Control Modes. (Process PID Control)
The PumpSmart PS220 use can be configured to operate in a specific control mode using internal PID control
functionality. This will allow a pumping system to maintain a stable rate of control to a defined setpoint, or
reference. Based on the feedback supplied from wired or “Sensorless” transmitters, it will react immediately
to any changes that may occur on both the suction and discharge side of the pump, automatically stabilizing
the system.
Only a few steps are required to enable this control.
This control can only be enabled through the use of the PS220 Configuration Wizard. Basic Startup must be
configured prior to enabling and fully configuring the Control Mode.
There are 4 steps to full configure the Control Mode. They are:
1. Configure the Control Mode.
2. Configure the Control Modes unit of measure.
3. Configure the Regulation Mode of the Transmitter to be used.
4. Configure all of the Transmitters detail.
5. Configure the scaling of the Setpoint.
6. Configure the source for the Setpoint
1. Configure the Control Mode
The PumpSmart PS220 can be configured to operate in the following Process Control Modes.
1. Pressure.
The PumpSmart PS220 will maintain constant pressure regulated to a setpoint. A pressure transmitter will
need to be connected and configured for use.
2. Flow.
The PumpSmart PS220 will maintain constant flow rate regulated to a setpoint. A flow transmitter will need
to be connected and configured for use.
3. SmartFlow.
The PumpSmart PS220 will maintain constant flow regulated to a setpoint. A flow transmitter will not be
required. Feedback will be transmitted internally using the SmartFlow functionality to determine actual flow.
Smartflow configuration will required.
4. Level.
The PumpSmart PS220 will maintain constant level regulated to a setpoint. A level, (or pressure that can be
converted to level), transmitter will need to be connected and configured for use.
5. Temperature.
The PumpSmart PS220 will maintain constant temperature of the process fluid regulated to a setpoint. A
temperature transmitter will need to be connected and configured for use.
6. Smart TDH.
The PumpSmart PS220 will maintain a constant Total Dynamic Head (TDH) using internal TDH calculations
to a setpoint. A TDH transmitter will need to be connected and configured for use. It will not require the use
of a suctions side transmitter if the suction pressure is relatively stable. If the suction pressure does vary this
control mode will require both a suction and discharge transmitter to be connected, and fully configured for
use. It will also require the configuration of the Advanced SmartFlow Functionality.
