3. Intelligent Sleep. This selection will utilize the pumps minimum flow value from an external flow
meter, or from SmartFlow. With this choice the pump will Sleep when the values of “Sleep Value”,
“Minimum Flow”, and the “Sleep Delay” have all been achieved. The PS220 will use internal logic to
correctly determine the minimum flow as speeds change.
When selecting Intelligent Sleep, the “Meshing Gears” animation will also be displayed.
Additional Wizards noted below may need to be run when configuring the Intelligent Sleep selection
to function correctly.
1. SmartFlow Wizard if being used for this value for flow.
2. Pump & VFD Protection Wizards if an external flowmeter is used that is not the primary process
control transmitter selected previously.
The Sleep Function will require that the following parameters to be configured:
1. Sleep Value
100% is the default value. This is the actual value as a percentage of the process setpoint that the
system will need to read before the sleeping logic will work. It can be adjusted.
2. Restart Value
90% is the default value. This is drop in actual value of the process, as a percentage of the process set-
point, that the system will need to read before it can “Wake-Up” and pump again. It can be adjusted.
4. Sleep Delay
5 Seconds is the default value. This is the time value that the system will need to wait before it will go
to sleep after the “Sleep Value” and either “Min Flow” or “Min Speed” have been achieved. It can be
adjusted.
5. Restart Delay
10 Seconds is the default value. This is the time value that the system will need to wait before it will
“Wake -Up“ after the “Restart Value” has been achieved. It can be adjusted.
