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

VDC COMMUNICATION ERROR.

The panel sent a command to its main communication module and got no reply. It only comes up on machines with the variable rate sprinkler option or a position encoder. It stops the machine only if position loss shutdown is turned on.

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.
