Solutions |
|
flashing of
|
the real running voltage is lower than the calibrated voltage, pump is in under voltage protection state |
report lowline voltage to the power supply company |
|
controller will attempt to restart the pump every 5minutes untilline voltage is restored to normal |
||
|
flashing of
|
the realrunning voltage is higher than the calibrated voltage, pump is in over voltage protection state |
report highline voltage to the power supply company |
|
controller will attempt to restartthe pump every 5minutes untilline voltage is restored to normal |
||
|
flashing of
|
the real running ampere is higher than the calibrated running ampere, pump is in over load protection state |
controller will attempt to restart the pump every 30minutes until running ampere is restored to normal |
|
pump impeller is jammed / pump motor dragging /pump bearing broken |
check pump impeller orbearing |
|
|
flashing of
|
power supply lose phase |
report to the power supply company |
|
controller inlet wire or pump cable broken |
repair inlet wire or pump cable |
|
|
flashing of
|
parameter calibration not completed |
refer to parameter calibration setting |
|
flashing of
|
liquid level in the well / sump is below the pump intake,pump stops running |
controller will attempt to restart the pump every 30minutes until liquid level above the pump intake |
|
flashing of
|
pump motor running ampere increasing was greater than the normal running ampere(calibrated ampere)by more than 200%1111 |
cut off power supply&repair or replace pump immediately |
|
|
no communication link between SC / computer and controller |
connecting the controller to SC /computer to realizelong distance monitoring |
Installation
Electrical connection to the power supply line and electrical pump
- DANGER Electric shock risk
Before carrying out any installation or maintenance operation, the controller should be disconnected from the power supply and one should wait at least 2 minutes before opening the appliance.
- Never connect AC power to output UV W terminals.
- Don't put wire, metal bar filaments etc into the controller.
- Ensure the motor, controller and power specifications matching.
- The electrical and hydraulic connections must be carried out by competent, skilled, qualified personnel.
