A maximum of 16 levels are supported for the active power derating percentage.
"√" indicates a low level. When connecting to GND1, the four DI ports of the SmartLogger are
low-level ports. If not connected, the ports are high-level ports.
The percentage levels of DI1–DI4 should differ from each other. Otherwise, an abnormal command
will be generated.
If the actual input DI signal is inconsistent with that configured on the WebUI, the SmartLogger
controls the SUN2000 to work at full load and generates the
Abnormal Active Schedule
alarm.
