Rainfall 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 after enough rain fell and stays off for a set number of days.

Once accumulated rainfall reaches the programmed amount, or a day counter runs out, the machine shuts down and stays down for the programmed number of days before the reading clears and it restarts on its own. Both the stop and the later restart are the option working, not a fault. The wait can be skipped by clearing the accumulated reading by hand. Because it can start again with nobody at the panel, treat a machine stopped this way as live. Shut off and lock out power at the main disconnect before anyone works on or around it.

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.
