Stop Display State
The inverter operation panel will display eight stop state parameters in stop state by
default, which are the same parameters as in operation state. Press can
sequentially left/right shift to display operation state parameters. In stop state,
RUN/STOP indicator light is off, RMT/LOC indicator light blinks and the corresponding
unit indicator lights of current display state parameter will turn on.
Fault Display State
The inverter operation panel will display blinking fault code and ALERT indicator light
turns on in fault state. Users can reset fault through , control terminal or
communication command. In fault state, users can still check state parameters through
as mentioned above. For fault code details, please refer to Chapter 5 Fault
Diagnosis and Solution.
Parameter Modication Display State
Press can enter parameter modification display state in operation, stop and
fault state. For details, please refer to section 4.2.1 Parameter Modification.
4.3 Initial Settings before First Operation
In order to ensure the efficient, reliable and stable operation of the solar pumping
system, it is necessary to change wiring of control terminal or set some of the inverter
function parameters according to the system configuration by professional electrical
technicians.
Please follow the steps below to complete the initial settings.
Step
Initial Setting Content
Operating Method
1
The inverter enables normally closed water level switch to
detect water level. To disable the function, connect DI3 to
COM or set function parameter F15.11 to 0
Set water level detection function

Under strong and stable radiation:
1. Observe water flow rate when the pump operates
stably
2. Exchange any two cables of the pump motor
3. Observe water flow rate when the pump operates
stably again
4. Compare and choose the wiring way with larger water
flow rate (operation frequency should be roughly the
same) to ensure forward rotation of the pump
Confirm pump motor wiring
2
If the rated parameters of the pump are inconsistent with
the inverter default settings, please modify function
parameters F02.01~F02.05 according to actual rated
parameters of the pump
Set rated parameters of the pump
If the rated frequency of the pump is inconsistent with the
inverter default setting, please modify function
parameter F00.03
Set the maximum operation frequency
of the pump
