System Diagnostics Fault History

The SubDrive Connect continuously monitors system performance and can detect a variety of abnormal
conditions. In many cases, the drive will compensate as needed to maintain continuous system operation;
however, if there is a high risk of equipment damage, the drive will stop the system and display the fault
condition. If possible, the drive will try to restart itself when the fault condition subsides. Each time a fault is
detected in the system, the drive records the fault with the date and time the fault was detected. A maxi-
mum of 500 events are recorded and can be viewed and emailed using the FE Connect mobile app.

Diagnostic Fault Codes

Code Fault
F1 Motor Underload
F2 Undervoltage
F3 Overcurrent or
Locked Pump
F4 Incorrectly Wired
F5 Open Phase
36.
Possible Cause
• Over-pumped well
• Broken shaft or coupling
• Blocked screen, worn pump
• Air/gas locked pump
• SubDrive not set properly for
pump end
• Underload Sensitivity setting
incorrect
• Low line voltage
• Misconnected input leads
• Loose connection at breaker or
panel
• Motor and/or pump
misalignment
• Dragging motor and/or pump
• Motor and/or pump locked
• Abrasives in pump
• Excess motor cable length
• Wrong resistance values on main
and start
• Loose connection
• Defective motor or drop cable
• Wrong motor
Corrective Action
• Frequency near maximum with load less than configured
underload sensitivity (Potentiometer or Wi-Fi)
• System is drawing down to pump inlet (out of water)
• High static, light loading pump - reset Potentiometer for less
sensitivity if not out of water
• Check pump rotation, reconnect if necessary for proper
rotation
• Air/gas locked pump - if possible, set deeper in well to reduce
• Verify DIP switches are set properly
• Check Underload Sensitivity Setting (Potentiometer or Wi-Fi
setting, whichever is applicable)
• Line voltage low, less than approximately 150 VAC (normal
operating range = 190 to 260 VAC)
• Check incoming power connections and correct or tighten if
necessary
• Correct incoming voltage - check circuit breaker or fuses,
contact power company
• Amperage above SFL at 30 Hz
• Remove and repair or replace as required
• Reduce motor cable length. Adhere to Maximum Motor Cable
Length table.
• Check wiring, check motor size and DIP switch setting, adjust
or repair as needed
• Open reading on DC test at start.
• Check drop cable and motor resistance, tighten output
connections, repair or replace as necessary.
• Use dry motor to check drive functions. If drive runs and
exhibits an underload fault, drive is good.
