Trial run(How to start solar pump inverter)
Make sure all cables connections of solar panel and pump motor
correct and no
need to set any parameter, if you want to set parameter, you can do
as follows.
Step 1: (Keypad control):Set motor parameter P11.02- P11.06 as per
motor pump name
plate If dry run protection is required, measure the unload
protection current(see details in
user manual chapter for dry run function) If dry run protection not
required then miss this step
and go to step 2.
Step 2: Set other related special solar pump parameters for
optimization if needed.
Step 3: After trial run finishing, if motor pump still not output
water when inverter is running
more than 40 Hz. Please disconnect the power supply and replace any
two-phase wiring of
the motor
Technical Questions and solutions
1. How to achieve Automatic start after stop?
If it is controlled by keyboard, so there is no need to set any
parameter(P47.03 waiting time)If you want to
control by external switch. First set P00.06=1 and use a wire or
switch to connect com and DI1,When the
switch is closed, the drive run, when the switch is open, the drive
stop
2. How to use a float in the water tank to stop the pump if the
tank is full?
If your float signal is digital signal Use float switch to short DI
3 and com ,see diagram 1.3
143.Use level probe in the well for protection against dry running
1 st solution: See self learning of dry run(For LED display)
2 nd solution: do it manually Set P24.13=30%-60%(as per real empty
load current percentage based on
rated current) and P24.14 P24.16 and P23.21
3 rd solution: If your sensor is digital switch, just short D4 and
com
4 th solution: If your float signal is Analog signal, Connect Ai2
and 10V and GND and set P41.00=23 and
P41.03-P41.06
