Overload

What does 82 mean?

An overload situation has been detected by the R&M Materials Handling Frequency Converter, meaning the load on the motor exceeds its rated capacity. This can be caused by excessive physical load, worn mechanical components like the chain drive, or a faulty/miscalibrated load sensor.

• Load on hook exceeds the rated load
• Worn chain or chain drive (in chain hoists)
• Load sensor is out of calibration
• Load sensor has failed
• Mechanical failure in the gear system (in chain hoists)

Click steps to track your progress.

1. 1

   Verify that the load on the hook does not exceed the rated load capacity

2. 2

   Check and replace the chain and chain drive if worn

3. 3

   Recalibrate the load sensor by performing the load calibration function

4. 4

   If the problem recurs after recalibration, replace the load sensor and perform offset correction and calibration

5. 5

   Check hoist gear operation for unusual noise or vibration, indicating mechanical failure
