Er15 on the Valley Precision Corner
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
Auto correct failed.
The machine is stuck, or the variable speed drive has malfunctioned. Once the reason it stuck is found and fixed, such as a flat tire or a wheel hung up on a ridge, an operator may try an auto correct at the steerable drive unit, following the operating instructions that came with the machine. The corner moves by itself during an auto correct, so keep everyone clear. Never try it with the pump running. If the cause cannot be found, or the auto correct does not clear it, call your dealer.
Only the corner's own operator controls are for the operator. Wiring, sensors and anything electrical are work for a technician.
This is what Er15 means on the Valley Precision Corner. On a different panel it can mean something else. Wrong panel? Pick another Valley 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.
