0 and can be set to 0 or 1 by calibrating the software. If it is 1 under "Local" mode, the testing order
will be 59.S1, 59.S2, 27.S1, 81>S1, 81<S1. Otherwise, the testing order will be 59.S1, 59.S2, 27.S1,
81>S2, 81<S2.
Connect AC, then the auto test will start after the inverter relay breaks off successfully: output
power is zero and LCD shows the information about testing.
If sub test finishes and LCD displays "Test ***** Ok", the inverter relay willbreak off and reconnect
to grid automatically according to CEI 0-21 requirement. Then the next test starts.
If sub test fails, the inverter relay breaks off and enter wait mode. To retry, the inverter needs to be
totally powered off and be restarted.
