What to do if Franklin Electric Control Unit shows overcurrent or locked pump?
- H
  Heather RodriguezAug 12, 2025
  If you are experiencing overcurrent or a locked pump with your Franklin Electric Control Unit, the cause may be motor and/or pump misalignment, dragging or locked motor and/or pump, abrasives in the pump, or excess motor cable length. If the amperage is above SFL at 30 Hz, remove and repair or replace the affected components as required. Also, reduce the motor cable length, adhering to the Maximum Motor Cable Length table.

What to do if Franklin Electric Control Unit indicates open phase?

  James LopezAug 16, 2025
  If you have an open phase issue with your Franklin Electric Control Unit, it could stem from a loose connection, a defective motor or drop cable, or using the wrong motor. Check the drop cable and motor resistance, and tighten the output connections. Repair or replace components as necessary. You can use a dry motor to check drive functions. If the drive runs and exhibits an underload fault, the drive itself is likely in good condition.

Why is my Franklin Electric SUBDRIVE CONNECT showing undervoltage?
- R
  Randy PrinceAug 25, 2025
  If your Franklin Electric DC Drives system shows undervoltage, it could be due to several reasons. First, the line voltage might be too low, less than approximately 150 VAC (normal operating range is 190 to 260 VAC). Also, check for misconnected input leads or loose connections at the breaker or panel. To resolve this, check and correct the incoming power connections, ensuring they are tight. You may also need to check the circuit breaker or fuses, and if the voltage is still incorrect, contact your power company.

  Elizabeth FlemingAug 27, 2025
  If your Franklin Electric DC Drives system is experiencing overcurrent or the pump is locked, it could be due to motor or pump misalignment, dragging, or being completely locked. Abrasives in the pump or excessive motor cable length can also cause this. Amperage may be above SFL at 30 Hz. To address this, remove and repair or replace the affected components as needed. Also, reduce the motor cable length, adhering to the Maximum Motor Cable Length table.

How to troubleshoot motor underload on Franklin Electric SUBDRIVE CONNECT DC Drives?
- K
  Kimberly RobinsonDec 1, 2025
  If your Franklin Electric DC Drives motor is underloaded, several factors could be at play. The well might be over-pumped, or there could be a broken shaft or coupling. A blocked screen, worn pump, air/gas locked pump, or incorrect SubDrive settings for the pump end could also be the cause. Additionally, the Underload Sensitivity setting might be incorrect, with the frequency near maximum but the load less than the configured underload sensitivity. The system might be drawing down to the pump inlet (out of water). If it's a high static, light loading pump, reset the Potentiometer for less sensitivity if not out of water. Check the pump rotation (SubDrive only) and reconnect if necessary for proper rotation. For an air/gas locked pump, if possible, set it deeper in the well to reduce air/ga...
