3.5 Auto Test
This Auto Test function is stipulated in accordance with the Italian Standard DK5940. It enables verification of the voltage and frequency
monitoring function. The Auto Testing software as an accessory provided with the inverter should be installed on a PC connected up the inverter
through the RS-485 (or RS-232) port. Once the software is installed successfully, there is an execution file “SE Inverter Auto Test” created in
the “Start\Programs menu”.
For the overall duration of this auto-test, the inverter never exports power to the AC grid. To begin with, the relays will close to conduct the
max AC voltage threshold test as one of parts in auto-tests. Afterward the relays will open if this max AC voltage test is completed. Also, those
remaining parts in auto-tests will repeat in this way in order to check the whole function and responses in case of fault condition. The Auto
Test functionality and procedure is described as follows.
Double click the “SE Inverter Auto Test” and the software will search for all well-connected inverters with the PC; meanwhile the following
messages are shown.
