Troubleshooting

43

F22

Control Board Fault

• EEPROM error
• Bluetooth error

• Cycle power to see if fault resets.
• Check cable connection between Control Board and Power 

Board. Check all programming parameters.

• Verify all programming parameters
• Reset the drive to factory default settings, refer to 

“Special 

Functions” on page 27

.

• If problem persists, note the sub-fault number on the display 

before contacting the FE Service personnel.

F25

Moisture Sensor Fault • Moisture Sensor has detected 

moisture or water

• External device wired to the WET 

SENSOR terminal has satisfied 
the configured fault condition

• Input is incorrectly configured

• Check Moisture Sensor location for moisture or presence of 

water. Clean and dry area. Drive will restart when moisture or 
water is no longer detected.

• Ensure Moisture Sensor input is configured/wired correctly

F27

Pressure Transducer 

Error

• Pressure transducer has failed
• Pressure transducer is incorrectly 

wired

• Pressure transducer signal is 

outside of the expected range

• Pressure transducer is 

disconnected

• Incorrect sensor type setting

• Check pressure transducer wiring connections; tighten or 

correct, if necessary

• Ensure sensor type setting is correct
• Replace pressure transducer

F28

Real Time Clock Fault

not displayed, but 

logged.

• Internal real time clock is not 

programmed

• Real time clock battery on 

Control Board is loose

• Real time clock battery is dead

• Ensure battery is properly inserted. If corrected, reconnect to 

drive using mobile app to reset the internal clock time

• Replace battery. If replaced, reconnect to the drive using the 

mobile app to reset the internal clock time

F29

RTD Temperature 

Alarm

• Motor windings are getting hot

• Shut off the system to allow the PMA to cool down

F30

RTD Temperature 

Fault

• Motor windings are too hot

• Shut off the system to allow the PMA to cool down.
• Persistent faults may require pulling the PMA and installing a 

cooling sleeve (AIM manual)

F31

Input Phase Loss

• DC bus ripple amplitude exceeds 

a set value

• Input phase imbalance and loss of phase may indicate similar 

issues

• Measure and confirm adequate voltage at the drive input (L1-

L2, L2-L3, and L3-L1).

• Confirm input power leads are properly inserted into the input 

power terminal block and confirm proper torque.

F32

No Motor

• All three phases have current 

below 15% of motor FLA for 
250 ms

• Motor circuit has open or loose 

connection

• Troubleshoot motor
• Tighten motor connections

F35

Incompatible Firm

-

ware

• Firmware of Power board and 

Control board are incompatible

• Update firmware of boards to latest version
