Auto Reset (VFD)
The PumpSmart PS220 can be configured to automatically reset specific VFD related faults. The drive will follow a routine
of faulting, waiting, and automatically resetting up to five time within a pre-determined amount of time. After this time if
the condition(s) still exists the PumpSmart PS220 drive will issue a “Hard” fault and will have to be manually restarted.
Please refer to the Pump and VFD Protection Wizard for more specific detail on how to set these parameters with your
pumping system. To access this wizard from the home view, follow the path: Menu>PS220 Configuration> Pump &VFD
