SubDrive/MonoDrive Troubleshooting (Continued)
SubDrive15, 20, 30, MonoDrive, and MonoDriveXT (NEMA 3R)
Diagnostic Fault Codes
| NUMBER OF FLASHES | FAULT | POSSIBLE CAUSE | CORRECTIVE ACTION |
| F14 | BROKEN PIPE | - Broken pipe or large leak is detected in the system - Drive runs at full power for 10 minutes without reaching pressure setpoint - Large water draw, such as a sprinkler system, does not allow system to reach pressure setpoint | - Check system for large leak or broken pipe - If the system contains a sprinkler system or is being used to fill a pool or cistern, disable the Broken Pipe Detection |
| F15 (SD15/20/30 only) | PHASE IMBALANCE | - Motor phase currents differ by 20% or more. - Motor is worn internally - Motor cable resistance is not equal - Incorrect motor type setting (single- or three-phase) | - Check resistance of motor cable and motor windings - Verify motor type matched drive settings (single- or three-phase) |
| F16 | GROUND FAULT | - Motor output cable is damaged or exposed to water - Phase to ground short | - Check motor cable insulation resistance with megger (while not connected to drive). Replace motor cable if needed. |
| F17 | INVERTER TEMPERATURE SENSOR FAULT | - Internal temperature sensor is malfunctioning | - Contact your Franklin Electric Service Personnel - If problem persists, unit may require replacement. Contact your supplier. |
| F18 (SD20/30/MDXT only) | PFC TEMPERATURE SENSOR FAULT | - Internal temperature sensor is malfunctioning | - Contact your Franklin Electric Service Personnel - If problem persists, unit may require replacement. Contact your supplier. |
| F19 | COMMUNICATION FAULT | - Cable connection between Display/Wi-Fi Board and Main Control Board is loose or disconnected - Internal circuit failure | - Check cable connection between Display/Wi-Fi Board and Main Control Board. - If problem persists, unit may require replacement. Contact your supplier. |
| F22 | DISPLAY/WI-FI BOARD EXPECTED FAULT | - Connection between Display/Wi-Fi Board and Main Control Board was not detected at drive start-up | - Check cable connection between Display/Wi-Fi Board and Main Control Board. - If problem persists, unit may require replacement. Contact your supplier. |
| F23 | MAIN BOARD STARTUP FAULT | - A fault was found internal to drive | - Contact your Franklin Electric Service Personnel - Unit may require replacement. Contact your supplier. |
| F24 | INVALID DIP SWITCH SETTING | - No DIP Switch set or more than one (1) DIP Switch set for Motor size - No DIP Switch set or more than one (1) DIP Switch set for Pump size - Invalid combination of DIP switches for drive type (SD or MD mode), Motor hp, and Pump hp. | - Check DIP switch settings |
- Power down, disconnect leads to the motor and power up the SubDrive:
- - If the SubDrive does not give an “open phase” fault (F5), then there is a problem with the SubDrive.
- - Connect the SubDrive to a dry motor. If the motor goes through DC test and gives “underload” fault (F1), the SubDrive is working properly.
