Recorded data
Parameter V1 indicates the highest and parameter V2 the lowest voltage value
measured as multiples of the rated voltage U
shows the average voltage value during one minute's time, updated once a minute.
The average voltage during a ten minutes' period is shown by parameter V4. The
value is updated for the first time ten minutes after the relay start-up and after that
once a minute. Parameters V5...V8 indicate the number of starts of the protection
stages, parameter V9 shows the operation indication code and parameter V10 the
stage that has tripped.
