9 Auto-test (only DK5940, see chapter 6)

The inverter is supplied with an auto-test function which enables the user to verify the
correct operation of the protection interface.
In order to select this function press the Sel/Set button until the message "AUTO TEST
SET" appears on the display panel. Press and hold the same button for at least 5
second, to initiate the auto-test procedure.

The first check to be made is the upper voltage threshold. The display panel shows
"V↑ 260V ≤0.1S", which is the value set for the upper voltage threshold and the
maximum delay admitted before the protection intervenes. By pressing the button,
the display shows the variation of the upper voltage threshold and the voltage value
of the mains supply as measured by the micro-controller. If the value of the
threshold and the mains supply voltage are equal the inverter switches to the "fault"
status (red LED on), by doing so the inverter disconnects from the grid and the
display panel shows for example a message similar to "T OK 232V -0.095S". This
means that the threshold voltage and the measured mains supply voltage have
become equal at 232V and the switching time is 0.095 seconds.

By pressing the button again the display panel shows the lower voltage threshold
check. The display shows a message similar to "V↓ 190V ≤0.2S", which is the
value set for the lower voltage threshold and the maximum delay admitted before
the protection intervenes. By pressing the button once again, the display shows
the variation of the lower voltage threshold and the voltage value of the mains
supply as measured by the micro-controller. If the value of the threshold and the
mains supply voltage are equal the inverter switches to the "fault" status (red
LED on), by doing so the inverter disconnects from the grid and the display panel
shows for example a message similar to "T OK 230V -0.19S". This means that
the threshold voltage and the measured mains supply voltage have become equal
at 230V and the switching time is 0.19" seconds.
