2.2 System Overview and General Specification
2.2.1 Stand-Alone System Configuration
The stand-alone pump system configuration (Figure 3), consists of a controller with an integrated user panel
to set the speed manually. The speed is automatically stored in the internal EEPROM of the controller. As an
option, the speed can also be set with an analog signal.

(Speed setting with integrated user panel)
2.2.2 Extended System Configuration
The extended version of the pump system (Figure 4) consists of a controller with an extended PLC interface.
This allows setting the speed by an external signal and enables precise closed-loop flow or pressure control
in connection with either a flow or a pressure sensor. A USB interface allows communication with a PC in
connection with the Levitronix
®
Service Software. Hence parameterization, firmware updates and failure
analysis are possible.
