Lightning bolt symbol on the Valley Select
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
Power failed or voltage dropped too low.
Power to the machine was cut off, or voltage fell below 440 volts. Below 440 the machine will not restart. A normal reading in the voltage window now does not rule out low voltage, because voltage can dip for a moment while running and shut the machine down. The symbol records what happened, not what is happening right now. On an engine-driven machine, watch whether the generator holds voltage under load. If the Auto Restart switch is on, the machine can start again by itself when power comes back, and a flashing dELAY on the display means it may start at any time. Treat it as live and stay clear of it.
Call a technician for this one, rather than opening the panel.
This is what it means on the Valley Select. On a different panel the same light or message 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.
