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