By pressing the “OK” button again the display panel will show the lower frequency threshold check. The display will show a message similar to “f

0.06s”, which is the value set for the lower frequency threshold and the maximum delay admitted before the protection intervenes (in reality
the display would not show this value, as the 0.06s step (3 cycles) has only been shown as the protection is not sensitive to the frequency variations less
than 40ms (two cycles)). By pressing the button once again, the display will show the variation of the lower frequency threshold and the frequency
value of the mains supply as measured by the micro-controller. If the value of the threshold and the mains supply frequency are equal the inverter will
switch to the “fault” status, by doing so the inverter will disconnect from the grid and the display panel will show for example a message similar to “T
OK 50Hz -60ms”. This means that the threshold and the measured mains supply frequency have become equal at 50Hz and the switching time is 60
milliseconds.
The “AUTO TEST” function is considered successful once all the previous 4 tests have been performed: in this case the message "TEST PASSED" will
appear on the display panel. By pressing the “OK” button, the inverter will switch to the normal operation mode (only if the mains supply is with the
specified tolerances). If one of the previous 4 tests fail, the display shows the message "AUTO TEST FAILED" and the inverter will permanently
switch to the “fault condition”. In this case contact the customer service center in order to return the inverter normal operation.
