    How to troubleshoot over current trip on BeiJer Inverter?
    • D
      daniel83Aug 18, 2025
      If the BeiJer Inverter trips due to over current, start by inspecting the motor and its connection cable for any phase-to-phase or phase-to-earth short circuits. Then, verify that the load isn't jammed, blocked, or stalled mechanically. Also, make sure the motor nameplate parameters (P1-07, P1-08, P1-09) are correctly entered. Try reducing the Boost voltage setting in P1-11 and increasing the ramp-up time in P1-03. Finally, if your motor has a holding brake, confirm it's properly connected, controlled, and releasing as it should.

    Why does my BeiJer HVAC H2 Inverter show over voltage?
    • A
      Alex ParksAug 20, 2025
      If your BeiJer Inverter is showing an over voltage fault, it's likely due to excessive regenerative energy from the load transferring back to the drive. To resolve this, increase the deceleration ramp time (P1-04) if the fault occurs when stopping or decelerating. Also, ensure that ramps are active by reducing P3-11.

    What to do if BeiJer HVAC H2 trips due to over load?
    • S
      Susan LopezAug 23, 2025
      If the BeiJer Inverter trips due to being overloaded, check when the decimal points are flashing (indicating an overload). Either increase the acceleration rate or reduce the load. Ensure the motor cable length is within the specified limit (refer to section 13.4). Verify that the motor nameplate parameters are correctly entered in P1-07, P1-08, and P1-09. Also, check the load mechanically for any jams, blockages, or mechanical faults.

    How to fix over temperature trip on BeiJer Inverter?
    • T
      Tammy MillsAug 26, 2025
      If your BeiJer Inverter is experiencing an over temperature trip, first, make sure the internal cooling fan is running. Then, check that the required space around the drive is maintained, ensuring the cooling airflow path isn't blocked (refer to sections 3.8 through 3.10). You can also try reducing the effective switching frequency setting in parameter P2-24, or reduce the load on the motor/drive.

    What causes high ambient temperature around BeiJer HVAC H2?
    • Z
      zdavisAug 28, 2025
      If the ambient temperature is high around your BeiJer Inverter, make sure the internal cooling fan is working. Also, ensure that there's enough space around the drive and that the airflow isn't restricted (check sections 3.8 through 3.10). Try increasing the cooling airflow to the drive, reducing the effective switching frequency setting in parameter P2-24, or decreasing the load on the motor/drive.

    What to do if BeiJer HVAC H2 detects low pressure during pipe fill?
    • J
      John FergusonAug 30, 2025
      If your BeiJer Inverter detects low pressure during the pipe fill function, check the pump system for leaks or burst pipes. Also, make sure the pipe fill function has been set up correctly using parameters P3-16 and P3-17.

    Why does BeiJer HVAC H2 Inverter exceed max torque?
    • S
      Stephanie CollinsSep 2, 2025
      If the BeiJer Inverter trips because the maximum torque is exceeded, check whether the mechanical load has changed and that the load isn't jammed or stalling. For pump applications, check for potential pump blockages. For fan applications, ensure the airstream to and from the fan isn't restricted.
