  Tasha TranSep 7, 2025
  If the MAC3 Controller detects a 'High Peak Current', it means the drive has measured excessive power consumption. Verify that the pump is used under the conditions prescribed by its manufacturer and ensure there are no conditions of friction or locking of the impeller. You can also change the peak current value on parameter 54.

  Carla GonzalezSep 5, 2025
  If the MAC3 Controller detects 'Overcurrent', it means there is too much current in the pump. You should check the current measurement output parameter to 'LoadCurrent' and set the proper parameter 'Max.MotorCurrent'. Verify that the pump is used under the conditions prescribed by its manufacturer and make sure that there are no conditions of friction or locking of the impeller.

What to do if MAC3 HydroController HCW-MM Controller shows Dry Running error?
- M
  Melanie TrevinoSep 2, 2025
  If the MAC3 Controller indicates 'Dry Running', it means there's a lack of water. In the HCW version, the check valve might be closed while the pump is running. In the HCA version, the measured power is below the value set on the 'Dry Run Power' parameter. Check for water presence. In the HCW model, verify the check valve. In the HCA model, verify the value of 'Dry Run Power'. Reset the correct pump priming function. Check that the filter is not blocked. Disconnect the power supply and wait for the display to switch off, then reconnect the power supply.

  If the MAC3 Controller is showing 'High Temperature', it means the internal temperature of the inverter is high (over 75 °C). Check that the ingoing water temperature is within the product specifications. In the HCA model, verify the correct functioning of the cooling fan. Also, check and restore the correct pump priming action.
