1 1 CBWEAR1 Alarm 1 ON
3714 58 CBW1 2 CBWEAR1 Alarm 1 OFF
3715 58 CBW1 3 CBWEAR1 Alarm 2 ON
3716 58 CBW1 4 CBWEAR1 Alarm 2 OFF
The function registers its operation into the last twelve (12) time-stamped registers. The register of the
function records the ON event process data. The table below presents the structure of the function's
register content.

5.5.4 Fault locator (21FL)
The fault locator function is used for recording an estimated distance to the point where a fault has
occurred. It is mostly used in directional overcurrent protection or distance protection applications but
can be also triggered by other protections. The function can be used if all three phase currents and
three phase voltages have been connected to the relay. The triggering signals, the triggering current
and "Reactance per km" must be set in the configuration.
The inputs for the function are the following:
• operating mode selections
• setting parameters
• digital inputs and logic signals
• measured and pre-processed current magnitudes.
The function generates general time-stamped ON/OFF events to the common event buffer from each
of the two (2) output signals. The time stamp resolution is 1 ms. The function also provides a resettable
cumulative counter for the fault locator triggering events.
