Solutions
1. check water supply
2. check water pump
З. set the water shortage current
lower than the water pump
operation current
1. check the water pump
2. check the wiring or the controller.
З. set the overcurrent higher
than the water pump normal
operation current
1. Check the circuit
2. Check the pump motor
1. Check power supply
and wiring
2. Replace controller.
З. Check circuit.
1. Check the probe / float wire.
2. Press the start key to resume
automatic operation and
check the current protection
t
range is reasonable.
З. Short the terminal @®
4. Switch the controller to
"Auto" mode
1. Check the input power
2. Check the input wiring
or controller.
1.Check the power
2.Check the pump or controller
3.Check the wiring
4.Change bigger transformer
Check the set parameters ,
voltages,circuits and parts
