Connect the test line according to the figure.
Set parameters: F0.03 = 8 (PV settings))
F0.11 = 4 (keyboard + Terminal + communication);
F1.00 = 1 (forward run);
F1.01 = 8 (freewheel);
F1.10 = 2 (three-wire mode 1)
E3.02 = 3 (three-wire operation control);
E3.05 = 00100;
E0.00 = 2 (MPPT mode);
After setting the parameters, press the RUN key, frequency inverter runs. If water
reaches the high lever detection point, the frequency inverter will free stop. When the
water level falls below the low level detection point, the frequency inverter
automatically starts running.
（3）Water level detection mode 2- Analog detection.
When using analog detection，AI terminals will lead to the detection line and connect
to the cable according to the wiring diagram. Water-filled test point voltage is 7V. When
AI1 detects 7V voltage, the freq frequency inverter will free stop. When AI1 detects
voltage is lower than 3V , the frequency inverter automatically starts running.
