Er16 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
Span sensor fault.
The corner span has pushed together or pulled apart past its limit. The steerable drive unit is too close to the last regular drive unit, or too far from it. Once the reason it stopped is found and fixed, such as a flat tire, a bad gearbox, or the steerable drive unit stuck or sliding on a ridge, an operator or the dealer may try an auto correct, 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 corner safety fault light is on too, or the code does not clear or comes back, 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 Er16 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.
