Valley Precision Corner error codes
An independent guide from FixMyPivot, not from the manufacturer. Brand and panel names are here only so you can find your own equipment.
19 listed for this panel. Tap one for the full explanation. These only apply to this panel. On a different panel the same code, light or message can mean something else.
Most corner arm faults need a technician. Knowing the code helps the technician when you call. If more than one fault is active, the display shows the lowest numbered code first, and the next one shows once that one is cleared. FixMyPivot does not troubleshoot corner arms.

Safety
Center pivots run on high voltage and heavy moving machinery. Shut off and lock out power at the main disconnect before you open a panel or touch anything electrical. If you are not sure, stop and call your local pivot dealer or a licensed electrician. These pages tell you what a code means. They do not replace a qualified technician, and the safety instructions that came with your equipment come first.
