E12 on the Valley Pro / Pro2
An independent guide from FixMyPivot, not from the manufacturer. Brand and panel names are here only so you can find your own equipment.
What it means on the Pro2
Resolver out of range high.
The panel is getting no usable signal from the position sensor (the resolver). A sensor left unplugged after service work, or after the collector ring has been apart, is a common cause, and so are loose or shorted wires to it. While this is showing, end guns, stop in slot and anything else that runs by position will act up at the same time.
Call a technician for this one, rather than opening the panel.

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.
