Chapter8.Installation and Spare Circuit
1. Wiring in accordance with the wiring diagram and closing the switch Q1 after
checking the corrected wiring.
2. y0.00=1(Factory Reset); Set b0.00 ~ b0.05 motor parameters according to the motor
nameplate.
3.Set F0.03 = 8 (PV settings); E0.00 = 2 (MPPT mode);
4.After setting the parameters, press the RUN key, observe the operating frequency and
the water situation. In normal light conditions, if running frequency is high but the water
is running less, it indicates motor reversal phenomenon and need to modify the F0.24 =
1, then observe the water.
5.Set point of failure and fault reset time delay settings. If the customer needs to use the
weak light, full of water, under-load, you can set detection point , the number of
automatic reset and automatic reset time are set as per customer's request.
(There are many different types of level switches, set parameters according to the site
requirement. The following are examples.)
(1) When the sunlight is weak, the frequency inverter turn into hibernation. When
the sunlight is strong, the frequency inverter automatically wake. Set E0.07 ~
E0.08 voltage detection value.
Take 380V voltage level as an example:
Parameter settings: F0.03 = 8 (PV settings);
E0.00 = 2 (MPPT mode);
E0.07 = 530 (PV wake voltage);
E0.08 = 400 (PV dormant voltage);
If the frequency inverter operate normally and when the sunlight is weak, the bus
voltage becomes less than 400V, then the frequency inverter enters into hibernation.
When the sunlight is strong, the bus voltage is greater than 530V, the frequency inverter
will automatically start running. Set the voltage of PV wake and sleep according to the
situation. The two values can not be set at too close, if setting too close, the frequency
inverter may start and stop frequently.
(2) Water level detection mode 1- Switch detection.
When using the switch detection, the test line lead to DI terminal, Then the
corresponding terminal is set to 8. If used as a feedback input signal DI2, DI2 = 8.
When filled with water, DI2 signal is active, the frequency inverter will free stop. When
the water level is below the detection value, the corresponding terminal is set to 1. (As
with DI1 as the start signal, DI1=1), frequency inverter starts automatically.
