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
|
pump motor running ampere increasing was greater than the normal running ampere(calibrated ampere)by more than 200% |
cut off power supply&repair or replace pump immediately |
|
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 thepower 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
|
