What is an OLF fault code on an ATS22 softstart?

What does an OLF fault code mean on the ATS22 soft starters?

Product Line:
Altistart ATS22


OLF means motor overload fault

To reset the fault you can go into the Pro menu and find ITH parameter.  Set this to OFF and power cycle to get rid of the fault.
When power is reapplied, go back to the same parameter and turn it back to value desired for class protection.
Another option is to wait until enough time passes with the softstater power on.

Check the motor for blockage, phase rotation etc.
Check the ACC and tHP settings in SET menu, if ACC= 10 seconds or more,  try adjusting  the tHP to class 20 or class 30.
