404 on the Zimmatic FieldNET Pivot Control
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
Position Warning: the machine is drifting off its GPS position.
A 400-series code is a warning before a possible shutdown. The pivot is still running. If this keeps coming back, something is getting in the way of the GPS: noise from a VFD (variable frequency drive) or strobe lights, another pivot within 1500 feet set to the same communication channel, the GPS receiver itself, or the link between the receiver and the panel. If the position is fine running dry but the warning shows running wet, with the pump and drive motors on, that usually points to VFD noise.
404 on other panels
This page is for the Zimmatic FieldNET Pivot Control. The same code on another panel can mean something else:
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.
