•
Set the Failure to close timer to the maximum. Perform a closing command and check that during the
failure to open time the Reclose-1 (C1-D1) and Reclose-2 (C2-D2) output contacts are closed.
•
Enable only 51P function, and set it to its minimum value. Inject a current to phase A equal to 2xIn(phase)
to trip the relay. Check that S1 auxiliary output (C4-C6) closes and also S9 (E1-F1) if an expansion board
exists.
•
Enable only 51N function, and set it to its minimum value. Inject a current to the ground input equal to
2xIn(ground) to trip the relay. Check that S2 auxiliary output (D4-C6) closes and also S11 (E3-F3) if an
expansion board exists.
•
Enable only 46 function, and set it to its minimum value. Inject a current to phase A equal to 2xIn(phase)
to trip the relay. Check that S3 auxiliary output (C5-C6) closes.
•
Enable only 81O function, and set it to its minimum value. Inject nominal voltage on phase B voltage
input, at nominal frequency to trip the relay. Check that S4 auxiliary output (D5-C6) closes.
•
Enable only 59P function, and set it to its minimum value. Inject nominal voltage on phase A voltage
input, at nominal frequency to trip the relay. Check that S5 auxiliary output (C7-D6) closes.
•
With the recloser out of service check that output S8 (D8-D6) is closed. Set the recloser in service and
check the S8 opens. Set the recloser to one reclosing attempt with a 5 sec time delay, without reclosing
condition checking and a reset time equal to 10 sec. Enable only 51P function and make the relay to trip.
Check that S7 closes (C8-D6) during the 5 sec the recloser lasts. Before 10 sec make the relay to trip
again and check the recloser moves to the lockout status, closing output number S6 (D7-D6).
•
Remove the Power Supply to the relay and check that the Alarm contact (C3-D3) closes. Set the power
supply back to the relay and check that the Alarm contact opens.
