2.2 Standard System Configurations
2.2.1 Stand-Alone System Configuration
The stand-alone configuration of the PuraLev
®
2000SU pump system (see 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 analogue signal.

2.2.2 Extended System Configuration
The extended version of the PuraLev
®
2000SU pump system (Figure 4) consists of a controller with an
extended PLC interface. This allows setting the speed by an external signal (see Position 3b in Table 2) 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.
