Operation 7.1 Parameter calibration and erasing To achieve the best performance of the controller and provide maximum protection to the pump, parameter calibration must be performed during installation, or during installation after the pump repairs. 7.1.1 Setting the parameter calibration Setting the parameters (calibration of unit according to the connected load): 1.

  • Page 27: Switching To Auto Mode

    7.1.2 Erasing the calibration After a pump repair or if a new pump is installed, the current parameters must be erased before the controller is re-calibrated. 1. Press the MODE button to switch to manual mode. Make sure the pump is not running. 2.

  • Page 28: Pump Protection

    7.4 Pump protection When the pump is in operation, if failures such as dry run, overload, or over-voltage occur, the controller will promptly stop the running pump. The controller will recover automatically after the default recovery time and once the abnormal situations have been cleared. If pump stalled, or other serious failure has occurred then the controller shall not recover automatically, pump user must immediately check incoming supply, pump and motor.
