FAULT RESET SCREEN
The Fault Reset screen (Figure 4098-14) displays the operational condition of all three VFDs. It
may be selected from either the Clean Out or Operation screen. If high conveyor torque causes a
reduction in the pump flow rate, the message “Flowrate Reduction” is displayed on the Operation
or Clean Out screen to inform the operator that the pump is operating at a reduced flow rate. This
message also appears on the Fault Reset screen. After removing the cause of the reduced flow
rate, RESET is selected on the Fault Reset screen to return the pump to the normal flow rate.
After any fault, be sure that centrifuge has come to a complete stop before attempting to re-start.
