7. Configure the Runout Flow Value
This value should be the maximum flow value as recommend by the Pump Manufacturer. It should be at
the rated full speed of the pump. The graphic above depicts this value on a pump performance curve. It is
typically the flow value directly below and to the right of the last line of efficiency, for the rated diameter of
the pump. It is approximately 10 to 25% greater the BEP Best Efficiency Point (BEP) flow.
The table below lists all of the parameters used with the Basic and Advanced Pump Protection functionality.

DESCRIPTION
The PS220's reaction to a Basic Pump Protection Event.
Protection is disabled
The PumpSmart PS220 will issue a warning message of "Basic Pump Protection". The
pump will continue to run at the maximum allowed speed while not achieving the
setpoint requirement.
The PumpSmart PS220 will either :
A. Issue a warning message, and either run at minimum speed or stop. It can be
configured to automatically re-start after a delay period and then run to maintain the
process setpoint. It can be configured to follow this routine a set number of times
before a hard Fault is issued. The Fault will have to be reset, and manually restarted.
B. A hard Fault is issued, and it will stop. The fault message will be displayed, and it will
have to be reset, and manually restarted.
The Pump Protection limit is the percentage value difference between the operating
setpoint, and the actual setpoint, at which the Basic Pump Protection Function
becomes active. The default value is 97%. Setting range: 0.0 – 100.0% of setpoint.
This is the protection delay period prior to activation of Pump Protection. Setting
range: 0– 200 sec. Default is 0
Selects if Pump protection warning and faults are enabled when the Speed Override
function is activated.
Protection is inactive.
Protection is active
Determines the number of automatic fault resets or retries allowed before a fault
condition will become active. Selection range is 0 – 19. The Default is 0. A "0" also
deactivates this function.
The counter resets if a stop command is issued or the condition has passed and the
PS220 runs without further incident for 5 minutes.
Not Applicable for DRY RUN.
Defines the time that the PS220 will wait before attempting an error reset. Setting
Range = 0 -3600 sec. Default is 60 Seconds
Identifies the source of the flow readings used in Pump Protection
The PS220 will use the Smartflow calculated flow value.
The PS220 will use the flow value from an external flow meter.
The PS220's reaction to a Minimum Flow Event.
Protection is disabled.
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.
The PumpSmart PS220 will indicate that the pump is running at or below minimum flow
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
Protections Options. If and when a hard fault occurs it will display the message "Min
Flow Fault". The PS220 will have to be reset and manually restarted.
Defines the safe minimum flow of the pump at pump rated speed.
The PS220's reaction to a Dry Run Event. The information entered with the Smartflow
Configuration Wizard will automatically determine the value used for this protection's
response
Protection is disabled.
The PumpSmart PS220 will fault off with the message "Dry Run Fault" when conditions
are satisfied based on the configuration of the "Protection Options". The event will be
stored in the event log. This fault is not an Auto-resettable fault. The PS220 will have to
be reset, and manually restarted.
The PumpSmart PS220 will respond with the message "Dry Run Warning" when
conditions are satisfied based on the configuration of the "Protection Options". The
event will be stored in the event log. This warning message will clear when operating
conditions return to normal. No further action will be taken.
The Dry Run factor is for "fine tuning" the Dry Run fault feature. It should only be
adjusted during initial commissioning to test the Dry Run Response function. Normally
this parameter requires no adjustment. When adjustment may be required this value
should only be changed in increments of 1/100
.95.
The PS220's reaction to a Runout Event.
Protection is disabled.
The PumpSmart PS220's only response is to provide a warning.
