What to do if Eaton 66D2032G01 Relays show IOC GND FLT?
- D
  David GomezAug 22, 2025
  If your Eaton Relays display 'IOC GND FLT', it indicates an electrical fault (short circuit) in the insulation of the motor or connecting circuits. As a precaution, shut down and lock out the motor. It's crucial to seek expert assistance to evaluate the motor's condition and determine the necessary repairs. Avoid attempting a restart without a professional assessment. After the motor has been repaired or replaced, remember to inspect the fuses in the starter and replace any that have blown.

  A 'GND FAULT' on Eaton Relays signals an insulation failure leading to ground current leakage. This situation poses a danger. Immediately stop and isolate the motor to prevent further damage or more hazardous conditions. It is essential to get an expert evaluation of the motor's insulation condition.

What does PH UNBAL mean on Eaton 66D2032G01 and what should I check?
- M
  micheleparsonsAug 26, 2025
  If you see 'PH UNBAL' on your Eaton Relays, it means there's a phase unbalance, possibly due to source voltage unbalance from a remote fault or single-phase loading, or single phasing of the motor. Check the voltage balance and the integrity of feeder connections. Also, inspect the fuses in the starter. Do not attempt to restart until the cause of single-phasing is found.

What should I do if my Eaton 66D2032G01 display WD TEMP MB TEMP LB TEMP AX TEMP?
- E
  Elizabeth BarryAug 27, 2025
  If your Eaton Relays show 'WD TEMP MB TEMP LB TEMP AX TEMP', it means the temperature is at or above the alarm setpoint value. Check the specific value in Monitor mode to find the cause. Stator heat could be from overload or blocked cooling airflow. Bearing heat often means a failure is coming or there's not enough lubrication.

What does JAM mean on Eaton 66D2032G01 Relays and how to resolve it?
- J
  John SmithAug 27, 2025
  If 'JAM' appears on your Eaton Relays, it indicates a malfunction or jam in the driven process equipment. Ensure safety by locking out the motor starter and then inspect the process equipment to identify and resolve the jam.

What does MB TEMP LB TEMP WD TEMP AX TEMP mean on Eaton Relays?
- B
  bmayoAug 29, 2025
  When Eaton Relays display 'MB TEMP LB TEMP WD TEMP AX TEMP', it suggests a failure in the bearings or bearing lubrication system. Also, check the RTD integrity. Sustained overloading of the motor or cooling air flow blockage can also cause this. If the RTD is okay, the bearing will likely need replacement. Inspect the airflow path, look for causes of abnormal loading, and check for abnormal supply voltage.

What does %I2T mean on Eaton 66D2032G01 Relays and how can I fix it?
- M
  Melissa GilbertAug 30, 2025
  The '%I2T' message on Eaton Relays indicates that the thermal-model bucket level has exceeded the alarm setpoint, which is between 60 to 100% of the trip level. You should determine if the motor is experiencing a larger than expected sustained load. Check for any unbalance in supply currents or voltages that could cause negative-sequence heating. Also, verify the system voltage level and inspect for cooling air blockage or abnormal ambient conditions. Monitor the bucket level in Monitor mode to ensure it doesn't continue rising to the trip level.

What to do if Eaton Relays show PH REVRS?
- R
  Robert ClarkSep 1, 2025
  If Eaton Relays display 'PH REVRS' at startup, the phase sequence is reversed. Since the MP-3000 is set for a non-reversing starter, the motor should never run backwards. A possible cause is swapped phases in the incoming source. Correct this by swapping two of the incoming power leads (L1, L2, or L3). Another cause could be swapped phases in the CT wiring. Check the wiring at both the CT and relay ends. You can change the MP-3000 current transformer wiring by swapping the current transformer wiring terminals H1B-H2B with H1C-H2C. Clearly mark the new wiring and update the drawings for future reference. Also, check the motor for the correct direction of rotation at the moment of starting.

What does STEX A mean on Eaton 66D2032G01 Relays and what is the solution?
- C
  Christopher GutierrezSep 2, 2025
  If your Eaton Relays display 'STEX A', it means that all of the allowed starts within the set time period have been used. To resolve this, wait the number of minutes shown on the display before attempting to restart the system.

Why does my Eaton 66D2032G01 display LRC/I2T?
- M
  markmcconnellSep 3, 2025
  If your Eaton Relays display 'LRC/I2T', it means the thermal-model bucket has reached the trip level. Note that this trip cannot be reset until the thermal-model bucket has cooled below the user-set I2T alarm level. Determine if the motor is experiencing a larger than expected sustained loading. Check for unbalance in supply currents or voltages causing negative-sequence heating. Also, check for abnormal system voltage level and inspect for cooling air blockage or abnormal ambient conditions.
