4. Auto Test

The Auto Test function is required according to the Italian DK5940 standard. It
enables verifi cation of the voltage and frequency monitoring function. The Auto
Test option is only available in the main menu if "IT" (Italy) was selected as the
installation location.
The Auto Test functionality and procedure is described below.
4.1 Auto Test defi nition according to DK5940 (Italy)
During the Auto Test procedure in mains mode the trigger threshold for AC voltage
and frequency monitoring is varied linearly with a ramp of ≤ 0.05Hz/s and ≤ 0.05
Vn/s (Vn = 230 Vac). At some point during the test the threshold will coincide with
the current measured value, leading to triggering of the monitoring intervention.
After each test step the values of the trigger thresholds, delay times, current meas-
ured frequency and AC voltage values, and the standard threshold trigger value are
displayed.

4.2 Start Auto Test

To start the Auto Test the inverter must be installed as described in Section 3. The
Auto Test can be activated only if there is suffi cient irradiance and the inverter is
connected to the mains and is in feed mode.
1. Wait until the inverter has connected itself to the mains.
2. Select Auto Test in the main menu.
3. Answer the question whether the Auto Test should be executed with YES.
4. The Auto Test now runs automatically.
