Pressure Switch light on the Zimmatic AIMS Basic

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

Should be on in Dry, and in Wet it comes on only once the pressure switch sees water pressure.

With the Wet-Dry switch in Dry, the pressure switch is bypassed and this light should be on. Off there usually means the On-Off switch is Off. A failed Wet-Dry switch can do it too, and that is a job for a technician. With the Wet-Dry switch in Wet, the light stays off until the pressure switch closes, so off while running wet means the panel is not seeing water pressure.

This is what it means on the Zimmatic AIMS Basic. 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.
