Running
◎
The controller can be powered on after the wiring is completed and the cover is
installed. It is strictly forbidden to remove the cover when the power is on, otherwise it may
cause electric shock.
◎
The water pump must be installed before testing the steering of the water pump. The
water pump should not be allowed to do dry run for a long time. In order to test the steering
of the water pump, the maximum running time of dry running should not exceed 15s.
◎
If the rotation of the water pump is reversed, any two of the three cbales of the
controller output side can be changed.
◎
When the water pump stops due to weak sunlight or sudden shadow, it will restart
after 300s.
◎
If there is a water level probe installed in the well, the pump will stop running when
it is lower than the water shortage level.
