The PumpSmart PS220 can identify when a Minimum flow event is occurring and provide several responses as
noted below:
When configuring the use of the Minimum Flow Control you will need to select a Response and define the
actual Minimum flow value.
The choices are:
A. Disabled (Default)
The PumpSmart PS220 will continue to run. There will not be any indication of this event.
B. Alarm (Warning).
The PumpSmart PS220 will continue to run. The warning message “Min Flow Warning” will display. The event
will be stored in the Event Log. It will
continue to indicate the warning until the flow increases to a value
above minimum flow.
C. Alarm & Control
The PumpSmart PS220 will indicate that the pump is running at or below minimum with a message “Min Flow
Warning”. After the response delay time has expired. The event will be stored in the Event Log. The PS220 will
then respond based on the configured Protections Options. When a Hard Fault occurs, it will display the mes-
sage “Min Flow Fault”. It will have to be reset and manually restarted.
Please refer to the section “Fault Tracing” and “Protection Options” in this manual for more information on
these topics.
