VFD FAULT RESET
The Fault Reset screen (Figure 4-16) informs the operator of the readiness of each VFD—Faulted
or No Fault—and permits resetting a faulted VFD. The screen may be selected from either the
Home, Clean Out, or Operation screen. After a bowl or conveyor VFD fault, be sure that the
centrifuge has come to a complete stop before attempting to re-start.
