The rst line shows the limits according the standard. The second line shows the actual measured
grid voltage and the test status, positive (pass) or negative (fail). Pressing the test is con rmed
and the auto-test routine continue. If no is pressed, the result is shown for 1minute. After this
time, the result is con rmed automatically.
The rst line shows the limits according the standard. The second line shows the actual measured
grid frequency and the test status, positive (pass) or negative (fail). Pressing the test is con rmed
and the auto-test routine continue. If no is pressed, the result is shown for 1minute. After this
time, the result is con rmed automatically.
The 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 1 minute if no is pressed.
The 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 1 minute if no is pressed.
If has been pressed the display shows, for example:
The limit “L:” will increase till crossing the actual measured grid voltage “A:”. Reached this condition
the inverter display shows, for example:
L: 230 V 0.164 S
A: 230 V UV pass
If the test is con rmed, the inverter performs the HFT test, high frequency test, which verify the high
frequency protection. The display shows:
L: 50.30 Hz < 0.06 S
Start HFT test?
L: 50.30 Hz HFT
A: 49.99 Hz RUN
The limit “L:” will decrease till crossing the actual measured grid frequency “A:”. Reached this con-
dition the inverter display shows, for example:
L: 49.99 Hz 0.044 S
A: 49.99 Hz HF pass
If the test is con rmed, the inverter performs the LFT test, low frequency test, which verify the low
frequency protection. The display shows:
L: 49.70 Hz < 0.06 S
Start LFT test?
