Start the test with ON+TIME. For each fault X, the display
shows on one line two test results: to the right, the relay trip
delay; to the left, the reclose delay. Test result time are four
digits with autoranging, so that the percent accuracy is the
same for fast and slow reclose times. It is possible to monitor
the test evolution looking at these times, and also at the STOP
and START lights ; the TRIP light follows the relay trip.
For the first test sequence, all tests will have two meaningful
timings ; for the second one, after the last test, the START
light will not turn on : this confirms that the Recloser has
expired all the programmed reclose attempts.
In all instances, as the test is over, the ON+TIME light turns
off, the test set goes to OFF, and the display shows the
message of results recording.
Remember that, if N is the programmed number of Reclose
commands, at the end of the test there will be N+1 results in
memory.
For the second test sequence, the last time result will be 0 s,
confirming that there was no trip within 10 times the last
measured reclose delay.
