Commissioning Manual
1. Apply a single-phase voltage 100% UBase to the U-Bus, and a single-phase
voltage 30% UBase to the U-Line.
2. Check that the AUTOENOK and MANENOK outputs are activated.
3. Increase the U-Line to 60% UBase and U-Bus to be equal to 100% UBase.
The outputs should not be activated.
4. The test can be repeated with different values on the U-Bus and the U-Line.
Testing the dead bus live line (DBLL)
The test should verify that the energizing check function operates for a low voltage
on the U-Bus and for a high voltage on the U-Line. This corresponds to an
energizing of a dead bus to a live line.
1. Verify the local HMI settings AutoEnerg or ManEnerg to be DBLL.
2. Apply a single-phase voltage of 30% UBase to the U-Bus and a single-phase
voltage of 100% UBase to the U-Line.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Decrease the U-Line to 60% UBase and keep the U-Bus equal to 30% UBase.
The outputs should not be activated.
5. The test can be repeated with different values on the U-Bus and the U-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% UBase to the U-Line and a single-phase
voltage of 100% UBase to the U-Bus.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Change the connection so that the U-Line is equal to100% UBase and the U-
Bus is equal to 30% UBase. The outputs should still be activated.
5. The test can be repeated with different values on the U-Bus and the U-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 U-Bus and the U-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 Off and ManEnerg to be DBLL.
2. Set the parameter ManEnergDBDL to On.
3. Apply a single-phase voltage of 30% UBase to the U-Bus and a single-phase
voltage of 30% UBase to the U-Line.
4. Check that the MANENOK output is activated.
5. Increase the U-Bus to 80% UBase and keep the U-Line equal to 30% UBase.
The outputs should not be activated.
6. Repeat the test with ManEnerg set to DLLB with different values on the U-
Bus and the U-Line voltage.
