STATUS VALUES CHAPTER 4: FUNCTIONALITY

• Motor Hrs: The LM10 keeps a running tally of motor operation time, incremented

hourly up to 65535 hours. Upon power loss, the unit will retain any whole number of

hours already recorded. This feature is a great service tool. An example is for bearing

change; the typical maximum bearing life is 50000 hours.

This value can be reset via the Reset Run Hrs configuration setting.
