Low/High Flow Shutdown on the Zimmatic BOSS
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
The machine stopped because flow through the system was too low or too high.
A delay time holds off this shutdown for a set period after a low or high flow reading first appears, so the machine stopping several minutes after the flow problem started is that delay running out, not a new problem. A wrong pulses-per-gallon setting for the flow meter can also cause nuisance low or high flow alerts on its own.
This one stops the machine.
This is what it means on the Zimmatic BOSS. On a different panel the same light or message can mean something else. Wrong panel? Pick another Zimmatic 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.
