A maximum of 16 levels are supported for power factors.
"√" indicates low level. When connecting to GND2, the four DI ports of the SmartLogger are
low-level ports. If not connected, the ports are high-level ports.
The status combination of DI1(GND2)–DI4(GND2) should differ from each other. Otherwise,
abnormal command parsing will occur.
If the actual input DI signal is inconsistent with that configured on the WebUI, the SmartLogger
does not allow the SUN2000 to generate reactive power and the
Abnormal Reactive Schedule
alarm is generated.
