What to do if DAB PUMPS Inverter display shows OC?
- S
  Shawn BeasleyAug 19, 2025
  If the DAB PUMPS Inverter display shows OC, it could be due to several reasons: * Incorrect pump current setting (RC): Set RC with the current according to the type of connection (star or delta) as stated on the motor dataplate. * Excessive absorption: Ensure that the motor has all phases connected. * Pump blocked: Check that the impeller or motor is not blocked or obstructed by foreign bodies. * Inverted direction of rotation: Check the direction of rotation.

What to do if DAB PUMPS Inverter display shows BPx?
- T
  Toni RiggsAug 23, 2025
  If the DAB PUMPS Inverter display shows BPx, it indicates a problem with the pressure sensor. Here’s what to check: * Pressure sensor disconnected: Check the pressure sensor cable connection. Note that BP1 refers to the sensor connected to Press 1, BP2 to Press 2, and BP3 to the current sensor connected to J5. * Pressure sensor faulty: If the connection is secure, the pressure sensor may be faulty and needs replacement.

What to do if DAB PUMPS Inverter display shows OF?
- T
  Tyler BellAug 26, 2025
  If the DAB PUMPS Inverter display shows OF, it could be due to: * Excessive absorption: Check the type of connection (star or delta), ensure the motor doesn't absorb current over the maximum admissible value for the inverter, and verify that all motor phases are connected. * Pump blocked: Check that the impeller or motor is not blocked or obstructed by foreign bodies. Also, check the motor phase connections. * Pump absorbs high current on start-up: Reduce the acceleration parameter AC.

Why does the DAB PUMPS Inverter pump never stop?
- M
  meganjohnsonAug 28, 2025
  The DAB PUMPS Inverter pump might never stop because: * Minimum flow threshold FT setting too low: Set a higher FT threshold. * Short observation time: Set a higher FZ threshold. * Unstable pressure regulation: Wait for the self-learning process or run quick learning mode. * Incompatible use: Ensure that the system meets the operating requirements without the flow sensor. Attempt to reset by pressing MODE SET + - to recalculate conditions without the flow sensor.

Why does the DAB PUMPS Inverter pump stop even when not required?
- W
  Wendy CamachoAug 30, 2025
  The DAB PUMPS Inverter pump might stop even when not required due to: * Short observation time: Wait for the self-learning process or run quick learning mode. * Minimum frequency FL setting too high: If possible set a lower FL value. * Excessively high setting of minimum shutdown frequency FZ: Enter a lower threshold for FZ.

What to do if DAB PUMPS multi inverter system does not start?
- D
  Dwayne RomeroSep 2, 2025
  If the DAB PUMPS multi inverter system does not start, it might be because one or more inverters have an incorrect RC current setting. Check the RC current setting on each inverter.

What does it mean when DAB PUMPS Inverter display shows: Press + to align this config?
- J
  Jessica DixonSep 4, 2025
  If the DAB PUMPS Inverter display shows 'Press + to align this config', it means 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.

How to troubleshoot regulation pressure greater than SP on DAB PUMPS Inverter?
- A
  amarshallSep 6, 2025
  If the regulation pressure is greater than SP on your DAB PUMPS Inverter, it is likely that the FL setting is too high. Reduce the minimum operating frequency FL (if the electric pump enables this).

Why DAB PUMPS Inverter parameters are not propagatable in a multiple inverter system?
- W
  Wyatt CastilloSep 8, 2025
  If the parameters are not propagatable in your DAB PUMPS multiple inverter system, it could be due to: * Different passwords: Access each inverter individually and enter the same password on all, or remove the password. * Presence of non-propagatable configurations: Modify the configuration so that it is propagatable; it is not admitted to propagate configurations with FI=0 or FZ=0.

What to do if DAB PUMPS Inverter display shows EC?
- G
  Gary HarrisSep 12, 2025
  If the DAB PUMPS Inverter display shows EC, it means that the pump current (RC) is not set. You should set the parameter RC.
