Commissioning Manual
1.
Verify the settings AutoEnerg or ManEnerg to be DBLL.
2.
Apply a single-phase voltage of 30% GblBaseSelBus to the V-Bus and a single-
phase voltage of 100% GblBaseSelLine to the V-Line.
3.
Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg respectively tManEnerg.
4.
Decrease the V-Line to 60% GblBaseSelLine and keep the V-Bus equal to 30%
GblBaseSelBus. The outputs should not be activated.
5.
The test can be repeated with different values on the V-Bus and the V-Line.
Testing both directions (DLLB or DBLL)
1.
Verify the local HMI settings AutoEnerg or ManEnerg to be Both.
2.
Apply a single-phase voltage of 30% GblBaseSelLine to the V-Line and a single-
phase voltage of 100% GblBaseSelBus to the V-Bus.
3.
Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg respectively tManEnerg.
4.
Change the connection so that the V-Line is equal to100% GblBaseSelLine and
the V-Bus is equal to 30% GblBaseSelBus. The outputs should still be activated.
5.
The test can be repeated with different values on the V-Bus and the V-Line.
Testing the dead bus dead line (DBDL)
The test should verify that the energizing check function operates for a low voltage on
both the V-Bus and the V-Line, that is, closing of the breaker in a non-energized
system. Test is valid only when this function is used.
1.
Verify the local HMI setting AutoEnerg to be Disabled and ManEnerg to be
DBLL.
2.
Set the parameter ManEnergDBDL to Enabled.
3.
Apply a single-phase voltage of 30% GblBaseSelBus to the V-Bus and a single-
phase voltage of 30% GblBaseSelLine to the V-Line.
4.
Check that the MANENOK output is activated after set tManEnerg.
5.
Increase the V-Bus to 80% GblBaseSelBus and keep the V-Line equal to 30%
GblBaseSelLine. The outputs should not be activated.
6.
Repeat the test with ManEnerg set to DLLB with different values on the V-Bus
and the V-Line voltage.
