Auto Restart
The PS220 can be configured to automatically restart on conditions such as Power Failure, VFD faults, and
Pump Protection faults. It can be set to reset a fault(s) up to a limited number of sequential attempts. If after
these attempts the Fault condition did not clear or could not be reset the drive will produce a “Hard” Fault and
will have to be manually reset. See the Section on Fault Tracing in this Manual for further information on how
to restart the drive after these events.
By enabling 74.02 AUTO RESTART, 31.14 AUTO RESET TRIALS or 79.05 PUMP FAULT RESET functions
the driven equipment will automatically restart from either a power failure or fault condition if a start
signal is present. All precautions should be taken to ensure the driven equipment can be automatically
restarted. Failure to follow these instructions may result in physical injury or equipment damage.
