ALARM AND FAULT MESSAGES
Cause Corrective Action
F3021 - Pump Motor Thermal Overload Check Pump Motor Temperature and Thermistor
Pump drive motor shut down due to
high temperature or defective thermistor
in motor winding
Check motor temperature. Allow motor to cool, and
then check for continuity across thermistor leads. If
open circuit is found, replace motor.
Bad connection(s) Check connections at TB2-3 and 4, at
transmitter/intrinsic barrier, and at pump VFD.
Correct as required. Replace motor if no defects are
found.
F3022 - Pump Bearing/Stator Thermal Overload Check Pump Bearing Temperature and
Stator
Pump drive motor shut down due to
high bearing temperature or high
temperature in stator winding
Check motor bearing temperature. Allow motor to
cool, and then check for continuity across stator
thermistor leads. If open circuit is found, replace
motor.
Bad connection(s) Check connections at TB2-3 and 4, at
transmitter/intrinsic barrier, and at pump VFD.
Correct as required. Replace motor if no defects are
found.
F3030 - Pump Motor FLA Download to VFD Failed

successfully completed
Repeat pump motor data download procedure. Verify
that pump drive is on line and stopped.
F3031 - Pump Motor Power Download to VFD Failed
Pump motor power download was not
successfully completed
Repeat pump motor data download procedure. Verify
that pump drive is on line and stopped.
F3032 - Pump Motor Power Units Download to VFD Failed

F4001 - Centrifuge Start Disable - Allow Bowl to Stop Completely, View Alarm History for
Additional Fault Conditions
Restart aborted due to bowl rotation
during restart attempt
Wait for bowl to fully stop, check for and clear all
faults, and verify that bowl is at complete standstill.
Restart centrifuge.
F4002 - Clean Out Over Torque Fault
Excessive torque has caused clean out
procedure to abort
Attempt to clear using Manual Cleanout procedure in
this section. If unsuccessful, connect a liquid supply
line to flush fitting to dilute process material, and re-
attempt Manual Cleanout. If still unsuccessful, with
bowl at complete standstill, open cover and remove
excessive process material.
