Functions &
Features
Notes:
1. The default is 60 seconds. The range is 0 - 3600 seconds.
5. Configure the Config Speed Min setting.
The PumpSmart PS220 can be configured to run at either minimum speed or stop when “Alarm and Control” has been
configured as the Response for the Pump Protection selection. The choices are:
1. The Minimum Speed set in Parameter 30.11. (SPD=MIN)
2. ZERO (0) RPM or to stop. (Speed =0)
Notes:
1. This choice cannot be selected for individual Responses. This is applied “globally” when selected.
2. The selection “Zero” should not be used if “Min-Speed” is selected for the PID sleep function in Process Control. The
sleep function will need to be changed to “INTELL SLEEP”. Refer to the Sleep function in this manual.
6. Configure the Stop Delay Min Speed.
When an upset condition triggers a Pump Protection Warning, the PumpSmart PS220 can be configured to run at its min-
imum speed for a timed duration. If the condition that triggered the warning has not cleared during this time, the drive
will either try to reset and run again, based on the number of error resets from step 4, or fault off and stop. This is not a
re-settable fault. The fault will have to be reset, and the drive issued a start command again. Please refer to the section
“Fault Tracing” in this manual.
Pump Protection
The PS220 Pump Protection functionality can be configured to fully identify, notify, control, and prevent a pump
in a system that may operate in an underload, or overload conditions, and all the adverse conditions of dry-run,
dead-head, minimum flow, runout, and cavitation. It can also provide the pumping system protection to ensure
that indirect damage from conditions such as over pressure, water hammer, and liquid temperature rise will not
occur. The onboard logic can also monitor external devices that are an integral part of the pumping system to
add an additional level of protection as well.
The PS220 offers 2 forms of this protection. They are:
1. Basic Pump Protection.
The Basic Pump Protection functionality uses the Process Control feedback to determine when upset conditions
may be occurring in the system. Depending on the Process Control Mode, it is “Sensorless”.
2. Advanced Pump Protection.
The Advanced Pump Protection functionality uses the PumpSmart PS220’s feedback from SmartFlow to deter-
mine when upset conditions may be occurring in the system. This protection is “Sensorless”. A flow meter can
also be used for this protection
NOTE:
The Basic Pump Protection choice and the Advanced Pump Protection choice cannot both be used together.
