If has been pressed the display shows, for example:
L: 49.70 Hz LFT
A: 49.99 Hz RUN
The limit „L:” will increase till crossing the actual measured grid frequency „A:”. Reached this condi-
tion the inverter disconnects from grid and the display shows, for example:
L: 49.99 Hz 0.044 S
A: 49.99 Hz LF pass
If the test is con rmed, the autotest routine is  nished. The display shows, for example:
Autotest Passed
Esc to continue
First line shows the actual autotest status. If all the single test are passed and con rmed, the actual
autotest status will be passed. Pressing „ESC” the display goes back to the main menu or the inver-
ter returns automatically to normal operation after 10 seconds.
If the actual autotest status is failed, press „ESC” and the display goes back to the main menu and
the inverter is in error condition. The display shows “ AUTOTEST FAILED”. If the actual status is
failed it is possible to restart the autotest routine. If the autotest permanently fails please contact
the customer service.
If during the autotest is performed any grid or inverter error occurs, the autotest routine is aborted
and the display shows the actual failed autotest status directly after new calibration.
The inverter resets and performs a restart if the previous status was passed.
The autotest can be started only if the inverter is in normal operating conditions. It is not possible
to entry the autotest routine if the grid is not in the de ned tolerances, if any internal inverter error
occurs or the solar plant do not respect the speci cations.
A restart of the inverter will be done after the autotest, when the result of the current autotest is
different from the result from the autotest before.
While the autotest routine is ongoing, green LED is  ashing, the red LED shows isolation measure-
ment status and the yellow LED shows the status of last autotest (yellow LED on: last autotest was
failed; yellow LED off: last autotest was ok).
The  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 con rmed and the autotest routine continue. If is not pressed, the result
is shown for 10 seconds. After this time, the result is con rmed automatically.
