![]()
- 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.
- If Active Power Control is set to AI remote control, Dry contact remote control is unavailable for Reactive Power Control.
