The limit „L:" will increase till crossing the actual measured grid voltage „A:". Reached this condition
the inverter display shows, for example:
The fi rst line shows the limits according the standard. The second line shows the actual measured
trip limit and the test status if positive (pass). (If the test is negative (failed), press „ESC" and the
display goes back to the main menu and the inverter is in error condition.).
Pressing the test is confi rmed and the autotest routine continue. If
is shown for 10 seconds. After this time, the result is confi rmed automatically.
If the test is confi rmed, the inverter performs the HFT test, high frequency test, which verify the high
frequency protection. The display shows:
The fi rst line shows the actual high frequency limit and detection time settings according to the
standards. Since the protection is not sensitive to the frequency variations less than 40 ms (two
line cycles of the grid voltage at nominal frequency of 50 Hz), the detection time has been set to 60
ms. Pressing the test starts. Test starts also automatically after 10 seconds if

Pressing the test is confi rmed and the autotest routine continue. If
is shown for 10 seconds. After this time, the result is confi rmed automatically.
If the test is confi rmed, the inverter performs the LFT test, low frequency test, which verify the low
frequency protection. The display shows:
The fi rst line shows the actual low frequency limit and detection time settings according to the
standards. Since the protection is not sensitive to the frequency variations less than 40 ms (two
line cycles of the grid voltage at nominal frequency of 50 Hz), the detection time has been set to 60
ms. Pressing the test starts. Test starts also automatically after 10 seconds if
