What to do if my DAB PWM II 230 D 4.7 display shows OF?

  If your DAB Inverter display shows 'OF', it could be due to several reasons. First, check for excessive absorption by verifying the type of connection (star or delta), ensuring the motor's current draw doesn't exceed the inverter's maximum admissible value, and confirming all motor phases are connected. Second, inspect the pump for blockages or obstructions caused by foreign objects, and check the motor phase connections. Lastly, if the pump absorbs high current during start-up, reduce the acceleration parameter AC.

What to do if my DAB PWM II 230 D 4.7 display shows BL?

  Tyler HebertAug 18, 2025
  If the display of your DAB Inverter shows 'BL', the possible causes are: no water, pump not primed, entry of setpoint too high for pump, inverted direction of rotation, incorrect setting of pump current RC, or maximum frequency too low. To solve this: prime the pump and ensure there is no air in the pipelines, and that intake or any filters are not obstructed. Also check that the pipeline from the pump to the inverter is not damaged or leaking. Lower the setpoint or use a pump suited to system requirements. Check the direction of rotation and set a correct value for pump current RC. If possible, increase FS.

What to do if my DAB Inverter display shows OC?
- A
  Angelica QuinnAug 22, 2025
  If your DAB Inverter displays 'OC', it could be due to several reasons: incorrect pump current setting (RC), excessive absorption, pump blockage, or inverted direction of rotation. To resolve this, set RC with the current according to the type of connection (star or delta) as stated on the motor dataplate. Also, check that the motor has all phases connected and inspect the pump to ensure that the impeller or motor is not blocked or obstructed by foreign bodies. Finally, check the direction of rotation.

Why does my DAB PWM II 230 D 4.7 Inverter pump never stop?
- I
  Ian StephensAug 25, 2025
  The pump might never stop because of unstable pressure regulation. To fix this, correct GI and GP.

What to do if my DAB PWM II 230 D 4.7 Inverter display shows LP?
- S
  Sarah LuceroAug 28, 2025
  If the display of your DAB Inverter shows 'LP', it could be due to low power supply voltage or excessive voltage drop on the line. Ensure the presence of correct line voltage and check the power cable section.

What does it mean when my DAB PWM II 230 D 4.7 Inverter display shows: Press + to align this config.?
- N
  Nicole NormanAug 31, 2025
  This message indicates that one or more inverters have sensitive parameters that are not aligned. Press the '+' button on the inverter that has the most recent and correct configuration of parameters.

What to do if regulation pressure is greater than SP on my DAB PWM II 230 D 4.7 Inverter?
- L
  Laura JohnsonSep 3, 2025
  If the regulation pressure is greater than SP, it means the FL setting is too high. Reduce the minimum operating frequency FL (if the electric pump enables this).

What to do if my DAB PWM II 230 D 4.7 Inverter display shows SC?
- S
  Samantha ManningSep 6, 2025
  If the display on your DAB Inverter shows 'SC', it indicates a short circuit between phases. To solve this, ensure that the motor is in the correct condition and check its connections.

Why does my DAB PWM II 230 D 4.7 Multi-inverter system not start and says firmware incompatible?
- J
  Jessica ToddSep 9, 2025
  The Multi-inverter system might not start and displays 'firmware incompatible' because the firmware is not aligned with the same version on all inverters. Perform the automatic update procedure among inverters.
C
Clarence SchmittSep 12, 2025
Why does my DAB PWM II 230 D 4.7 Inverter Multi-inverter system not start and says products incompatible?
- A
  Amanda HarperSep 12, 2025
  The Multi-inverter system may not start and indicates 'products incompatible' if products of different types or sizes are in communication with one another. To resolve this, use inverters of the same type and size to create multi-inverter systems.
